The number of LCD (Liquid Crystal Display) panels available is vast but they can be separated into several different categories, based either on technology, construction method, or even individual brand.

Common applications can be for entertainment purposes, like watching videos and playing games, or doing technical creative work like picture editing where color accuracy is paramount.

After determining the application for your display you can start to identify which features need to take priority over others. Then you will be able to narrow your search and select the panel best suited for your use.

You get the highest performance at the lost cost. TN displays have evolved to the point where they have an incredibly fast response time, meaning they are great for entertainment purposes.

Regarding viewing angle, the TN display suffers particularly in the vertical direction; when watching a movie you must be sitting directly in front of the display to get the best picture.

Most TN displays can represent only 70% of NTSC, Adobe RGB and sRGB color gamuts, in some cases as little as 10 to 30% with the poorest quality displays.

When it comes to choosing a display for a creative application it is important to consider only a high-quality TN display as the color gamut will be higher.

The viewing angle in specific IPS screens has improved to the point where crystal-clear viewing is possible at 178 of the 180 degrees available to a user.

Contrast and blacks have also considerably improved. IPS panels do not lighten or show tailing light when touched, which can happen on TN panels; this is important for touch-screen devices such as smartphones and tablets.

However, as with all new technology, it is not perfect. The response times of IPS panels still falls behind those of TN technology. The cost of an IPS panel is also higher than that of a TN panel.

In market, LCD means passive matrix LCDs which increase TN (Twisted Nematic), STN (Super Twisted Nematic), or FSTN (Film Compensated STN) LCD Displays. It is a kind of earliest and lowest cost display technology.

LCD screens are still found in the market of low cost watches, calculators, clocks, utility meters etc. because of its advantages of low cost, fast response time (speed), wide temperature range,  low power consumption, sunlight readable with transflective or reflective polarizers etc.  Most of them are monochrome LCD display and belong to passive-matrix LCDs.

TFT LCDs have capacitors and transistors. These are the two elements that play a key part in ensuring that the TFT display monitor functions by using a very small amount of energy without running out of operation.

Normally, we say TFT LCD panels or TFT screens, we mean they are TN (Twisted Nematic) Type TFT displays or TN panels, or TN screen technology. TFT is active-matrix LCDs, it is a kind of LCD technologies.

TFT has wider viewing angles, better contrast ratio than TN displays. TFT display technologies have been widely used for computer monitors, laptops, medical monitors, industrial monitors, ATM, point of sales etc.

Actually, IPS technology is a kind of TFT display with thin film transistors for individual pixels. But IPS displays have superior high contrast, wide viewing angle, color reproduction, image quality etc. IPS screens have been found in high-end applications, like Apple iPhones, iPads, Samsung mobile phones, more expensive LCD monitors etc.

Both TFT LCD displays and IPS LCD displays are active matrix displays, neither of them can produce color, there is a layer of RGB (red, green, blue) color filter in each LCD pixels to make LCD showing colors. If you use a magnifier to see your monitor, you will see RGB color. With switch on/off and different level of brightness RGB, we can get many colors.

Neither of them can’t release color themselves, they have relied on extra light source in order to display. LED backlights are usually be together with them in the display modules as the light sources. Besides, both TFT screens and IPS screens are transmissive, it will need more power or more expensive than passive matrix LCD screens to be seen under sunlight.  IPS screens transmittance is lower than TFT screens, more power is needed for IPS LCD display.

If you want to buy a new monitor, you might wonder what kind of display technologies I should choose. In today’s market, there are two main types of computer monitors: TFT LCD monitors & IPS monitors.

The word TFT means Thin Film Transistor. It is the technology that is used in LCD displays.  We have additional resources if you would like to learn more about what is a TFT Display. This type of LCDs is also categorically referred to as an active-matrix LCD.

These LCDs can hold back some pixels while using other pixels so the LCD screen will be using a very minimum amount of energy to function (to modify the liquid crystal molecules between two electrodes). TFT LCDs have capacitors and transistors. These two elements play a key part in ensuring that the TFT display monitor functions by using a very small amount of energy while still generating vibrant, consistent images.

Industry nomenclature: TFT LCD panels or TFT screens can also be referred to as TN (Twisted Nematic) Type TFT displays or TN panels, or TN screen technology.

IPS (in-plane-switching) technology is like an improvement on the traditional TFT LCD display module in the sense that it has the same basic structure, but has more enhanced features and more widespread usability.

These LCD screens offer vibrant color, high contrast, and clear images at wide viewing angles. At a premium price. This technology is often used in high definition screens such as in gaming or entertainment.

Both TFT display and IPS display are active-matrix displays, neither can’t emit light on their own like OLED displays and have to be used with a back-light of white bright light to generate the picture. Newer panels utilize LED backlight (light-emitting diodes) to generate their light hence utilizing less power and requiring less depth by design. Neither TFT display nor IPS display can produce color, there is a layer of RGB (red, green, blue) color filter in each LCD pixels to produce the color consumers see. If you use a magnifier to inspect your monitor, you will see RGB color in each pixel. With an on/off switch and different level of brightness RGB, we can get many colors.

Winner. IPS TFT screens have around 0.3 milliseconds response time while TN TFT screens responds around 10 milliseconds which makes the latter unsuitable for gaming

Winner. the images that IPS displays create are much more pristine and original than that of the TFT screen. IPS displays do this by making the pixels function in a parallel way. Because of such placing, the pixels can reflect light in a better way, and because of that, you get a better image within the display.

As the display screen made with IPS technology is mostly wide-set, it ensures that the aspect ratio of the screen would be wider. This ensures better visibility and a more realistic viewing experience with a stable effect.

Winner. While the TFT LCD has around 15% more power consumption vs IPS LCD, IPS has a lower transmittance which forces IPS displays to consume more power via backlights. TFT LCD helps battery life.

