tft lcd monitor vs ips manufacturer

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.

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.

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 two buzzwords the tech world has been chatting about for a number of years now is IPS, (In-Plane Switching) screen technology used for liquid crystal displays or LCD’s for short, and TFT (Thin-Film-Transistor) an active matrix screen technology, which is more expensive, but a sharper image.

Designed in the 1980’s, but not introduced until nearly a decade later, in 1996, by Hitachi, IPS technology is nothing new, and a type of LCD design that affords greater viewing angles and higher-quality color reproduction than the traditional TN or Twisted Nematic LCDs.

When Apple brought it to the public’s attention, it took off, and as they say, the rest is history; but, it really didn’t become widespread or worldwide until just the late 1990’s. Since then, IPS screens have been implemented in homes all over the world, with variations to suit one’s electronic needs.

TFT (Thin-Film-Transistor) Liquid Crystal Display is a thin display type, where a transistor embedded into each crystal gate; these transistors are then printed on thin-transparent film. The technology was designed to improve image qualities, such as contrast and addressability.

Also designed in the late 1980’s, TFT display technologies is just another variation of LCD displays that offer greater color, contrast, and response times as opposed to available passive matrix LCD’s. One of the primary differences between IPS and TFT display technologies is the cost. IPS is more expensive than TN technology. However, there are some key differences between the two that should be noted.

Before we go into the differences, let’s talk about features of each technology. Note that we’re not talking TVs, computer, or tablets, but screens on a much smaller scale, (think 7” or smaller) which uses different rules to fit that scale. First, it’s interesting to discover that the TFT display technologies is the most common type of color display technology; more monochrome displays still out-sell color, due to lower cost and lower power consumption, however, the narrow poor visibility of TFTs in direct sunlight is their downside; but I’m getting ahead of myself here.

IPS technology has come a long way in regards to cell phones and other LCD screens that are even much smaller. (Picture digital clocks on a radio, microwave, and hand-held games) Some of the features of an IPS screen include:Wider viewing angles – crystals are aligned horizontally rather than vertically, so it allows for better angled viewing, perfect for smaller screens, where you need to rotate the screen for better viewing

Brilliant color image – this is a huge advance in technology, from a Twisted Nematic (TN) display that only produced 6-bit color, to an 8-bit color display with the IPS technology

Variations to help with user’s viewing requirements or desires – there are several different forms of IPS technology: Super-IPS, (S-IPS) Advanced Super IPS, Advanced S-IPS, where the liquid crystal molecules stay parallel to the front and back panels, instead of perpendicular when a voltage is applied

TFT display technologies have developed over the years and have become quite popular in tech circles. The features offered with this advancing technology are:Superior color display – for technology that requires it or for consumers that desire color screens

Variety of displays, which can be interfaced through a variety of bus types, including 18 and 24 bit for red/green/blue, LVDS, and 8 bit and 16 bit for a CPU – many controllers allow for two or more different types of interfaces on the same TFT screen

Let me explain. As you can see, both have excellent color display and clarity; however, IPS screens offer greater color reproduction and viewing angles because of the way crystal orientation and polarizers are arranged. In a TFT screen, the structure of the crystals results in angular retardation in the light. The IPS screens thus offer less distortion properties. Other differences include power consumption and cost. With IPS screens, it takes more power (up to 15% more) than with a TFT screen. If you’re on a monitor, such as a computer screen that’s bigger than 7 inches, it will drain your battery faster than if you’re on a 3.5” screen. Regarding cost, IPS panels are more expensive to produce than TFT panels.

Here’s why:IPS screens are popular and in high demand with professionals including surgeons and photographers or pretty much any profession that requires color reproduction, therefore, because the demand is high, the price goes up. (way to love economics) Also, less manufactures are building IPS at this time.

The color channels increase from 6 bits (TN displays) to 8 bits (IPS displays) to ensure the precision of shades per color channel, thus increasing manufacturing costs

If you want the benefits of having a Smartphone without a huge price tag, then TFT devices are your best bet. Another difference is that IPS screens have longer response times than TFT screens, so the lag output is greater. A few other key differences to be aware of are that with IPS panels, you get a bigger variety of panels, as was discussed above, with their super, advanced, and so forth developments, giving the consumer options, and IPS screens that can display 24-bit TrueColor; they also stay color-accurate and remain stable.

