retina display vs tft lcd supplier

New Delhi: The technology used in mobile displays in the modern day smartphones has progressed significantly. In the era of touchscreen  smartphones, the display technology has become one of its primary selling points, and certainly its most unique feature. Not only we want the touch screens to offer crisp text, vibrant images, blur-free video and enough brightness, we want them at low cost too.

For instance, HTC One uses Super LCD3 tech, in its 4.7in screen which gives a resolution of 1920 x 1080 pixels, with pixel density of 469 pixels per inch (ppi). This results in super display in terms of crispness and colour reproduction. HTC says the SLCD technology gives the phone better power management, improved viewing angles and is easier to produce.

The Thin film transistor liquid crystal display (TFT LCD) technology is the most common display technology used in mobile phones. A variant of liquid crystal display (LCD), the technology uses TFT technology to enhance image quality. It offers better image quality and higher resolutions as compared to earlier generation LCD displays.

IPS LCD Stands for In Plane Switching liquid Crystal Display. This technology offers better display quality as compared to the TFT-LCD display. The good part about IPS LCD is that it offers better viewing angles and consumes less power. Due to higher costs, it is found only on high-end smartphones. Apple uses a high resolution (640x960 pixels) version of IPS LCD in its iPhone 4, which is also called Retina Display.

Organic Light Emitting Diode (OLED) display technology is much better as compared to the LCD display technology because of its excellent colour reproduction, faster response times, wider viewing angles, higher brightness and extremely light weight designs.

OLEDs are brighter than LEDs and do not require backlighting like LCDs. Since OLEDs do not require backlighting, they consume much less power than LCDs.

Since these display forms are easier to produce, they can be made to larger sizes. Because OLEDs are essentially plastics, they can be made into large, thin sheets.

AMOLED screens have all the attributes of an OLED display like excellent colour reproduction, faster response times, wider viewing angles, higher brightness and extremely light weight designs.

Super AMOLED display technology is an advanced version of AMOLED display. Samsung uses this term for the AMOLED panels that they develop. Super AMOLED  screens are built with capacitive touch sensors on the display itself. Super AMOLED display is much more responsive than an AMOLED display. Samsung top-of-the-line Galaxy SII comes engineered with Super AMOLED display technology. Samsung has already took it"s SMOLED screen to next levels by developing Super AMOLED+, HD Super AMOLED+ and FHD Super AMOLED+ screens.

It is a name given by Apple to the high-resolution screen technology introduced on the iPhone 4 in June 2010. Something is a Retina Display when it offers a density of pixels above 163 pixels per inch. The company calls it the Retina display because its pixels cannot be individually identified by a human eye, thus rendering a super sharp display, more crisp text and more clear pictures.

Retina Display is designed to smooth the jagged edges of pixels are provide a higher-quality image than previously available on mobile devices. Apple claims that its resolution is so good that it makes it impossible for the human eye to distinguish individual pixels. Its effects shows up in text, images and videos.

Color boost is simply Moto"s marketing term for their new display. Although it now uses LCD displays, the company fine-tuned its panels to match the saturation of OLED displays while maintaining the higher performance of LCD. It"s somewhere in the middle ground.

IPS (In-Plane Switching) lcd is still a type of TFT LCD, IPS TFT is also called SFT LCD (supper fine tft ),different to regular tft in TN (Twisted Nematic) mode, theIPS LCD liquid crystal elements inside the tft lcd cell, they are arrayed in plane inside the lcd cell when power off, so the light can not transmit it via theIPS lcdwhen power off, When power on, the liquid crystal elements inside the IPS tft would switch in a small angle, then the light would go through the IPS lcd display, then the display on since light go through the IPS display, the switching angle is related to the input power, the switch angle is related to the input power value of IPS LCD, the more switch angle, the more light would transmit the IPS LCD, we call it negative display mode.

The regular tft lcd, it is a-si TN (Twisted Nematic) tft lcd, its liquid crystal elements are arrayed in vertical type, the light could transmit the regularTFT LCDwhen power off. When power on, the liquid crystal twist in some angle, then it block the light transmit the tft lcd, then make the display elements display on by this way, the liquid crystal twist angle is also related to the input power, the more twist angle, the more light would be blocked by the tft lcd, it is tft lcd working mode.

A TFT lcd display is vivid and colorful than a common monochrome lcd display. TFT refreshes more quickly response than a monochrome LCD display and shows motion more smoothly. TFT displays use more electricity in driving than monochrome LCD screens, so they not only cost more in the first place, but they are also more expensive to drive tft lcd screen.The two most common types of TFT LCDs are IPS and TN displays.

As you might already be aware, there’s a large variety of versatile digital display types on the market, all of which are specifically designed to perform certain functions and are suitable for numerous commercial, industrial, and personal uses. The type of digital display you choose for your company or organization depends largely on the requirements of your industry, customer-base, employees, and business practices. Unfortunately, if you happen to be technologically challenged and don’t know much about digital displays and monitors, it can be difficult to determine which features and functions would work best within your professional environment. If you have trouble deciphering the pros and cons of using TFT vs. IPS displays, here’s a little guide to help make your decision easier.

TFT stands for thin-film-transistor, which is a variant of liquid crystal display (LCD). TFTs are categorized as active matrix LCDs, which means that they can simultaneously retain certain pixels on a screen while also addressing other pixels using minimal amounts of energy. This is because TFTs consist of transistors and capacitors that respectively work to conserve as much energy as possible while still remaining in operation and rendering optimal results. TFT display technologies offer the following features, some of which are engineered to enhance overall user experience.

The bright LED backlights that are featured in TFT displays are most often used for mobile screens. These backlights offer a great deal of adaptability and can be adjusted according to the visual preferences of the user. In some cases, certain mobile devices can be set up to automatically adjust the brightness level of the screen depending on the natural or artificial lighting in any given location. This is a very handy feature for people who have difficulty learning how to adjust the settings on a device or monitor and makes for easier sunlight readability.

One of the major drawbacks of using a TFT LCD instead of an IPS is that the former doesn’t offer the same level of visibility as the latter. To get the full effect of the graphics on a TFT screen, you have to be seated right in front of the screen at all times. If you’re just using the monitor for regular web browsing, for office work, to read and answer emails, or for other everyday uses, then a TFT display will suit your needs just fine. But, if you’re using it to conduct business that requires the highest level of colour and graphic accuracy, such as completing military or naval tasks, then your best bet is to opt for an IPS screen instead.