Normally, high-end products, such as Apple Mac computer monitors and Samsung mobile phones, generally use IPS panels. Some high-end TV and mobile phones even use AMOLED (Active Matrix Organic Light Emitting Diodes) displays. This cutting edge technology provides even better color reproduction, clear image quality, better color gamut, less power consumption when compared to LCD technology.

What you need to choose is AMOLED for your TV and mobile phones instead of PMOLED. If you have budget leftover, you can also add touch screen functionality as most of the touch nowadays uses PCAP (Projective Capacitive) touch panel.

This kind of touch technology was first introduced by Steve Jobs in the first-generation iPhone. Of course, a TFT LCD display can always meet the basic needs at the most efficient price. An IPS display can make your monitor standing out.

If you’ve ever begun searching for a new computer screen, chances are you’ve probably come across the term IPS. It’s at this point that you may be asking yourself, what is an IPS monitor? And how do I know if an IPS monitor is right for me?

So, why is this important? A monitor’s panel technology is important because it affects what the monitor can do and for which uses it is best suited. Each of the monitor panel types listed above offer their own distinctive benefits and drawbacks.

Choosing which type of monitor panel type to buy will depend largely on your intended usage and personal preference. After all, gamers, graphic designers, and office workers all have different requirements. Specific types of displays are best suited for different usage scenarios.

The reason for this is because none of the different monitor panel types as they are today can be classified as “outstanding” for all of the attributes mentioned above.

Below we’ll take a look at how IPS, TN, and VA monitors affect screen performance and do some handy summaries of strengths, weaknesses, and best-case uses for each type of panel technology.

IPS monitors or “In-Plane Switching” monitors, leverage liquid crystals aligned in parallel to produce rich colors. IPS panels are defined by the shifting patterns of their liquid crystals. These monitors were designed to overcome the limitations of TN panels. The liquid crystal’s ability to shift horizontally creates better viewing angles.

IPS monitors continue to be the display technology of choice for users that want color accuracy and consistency. IPS monitors are really great when it comes to color performance and super-wide viewing angles. The expansive viewing angles provided by IPS monitors help to deliver outstanding color when being viewed from different angles. One major differentiator between IPS monitors and TN monitors is that colors on an IPS monitor won’t shift when being viewed at an angle as drastically as they do on a TN monitor.

IPS monitor variations include S-IPS, H-IPS, e-IPS and P-IPS, and PLS (Plane-to-Line Switching), the latter being the latest iteration. Since these variations are all quite similar, they are all collectively referred to as “IPS-type” panels. They all claim to deliver the major benefits associated with IPS monitors – great color and ultra-wide viewing angles.

When it comes to color accuracy, IPS monitors surpass the performance of TN and VA monitors with ease. While latest-gen VA technologies offer comparative performance specs, pro users still claim that IPS monitors reign supreme in this regard.

Another important characteristic of IPS monitors is that they are able to support professional color space technologies, such as Adobe RGB. This is due to the fact that IPS monitors are able to offer more displayable colors, which help improve color accuracy.

In the past, response time and contrast were the initial weakness of IPS technology. Nowadays, however, IPS monitor response times have advanced to the point where they are even capable of satisfying gamers, thus resulting in a rising popularity in IPS monitors for gaming.

With regard to gaming, some criticisms IPS monitors include more visible motion blur coming as a result of slower response times, however the impact of motion blur will vary from user to user. In fact, mixed opinions about the “drawbacks” of IPS monitor for gaming can be found all across the web. Take this excerpt from one gaming technology writer for example: “As for pixel response, opinions vary. I personally think IPS panels are quick enough for almost all gaming. If your gaming life is absolutely and exclusively about hair-trigger shooters, OK, you’ll want the fastest response, lowest latency LCD monitor. And that means TN. For the rest of us, and certainly for those who place even a modicum of importance on the visual spectacle of games, I reckon IPS is clearly the best panel technology.” Read the full article here.

IPS monitors deliver ultra-wide 178-degree vertical and horizontal viewing angles. Graphic designers, CAD engineers, pro photographers, and video editors will benefit from using an IPS monitor. Many value the color benefits of IPS monitors and tech advances have improved IPS panel speed, contrast, and resolution. IPS monitors are more attractive than ever for general desktop work as well as many types of gaming. They’re even versatile enough to be used in different monitor styles, so if you’ve ever compared an ultrawide vs. dual monitor setup or considered the benefits of curved vs. flat monitors, chances are you’ve already come into contact with an IPS panel.

TN monitors, or “Twisted Nematic” monitors, are the oldest LCD panel types around. TN panels cost less than their IPS and VA counterparts and are a popular mainstream display technology for desktop and laptop displays.

Despite their lower perceived value, TN-based displays are the panel type preferred by competitive gamers. The reason for this is because TN panels can achieve a rapid response time and the fastest refresh rates on the market (like this 240Hz eSports monitor). To this effect, TN monitors are able to reduce blurring and screen tearing in fast-paced games when compared to an IPS or VA panel.

On the flip side, however, TN panel technology tends to be ill-suited for applications that benefit from wider viewing angles, higher contrast ratios, and better color accuracy. That being said, LED technology has helped shift the perspective and today’s LED-backlit TN models offer higher brightness along with better blacks and higher contrast ratios.

Today’s maximum possible viewing angles are 178 degrees both horizontally and vertically (178º/178º), yet TN panels are limited to viewing angles of approximately 170 degrees horizontal and 160 degrees vertical (170º /160º).

In fact, TN monitor can sometimes be easily identified by the color distortion and contrast shifting that’s visible at the edges of the screen. As screen sizes increase, this issue becomes even more apparent as reduced color performance can even begin to be seen when viewing the screen from a dead-center position.