Because of their superior color and clarity of images, devices using an IPS screens are easy to install on walls, due to their compact form and low-depth. The Super IPS screens offer a higher angle of 170˚ for better clarity and wider viewing, particularly at night. Images remain stable and clear and not sparkly, shiny, like other screens; they also have a longer battery life and screen life, (on smaller screens of course) because of the lower electrical output. The release of heat is lower, again because of the reduced electrical consumption. The colors are also more vibrant and clear, not pixelated like other lower quality-type devices. As mentioned earlier, there are also many variations of IPS technology to suit your needs and desires.

Now we will go over the downside of IPS screens, which we briefly touched on above, which includes a major disadvantage: cost. If you’re just looking for an average Smartphone or don’t need all the fancy coloring and clarity for LCD displays, then cost may not be a big factor; however, this is the main reason why IPS technology is beginning to come down. As with every new invention, discovery or technology, demand is everything. Another disadvantage is that colors may not always transcribe correctly or accurately, which may or may not be a deterrent. Also, high resolutions are not always readily available for personal applications. In certain circumstances, the brightness may not be enough, especially in darkness.

Steve Jobs said it best: “Design is not just what it looks like and feels like. Design is how it works.” I tend to agree with him. With TFT display technologies, less energy consumption is a big deal, especially when dealing with bigger screens, and of course less electricity means lower cost, overall. The visibility is sharper, meaning no geometric distortion, which is great for these tired, old eyes. The response time and physical design of the screens are also appealing. TFT displays can also save space and be placed virtually anywhere in an office or home, because of the brightly lit feature and crisp clear images.

Some cons of TFT screens deal with the viewing angle, which create distortion, resulting in a less-than-perfect image. Static resolution, meaning the resolution can’t be changed, may also cause a problem, but newer models seem to have tackled that issue. The accuracy of the display of colors is not perfect, specifically strong blacks and bright whites, so when printing an image, it may not display the spectrum of colors.

And there you have it. In the future, even this superb technology will change and new, more exciting technology will take its place. But until then, IPS & TFT screens are forging ahead with their own advances and improvements, so stayed tune. You don’t want to miss it.

Focus Display Solutions (www.FocusLCDs.com) offers off-the-shelf Color TFT display technologies in both TN and IPS. Many of the color modules contain built in touch panels.

If you want to buy a monitor, normally there are only two choices: TFT display or IPS display. In order to make the right purchase decision, it is important to know the technologies behind the two displays.

The word TFT means thin film transistor. It is the technology that is used in LCD or Liquid Crystal Display. Here you should know that this type of LCDs is also categorically referred to as active-matrix LCDs. It says 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 (actually to make the liquid crystal molecules between two electrodes twisting). 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.

The brightest feature TFT displays have is its low cost because of the simpler process of manufacturing, low cost material and one of the oldest technologies for LCD displays. But they are not the best quality considering poor viewing angles, lower contrast ratio, slower response time, lower aperture ratio (each pixel not bright enough) and the worst is that there is one view angle with Gray Scale Inversion (reversed image), see the bottom one of picture 1 below.

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 with more enhanced features and more widespread usability. IPS LCD monitors consist of the following high-end features. It has a much wider viewing angle, more consistent, accurate color in all viewing directions, it has higher contrast, faster response time. But IPS display is not perfect as its higher manufacturing cost. See the Fig.2 below

Both TFT display and IPS display are active matrix displays, neither can’t emit light like OLED, it has 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 and therefore utilize less power and require less depth by design. Actually neither TFT display nor IPS display can produce color, there is a layer of RGB (red,green,blue) color filter in each LCD pixel to make the LCD show color. If you use a magnifier to see your monitor, you will see RGB color. By switching on/off and different levels of RGB brightness, we can produce a spectrum of many colors.

Wider Viewing Angles: IPS Display Wins. If youdon’t want to compromise 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.

Faster Response Time: IPS Display Wins. IPS TFT Screens have around 0.3 milliseconds response time while TN TFT Screens respond around 10 milliseconds which makes the latterpoor for gaming purposes.