Nonetheless, most TFT displays are still fully capable of delivering reasonably sharp images that are ideal for everyday purposes and they also have relatively short response times from your keyboard or mouse to your screen. This is because the pixel aspect ration is much narrower than its IPS counterpart and therefore, the colours aren’t as widely spread out and are formatted to fit onto the screen. Primary colours—red, yellow, and blue—are used as the basis for creating brightness and different shades, which is why there’s such a strong contrast between different aspects of every image. Computer monitors, modern-day HD TV screens, laptop monitors, mobile devices, and even tablets all utilize this technology.

IPS (in-plane-switching) technology is almost like an improvement on the traditional TFT display module in the sense that it has the same basic structure, but with slightly more enhanced features and more widespread usability. IPS LCD monitors consist of the following high-end features.

IPS screens have the capability to recognize movements and commands much faster than the traditional TFT LCD displays and as a result, their response times are infinitely faster. Of course, the human eye doesn’t notice the difference on separate occasions, but when witnessing side-by-side demonstrations, the difference is clear.

Wide-set screen configurations allow for much wider and versatile viewing angles as well. This is probably one of the most notable and bankable differences between TFT and IPS displays. With IPS displays, you can view the same image from a large variety of different angles without causing grayscale, blurriness, halo effects, or obstructing your user experience in any way. This makes IPS the perfect display option for people who rely on true-to-form and sharp colour and image contrasts in their work or daily lives.

IPS displays are designed to have higher transmittance frequencies than their TFT counterparts within a shorter period of time (precisely 1 millisecond vs. 25 milliseconds). This speed increase might seem minute or indecipherable to the naked eye, but it actually makes a huge difference in side-by-side demonstrations and observations, especially if your work depends largely on high-speed information sharing with minimal or no lagging.

Just like TFT displays, IPS displays also use primary colours to produce different shades through their pixels. The main difference in this regard is the placement of the pixels and how they interact with electrodes. In TFT displays, the pixels run perpendicular to one another when they’re activated by electrodes, which creates a pretty sharp image, but not quite as pristine or crisp as what IPS displays can achieve. IPS display technologies employ a different configuration in the sense that pixels are placed parallel to one another to reflect more light and result in a sharper, clearer, brighter, and more vibrant image. The wide-set screen also establishes a wider aspect ratio, which strengthens visibility and creates a more realistic and lasting effect.

The quality of a mobile phone"s display is arguably the most important factor to consider when you establish a relationship with a handset. It"s inescapable, really. Whether you"re playing a rousing game of Robot Unicorn Attack or (regrettably) drunk-dialing an ex, it"s the one interface element that you"re consistently interacting with. It"s your window to the world and your canvas for creation, and if it"s lousy, it"s going to negatively influence everything you see and do. Today, we"re delving into the world of mobile displays, where we"re aiming to entertain and edify, and hopefully save you from making regrettable decisions -- when it comes to purchasing new phones, anyway.

In this edition of Primed, we"ll be examining the different qualities and underlying technologies of several displays, starting with the ubiquitous TFT-LCD and moving through the nascent realm of glasses-free 3D and beyond. We"ll also be addressing the importance of resolution and pixel density. Finally, we"ll be scoping out a handful of upcoming technologies -- while some are thoroughly intriguing, others are just plain wacky. Go ahead... buy the ticket, take the ride, and join us after the break. It"s Primed time.

Generally speaking, two display types rule today"s mobile phones: the Liquid Crystal Display (LCD), and the Organic Light-Emitting Diode (OLED). While each technology carries a set of strengths and weaknesses, a very important distinction can be drawn between the two. The LCD uses the light modulating properties of liquid crystals (LCs), but LCs don"t emit light directly. As such, a light source is necessary for proper viewing. Conversely, the OLED uses organic compounds that illuminate when exposed to electric currents. As backlights aren"t necessary for OLEDs, they"re significantly thinner than traditional LCDs. All things equal, OLED phones should be slimmer than their LCD counterparts, but this isn"t always the case. Take for example the MEDIAS N-04C, which uses a TFT-LCD and measures 7.7mm thin, versus the Galaxy S II, which uses the latest Super AMOLED Plus display and is 8.5mm thick.

The most desirable phone displays today are variants of these two technologies. In the LCD camp, there"s the Super LCD (S-LCD) and the IPS display -- with the latter as the basis for the Retina Display and the NOVA display. Likewise, the OLED territory is filled with options such as Super AMOLED, Super AMOLED Plus and ClearBlack. We"ll discuss the important distinctions between these competing display types shortly, but first let"s develop a fundamental understanding of how these brilliant creations work and how they came to be.

The story of the LCD began in 1888 when cholesterol was extracted from carrots. Think we reached too far back? Not if you"ve ever wondered what liquid crystals are. You see, a botanist named Friedrich Reinitzer discovered this extract had two distinct boiling points and observed the molecule"s ability to transmute from liquid to a crystalline structure in the interim. Even more shocking, the cloudy substance was able to reflect circularly polarized light and rotate the light"s polarization. (This little tidbit will become important when we discuss how LCDs operate.) While liquid crystals appear throughout nature, it wasn"t until 1972 -- when 5CB (4-Cyano-4"-pentylbiphenyl) was synthesized -- that they became commercially viable. A first of its kind, 5CB was chemically stable and entered its nematic phase at room temperature. While there"s actually three phases of liquid crystals, we"re most interested in the nematic one. This describes a state where molecules flow like liquid and self-align in a thread-like helix -- and coincidentally, are easily manipulated with electricity.

Now that you"ve got a little background about liquid crystals, let"s examine how they"re used in LCDs. Let"s start by making a sandwich. As our bread, we"ll take two polarizing filters, one which polarizes light on the horizontal axis and the other on the vertical axis. If we take the slices of bread and hold them up to a light source, nothing is going to pass through. Remember when we said liquid crystals have the ability to rotate light"s polarization? Yeah, they"re a critical ingredient in our sandwich because they determine light"s passage. When nematic crystals are in their natural (or relaxed) state, they form a twisted helix. As light travels through the molecule structure, its polarization is rotated by 90 degrees and light is allowed to pass through the top filter. Conversely, when voltage is applied to the LCs, the helix is broken and light can"t escape the polarizing filters. If you"re keeping score, this is known as the twisted nematic field effect. Going back to the sandwich analogy, the nematic crystals are placed between two layers of transparent electrodes which apply voltage to the liquid crystals. It"s a rather simplistic sandwich, but it describes the fundamentals of how LCDs work. For you visual learners, Bill Hammack does an excellent job of explaining these concepts in the following video.