For general-purpose use, these shifts in color and contrast are often irrelevant and fade from conscious perception. However, this color variability makes TN monitors a poor choice for color-critical work like graphic design and photo editing. Graphic designers and other color-conscious users should also avoid TN displays due to their more limited range of color display compared to the other technologies.

TN monitors are the least expensive panel technology, making them ideal for cost-conscious businesses and consumers. In addition, TN monitors enjoy unmatched popularity with competitive gamers and other users who seek rapid graphics display.

Vertical alignment (VA) panel technology was developed to improve upon the drawbacks of TN. Current VA-based monitors offer muchhigher contrast, better color reproduction, and wider viewing angles than TN panels. Variations you may see include P-MVA, S-MVA, and AMVA (Advanced MVA).

These high-end VA-type monitors rival IPS monitors as the best panel technology for professional-level color-critical applications. One of the standout features of VA technology is that it is particularly good at blocking light from the backlight when it’s not needed. This enables VA panels to display deeper blacks and static contrast ratios of up to several times higher than the other LCD technologies. The benefit of this is that VA monitors with high contrast ratios can deliver intense blacks and richer colors.

Contrast ratio is the measured difference between the darkest blacks and the brightest whites a monitor can produce. This measurement provides information about the amount of grayscale detail a monitor will deliver. The higher the contrast ratio, the more visible detail.

These monitors also provide more visible details in shadows and highlights, making them ideal for enjoying videos and movies. They’re also a good fit for games focused on rich imagery (RPG games for example) rather than rapid speed (such as FPS games).

MVA and other recent VA technologies offer the highest static contrast ratios of any panel technology. This allows for an outstanding visual experience for movie enthusiasts and other users seeking depth of detail. Higher-end, feature-rich MVA displays offer the consistent, authentic color representation needed by graphic designers and other pro users.

There is another type of panel technology that differs from the monitor types discussed above and that is OLED or “Organic Light Emitting Diode” technology. OLEDs differ from LCDs because they use positively/negatively charged ions to light up every pixel individually, while LCDs use a backlight, which can create an unwanted glow. OLEDs avoid screen glow (and create darker blacks) by not using a backlight. One of the drawbacks of OLED technology is that it is usually pricier than any of the other types of technology explained.

When it comes to choosing the right LCD panel technology, there is no single right answer. Each of the three primary technologies offers distinct strengths and weaknesses. Looking at different features and specs helps you identify which monitor best fits your needs.

With the lowest cost and fastest response times, TN monitors are great for general use and gaming. VA monitor offers a step up for general use. Maxed-out viewing angles and high contrast ratios make VA monitors great for watching movies and image-intensive gaming.

IPS monitors offer the greatest range of color-related features and remain the gold standard for photo editing and color-critical pro uses. Greater availability and lower prices make IPS monitors a great fit for anyone who values outstanding image quality.

LCD or “Liquid Crystal Display” is a type of monitor panel that embraces thin layers of liquid crystals sandwiched between two layers of filters and electrodes.

While CRT monitors used to fire electrons against glass surfaces, LCD monitors operate using backlights and liquid crystals. The LCD panel is a flat sheet of material that contains layers of filters, glass, electrodes, liquid crystals, and a backlight. Polarized light (meaning only half of it shines through) is directed towards a rectangular grid of liquid crystals and beamed through.

Liquid Crystals (LCs) are used because of their unique ability to maintain a parallel shape. Acting as both a solid and liquid, LCs are able to react quickly to changes in light patterns. The optical properties of LCs are activated by electric current, which is used to switch liquid crystals between phases. In turn, each pixel generates an RGB (red, green, blue) color based on the phase it’s in.

Note: When searching for monitors you can be sure to come across the term “LED Panel” at some point or another. An LED panel is an LCD screen with an LED – (Light Emitting Diode) – backlight. LEDs provide a brighter light source while using much less energy. They also have the ability to produce white color, in addition to traditional RGB color, and are the panel type used in HDR monitors.

Early LCD panels used passive-matrix technology and were criticized for blurry imagery. The reason for this is because quick image changes require liquid crystals to change phase quickly and passive matrix technology was limited in terms of how quickly liquid crystals could change phase.

As a result, active-matrix technology was invented and transistors (TFTs) began being used to help liquid crystals retain their charge and change phase more quickly.

Thanks to active-matrix technology, LCD monitor panels were able to change images very quickly and the technology began being used by newer LCD panels.

Ultimately, budget and feature preferences will determine the best fit for each user. Among the available monitors of each panel type there will also be a range of price points and feature sets. Additionally, overall quality may vary among manufacturers due to factors related to a display’s components, manufacturing, and design.

If you’re interested in learning more about IPS monitors, you can take a look at some of these professional monitors to see if they would be the right fit for you.

Alternatively, if you’re into gaming and are in the market for TN panel these gaming monitor options may be along the lines of what you’re looking for.

Before you get a new monition for your organization, comparing the TFT display vs IPS display is something that you should do. You would want to buy the monitor which is the most advanced in technology. Therefore, understanding which technology is good for your organization is a must. click to view the 7 Best Types Of Display Screens Technology.

Technology is changing and becoming advanced day by day. Therefore, when you are looking to get a new monitor for your organization, LCD advantages, and disadvantage,  you have to be aware of the pros and cons of that monitor. Moreover, you need to understand the type of monitor you are looking to buy.

Now, understanding the technology from the perspective of a tech-savvy person may not be the ideal thing to do unless you are that tech-savvy person. If you struggle to understand technology, then understanding it in a layman’s language would be the ideal thing to do.

That is why it is important to break it down and discuss point by point so that you can understand it in a layman’s language devoid of any technical jargon. Therefore, in this very article, let’s discuss what exactly TFT LCDs and IPS LCDs are, and what are their differences? You will also find out about their pros and cons for your organization.