Cost: TFT Display Wins (around 30%-50% lower). The TFT lcd production technology is more mature than IPS LCD, it has a better production yield than IPS LCD.

Lower Energy Consumption: TFT Display wins. TN TFT LCD has more than around 15% power consumption than IPS lcd. The reason still comes from the array way of liquid crystal inside the IPS LCD screen. Because the liquid crystal molecules are arrayed in the electrode plane, the power would be saved for switching on liquid crystal in IPS screen than twisting it in TFT lcd screens, that is the reason IPS screen is better than TN TFT lcd in power consumption. Regarding the IPS LCD screen have better contrast, but in the same time, it have less transmissive ratio (transmittance), so we need more light from lcd backlight, if used more led chips, so it also need more power to the lcd backlight, so the total display module might need more power consumption if the backlight driving current for IPS LCD panel. so we need to be moreconcerned about the backlight current consumption instead of the IPS TFT panel itself. The main power consumption would be from the lcd backlight, not the IPS TFT panel. Battery life will likely be longer if other hardware is the same.

Better “Image or Pixel Sticking” or “Ghosting” (Image Sticking is when an image will stay on for a short time when instead it should be off): Hard to say depending on different display screen manufacturers. Generally speaking, TFT Display has aslightly better chance not to have the issue.

In summary, normally high-end products like Apple Mac monitors and Samsung mobile phones most likely use IPS panels. Some of the even high end TV and mobile phones use AMOLED( Active Matrix Organic Light Emitting Diodes) Displays. The technology provides even better color reproduction, image quality, better color gamut, less power than LCD technology. Please note that OLED includes AMOLED and PMOLED (Passive Matrix Organic Light Emitting Diodes). What you need to choose is AMOLED for your TV and mobile phones instead of PMOLED. If you have more budget, you can have your screen with touch screen, most of the touch nowadays uses PCAP (Projective Capacitive) touch panel. This kind of touch technology was first introduced by Steven Jobs in the first generation iPhone. Of course, a TFT LCD display can always meet the basic needs with reasonable price.

The tried and trusted TFT is the display of choice for most industrial designs, but it does have its limitations in viewability and colour vibrancy. But what about the relatively new technology, IPS (in plane switching) which has turned the TFT into a super-TFT? What are the benefits and drawbacks of each?

IPS derives its name from the fact that the liquid-crystal molecules are aligned in parallel with the glass plates, whereas the TN principle adopted in conventional TFT displays is based on perpendicular alignment of the molecules. In an IPS display, the crystals remain oriented in parallel whether the pixel is turned on or off.

A TFT display is a form of Liquid Crystal Displaywith thin film transistors for controlling the image formation. The TFT technology works by controlling brightness in red, green and blue sub-pixels through transistors for each pixel on the screen. The pixels themselves do not produce light; instead, the screen uses a backlight for illumination. Discover our TFT Products

Because the pixels block light when in the off state (the opposite situation to conventional TFT), IPS TFT exhibits high contrast and the background is true black when the display is powered down.

Display choice really does depend on your application, end user and environment. It may be a higher-grade IPS is needed to satisfy outdoor requirements, or a lower cost standard TFT display is sufficient. Before you make your choice, why speak with us and we will be happy to talk you through your options.

The word TFT means Thin Film Transistor. It is the technology that is used in LCD or Liquid Crystal Display. It is also called Active Matrix LCD which differentializes from Passive Matrix LCD. A TFT substrate is composed of a matrix of pixels and ITO electrode (Indium Tin Oxide, a transparent electric conducting film) each with a TFT device and is so called array. Thousands or millions of these pixels together create an image on the display. The diagram below shows the simple structure of a pixel.

As long as there are TFT in the LCD, the LCD should be called a TFT LCD. But when the TFT LCD display was first commercialized, 100% TFT LCDs were TN (twisted Nematic) type TFT displays. As TN is a very technical term so most of the users ignored TN and named TN type TFT display as TFT display. While the newly developed TFT LCD display technologies such as IPS (in-plane-switching ) type TFT display, O-Film type TFT display (derived from TN type TFT display), MVA( Multi-domain Vertical Alignment) type TFT display, AFFS (Advanced Fringe Field Switching) type TFT display, they are widely call IPS display, O-Film display, MVA display and AFFS display. As the above terms have been used for long and widely accepted in the market, we will not try to correct the misunderstanding here. We will still use the TFT display (should be TN type TFT display) and IPS display (should be IPS type TFT display) in the following.