Now let"s apply this knowledge to the modern TFT-LCD that you"re familiar with. It"s the basis for twisted nematic (TN) and in-plane switching (IPS) displays, and both technologies rely upon the thin film transistor (TFT) for the quick response time and image clarity that we take for granted. Fundamentally, the TFT is a matrix of capacitors and transistors that address the display pixel by pixel -- although at a blistering speed. Every pixel consists of three sub-pixels -- red, green and blue -- each with its own transistor, and a layer of insulated liquid crystals are sandwiched between conductive indium tin oxide layers. Shades are made possible by delivering a partial charge to the underlying LCs, which controls the amount of light that passes through the polarizing filter, thus regulating the intensity of each sub-pixel.

The most common LCD display is based on TN technology, which has been successful due to its relatively inexpensive production costs and fast refresh rates. Many of you will remember the shadow-trail that plagued early LCDs, and faster refresh rates reduce this effect and make the displays better suited for movies and games. Unfortunately, TN displays are famous for exhibiting poor viewing angles and most aren"t capable of showing the entire 24-bit sRGB color gamut. In attempt to mimic the full range of 16.7 million colors, many screens implement a form of dithering to simulate the proper shade. Basic TN screens are hardly fantastic, but they"re also good enough to survive the day without eliciting too many complaints.

IPS displays were created to resolve the long-standing problems of poor viewing angles and color reproduction of their TN counterparts. The fundamental difference between the two technologies is that liquid crystals run parallel to the panel rather than perpendicular. This alignment allows for wider viewing angles and more uniform colors, but at a loss of brightness and contrast. Traditionally, IPS panels were significantly more expensive than TN alternatives, but recent advances have lowered the production cost and improved the brightness and contrast issues. This technology is the basis for Apple"s Retina Display and the NOVA display -- both of which are manufactured by LG.

Another technology that"s gotten plenty of airtime is the Super LCD (S-LCD), which is a display that"s manufactured by a joint-venture between Sony and Samsung. It employs an alternate method to IPS and TN that"s known as super patterned vertical alignment (S-PVA). Here, the liquid crystals have varying orientations, which help colors remain uniform when viewed from greater angles. S-LCDs also feature improved contrast ratios over traditional TN displays, which exposes a greater amount of details in dark images. Further, these displays feature dual sub-pixels that selectively illuminate based on the brightness of the screen. As you can imagine, this provides power-saving benefits, along with refined control of colors on the screen.

Now, let"s take a look at OLEDs, which are a staple of many high-end phones today. As we"ve mentioned, these displays operate without a backlight. Instead, they use electroluminescent organic compounds that emit light when they"re exposed to an electric current. The main advantages of OLEDs include deeper black levels (because there"s no backlight), enhanced contrast ratios, and excellent viewing angles, while drawbacks include reduced brightness and colors that are often over-saturated. OLED screens also suffer an awkward aging effect, where the red, green and blue sub-pixels will deteriorate and lose efficiency at different rates, which causes brightness and color consistency to worsen over time. While improvements are being made, it"s important to understand that this display technology is still relatively immature.

You"re most likely familiar with the active-matrix OLED (AMOLED), which relies on a TFT backplane to switch individual pixels on and off. Coincidentally, active-matrix displays consume significantly less power than their passive-matrix OLED (PMOLED) counterparts, which makes them particularly well-suited for mobile devices. These displays are typically manufactured by printing electroluminescent materials onto a substrate, and that relatively simplistic process suggests that OLEDs will ultimately become cheaper and easier to manufacture than LCDs. Shockingly, the most challenging step is the creation of the substrate itself, which remains a difficult and expensive endeavor. Currently, the limited supply and high demand of AMOLED screens has restricted their availability, and you"re most likely to find them in high-end smartphones.

While all screens suffer from reduced visibility in direct sunlight, the original AMOLED screens were particularly vulnerable to this drawback. To resolve this, Samsung introduced the Super AMOLED display. With this new technology, the touch sensors were integrated into the screen itself. Naturally, this allowed for a thinner display, but this also improved brightness by eliminating the extra layer. Additionally, the screen"s reflection of ambient light and power consumption were significantly reduced. While colors were now bright and vibrant -- and acceptable in direct sunlight -- the displays still couldn"t match the crispness and clarity of LCD screens, particularly with respect to text. Samsung"s PenTile matrix is to blame, which is a hallmark of its AMOLED and Super AMOLED displays. Here, a single pixel is composed of two sub-pixels, either red and green, or blue and green, and the green sub-pixel is significantly more narrow than the other two. While the scheme works fine for images because the human eye is more sensitive to green, it makes the anti-aliasing of text rather imprecise, and the end result is a bit blurry. Like Super AMOLED, Nokia"s ClearBlack display was created to make the AMOLED screen more visible in direct sunlight. This was accomplished by adding a polarized filter to the display, which allows the viewer to see through the screen"s reflection and view the images as they would appear under more ideal conditions.

In its most recent incarnation, the Super AMOLED Plus features a traditional three sub-pixels of equal proportion within one pixel, along with an increased sub-pixel count and density. Both of these measures create a display that"s much more crisp, especially when it comes to text. Further, the tighter spacing between pixels results in better visibility under direct sunlight. The new Super AMOLED Plus screens are also thinner and brighter to boot.

By now, you"ve probably had the chance of viewing a glasses-free 3D screen for yourself. Whether you think the feature is cool, gimmicky or annoying -- or, all of the above -- it"s clear that autostereoscopic displays are moving into the mainstream. If you"ve ever wondered what makes this marvel possible, today is your lucky day. First, let"s start with stereoscopic imaging itself. This merely refers to a technique that creates an illusion of depth by presenting two offset images separately to the right and left eye of the viewer. Traditionally, glasses were required to complete the effect, but a creation known as the parallax barrier has done away with that. Essentially, it"s a layer of material placed atop the screen with precision slits that allows each eye to view a different set of pixels. As you"ve likely observed (or at least read about), you"re required to position the display at a very specific angle to properly view the 3D effect. Also, because the parallax barrier effectively blocks half the light emanating from the screen, the backlight is forced to shine twice as bright -- which really kills the battery. Granted, it"s an infant as technology goes, but researchers are already making refinements. For example, MIT"s HR3D is a promising project that touts better viewing angles, brightness and battery life -- largely by increasing the number and varying the orientation of the slits.