The word TFT means Thin-Film-Translator. Click to view: what is TFT LCD,  It is the technology that is used in LCD or Liquid Crystal Display. Here you should know that this type of LCD is also categorically referred to as active-matrix LCDs. It tells that these LCDs can hold back some pixels while using other pixels. So, the LCD will be using a very minimum amount of energy to function. TFT LCDs have capacitors and transistors. These are the two elements that play a key part in ensuring that the display monitor functions by using a very small amount of energy without running out of operation.

The display range covers the application range of all displays from 1 inch to 40 inches as well as the large projection plane and is a full-size display terminal.

Display quality from the simplest monochrome character graphics to high resolution, high color fidelity, high brightness, high contrast, the high response speed of a variety of specifications of the video display models.

No radiation, no scintillation, no harm to the user’s health. In particular, the emergence of TFT LCD electronic books and periodicals will bring humans into the era of a paperless office and paperless printing, triggering a revolution in the civilized way of human learning, dissemination, and recording.

It can be normally used in the temperature range from -20℃ to +50℃, and the temperature-hardened TFT LCD can operate at low temperatures up to -80 ℃. It can not only be used as a mobile terminal display, or desktop terminal display but also can be used as a large screen projection TV, which is a full-size video display terminal with excellent performance.

The manufacturing technology has a high degree of automation and good characteristics of large-scale industrial production. TFT LCD industry technology is mature, a mass production rate of more than 90%.

It is a perfect combination of large-scale semiconductor integrated circuit technology and light source technology and has great potential for further development.

TFT LCD screen from the beginning of the use of flat glass plate, its display effect is flat right angles, let a person have a refreshing feeling. And LCDs are easier to achieve high resolution on small screens.

The word IPS refers to In-Plane-Switching which is a technology used to improve the viewing experience of the usual TFT displays. You can say that the IPS display is a more advanced version of the traditional TFT LCD module. However, the features of IPS displays are much more advanced and their applications are very much widespread. You should also know that the basic structure of the IPS LCD is the same as TFT LCD if you compare TFT LCD vs IPS.

As you already know, TFT displays do have a very quick response time which is a plus point for it. But, that does not mean IPS displays a lack of response time. In fact, the response time of an IPS LCD is much more consistent, stable, and quick than the TFT display that everyone used to use in the past. However, you will not be able to gauge the difference apparently by watching TFT and IPS displays separately. But, once you watch the screen side-by-side, the difference will become quite clear to you.

The main drawback of the TFT displays as figured above is the narrow-angle viewing experience. The monitor you buy for your organization should give you an experience of wide-angle viewing. It is very much true if you have to use the screen by staying in motion.

So, as IPS displays are an improved version of TFT displays the viewing angle of IPS LCDs is very much wide. It is a plus point in favor of IPS LCDs when you compare TFT vs IPS. With a TFT screen, you cannot watch an image from various angles without encountering halo effects, blurriness, or grayscale that will cause problems for your viewing.

It is one of the major and remarkable differences between IPS and TFT displays. So, if you don’t want to comprise on the viewing angles and want to have the best experience of viewing the screen from wide angles, the IPS display is what you want. The main reason for such a versatile and wonderful viewing angle of IPS display is the screen configuration which is widely set.

Now, when you want to achieve wide-angle viewing with your display screen, you need to make sure it has a faster level of frequency transmittance. It is where IPS displays overtake TFT displays easily in the comparison because the IPS displays have a much faster and speedier transmittance of frequencies than the TFT displays.

Now the transmittance difference between TFT displays and IPS displays would be around 1ms vs. 25ms. Now, you might think that the difference in milliseconds should not create much of a difference as far as the viewing experience is concerned. Yes, this difference cannot be gauged with a naked eye and you will find it difficult to decipher the difference.

However, when you view and an IPS display from a side-by-side angle and a TFT display from a similar angle, the difference will be quite evident in front of you. That is why those who want to avoid lagging in the screen during information sharing at a high speed; generally go for IPS displays. So, if you are someone who is looking to perform advanced applications on the monitor and want to have a wider viewing angle, then an IPS display is the perfect choice for you.

As you know, the basic structure of the IPS display and TFT displays are the same. So, it is quite obvious that an IPS display would use the same basic colors to create various shades with the pixels. However, there is a big difference with the way a TFT display would produce the colors and shade to an IPS display.

The major difference is in the way pixels get placed and the way they operate with electrodes. If you take the perspective of the TFT display, its pixels function perpendicularly once the pixels get activated with the help of the electrodes. It does help in creating sharp images.

But the images that IPS displays create are much more pristine and original than that of the TFT screen. IPS displays do this by making the pixels function in a parallel way. Because of such placing, the pixels can reflect light in a better way, and because of that, you get a better image within the display.

As the display screen made with IPS technology is mostly wide-set, it ensures that the aspect ratio of the screen would be wider. This ensures better visibility and a more realistic viewing experience with a stable effect.

As you already know the features of both TFT and IPS displays, it would be easier for you to understand the difference between the two screen-types. Now, let’s divide the matters into three sections and try to understand the basic differences so that you understand the two technologies in a compressive way. So, here are the difference between an IPS display and a TFT display;

Now, before starting the comparison, it is quite fair to say that both IPS and TFT displays have a wonderful and clear color display. You just cannot say that any of these two displays lag significantly when it comes to color clarity.

However, when it comes to choosing the better display on the parameter of clarity of color, then it has to be the IPS display. The reason why IPS displays tend to have better clarity of color than TFT displays is a better crystal oriental arrangement which is an important part.

That is why when you compare the IPS LCD with TFT LCD for the clarity of color, IPS LCD will get the nod because of the better and advanced technology and structure.