The twisted nematic effect (TN-LCD) was a main technology breakthrough that made LCDs practical. TN LCDs first make battery powered devices popular. TN-LCD displays led to the rapid expansion in the display field, quickly replacing other displays like LEDs, plasma, CRTs etc. By the 1990s, TN LCDs were widely used in portable electronics.

The TN display takes advantage of the ability of the nematic substance to rotate the polarization of light beams passing through it. Two polarizing filters, parallel planes of glass with their polarizing lines oriented at right angles with respect to each other, are positioned on either side of the liquid crystal. When light enters the display, it is polarized by the input filter. In the absence of an electric field, all the incoming light is transmitted. This is because the light polarization is rotated 90 degrees by the nematic liquid crystal, and the light therefore passes easily through the output filter, which is oriented to match the 90-degree shift. With the application of a voltage, an electric field is produced in the nematic liquid crystal. Under these conditions the polarization effect is reduced. If the voltage is large enough, the polarization effect disappears altogether, and the light is blocked by the output polarizing filter. The diagram below shows how a TN LCD works.

The best feature of TFT displays is the low cost due to a simpler manufacturing process, low-cost raw materials, and one of the oldest technologies for LCD displays. But they are not the best quality considering poor viewing angles, lower contrast ratio, slower response time, lower aperture ratio (each pixel not bright enough), and the worst is that there is one view angle with gray scale inversion (reversed image), see the below picture for reference.

IPS (in-plane-switching) technology is also one type of TFT LCD display. The basic LCD structure is similar to TN type TFT display but the inside display schematic is different.

In 1992, Hitachi researchers in Japan first developed details of the IPS technology. NEC and Hitachi became early manufacturers of active-matrix addressed LCDs based on the IPS technology. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and in-plane switching subsequently remained the dominant LCD designs through 2006. IPS technology is widely used in LCD panels for TVs, laptops, monitors, and smartphones. Apple Inc. products branded with the label Retina Display (such as iPhone 4 onward, iPad 3 on, iPad Mini 2 on, MacBook Pro with Retina display adopted IPS LCDs with LED backlighting.

An IPS LCD panel, when no electric field is applied to the liquid crystal cells, the cells naturally align in liquid crystal cells in a horizontal direction between two glass substrates which blocks the transmission of light from the backlight. This makes the display dark and results in a black display screen. When an electric field is applied, the liquid crystal cells are able to rotate through 90° allowing light to pass through resulting in a white display screen. IPS panels have superior image quality, good contrast ratio and wide viewing angles of up to 170°. IPS panels are well suited for graphics design and other applications which require accurate and consistent color reproduction.

In summary, 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. Of course, a TFT LCD display can always meet the basic needs at the most efficient price.

TFT screen is generally referred to as "active panels" for most liquid crystal displays, and the core technology of "active panels" is thin film transistor, or TFT, which has led people to call active panels TFT. Although such a name is not appropriate, it will be the case for a long time. The difference between TFT screen and IPS screen is as follows:

The working mode of the TFT screen is that each liquid crystal pixel on the liquid crystal display is driven by an integrated thin film transistor, which is TFT. Simply put, TFT is to configure a semiconductor switching device for each pixel, and each pixel can be directly controlled by a dot pulse. And since each node is relatively independent, continuous control can also be performed.

IPS technology changes the arrangement of liquid crystal molecule particles, adopts horizontal conversion technology to speed up the deflection of liquid crystal molecules, guarantees the picture clarity and super expressive power when shaking, and eliminates the external pressure of traditional liquid crystal displays. Blurring and water ripples will appear when shaken. Because the liquid crystal molecules rotate in the plane, the IPS screen is born with a fairly good viewing angle performance, and the four axial directions can achieve a viewing angle close to 180 degrees.

Although the IPS screen technology is very powerful, it is still a technology based on TFT, and the essence is a TFT screen. No matter how strong IPS is, it is derived from TFT after all, so TFT quality and IPS quality are integrated.