So far, we"ve discussed the underlying technologies of mobile displays, but these options are merely one factor for consideration as you select your next phone. Screen resolution is another very important topic, as it determines the amount of content that can be displayed at any given time. Many of you are likely aware of this, but the physical size of a screen conveys nothing about the content that it can display. For example, a 4.5-inch screen with an 800 x 480 resolution actually displays less information than a 3.5-inch screen with a 960 x 640 resolution. These numbers are simply measures of the physical number of pixels positioned vertically and horizontally across the screen. Taking it a step further, the 800 x 480 screen is capable of displaying 384,000 pixels worth of information, while the 960 x 640 screen is capable of displaying 614,400 pixels worth of information. Put simply, a low-res screen simply can"t convey the same amount of content as a high-res alternative.

The most common displays today are generally based around the Wide VGA (WVGA, 800 x 480) standard, and lower-res options include Half VGA (HVGA, 480 x 320) and Quarter VGA (QVGA, 320 x 240). Another variation of this is Full Wide VGA (FWVGA, 854 x 480), which is common to Motorola"s Droid family. Quarter HD (qHD) is an up-and-comer in the mobile industry, with a 960 x 540 resolution, which is one quarter the pixel count of full 1080 HD (1920 x 1080). Lest we not forget Apple"s Retina Display, which measures 960 x 640. As you"ve seen in our reviews, we"re particularly fond of high-res screens, and HVGA really is the minimum that you should accept when purchasing a new phone.

Another component of screen resolution is pixel density, which is the total number of pixels within a physical constraint. It"s calculated in pixels per inch (ppi), which is fundamentally a measure of how tightly pixels are squeezed together. This element was somewhat of an afterthought until Apple introduced the Retina Display, but it has important ramifications for the overall crispness of text and images. While the iPhone 3GS came with a 3.5-inch screen with an HVGA resolution, the iPhone 4 kept this same screen size yet boosted its resolution to 960 x 640. The result was a massive increase in pixel density, which grew from 163ppi in the iPhone 3GS to a staggering 326ppi with the iPhone 4. Of course, these numbers are merely academic until you examine the impact that a high pixel density has upon the overall legibility of small text and clarity of images. As you"d expect, other manufacturers aren"t letting Apple have all the fun in the pixel density war, and we"re seeing particularly exciting developments from Toshiba and Samsung (more on that a bit later).

If you"re interested in calculating pixel density for yourself, you"ll need to start by knowing the display size and screen resolution. From there, you"ll need to determine the diagonal resolution of the screen with a little help from our friend Pythagoras (famous for the Pythagorean theorem). For our purposes, his equation is best expressed as follows:

Now, take the diagonal resolution (in our case, 933 pixels), and divide that by the display size (4-inches). If you"ve done the math properly, you"ll see this particular display has a pixel density of 233ppi. While most smartphones on the market today feature perfectly acceptable pixel densities, this little tidbit could come in handy if you"re looking for the clearest possible display.

Now that we"ve examined display technologies and screen resolution, let"s take a brief moment to discuss touch screens, which are crucial elements for modern smartphones. The dominant touchscreen technology is known as capacitive touch, which receives feedback from your body"s ability to conduct electricity. When you place a finger on the display, the screen"s electrostatic field becomes distorted, and the change in capacitance is registered by the underlying sensor. From there, software is used to react to your input. The beautiful part about a capacitive touchscreen is its ability to register multiple points of contact at the same time, which enables multi-touch functionality such as pinch-to-zoom.

Another type of touchscreen on the market today is known as the resistive touchscreen. It"s generally less expensive to produce and responds to physical force. While there are multiple elements to a resistive screen, the most important are two electrically conductive layers that are separated by a narrow space. When you press on the display, the two layers come into contact with one another, which registers as a change in current. Unfortunately, these added layers reduce the overall brightness of the display and increase the amount of glare reflected from the screen. You"ll generally find resistive touch screens in lower-end smartphones because they don"t support multi-touch, although a few individuals appreciate its ability to receive input from a stylus, gloved fingers or fingernails.

Hopefully we"ve given you a solid overview of the current state of mobile displays, but as you"d expect in an industry that"s rapidly evolving, there"s plenty of exciting possibilities on the horizon. Here"s a few gems that are sure to whet your palate for the future.

Ortustech (a joint-venture between Casio Computer and Toppan Printing) has developed a 4.8-inch screen with full 1080p resolution and a stunning pixel density of 458ppi. While a touchscreen isn"t in the mix, manufacturers understand the appeal of full HD, and we"re seeing the industry continually advancing upon this holy grail. Likewise, Hitachi has announced a 4.5-inch IPS display with a 1280 x 720 resolution that supports glasses-free 3D to boot. Toshiba has introduced a 4-inch contender, also at 720p, with a stunning 367ppi resolution. Samsung isn"t resting on its laurels, either, and is working on mobile displays that will push between 300 and 400ppi -- by 2015, anyway. While this announcement was specifically for tablets, we know Sammy"s smartphones are bound to benefit.

Manufacturers are finding a new take on our mobile phones being a window to the world, as transparent displays are now coming into the fray. TDK began production of a see-through OLED earlier this year, and while we"d be shocked to see this novelty crop up in smartphones, it"s sure to give some added intrigue to the feature phone segment. Whether it can actually save SMS fiends from walking into oncoming traffic is still debatable.

If you find your current smartphone far too rigid, 2012 could be quite a milestone, as Samsung is readying flexible AMOLED displays for production next year. While we plan to see smartphones with large screens that can be folded into a smaller form -- a definite improvement over current hinge-based designs -- we"d love to see an outlandish solution that fully incorporates the flexible spirit.

Take one quick look at your smartphone"s power consumption and it"s painfully obvious that the display is the primary culprit. With projects such as Mirasol and E Ink Triton leading the way, we"re hoping to see a day when color "electronic ink" becomes useful for smartphones. In addition to requiring only a fraction of the power of its illuminated brethren, these displays offer full visibility in direct sunlight. Of course, the need for a light source is a given, and current refresh rates would make for lousy gaming and video playback, but these alternatives are getting better with each new announcement. For those needing maximum battery life at all costs, these displays can"t come soon enough.