IPS displays have a wider aspect ratio because of the wide-set configuration. That is why it will give you a better wide-angle view when it comes to comparison between IPS and TFT displays. After a certain angle, with a TFT display, the colors will start to get a bit distorted.

But, this distortion of color is very much limited in an IPS display and you may see it very seldom after a much wider angle than the TFT displays. That is why for wide-angle viewing, TFT displays will be more preferable.

When you are comparing TFT LCD vs. IPS, energy consumption also becomes an important part of that comparison. Now, IPS technology is a much advanced technology than TFT technology. So, it is quite obvious that IPS takes a bit more energy to function than TFT.

Also, when you are using an IPS monitor, the screen will be much larger. So, as there is a need for much more energy for the IPS display to function, the battery of the device will drain faster. Furthermore, IPS panels cost way more than TFT display panels.

2. When it comes to visibility, the TFT technology enhances your experience wonderfully. It creates sharp images that will have no problems for older and tired eyes.

Although IPS screen technology is very good, it is still a technology based on TFT, the essence of the TFT screen. Whatever the strength of the IPS, it is a TFT-based derivative.

Finally, as you now have a proper understanding of the TFT displays vs IPS displays, it is now easier for you when it comes to choose one for your organization. Technology is advancing at a rapid pace. You should not be surprised if you see more advanced display screens in the near future. However, so far, TFT vs IPS are the two technologies that are marching ahead when it comes to making display screens.

IPS (in-plane switching) is a screen technology for liquid-crystal displays (LCDs). In IPS, a layer of liquid crystals is sandwiched between two glass surfaces. The liquid crystal molecules are aligned parallel to those surfaces in predetermined directions (in-plane). The molecules are reoriented by an applied electric field, whilst remaining essentially parallel to the surfaces to produce an image. It was designed to solve the strong viewing angle dependence and low-quality color reproduction of the twisted nematic field effect (TN) matrix LCDs prevalent in the late 1980s.

The TN method was the only viable technology for active matrix TFT LCDs in the late 1980s and early 1990s. Early panels showed grayscale inversion from up to down,Vertical Alignment (VA)—that could resolve these weaknesses and were applied to large computer monitor panels.

After thorough analysis, details of advantageous molecular arrangements were filed in Germany by Guenter Baur et al. and patented in various countries including the US on 9 January 1990.Fraunhofer Society in Freiburg, where the inventors worked, assigned these patents to Merck KGaA, Darmstadt, Germany.

Shortly thereafter, Hitachi of Japan filed patents to improve this technology. A leader in this field was Katsumi Kondo, who worked at the Hitachi Research Center.thin-film transistor array as a matrix and to avoid undesirable stray fields in between pixels.Super IPS). NEC and Hitachi became early manufacturers of active-matrix addressed LCDs based on the IPS technology. This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and in-plane switching subsequently remain the dominant LCD designs through 2006.

IPS technology is widely used in panels for TVs, tablet computers, and smartphones. In particular, most IBM products was marketed as CCFL backlighting, and all Apple Inc. products marketed with the label backlighting since 2010.

Most panels also support true 8-bit-per-channel colour. These improvements came at the cost of a lower response time, initially about 50 ms. IPS panels were also extremely expensive.

IPS has since been superseded by S-IPS (Super-IPS, Hitachi Ltd. in 1998), which has all the benefits of IPS technology with the addition of improved pixel refresh timing.

In this case, both linear polarizing filters P and A have their axes of transmission in the same direction. To obtain the 90 degree twisted nematic structure of the LC layer between the two glass plates without an applied electric field (OFF state), the inner surfaces of the glass plates are treated to align the bordering LC molecules at a right angle. This molecular structure is practically the same as in TN LCDs. However, the arrangement of the electrodes e1 and e2 is different. Because they are in the same plane and on a single glass plate, they generate an electric field essentially parallel to this plate. The diagram is not to scale: the LC layer is only a few micrometers thick and so is very small compared with the distance between the electrodes.

The LC molecules have a positive dielectric anisotropy and align themselves with their long axis parallel to an applied electrical field. In the OFF state (shown on the left), entering light L1 becomes linearly polarized by polarizer P. The twisted nematic LC layer rotates the polarization axis of the passing light by 90 degrees, so that ideally no light passes through polarizer A. In the ON state, a sufficient voltage is applied between electrodes and a corresponding electrical field E is generated that realigns the LC molecules as shown on the right of the diagram. Here, light L2 can pass through polarizer A.

In practice, other schemes of implementation exist with a different structure of the LC molecules – for example without any twist in the OFF state. As both electrodes are on the same substrate, they take more space than TN matrix electrodes. This also reduces contrast and brightness.

Unlike TN LCDs, IPS panels do not lighten or show tailing when touched. This is important for touch-screen devices, such as smartphones and tablet computer.s

Toward the end of 2010 Samsung Electronics introduced Super PLS (Plane-to-Line Switching) with the intent of providing an alternative to the popular IPS technology which is primarily manufactured by LG Display. It is an "IPS-type" panel technology, and is very similar in performance features, specs and characteristics to LG Display"s offering. Samsung adopted PLS panels instead of AMOLED panels, because in the past AMOLED panels had difficulties in realizing full HD resolution on mobile devices. PLS technology was Samsung"s wide-viewing angle LCD technology, similar to LG Display"s IPS technology.

In 2012 AU Optronics began investment in their own IPS-type technology, dubbed AHVA. This should not be confused with their long standing AMVA technology (which is a VA-type technology). Performance and specs remained very similar to LG Display"s IPS and Samsung"s PLS offerings. The first 144 Hz compatible IPS-type panels were produced in late 2014 (used first in early 2015) by AUO, beating Samsung and LG Display to providing high refresh rate IPS-type panels.

