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 liquid crystal displays used in calculators and other devices with similarly simple displays have direct-driven image elements, and therefore a voltage can be easily applied across just one segment of these types of displays without interfering with the other segments. This would be impractical for a large display, because it would have a large number of (color) picture elements (pixels), and thus it would require millions of connections, both top and bottom for each one of the three colors (red, green and blue) of every pixel. To avoid this issue, the pixels are addressed in rows and columns, reducing the connection count from millions down to thousands. The column and row wires attach to transistor switches, one for each pixel. The one-way current passing characteristic of the transistor prevents the charge that is being applied to each pixel from being drained between refreshes to a display"s image. Each pixel is a small capacitor with a layer of insulating liquid crystal sandwiched between transparent conductive ITO layers.
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.
Most TN panels can represent colors using only six bits per RGB channel, or 18 bit in total, and are unable to display the 16.7 million color shades (24-bit truecolor) that are available using 24-bit color. Instead, these panels display interpolated 24-bit color using a dithering method that combines adjacent pixels to simulate the desired shade. They can also use a form of temporal dithering called Frame Rate Control (FRC), which cycles between different shades with each new frame to simulate an intermediate shade. Such 18 bit panels with dithering are sometimes advertised as having "16.2 million colors". These color simulation methods are noticeable to many people and highly bothersome to some.gamut (often referred to as a percentage of the NTSC 1953 color gamut) are also due to backlighting technology. It is not uncommon for older displays to range from 10% to 26% of the NTSC color gamut, whereas other kind of displays, utilizing more complicated CCFL or LED phosphor formulations or RGB LED backlights, may extend past 100% of the NTSC color gamut, a difference quite perceivable by the human eye.
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.
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 2004, Hydis Technologies Co., Ltd licensed its AFFS patent to Japan"s Hitachi Displays. Hitachi is using AFFS to manufacture high end panels in their product line. In 2006, Hydis also licensed its AFFS to Sanyo Epson Imaging Devices Corporation.
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.
The bare display panel will only accept a digital video signal at the resolution determined by the panel pixel matrix designed at manufacture. Some screen panels will ignore the LSB bits of the color information to present a consistent interface (8 bit -> 6 bit/color x3).
With analogue signals like VGA, the display controller also needs to perform a high speed analog to digital conversion. With digital input signals like DVI or HDMI some simple reordering of the bits is needed before feeding it to the rescaler if the input resolution doesn"t match the display panel resolution.

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.
Before purchasing any Smartphone, everyone goes through a list of specifications. This list includes display type, screen size, battery backup, supported operating system, total internal memory, and many others. Today, we have brought a comprehensive study of the significant display technologies available nowadays.
This article will introduce you to AMOLED vs OLED display technologies. Then, we will discuss the properties of both display technologies, followed by the difference between AMOLED vs OLED.
It stands for Natural Light-Emitting Diode, a type of LED technique that utilises LEDs wherein the light is of organic molecules that cause the LEDs to shine brighter. These organic LEDs are in use to make what are thought to be the best display panels in the world.
When you make an OLED display, you put organic films among two conductors to make them. As a result, a bright light comes out when electricity is used—a simple design with many advantages over other ways to show things.
OLEDs can be used to make emissive displays, which implies that each pixel can be controlled and emits its very own light. As a result, OLED displays have excellent picture quality. They have bright colours, fast motion, and most importantly, very high contrast. Most of all, “real” blacks are the most important. The simple design of OLEDs also makes it easy to create flexible displays that can bend and move.
PMOLED stands for Passive Matrix Organic Light Emitting Diode. The PMOLEDs are easy to find and much cheaper than other LEDs, but they cannot work for a long duration as their lifespan is very short. Therefore, this type of display is generally for small devices up to 3 inches.
AMOLED stands for Active Matrix Organic Light Emitting Diode. This type of display is generally for large platforms. It contains TFT, which further consists of a storage capacitor. It also works on the same principle as OLED displays.
AMOLED offers no restriction on the size of the display. The power consumption of AMOLED is much less than other display technologies. The AMOLED provides incredible performance. It is thinner, lighter, and more flexible than any other display technology like LED, or LCD technology.
The AMOLED display is widely used in mobiles, laptops, and televisions as it offers excellent performance. Therefore, SAMSUNG has introduced AMOLED displays in almost every product. For example, Full HD Super AMOLED in Samsung Galaxy S4 and Samsung Galaxy Note 3, Super AMOLED in Samsung Galaxy S3, HD Super AMOLED in Samsung Galaxy Note, and HD Super AMOLED Plus in Samsung Galaxy S3. Apart from this, it is also used in AMOLED vs OLED creating the following:
So far, we have discussed OLED and AMOLED display technologies. Now, we will look at some of the differences between OLED and AMOLED display technology:
OLED comprises thin layers of the organic component, which emits light when the current passes through it. In this technology, each pixel transmits its own light. On the other side, AMOLED consists of an additional layer of thin-film transistors (TFTs). In AMOLED, the storage capacitors are used to maintain the pixel states.