Retina Display is a brand name used by Apple for its series of IPS LCD and OLED displays that have a higher pixel density than traditional Apple displays.trademark with regard to computers and mobile devices with the United States Patent and Trademark Office and Canadian Intellectual Property Office.

The Retina display debuted in 2010 with the iPhone 4 and the iPod Touch (4th Generation), and later the iPad (3rd generation) where each screen pixel of the iPhone 3GS, iPod touch (3rd generation), iPad 2 was replaced by four smaller pixels, and the user interface scaled up to fill in the extra pixels. Apple calls this mode HiDPI mode. In simpler words, it is one logical pixel = four physical pixels. The scale factor is tripled for devices with even higher pixel densities, such as the iPhone 6 Plus and iPhone X.

The Retina display has since expanded to most Apple product lines, such as Apple Watch, iPhone, iPod Touch, iPad, iPad Mini, iPad Air, iPad Pro, MacBook, MacBook Air, MacBook Pro, iMac, and Pro Display XDR, some of which have never had a comparable non-Retina display.marketing terms to differentiate between its LCD and OLED displays having various resolutions, contrast levels, color reproduction, or refresh rates. It is known as Liquid Retina display for the iPhone XR, iPad Air 4th Generation, iPad Mini 6th Generation, iPad Pro 3rd Generation and later versions,Retina 4.5K display for the iMac.

Apple"s Retina displays are not an absolute standard for display sharpness, but vary depending on the size of the display on the device, and at what distance the user would typically be viewing the screen. Where on smaller devices with smaller displays users would view the screen at a closer distance to their eyes, the displays have more PPI (Pixels Per Inch), while on larger devices with larger displays where the user views the screen further away, the screen uses a lower PPI value. Later device versions have had additional improvements, whether an increase in the screen size (the iPhone 12 Pro Max), contrast ratio (the 12.9” iPad Pro 5th Generation, and iMac with Retina 4.5K display), and/or, more recently, PPI count (OLED iPhones); as a result, Apple uses the names “Retina HD display", "Retina 4K/5K display", “Retina 4.5K display", "Super Retina HD display", “Super Retina XDR display”, and "Liquid Retina display" for each successive version.

When introducing the iPhone 4, Steve Jobs said the number of pixels needed for a Retina display is about 300 PPI for a device held 10 to 12 inches from the eye.skinny triangle with a height equal to the viewing distance and a top angle of one degree will have a base on the device"s screen that covers 57 pixels. Any display"s viewing quality (from phone displays to huge projectors) can be described with this size-independent universal parameter. Note that the PPD parameter is not an intrinsic parameter of the display itself, unlike absolute pixel resolution (e.g. 1920×1080 pixels) or relative pixel density (e.g. 401 PPI), but is dependent on the distance between the display and the eye of the person (or lens of the device) viewing the display; moving the eye closer to the display reduces the PPD, and moving away from it increases the PPD in proportion to the distance.

In practice, thus far Apple has converted a device"s display to Retina by doubling the number of pixels in each direction, quadrupling the total resolution. This increase creates a sharper interface at the same physical dimensions. The sole exception to this has been the iPhone 6 Plus, 6S Plus, 7 Plus, and 8 Plus, which renders its display at triple the number of pixels in each direction, before down-sampling to a 1080p resolution.

The displays are manufactured worldwide by different suppliers. Currently, the iPad"s display comes from Samsung,LG DisplayJapan Display Inc.twisted nematic (TN) liquid-crystal displays (LCDs) to in-plane switching (IPS) LCDs starting with the iPhone 4 models in June 2010.

Apple markets the following devices as having a Retina display, Retina HD display, Liquid Retina display, Liquid Retina XDR display, Super Retina HD display, Super Retina XDR display or Retina 4K/5K/6K display:

Reviews of Apple devices with Retina displays have generally been positive on technical grounds, with comments describing it as a considerable improvement on earlier screens and praising Apple for driving third-party application support for high-resolution displays more effectively than on Windows.T220 and T221 had been sold in the past, they had seen little take-up due to their cost of around $8400.

Writer John Gruber suggested that the arrival of Retina displays on computers would trigger a need to redesign interfaces and designs for the new displays:

The sort of rich, data-dense information design espoused by Edward Tufte can now not only be made on the computer screen but also enjoyed on one. Regarding font choices, you not only need not choose a font optimized for rendering on screen, but should not. Fonts optimized for screen rendering look cheap on the retina MacBook Pro—sometimes downright cheesy—in the same way they do when printed in a glossy magazine.

Raymond Soneira, president of DisplayMate Technologies, has challenged Apple"s claim. He says that the physiology of the human retina is such that there must be at least 477 pixels per inch in a pixelated display for the pixels to become imperceptible to the human eye at a distance of 12 inches (305 mm).Phil Plait notes, however, that, "if you have [better than 20/20] eyesight, then at one foot away the iPhone 4S"s pixels are resolved. The picture will look pixelated. If you have average eyesight [20/20 vision], the picture will look just fine... So in my opinion, what Jobs said was fine. Soneira, while technically correct, was being picky."

Apple fan website CultOfMac hosts an article by John Brownlee"Apple"s Retina Displays are only about 33% of the way there."visual acuity in the population saying "most research suggests that normal vision is actually much better than 20/20" when in truth the majority have worse than 20/20 vision,WHO considers average vision as 20/40.presbyopia

The first smartphone following the iPhone 4 to ship with a display of a comparable pixel density was the Nokia E6, running Symbian Anna, with a resolution of 640 × 480 at a screen size of 62.5mm. This was an isolated case for the platform however, as all other Symbian-based devices had larger displays with lower resolutions. Some older Symbian smartphones, including the Nokia N80 and N90, featured a 2.1 inch display at 259 ppi, which was one of the sharpest at the time. The first Android smartphones with the same display - Meizu M9 was launched a few months later in beginning of 2011. In October of the same year Galaxy Nexus was announced, which had a display with a better resolution. By 2013 the 300+ ppimark was found on midrange phones such as the Moto G.Samsung Galaxy S4 and HTC One (M8) had 1080p (FHD) screens around 5-inches for a 400+ PPI which surpassed the Retina density on the iPhone 5. The second major redesign of the iPhone, the iPhone 6, has a 1334 × 750 resolution on a 4.7-inch screen, while rivals such as the Samsung Galaxy S6 have a QHD display of 2560 × 1440 resolution, close to four times the number of pixels found in the iPhone 6, giving the S6 a 577 PPI that is almost twice that of the iPhone 6"s 326 PPI.