Technology can be confusing because it evolves quickly, and there are complex acronyms for almost everything. If you are thinking ofbuildinga monitor or want to learn about the technology, you will encounter the term TFT Monitor at some point.

A lot goes on behind the glass surface, and we will look at this in comparison to other technologies to paint a clear picture of what TFT is and how it evolved.

TFT is an acronym for Thin Film Transistor, and it is a technology used in Liquid Crystal Display screens. It came about as an improvement to passive-matrix LCDs because it introduced a tiny, separate transistor for each pixel. The result? Such displays could keep up with quick-moving images, which passive-matrix LCDs could not do.

Also, because the transistors are tiny, they have a low power consumption and require a small charge to control each one. Therefore, it is easy to maintain a high refresh rate, resulting in quick image repainting, making a TFT screen the ideal gaming monitor.

The technology improved on the TN (Twisted Nematic) LCD monitor because the shifting pattern of the parallel, horizontal liquid crystals gives wide viewing angles. Therefore, IPS delivers color accuracy and consistency when viewed at different angles.

Both TFT and IPS monitors are active-matrix displays and utilize liquid crystals to paint the images. Technically, the two are intertwined because IPS is a type of TFT LCD. IPS is an improvement of the old TFT model (Twisted Nematic) and was a product of Hitachi displays, which introduced the technology in 1990.

The monitors can create several colors using the different brightness levels and on/off switches. But unlike OLED, both TFT and IPS do not emit light, so most have bright fluorescent lamps or LED backlights to illuminate the picture. Also, neither of them can produce color, so they have an RGB color filter layer.

Easy to Integrate and Update: By combining large-scale semiconductor IC and light source technology, TFTs have the potential for easy integration and updating/development.

Wide Application Range: TFTs are suitable for mobile, desktop screens, and large-screen TVs. Additionally, the technology can operate at a temperature range of -20°C to +50°C, while the temperature-hardened design can remain functional at temperatures not exceeding -80°C.

Impressive Display Effect: TFT displays use flat glass plates that create an effect of flat right angles. Combine this with the ability of LCDs to achieve high resolutions on small screen types, and you get a refreshing display quality.

Good Environmental Protection: The raw materials used to make TFT displays produce zero radiation and scintillation. Thus, the technology does not harm the user or the environment.

Mature Manufacturing Technology: TFT technology came into existence in the 60s. Over time, its manufacturing technology has matured to have a high degree of automation, leading to cheaper, large-scale industrial production.

Wide View Angle: One of the main advantages of IPS screens is their wide viewing angle due to the horizontal liquid crystals. They do not create halo effects, grayscale, or blurriness, but these are common flaws with TFTs.

Better Color Reproduction and Representation: The pixels in TFTs function perpendicularly after activation with the help of electrodes. However, IPS technology makes the pixels function while parallel horizontally. Thus, they reflect light better and create a more original and pristine image color.

Faster Frequency Transmittance: Compared to TFT, IPS screens transmit frequencies at about 25ms, which is 25x faster. This high speed is necessary to achieve wide viewing angles.

Liquid Crystal Display (LCD) is a front panel display that utilizes liquid crystals held between two layers of polarized glass to adjust the amount of blocked light. The technology does not produce light on its own, so it needs fluorescent lamps or white LEDs.

As explained earlier, TFT improved on the passive-matrix LCD design because it introduces a thin film transistor for each pixel. The technology reducescrosstalkbetween the pixels because each one is independent and does not affect the adjacent pixels.

LED screens are like the new kids on the block in the display market, and they operate very differently from LCDs. Instead of blocking light, LEDs emit light and are thinner, provide a faster response rate, and are more energy-efficient.

Since IPS is a type of TFT, when comparing the two, we are essentially looking at the old Thin-Film Transistor technology (Twisted Nematic) vs. the new (IPS). Even though TN is relatively old, this digital display type has its advantages, a vital one being the fast refresh rate. This feature makes such screens the preferred option by competitive gamers.

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.

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.

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 computers.

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.

A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technologyactive matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments.

In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark"s ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968. In 1971, Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated a 2-by-18 matrix display driven by a hybrid circuit using the dynamic scattering mode of LCDs.T. Peter Brody, J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories developed a CdSe (cadmium selenide) TFT, which they used to demonstrate the first CdSe thin-film-transistor liquid-crystal display (TFT LCD).active-matrix liquid-crystal display (AM LCD) using CdSe TFTs in 1974, and then Brody coined the term "active matrix" in 1975.high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.