While the technology is different among various manufacturers, Samsung’s edge AMOLED displays use plastic substrates with poly-Si TFT technology similar to how LG uses it in their POLED technology. This technology is what makes the possibility to build curved displays using an active-matrix OLED panel.
OLED display much deeper blacks as compared to the AMOLED displays. You cannot see the screen in AMOLED display under direct sunlight. The AMOLED display quality is much better than the OLEDs as it contains an additional layer of TFTs and follows backplane technologies.
These organic compounds are present between the protective layers of glass or plastic. Comparatively, AMOLED comprises an active matrix of OLED pixels along with an additional layer of TFTs. This extra layer is responsible for controlling the current flow in each pixel.
The OLED display offers a high level of control over pixels. Hence, it can be turned off completely, resulting in an excellent contrast ratio compared to the AMOLED displays and less power consumption. On the other side, AMOLED has faster refresh rates than OLEDs. Also, they offer a tremendous artificial contrast ratio as each pixel transmits light but consumes more power than OLEDs.
OLED displays are comparatively much thinner compared to the LCDs. Hence, it provides more efficient and bright presentations. In addition, OLED offers support for large display sizes compared to the traditional LCDs. AMOLEDs remove the limitation of display sizes. one can fit it into any display size.
Putting all the points mentioned above in view, the key difference to understand appropriately is that POLED is an OLED display with a plastic substrate. On the other hand, AMOLED is Samsung’s word for its display technology which is mainly for marketing. Therefore, most phone manufacturers having AMOLED displays mean that they are using Samsung displays. It is as simple as that. To add to that, all the curved display technology is made possible because of the usage of plastic substrate.
So, based on the points mentioned above, the difference between OLED and AMOLED displays, you can choose any of the two display technology at your convenience. Both are good, offer excellent performance, and are customised according to your requirements.
The AMOLED display has a higher quality than OLEDs since it has an additional layer of TTs and uses backplane technologies. When compared to OLED screens, AMOLED displays are far more flexible. As a result, they are substantially more expensive than an OLED display.
Window to the digital world, the display is one of the first seen features when selecting a smartphone, so a show must be good, and an AMOLED display offers the same. Offering a great viewing experience, here are the top 3 AMOLED screen smartphones available in the market right now:

Smartphone displays have advanced significantly in recent years, more so than most people realise in this technological age. Display screens are similar to windows in the mobile world, which has seen a tremendous transformation in innovative products in the last several years. People have gotten more selective when buying a phone in recent years, and although all of the functions are important, the display is always the most noticeable.
Cluster and center console display research: how Chinese manufacturers scramble for Mini LED/Micro LE market. The surging demand for intelligent and connected vehicles, in-vehicle infotainment systems and navigation systems among others gives a big boost to the automotive display market.
New York, Jan. 24, 2022 (GLOBE NEWSWIRE) -- Reportlinker.com announces the release of the report "Global and China Automotive LCD Cluster and Center Console Industry Report, 2021" - https://www.reportlinker.com/p06219667/?utm_source=GNW
The statistics from our automotive database show that in 2020 China shipped more than 35 million sets of passenger car displays (cluster, center console, entertainment display, HUD, etc.), up over 4% more than in the previous year.
Automotive display is a key booster to the digital transformation of automotive cockpits. The better performance of on-board computers enables the central computing unit to support LCD cluster, high-resolution infotainment display, HUD, electronic rearview mirror and other display systems, and provides technical support for multi-display systems.
From the new models launched in recent two years, it can be seen that large-size display and multi-screen display have been trends for automotive displays. High-end models have begun to pack at least 4 displays. Products like co-pilot seat entertainment display, control display, rear row entertainment display and streaming media rearview mirror have started finding application, and the demand for large-size displays has been soaring.
The installation of clusters shows that about 60% of new vehicles carry LCD clusters. In the first three quarters of 2021, 6.544 million LCD clusters were installed in passenger cars, a like-on-like spurt of 44.5%, of which 12.0-inch (incl.) to 13.0-inch (excl.) LCD clusters were most installed, up to 2.512 million units, up by 35.0%, and 10.0-inch (incl.) to 12.0-inch (excl.) LCD clusters grew at the fastest pace with the installations rocketing by 173.8% to 1.186 million units.