The larger iPhone 6 Plus features a "Retina HD display", which is a 5.5-inch 1080p screen with 401 PPI. Aside from resolution, all generations of iPhone Retina displays receive high ratings for other aspects such as brightness and color accuracy, compared to those of contemporary smartphones, while some Android devices such as the LG G3 have sacrificed screen quality and battery life for high resolution. Ars Technica suggested the "superfluousness of so many flagship phone features—the move from 720p to 1080p to 1440p and beyond...things are all nice to have, but you’d be hard-pressed to argue that any of them are essential".

Several display types are currently used in smartphones, and the most popular touchscreen displays are LCD, TFT, IPS, OLED, AMOLED, Super AMOLED and Retina.

Touchscreen LCDs fall into two categories: resistive or capacitive. Resistive touchscreens react to pressure from a finger, fingernail, stylus or other hard objects. The lack of multi-touch functionality, however, has limited resistive displays mostly to lower-end devices. Capacitive touchscreens, meanwhile, support multi-touch and are designed to react to the touch of a bare finger. This technology can be found in most mid-range to high-end smartphone and tablet displays, and users generally appreciate the smooth swiping motions and intuitive interface.

Thin Film Transistor, aka TFT LCD displays are superior to previous LCDs, delivering higher resolution and better image quality. On the other hand, TFT displays deliver poor visibility in bright light and have narrow viewing angles. This technology is typically found in budget phones or low-end smartphones.

In Plane Switching, aka IPS LCD technology delivers better viewing angles compared with TFT, while also drawing less power to allow for more battery efficiency. IPS displays typically cost more to make, however, and that"s why they"re typically used in higher-quality smartphones that come with a price to match. On the plus side, IPS is the most advanced type of LCD display tech and delivers notably wider viewing angles, extremely accurate color reproduction.

Organic Light-Emitting Diode, aka OLED displays involve a carbon-based material placed in between two conductive sheets, with class plates encasings at the top and bottom. OLED display technology delivers accurate colors, good viewing angles and a rapid response, while also allowing for lightweight and compact designs.

AMOLED, meanwhile, stands for Active-Matrix Organic Light-Emitting Diode. AMOLED and Super AMOLED technology is more expensive and is used only in high-end flagships, offering a number of benefits. This display technology delivers bright and vivid colors, great battery efficiency and wide viewing angles, while also allowing for lighter displays.

LCD and AMOLED are the most commonly used display types in current smartphones and tablets. LCDs are backlit, battery efficient, very bright, and extremely precise in displaying the entire color spectrum, which contributed to its wide popularity. AMOLED, however, eliminates the need for backlighting because each sub-pixel creates its own light. Compared to LCD, AMOLED may at times deliver less accurate colors and less visibility in direct sunlight.

Retina displays are also well-known on the market, partly because Apple is behind this technology. Apple developed and deployed Retina displays in a number of its devices, using this technology in conjunction with capacitive touchscreens. Retina displays have stirred lots of waves over the past few years due to their sharp resolution, clear and bright colors, and great accuracy.

Lastly, haptic touchscreens have their place as well on the display market. Nokia and BlackBerry have used haptic technology for some of their enterprise-oriented touchscreen smartphones and generally received positive reviews. Haptic technology basically provides tactile feedback on touch, thus confirming that it registered the touch input. Based on reviews, haptic technology can notably improve user performance and accuracy when typing on a touchscreen.

In addition to the various types of display technology, many smartphones also use Gorilla Glass protection to increase their durability. Gorilla Glass is a tough, protective glass sheet that"s highly resistant to damage. Used on many smartphones from Samsung, Motorola, Nokia and others, Gorilla Glass can provide good protection against scratches, bumps and drops, thus increasing the device"s durability.

Knowing the different types of display technology available can help users make an informed decision when purchasing a smartphone, choosing the one that best suits their needs, budgets and preferences.

Over the years, there has been a steady growth in the use of smartphones. This has led to the growth of mobile display technologies. The names such as OLED, LCD, touchscreen, retina display, have been making rounds years. AMOLED is a technology derived from OLED, and it has gained immense attention in recent years. Each of the aforementioned technologies have made a big impact owing to their distinct advantages. This post focuses on an ongoing debate on AMOLED vs LCD.

For many people, both these display technologies look the same. The following points will help you understand the basic differences between LCD and AMOLED.

Liquid Crystal Displays (LCDs) are thin-panel displays that are used in various computers, cell phones, and televisions. These displays use backlight for lighting, and they reproduce light differently than AMOLED. Thin-film transistor (TFT) and in-plane switching (IPS) are two important types of LCD displays used today.

Active-Matrix OLED (AMOLED) is a type of organic light emitting diode (OLED) display that does not require a backlight to assure power savings. These OLED display modules are commonly used for mobile phones and are emerging in the consumer tv market.

Brightness: The backlight on an LCD display helps light up pixels easily, thereby making it easier for users to read on their screens easily. Against this, AMOLED displays have low brightness levels.

Color Presentation: LCD screens are known to portray true to life colors on screen. This gives an actual idea of color to viewers who may not have seen certain things in real. However, AMOLED screens can produce vivid and bright colors with high contract ratios. AMOLED screens can produce true black colors. As no backlight is required, the display can easily power off pixels, which are required to highlight any black portions on the image. When compared, AMOLED display offers a large color gamut than other LCD displays. This is why they are available in warmer hues with a tint of red or yellow color, whereas LCD displays are blue. Yellow hues are soothing to eyes, however, blue lights will help see things in the dark. In short, AMOLED screens allow users to see vibrant colors than original, whereas LCD displays will provide real colors, thereby adding to their viewing experience.

Energy-efficient: LCD displays or screens utilize backlight for smooth operation, whereas AMOLED displays don’t require backlights. The backlight drains out battery life, and your phones may require regular recharging for proper functioning. However, AMOLED displays require no backlight, which makes them energy efficient. Also, you can use a black wallpaper to save energy on AMOLED displays.

Flexibility:AMOLED display modules are a lot more flexible among the two. Curved and circular AMOLED displays are used in many mobile phones and smart wearables. LCD displays cannot be molded or curved like AMOLED or OLED display modules, which limits their utilization in various applications.