The circuit layout process of a TFT-LCD is very similar to that of semiconductor products. However, rather than fabricating the transistors from silicon, that is formed into a crystalline silicon wafer, they are made from a thin film of amorphous silicon that is deposited on a glass panel. The silicon layer for TFT-LCDs is typically deposited using the PECVD process.

Polycrystalline silicon is sometimes used in displays requiring higher TFT performance. Examples include small high-resolution displays such as those found in projectors or viewfinders. Amorphous silicon-based TFTs are by far the most common, due to their lower production cost, whereas polycrystalline silicon TFTs are more costly and much more difficult to produce.

The twisted nematic display is one of the oldest and frequently cheapest kind of LCD display technologies available. TN displays benefit from fast pixel response times and less smearing than other LCD display technology, but suffer from poor color reproduction and limited viewing angles, especially in the vertical direction. Colors will shift, potentially to the point of completely inverting, when viewed at an angle that is not perpendicular to the display. Modern, high end consumer products have developed methods to overcome the technology"s shortcomings, such as RTC (Response Time Compensation / Overdrive) technologies. Modern TN displays can look significantly better than older TN displays from decades earlier, but overall TN has inferior viewing angles and poor color in comparison to other technology.

The transmittance of a pixel of an LCD panel typically does not change linearly with the applied voltage,sRGB standard for computer monitors requires a specific nonlinear dependence of the amount of emitted light as a function of the RGB value.

Initial iterations of IPS technology were characterised by slow response time and a low contrast ratio but later revisions have made marked improvements to these shortcomings. Because of its wide viewing angle and accurate color reproduction (with almost no off-angle color shift), IPS is widely employed in high-end monitors aimed at professional graphic artists, although with the recent fall in price it has been seen in the mainstream market as well. IPS technology was sold to Panasonic by Hitachi.

Most panels also support true 8-bit per channel color. These improvements came at the cost of a higher 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.

Less expensive PVA panels often use dithering and FRC, whereas super-PVA (S-PVA) panels all use at least 8 bits per color component and do not use color simulation methods.BRAVIA LCD TVs offer 10-bit and xvYCC color support, for example, the Bravia X4500 series. S-PVA also offers fast response times using modern RTC technologies.

A technology developed by Samsung is Super PLS, which bears similarities to IPS panels, has wider viewing angles, better image quality, increased brightness, and lower production costs. PLS technology debuted in the PC display market with the release of the Samsung S27A850 and S24A850 monitors in September 2011.

TFT dual-transistor pixel or cell technology is a reflective-display technology for use in very-low-power-consumption applications such as electronic shelf labels (ESL), digital watches, or metering. DTP involves adding a secondary transistor gate in the single TFT cell to maintain the display of a pixel during a period of 1s without loss of image or without degrading the TFT transistors over time. By slowing the refresh rate of the standard frequency from 60 Hz to 1 Hz, DTP claims to increase the power efficiency by multiple orders of magnitude.

Due to the very high cost of building TFT factories, there are few major OEM panel vendors for large display panels. The glass panel suppliers are as follows:

External consumer display devices like a TFT LCD feature one or more analog VGA, DVI, HDMI, or DisplayPort interface, with many featuring a selection of these interfaces. Inside external display devices there is a controller board that will convert the video signal using color mapping and image scaling usually employing the discrete cosine transform (DCT) in order to convert any video source like CVBS, VGA, DVI, HDMI, etc. into digital RGB at the native resolution of the display panel. In a laptop the graphics chip will directly produce a signal suitable for connection to the built-in TFT display. A control mechanism for the backlight is usually included on the same controller board.

The low level interface of STN, DSTN, or TFT display panels use either single ended TTL 5 V signal for older displays or TTL 3.3 V for slightly newer displays that transmits the pixel clock, horizontal sync, vertical sync, digital red, digital green, digital blue in parallel. Some models (for example the AT070TN92) also feature input/display enable, horizontal scan direction and vertical scan direction signals.