From center console displays, it can be seen that the installations of large-size ones have surged. In the first three quarters of 2021, 8.0-inch to 9.0-inch center console displays were most installed, up to 4.016 million units, up by 4.3% from the prior-year period, but with the proportion of the total center console display installations down 4.2 percentage points; the installations of 13.0-inch to 15.0-inch center console displays proliferated by 250.6%; that of 15.0-inch and above center console displays multiplied by 204.0%.
Cockpit electronics are heading in the direction of multi-display integration. Early in 2019, emerging carmakers have rolled out mass-produced models like LiXiang One and ENOVATE ME7 with 4 and even 5-screen displays. Traditional OEMs also step up efforts to deploy, having introduced multi-screen display products since 2020.
FAW Hongqi H9 unveiled in August 2020 bears dashboard, center console, and co-pilot seat entertainment displays, 2 rear row entertainment displays, and HUD. In addition, it also packs an electronic image acquisition and display system (i.e., streaming media rearview mirror) which consists of digital camera, image processing and high-definition digital display. The system uses the rear camera to project images onto the display, and displays them on the rearview mirror in digital format.
Great Wall Mecha Dragon introduced in November 2021 is equipped with 10.25-inch dashboard, 27-inch 4K center console display, 25-inch head-up display, two 1.6-inch touch bars, and two rear row capacitive touch screens, as well as external display technology at the rear.
In the future, as standards and regulations are improved, more vehicle displays will be used. For example, in June 2021, Zhejiang Society of Automotive Engineers was approved for release of group standard, the Performance Requirements and Test Methods of Passenger Car Digital Perspective A-pillar System. Neta Auto under Hozon Auto introduced its “transparent A-pillar”-enabled mass-production models with OLED flexible screens as display interfaces. The issuance of this standard will accelerate the application of “transparent A-pillar”.
The soaring demand for vehicle displays give impetus to development of new vehicle display technologies. In current stage, a-Si TFT LCD still prevail in vehicle display market, but advanced display technologies such as LTPS TFT LCD, OLED, mini LED backlight and micro LED are making their way into the market.
The year of 2020 saw the start of production of automotive OLED. Due to high cost, OLED, often larger than 7.2 inches, is largely used in high-end models, with applications including cluster, center console and copilot seat entertainment displays. Suppliers are led by LGD, Samsung Display and BOE.
2021 Mercedes-Benz S-Class sedans differ greatly from the previous generations in application of displays, changing the original siamesed center console display into a large waterfall display, a 12.8-inch vertical waterfall OLED screen with resolution of 1888×1728. They also pack a glasses-free 3D full LCD dashboard, HUD and rear row entertainment display, which connect with each other.
2021 Cadillac Escalade is equipped with an OLED AR perspective curved display with three screens total – a 7.2-inch driver information display, a 14.2-inch digital dashboard, and a 16.9-inch infotainment screen. Wherein, the cluster option features a large speedometer displaying temperature and time at the left and dynamics at the right. In addition, the display is in night mode where infrared technology is used to observe farther than human eyes.
Mini LED is a necessary transition phase from fine pitch LED to Micro LED. At present, most vehicle display technology companies have deployed Mini LED and Micro LED, and ever more vehicle projects use mini LED backlight technology. One example is Cadillac Lyriq EV in which GM plans to use a 33-inch mini LED backlit display in 2022.
In November 2021, Mecha Dragon, the first model of SL, a high-end brand of Great Wall Motor made a debut at Auto Guangzhou. The Mini-LED external display technology at the rear of this model enables display of user-defined content, the first attempt to apply Mini-LED in cars.
Automotive displays head in the direction of large size and multi-screen integration, and the surging demand creates huge room to grow. Various suppliers are therefore trying hard to deploy innovative technologies such as Mini LED and Micro LED.
Tianma Microelectronics: in 2020 it first outran JDI and became the world’s largest vehicle display company in terms of shipments. The company supplies through Tier1s, covering 92% of global customers (top 24 Tier1s) and 100% of Chinese brands (top 10).
Tianma Microelectronics works to deploy Mini LED and Micro LED technologies. Following the on-site exhibition of its self-developed LTPS AM Mini LED HDR display at annual meeting of Society for Information Display (SID) early in 2019, the company showcased its Micro LED technologies online at SID 2021, including 5.04" Splitting ultra-narrow bezel Micro LED, the world’s first 7.56" transparent Micro LED, and innovative technology applications combined with electronic paper.
Moreover, its self-developed Hybrid TFT Display (HTD) technology is in the phase of verification for mass production. The company has deployed HTD on its flexible AMOLED production lines, and will achieve mass production based on the advanced drive and backplane technologies with lower power consumption.
HGC Lighting Solutions: the new-generation white light Mini LED vehicle backlight display module features automotive-grade reliability, ultra-thin display body, multi-zone dynamic control, and million-level ultra-high contrast.