Affordability: LCD display panels have been around for a long time, so its manufacturing has been perfected for the mobiles and other devices. Thus, mass volumes of modules can be produced at cheaper prices. However, AMOLED display module production is costlier because the technology is new, still in refinement phases. So, their manufacturing costs are higher than LCD counterparts.

As seen, each technology has its own benefits. After considering the majority of pros and cons it can be easily said that AMOLED displays are preferable than LCD panels if color presentation, battery life, and affordability are major concerns for your application. It is important that you partner with a reliable LCD or OLED display manufacturer like Microtips USA to source these modules. The company also provides custom OLED displays to meet various application

Pixel, also called Picture Element, A pixel is the smallest unit of a digital image or graphic that can be displayed and represented on a digital display device. A pixel is the basic logical unit in digital graphics. Pixels are combined to form a complete image, video, text, or any visible thing on a computer display

LCD display doesn’t operate the same way as CRT displays , which fires electrons at a glass screen, a LCD display has individual pixels arranged in a rectangular grid. Each pixel has RGB(Red, Green, Blue) sub-pixel that can be turned on or off. When all of a pixel’s sub-pixels are turned off, it appears black. When all the sub-pixels are turned on 100%, it appears white. By adjusting the individual levels of red, green, and blue light, millions of color combinations are possible

The pixels of the LCD screen were made by circuitry and electrodes of the backplane. Each sub-pixel contains a TFT (Thin Film Transistor) element.  These structures are formed by depositing various materials (metals and silicon) on to the glass substrate that will become one part of the complete display “stack,” and then making them through photolithography. For more information about TFT LCDs, please refer to “

The etched pixels by photolith process are the Native Resolution. Actually, all the flat panel displays, LCD, OLED, Plasma etc.) have native resolution which are different from CRT monitors

Although we can define a LCD display with resolution, a Full HD resolution on screen size of a 15” monitor or a 27” monitor will show different. The screen “fineness” is very important for some application, like medical, or even our cell phone. If the display “fineness” is not enough, the display will look “pixelized” which is unable to show details.

But you see other lower resolution available, that is because video cards are doing the trick. A video card can display a lower LCD screen resolution than the LCD’s built-in native resolution. The video cards can combine the pixels and turn a higher resolution into lower resolution, or just use part of the full screen. But video cards can’t do the magic to exceed the native resolution.

Special names by individual companies: Apple Macbook Pro Retina 6K display, Acer Nitro, ASUS Pro Art , ViewSonic Elite, ASUS TUF ,Samsung edge Infinity-O Display etc.

When you purchase Smartphones, you may notice after the resolution specs; the Mobile manufacturers mention the type of Display like LCD, OLED, AMOLED, sAMOLED, and Retina Display. Xiaomi, Realme, and most of the Chinese smartphone manufacturers using LCD Displays in their mid-range and Budget variants. They are using OLED displays in their flagship smartphones and Samsung using AMOLED and sAMOLED Displays. Apple uses a Retina Display. In previous days, there are only two displays available in the market, and they are called LCD and LED. That’s all. After the technology is improvising, we have to deal with a lot of terms. What are these displays? Which one is better? I try my best to explain simply in the below article. If we dive into components, it will make this guide further complicated to understand the Displays.

You may have been trying to understand the actual meaning of the different display technologies used to design smartphones these days. From an LCD screen, we moved to OLED, and now AMOLED is the bleeding-edge display used for making premium TVs and smartphones. In this article, we explained the differences between LCD, OLED, and AMOLED displays; these display technologies are unique in different aspects. Before going further in this post, you should know that LCD technology is older than OLED and AMOLED; thus, you should expect the later to come with the best features, as well as advantages.

LCD stands for Liquid Crystal Display, and it is the most common display technology used for smartphones, smart displays, some IoT devices, and televisions. The LCD technology features a unique backlight which it uses to display an image on your device screen. While you can see clearly through LCD screens, the display is reduced when compared to AMOLED. LCD Displays are probably used in Mid-range and budget Smartphones to reduce the production cost. Xiaomi uses LCD Displays to make cost-effective phones. Compare with TV LCD. Mobile LCD is not that much worse.

Advantages of LCDMost budget smartphones come with LCD because it is cheaper to affordLCDs have low flicker rates and are quite easy to disposeYou can use an LCD for any electronic gadget or device that is battery-poweredUnlike CRT displays, an LCD is not affected by magnetic fieldsLCDs can still save up battery is backlight is reduced

Disadvantages of LCDDue to backlighting, an LCD will consume more electricityDevices with an LCD tend to heat up when used some long timeWhen you view an LCD screen from different angles, the color and contrast aren’t stableImagery appear flatLCDs consume more battery

LED is what’s used to design this display technology; LED is an organic material that emits light once it receives current. Unlike LCD, We don’t need a backlight on this display. The Screen consists of a lot of small particles; when they received the current, they emit brightness and color. So, the particles that do not receive the present will always be in rest. So, that OLED Displays give more battery time compare with LCD on smartphones.

AMOLED is a type of OLED display; You can notice most of the Samsung mobiles comes with AMOLED and sAMOLED displays. However, it comes with more flexible display options. AMOLED is a step forward to OLED, and there are no many differences between the two display technologies. Well, AMOLED stands for Active Matrix Light Emitting Diode; it is the latest display technology used on most recent televisions and smartphones.

Interestingly, AMOLED poses to be the best display technology used previously. In AMOLED display tech, each LED functions individually; thus, each LED producing light for itself. Compare with regular OLED, AMOLED has TFT film instead of the glass, So, It gives more flexibility. Thus it can be used in folding phones like Samsung Galaxy Fold and Moto RAZR.

Furthermore, this display technology features a TFT chip inside; TFT stands for Thin Film Transistor; this tech helps to straighten and alleviate the process of transmitting current to the right pixel. TFT tech is one of the main reasons, while AMOLED display is used for most premium big screen devices at the moment.

Now we’ve known pretty much about LCD, OLED, and AMOLED displays; let’s discuss their features in detail, as well as compare the differences between these technologies.