Cutting edge display technology has been a central feature of flagship smartphones in recent years. The LG V30 arrived late last year with yet another innovation in screen tech: new panel type called P-OLED. With Samsung still marketing its Super AMOLED and Infinity Display technology, and some other manufacturers moving away from the tried and tested IPS LCD, there’s never been more choice for display panel tech in the smartphone market.

P-OLED isn’t exactly the new kid on the block, but the technology is just starting to appear in a number of flagship handsets. We’ve already seen how LG Display’s P-OLED stacks up against Samsung’s AMOLED,but what about the common IPS LCD display technology? That’s what we aim to find out in this P-OLED vs IPS LCD breakdown.

The common LCD stands for Liquid Crystal Display, while IPS stands for “in-plane switching”. The latter controlls the crystal elements in the display’s RGB sub-pixel layout. IPS replaced twisted nematic field effect (TN) as the technology of choice for LCD in the 90s, and is what you’ll find in all LCD-based smartphone panels.

The technology features a polarized backlight passing through the liquid crystals, in front of red, green, and blue color filters for each sub-pixel. With IPS, a current is used to create an electric field parallel to the plate, which twists the polarized crystal and further shifts the polarity of the light. A second polarizer then filters out the light based on its polarity. The more light passes through the second polarizer, the brighter the associated RGB sub-pixel will be.

Each sub-pixel is connected up to a thin-film transistor active matrix, which drives the panel’s brightness and color without consuming as much current as an outdated passive matrix display. Using different TFT materials and production techniques can alter the driving properties of the display and alter the transistor sizes, which affects properties such as brightness, viewing angles, and color gamut. Hence why you’ll find a variety of different naming schemes for IPS LCD display, including Super IPS, Super LCD5, and others.

The makeup of the backlight can vary between LCD panels too, as the white light has to be created from another group of colors. The light source can be made up of LEDs or an electroluminescent panel (ELP), among others, each of which can offer a slightly different white tint and varying degrees of even light across their surface.

Pixels can suffer from lower aperture at higher resolutions, as transistor sizes can’t be shrunk further, reducing peak brightness and wasting energy.

OLED technology has been the major rival to LCD in the smartphone market for what seems like forever. Samsung’s AMOLED technology has powered generations of the top selling Android flagship. Plastic-OLED (or P-OLED) is simply the latest iteration of this technology, primarily designed to enable new and interesting form factors.

Compared with the numerous layers of an LCD display, P-OLED is considerably less complicated looking. The key component is a Light Emitting Diode (LED). So rather than relying on a universal backlight, each sub-pixel is capable of producing its own red, green, or blue light, or being shut-off completely. The O part in OLED stands for organic, which is the compound type that lights up when current is applied.

To drive this current, the TFT matrix is used in a very similar way to LCD. Although this time the current is used to produce the light rather than twist the polarizing crystals. As this is an active matrix TFT, Samsung chose to call its OLED panels AMOLED. P-OLED shouldn’t be confused with the outdated PMOLED technology, which stands for passive matrix and isn’t used in any modern pieces of high-end display tech.

So where does the plastic element come in? Well it’s simply the material used as the back substrate on which the TFT and OLED components are placed. Historically, this has been made from glass but using a plastic substrate makes the display more malleable and flexible. It’s important to note however, that switching over to a plastic substrate requires new materials for the TFT plane that can withstand the manufacturing temperatures, while still providing sufficient electron mobility and current for the LEDs.

The two display technologies have their own pros and cons in terms of viewing quality, but plastic OLED has a trick up its sleeve that LCD can’t yet match — flexibility.

LG recently stated that its move to P-OLED in the V30 smartphone wasn’t based on increased image quality. Instead, the company acknowledged that thin bezels and curved designs are in high demand from consumers. The only currently viable way to achieve these designs is by using a flexible plastic substrate in an OLED display, which makes the panel lighter, thinner, and more pliable than using a traditional glass substrate.

While the aesthetics won’t be to everyone’s tastes, manufacturers are clearly interested in plastic OLED as a way to help differentiate their smartphones from the competitors. Although this effect will diminish as more and more manufacturers move over to a similar looking, slim bezel design. For us consumers, another added benefit from the move to P-OLED is more durable displays.

Although the very top of a smartphone display will likely feature a protective glass layer, such as Gorilla Glass, the underlying plastic substrate layer does offer some additional shock absorption. This means that it’s less likely that the TFT layer will break on dropping, helping to preserve functionality even if the top layer cracks.

It’s worth stating that flexible LCD alternatives are in development. Japan Display showcased its low-cost flexible LCD technology in early 2017 and other companies are working on Organic LCD and similar ideas. However, the trick is still to match flexible OLED for pixel density and resolution, color gamut, and production yield. So it’s likely to be a while before we see competing flexible LCD products.

Unfortunately, there’s no definitive superior technology between IPS LCD and P-OLED. There are too many variables beyond the basic display type that determine the quality of the viewing experience. These include sub-pixel layouts and manufacturing materials.

No two IPS LCD manufacturers are necessarily alike, and even P-OLED will undoubtedly go through generational revisions over the next few years and continue to improve performance. Furthermore, new advances in LCD technology, including Quantum Dot, WRGB, and others, keep  reinvigorating the already well-refined technology.

Where OLED, including Plastic-OLED, does have a notable head start is in the growing demand for HDR and virtual reality applications. There, deep contrast and very high panel refresh rates in compact form factors are the order of the day. Combined with the more unique form factors available in smartphones and automotive and industrial applications, we’re bound to see plenty more P-OLED in the coming years.

• Set up, feed and operate screen presses efficiently referencing blueprints and job jackets, while maintaining high quality and performance standards.