New and large (>15") TFT displays often use LVDS signaling that transmits the same contents as the parallel interface (Hsync, Vsync, RGB) but will put control and RGB bits into a number of serial transmission lines synchronized to a clock whose rate is equal to the pixel rate. LVDS transmits seven bits per clock per data line, with six bits being data and one bit used to signal if the other six bits need to be inverted in order to maintain DC balance. Low-cost TFT displays often have three data lines and therefore only directly support 18 bits per pixel. Upscale displays have four or five data lines to support 24 bits per pixel (truecolor) or 30 bits per pixel respectively. Panel manufacturers are slowly replacing LVDS with Internal DisplayPort and Embedded DisplayPort, which allow sixfold reduction of the number of differential pairs.

Liquid crystal display (LCD) technology is one of the most widely used screen technologies. It’s instantly recognizable because of its iconic flat-panel display.

In fact, within LCD, there are several technologies each with its own strengths and weaknesses when it comes to rendering images and video effectively.

If you’re wondering what makes IPS different and if it is the right display choice for your viewing desires, this article will compare IPS and LCD technologies with an explanation of how both work and the features they bring to your experience.

IPS was developed to overcome critical limitations of legacy LCD technologies, like twisted nematic field effect (TN) matrix and vertical alignment (VA).

IPS can achieve a much wider viewing angle than the older LCD technologies. It can achieve a viewing angle of up to 178 degrees in horizontal and vertical directions, making it an ideal LCD for wide-screen television viewing.

IPS screens can achieve rates that range from 60 Hz to as much as 390 Hz. This keeps IPS as a contender technology for gaming screens even though its response rate is not as fast as more modern screen technologies like OLED.

The linear response, higher bit depth, improved contrast, and image consistency give IPS screens exemplary color accuracy. They also have little to no color shift, which often affects VA displays.

An IPS screen can be confidently used for graphic and video design work if the resolution is suitable. It renders 256 colors faithfully, but its backlit screen creates a low native contrast ratio.

IPS retains its commercial appeal because of the sheer range of screens that are available, ranging from 23.8 inches right through to 85-inch options.

The versatility of IPS screen technology enables it to be used for a range of applications and devices, including televisions, smartphones, smartwatches, and tablets.

Like other LCDs, overheating of the screen can cause blackening defects. Manufacturers have developed liquid crystal formulations with a higher critical temperature to prevent this.

Gravity defects can affect any type of LCD screen. This is where the cohesive power of the liquid crystal in the screen is low, causing it to flow down to the bottom of the screen with a yellowing defect.

With this type of LCD screen, the liquid crystals are in a plane that lies parallel to its glass substrate. Voltage is applied through opposing electrodes on the glass substrate to activate the crystals in a unified plane. Each pixel in an IPS screen requires two transistors to achieve this switching.

Katsumi Kondo of Hitachi was a significant developer of IPS technology and, by 1992, Hitachi developers had established the principles of in-plane switching, later releasing the first IPS screen.

IPS technology has continued to be used for screens that include laptops, tablets, and even smartwatches. Its viewing angles, refresh rates, and color accuracy makes it a suitable screen for gaming and design applications.

LCD was the first flat-panel display technology and has diversified over the last century to create screens suitable for a wide range of applications.

Twisted nematic (TN) LCD consists of liquid crystals that rotate (twist) to allow the passage of light when voltage is applied. Adjustments to the level of voltage lead to changes in light polarization and can be used to display an image.

Without the application of voltage, the crystals remain in this position and the screen is dark. When voltage is applied, the crystals shift to a tilted position allowing light to pass through and an image to become visible. VA can achieve greater contrast than IPS, but it is still hampered by an extremely narrow viewing angle.

By the 1960s, the electro-optic properties of liquid crystals were known and, later in the decade, the concept of TN LCD was advanced with the development of screens for watches and other displays during the 1970s.

IPS monitors are the most advanced LCD technologies. They are still commercially viable with leading manufacturers like LG and Samsung selling IPS televisions with exemplary image quality.

Because IPS screens are a relatively older technology, it is possible to get a high-quality screen for prices that are much lower than the newer LED technologies. Older, TN LCD screens simply do not have the responsiveness, image quality, or color accuracy to render modern content effectively. They have become legacy technologies that are not being produced anymore.