Did you know? Samsung is not only a smartphone maker, but they are a component of suppliers also. Most of the other mobile manufacturers purchase displays from Samsung. Due to they are large manufacturers in this industry, they can provide a wide range of phones with the best display even in mid-range phones like “A series” and “M series.”

sAMOLED is a particular type of AMOLED that is invented by Samsung. Where there is no separate touch display. It is integrated on the top of the screen. Also, the sAMOLED screen features a wide variety of colors and color clarity.

Retina Display is a regular OLED/LCD Displays. But, To identify it is as a unique display, Apple calling its screen by this unique name. There is no difference between other types and this Retina Display. But, Apple’s best display selection and color settings make it the best display among smartphones.

Advantages of OLED/AMOLED displayOLED displays are stable when viewed from different anglesOLED and AMOLED displays are perfect for gamers because they come with faster refresh ratesThis type of screens can be used on any smartphone, irrespective of the screen sizeAMOLED is also used in making smart TVs and other premium TVs we use these daysOLED is lighter than LCD and does not use the backlighting method; instead, OLED/AMOLED used (organic/active matrix) LEDs.Both OLED and AMOLED display are verified to save more battery than LCDsAMOLED is used on slim devices because it doesn’t need a backlighting source as LCD does

Disadvantages of OLED/AMOLED displayDevices or gadgets with AMOLED/OLED display are costly because this type(s) of the screen is quite expensive to affordLCDs are brighter than OLED and AMOLEDOLED and AMOLED have shorter life-span compared to LCDVariation in colors

LCD uses a dedicated backlight from a source beneath the screen; OLED uses LED to display, while AMOLED comes with more features to add up to what OLED has to offer.

There are some advantages of using either of these display technologies on a device or television. If you have noticed, most high-end Android smartphones and Tablets come with AMOLED display instead of LCD;. However, most mid-range and low-budget smartphones come with LCD. So, that AMOLED/OLED is expensive to use on mid-range smartphones.

Other than components differences, In general, these displays have the following differences;LCD is cheaper, OLED is expensive, AMOLED, and sAMOLED is the most costly display.OLED and AMOLED tend to be battery-friendly, while LCD consumes more battery because of backlighting.Images on an LCD will be brighter than images on an OLED or AMOLED display when viewed in an outdoor environment; this is because you can increase or decrease the backlight of an LCD, but that’s not possible on OLED and AMOLED displays.LCD consists of more layers than OLED and AMOLED displays; thus, devices with AMOLED or OLED display may be slimmer/flatter than devices than LCD.AMOLED is brighter than OLED.OLED is brighter than LCD.

Best Display does not only depend on its types. The Color profile and optimization made significant parts of the best screen. That’s why Samsung Display is always brighter and has the best color differences. Many of the manufacturers try to beat Samsung, But, they have a special place in the Display industry.

The chances of buying a budget smartphone with AMOLED display are minimal; what you will likely get is an LCD. It’s not as if an LCD isn’t a good one; we are trying to show the differences between the most common screen display technologies used in making smartphones. iPhone devices come with LCD;. However, the company started using OLED from its iPhone X model, though it codenamed the screen as Super Retina and Super Retina XDR.

AMOLED display will outperform LCD; more, especially when battery and refresh rate are among the primary considerations. In general, LCDs are good, OLED is better, and AMOLED is best. When you buy new phones, you should consider this thing also.

How do you understand for example Sony"s “Triluminous Display with X-Reality”, “OptiContrast Panel” and “Mobile Bravia Engine 2” to describe the Sony Z Ultra’s display?

The smartphone industry tosses around a whole bucket of names and numbers to describe the viewing experience on your smartphone screen: ClearBlack, 1080p, Retina, AMOLED, super-sensitive..... the list goes on and on.

Some designations like flashy Apple"s Retina Display are marketing monikers cooked up to give one company an edge. Sometimes however like in case of Nokia"s Clear Black Display technology the trademarked name masks a unique process too technical to quickly explain.

Before we dive in, it"s helpful to understand the layout of a smartphone screen. The oversimplified version is that displays are composed of several layers of material, starting backing material and including a lighting element (like the backlight for LCD screens), which is then topped with a TFT (thin-film transistor) layer, which uses voltage-sipping transistors to keep the display"s pixels shining until you refresh or change the image.

I still remember the days when my phone had a narrow monochromatic screen to display a phone number. Then we started to use texts and emails, therefore we needed a bit more space to see what we"d written. Next we added the colour to give the screen a bit more interest. When we started adding cameras to the phones, we wanted the screens to be sharper, so we could see the terrible, pixelated VGA photos we"d taken.

In practice, cheap phone screens will often display dull colours, and have narrow viewing angles, which means that if you look at them from off-centre, it becomes hard to see what"s on-screen.

The LCD screens are the most common technology used on mobile phones and they range from the budget smartphones like the HTC desire C to high-end tablets, like the Google Nexus 7. Two types of LCDs are primarily found in mobile phones: TFT and IPS technology.

TFT-LCD stands for thin-film transistor - liquid crystal display and use the thin-film transistor technology to improve image quality. They are often just referred to as LCD, since TFT-based LCD screens are the only type used in practice. Each pixel on a TFT-LCD has its own transistor on the glass itself, which offers more control over the images and colors that it renders.

While TFT-LCDs can deliver sharp images, they also tend to offer relatively poor viewing angles. TFT are found on more low-end smartphones or feature phones, and on basic cell phones.

IPS stands for in-plane switching. It involves arranging and switching the molecules of the liquid crystal (LC) layer between the glass substrates. This is done in a plane parallel to these glass plates. It features two transistors for each pixel, where TFT use just one. Requires a more powerful back-light (up to 15% comparing to TFT screens) but resolves the TFT"s weaknesses related to relatively high response time (lower is better), strong viewing angle dependence and low-quality color reproduction.

IPS are more expensive in production and typically are found on high-end mobile phones and portable devices. Apple"s iPhone, iPad, HTC One X and Nokia 920 are a good example of high quality IPS-LCDs screens.

The liquid crystals do no emit light themselves, so LCDs require a backlight. That means that LCD requires more power, and could potentially be more taxing on your phone’s battery.

The LCDs however produce some of the most realistic colors you can find on a screen, but might not offer as wide of a contrast ratio (darker darks and brighter brights) as AMOLED or OLED.

The most popular type of OLED panels on mobile devices is AMOLED technology. AMOLED stands for Active Matrix Organic Light-Emitting Diode and is even more power efficient than standard OLED displays.

Due to this simple construction, AMOLED offers many advantages over LCD display