• Dexterity and Arm-Hand Steadiness – ability to quickly move hands, arms, fingers to grasp, manipulate or assemble and the ability to keep hand and arm steady.

Both screens are made up of Pixels. A pixel is made up of 3 sections called sub-pixels. The three sections are red, green and blue (primary colors for display tech).

The light is generated from a “backlight”. A series of thin films, transparent mirrors and an array of white LED Lights that shine and distribute light across the back of the display.

On some lower quality LCD screens, you can see bright spots in the middle or on the perimeters of screens. This is caused by uneven light distribution. The downside to using backlights, is that black is never true black, because no matter what, light has to be coming through, so it will never have as dark of a screen as an AMOLED screen. Its comparable to being able to slow a car down to 2 mph versus coming to a complete stop.

Each pixel is its own light source, meaning that no backlight is necessary. This allows the screen assembly to be thinner, and have more consistent lighting across the whole display.

IPS screen has the advantages of high visual angle, fast response and accurate color restoration, so it is a high-end product in LCD panel. Compared with other types of panels, IPS screen panels are not prone to water pattern deformation by gently scratching with their hands, so they are also known as hard screens. When you look at the screen carefully, if you see the fish scale pixels facing left, plus the hard screen, then you can determine that it is the IPS screen.

IPS LCD panel not only has certain advantages in durability and easy cleaning, but also leads VA soft screen in terms of functional parameters and performance indicators. Response time has always been the deficiency of LCD TV, but with the continuous progress of LCD technology, the problem of picture trailing of LCD TV has been well solved on the IPS panel. The advantage of short response time enables the IPS screen to show a clearer image in the dynamic picture. In addition, compared with the VA soft screen, the IPS screen has the advantages of accurate color restoration and outstanding black expression.

Technical experts said that IPS hard-screen LCD TV can excellent performance of dynamic high-definition pictures, especially suitable for motion image reproduction, no residual shadow and trailing, and is an ideal carrier for watching digital high-definition images, especially fast motion pictures, such as competitions, speed games and action movies. Experts also said that because of the unique horizontal molecular structure of the IPS screen, it is very stable without water lines, shadows and flashes when touching, so it is extremely suitable for televisions and public display devices with touch functions.

IPS stands for “in-plane switching”. In the context of digital industrial displays, this means that this technology essentially uses liquid crystals that are perfectly aligned in a parallel pattern with the capability to produce vibrant colours and colour contrast on screen.

Users that require total colour accuracy, consistency, and vibrancy such as photographers, videographers, graphic designers, and gamers will appreciate the sophistication of IPS display technology.

A notable feature of IPS LCD monitors is that they provide an incredibly expansive viewing angle which works to fully showcase vivid colours on every end of the spectrum in ways that other LCD monitors can’t.

There are a number of different factors you should take into consideration when selecting an IPS display monitor for your personal or professional use.

Screen size impacts the pixel density of images and videos. Larger screens typically have a smaller pixel density if the resolution is low. Choose the screen size based on what you’re using the monitor for. Common uses such as work or gaming can be supported by a standard screen size for the most part. In fact, you should be able to find a 32-inch 4k monitor for a reasonable price.

High resolutions yield a clearer and more visually appealing image quality than low resolutions. The resolution indicates the number of pixels contained within a monitor using a width x height format. For office workers, a 1920×1080 or 1080p is the minimum requirement, but you can opt for a sharper image quality with a 4k resolution if you prefer.

If excellent colour contrast is a significant priority for your technological needs, then an IPS LCD monitor is the right choice. IPS offers better colour contrast than both VA and TN panels combined. This panel type also boasts excellent colour accuracy, screen consistency, and overall clarity.

Although IPS display technology comes at a slightly higher price point than TN panels, there’s a good reason for that. The contrast ratio on an IPS LCD monitor is superb in every sense of the word. Companies rate their product’s contrast ratios to indicate the differences between lighter and darker image elements. Larger ratios typically mean greater image clarity, which is certainly a feature worth noting in high-end IPS LCD displays.

Twisted nematic effect was a breakthrough LCD technology that became dominant during the 1980s and 1990s. However, TN panels suffered from several limitations and the disadvantages of TN display technology restricted the applications of LCD.

Nonetheless, the introduction of in-plane switching or IPS during the mid 1990s and its mass popularity in mid 2000s marked another breakthrough in LCD technology. IPS display technology has expanded the application of LCD to include high-definition television and computer monitors, as well as high-resolution mobile devices such as smartphones and tablets.

This article lists down and describes the advantages and disadvantages of in-plane switching display technology, thus also discussing the strengths and limitations or drawbacks of IPS LCD panels.

One of the notable advantages of IPS LCD panels over TN panels is color reproduction that further translates into color accuracy and better image quality.

Note that a typical TN panel only has a 6-bit RGB color depth. This means that it is only capable of producing 262,144 possible colors. On the other hand, a conventional IPS has an 8-bit RGB color depth capable of producing 16.7 million possible colors.

Though another type of LCD technology called virtual alignment or VA has a similar 8-bit RGB color depth, several manufacturers have introduce high-end IPS panels with 16-bit to 24-bit RGB color depth.

Active-matrix organic light-emitting diode or AMOLED display technology is a close competitor of IPS display technology. Between the two however, IPS has better color accuracy because AMOLED panels are prone to producing images with strong or highly saturated colors.

When compared against TN panels and VA panels, as well as AMOLED panels thereby, IPS LCD panels produce more vibrant images and more realistic colors. This advantage means that in-plane switching is an ideal display option for use in multimedia consumption, as well as in color critical work such as photo editing, graphic design, and video editing.

TN panels also suffer from very limited viewing angle as demonstrated by poor off-axis image quality. The introduction of VA LCD technology tried to resolve this limitation. But VA panels suffer from color shifts when viewed from a slightly different angle.

Nonetheless, wide viewing angle is another advantage of in-plane switching over TN and VA display technologies. Typical IPS LCD panels will produce no image distortion and relatively minimal color shifts when viewed from different angles while high-end IPS panels will display consistent contrast and brightness levels under different viewing angles.

This advantage of IPS panels is made possible because the technology involves the capacity to change the physical behavior of the liquid crystal layer by making the crystal molecules respond to the electric field in parallel to the TFT. This also results in better color reproduction.

For smartphone and tablet applications, the aforementioned advantage means that these portable devices can be held in various angles and eye levels. This advantage also means that television sets or computer monitors with IPS panels offer a better visual experience than other LCD panels.

Colors and images on an IPS panel remain considerably more visible under bright outdoor lights or direct sunlight than other display technologies. This is an advantage of in-plane switching technology over TN and AMOLED display technologies.

The better color reproduction coupled with better viewing angle and backlighting make IPS usable or viewable under direct sunlight. Note that TN panels suffer from poor visibility under direct sunlight because of its limited color depth. AMOLED panels, on the other hand, have similar problems because of the inapplicability of backlighting.

Dead pixels are an inherent issue affecting different LCD technologies. The lifespan of IPS LCD panels cannot be generally compared against the lifespan of TN panels or VA panels.

However, it is important to note that TN display technology is easier to implement and thus, TN panels are easier to produce. This further translates to more manufacturers producing TN panels, thereby increasing the tendency for low manufacturing standards. Some manufacturers are also producing low-end TN panels to meet demands for cheaper LCD.

When generally compared against typical TN panels nonetheless, IPS panels might have a longer lifespan. On the other hand, the lifespan of VA panels might be comparable with IPS. Of course, it is important to remember that this is an overstatement.

Compared to AMOLED panels however, IPS panels have obvious longer lifespan. Remember that one of the notable limitations of AMOLED is its susceptibility to noticeable pixel degradation and faster screen burn-ins.

When compared to TN panels, IPS LCD panels have better contrast ratio because it has better color depth. However, VA panels and AMOLED panels have better contrast ratio than IPS panels.

Backlighting can be blocked effectively in a vertical alignment display technology. This produces deeper blacks and subsequently, higher contrast ratio compared to in-plane switching display technology.

On the other hand, AMOLED panels naturally produce deep blacks because they represent the absence of light and thus, the absence of color. This results in higher contrast ratio. Although IPS technology produces intense whites, high-end AMOLED panels can also rival typical IPS panels in this regard.

Another disadvantage of IPS panels when compared against TN panels and AMOLED panels is power consumption. In-plane switching technology consumers more power than TN or AMOLED display technologies.

Note that TN panels are suitable for battery-operated and low-powered devices. On the other hand, a typical IPS panel requires 15 percent more power than a TN panel. IPS panels also require a strong backlighting to improve display clarity unlike AMOLED panels.

This drawback means that consumer electronic devices featuring an IPS panel have more power requirements than counterpart devices equipped with TN or AMOLED panels. This affects the overall energy efficiency rating and battery life performance of a specific device.

Other disadvantages of in-plane switching technology are slow pixel response time and low refresh rate. The response time and refresh rate of IPS panels are slower and lower than TN or AMOLED panels.

Pixel response time is the duration it takes a single pixel to transition from one state to another. Refresh rate is the frequency in which the image in a display is refreshed. Slow pixel response time and low refresh rate create ghosting effects and motion blurs around a moving image. In addition, both ghosting effects and motion blurs are more straining to the eyes.

This limitation makes an IPS panel an unsuitable display option for use in fast-paced and competitive gaming. TN display technology has the faster response time and higher refresh rates among existing LCD technologies. This is the reason why some hardcore gamers still prefer TN panels to IPS or VA panels despite having poor color reproduction.

Manufacturers have produced IPS panels with better response times and refresh rates. However, these panels are more expansive than TN panels, thus making them unappealing to budget-conscious consumers.

Manufacturing IPS LCD panels is costlier than manufacturing TN panels because of the involved engineering complexity. This higher manufacturing costs results in higher prices for end consumers.

Entry-level laptops such as netbooks, as well as feature phones and budget smartphones are commonly equipped with TN panels. Devices with IPS LCD panels are relatively more expensive. Note that high-grade IPS panels are featured in top-of-the-line products with higher price tags.

Between in-plane switching and AMOLED display technologies however, both are also costly to manufacture and both IPS and AMOLED panels are commonly featured in premium products such as high-end smartphones and tablet computers.

From the aforementioned, in-planed switching display technology outperforms other LCD technologies to includw twisted nematic and vertical alignment. The strengths or advantages of IPS LCD panels center on better image production and visual performance stemming from having higher color depth, more accurate color reproduction wider viewing angle, and better visibility under direct sunlight.

Nonetheless, the drawbacks and disadvantages of IPS LCD panels make them unappealing to some extent. They are not as power efficient as TN or AMOLED panels. They are not as inexpensive or as readily accessible as TN panels as well. These disadvantages translate to the limited applications of in-plane switching technology when cost or price and power consumption are factored in.

The key difference between IPS LCD and AMOLED displays is that the IPS LCD produces realistic colors whereas the AMOLED produces saturated colors.  The colors are more accurate, and the sharpness and clarity are also higher on the LCD display. The viewing angles are better, and the contrast ratio is wider on the AMOLED display as well.

When we are to buy a smartphone, we will come across mainly two types of displays. One is the IPS LCD display whereas the other will be the AMOLED display. Both of these displays come with advantages as well as disadvantages over the other. It is a noteworthy that all AMOLED or IPS LCD displays are not the same as manufacturers add proprietary technologies to the manufactured panels of both types. This is the reason two AMOLED or two IPS LCD displays may not have the sam
