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.
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.
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.

China"s first 8.5-generation TFT-LCD production line was launched in Bengbu, East China"s Anhui province, on June 18, 2019, representing a breakthrough in the production of high-definition LCD screen, Science and Technology Daily reported.
TFT-LCD, or Thin Film Transistor Liquid Crystal Display, is key strategic material of the electronic information display industry. The Gen 8.5 TFT-LCD production line, launched by the Bengbu Glass Industry Design and Research Institute of the China National Building Material Group, will produce high-definition LCD screens of 55 inches, the report said.
According to the Liquid Crystal Branch of the China Optics and Optoelectronics Manufactures Association, the demand for TFT-LCD in the Chinese mainland was about 260 million square meters in 2018, including 233 million square meters" Gen 8.5 TFT-LCD. However, the annual supply of domestically made TFT-LCD is less than 40 million square meters, with all of them Gen 6 or below, which cannot meet the demand in scale and quantity.
The association predicted that China"s market demand for Gen 8.5 TFT-LCD or above will exceed 300 million square meters by 2020, accounting for 49.6 percent of the total global demand.
The production and control precision of Gen 8.5 TFT-LCD is comparable to that of the semiconductor industry, representing a higher level of large-scale manufacturing of modern glass industry.
The institute in Bengbu, with 60 years of expertise in glass, has finally made a breakthrough in the production of Gen 8.5 TFT-LCD, and will provide key raw material guarantee for China"s LCD panel industry after it goes into mass production in September, the report said.

(Yicai Global) June 19 -- China National Building Material has built the country"s first production line capable of producing 8.5th-generation TFT-LCD glass substrates, making China one of few nations to master the technology.
The central state-owned firm"s Bengbu Glass Industry Design and Research built the facility after three years of research, Science and Technology Daily reported. The plant aims to obtain certifications that will allow it to manufacture for domestic display makers.
TFT-LCD, or thin-film-transistor liquid-crystal displays, are classified by the size of their glass substrate. Sixth-generation displays are now widely considered out-dated while 8.5th-gen tech is the most advanced. The newer technologies use larger substrates, which are more efficient to make and can be used in larger screens.
In ruling NY N320557 (August 4, 2021), Customs and Border Protection (CBP) discussed the country of origin of five Thin Film Transistor – Liquid Crystal Display (TFT-LCD) modules. All five modules are virtually identical in composition, as they are all composed of a TFT-LCD cell, polarizers, a backlight, a driver and control printed circuit board (PCB), and a flexible PCB for connection. TFT display technology allows for the construction of high-resolution LCD displays, and the modules – once completed – can be incorporated into a variety of consumers display applications.
The manufacturing process for the five modules is also identical. The process begins in Japan where the TFT-LCD cell is manufactured. The TFT is created by depositing transistors onto a substrate through chemical vapor deposition, while the color filter is manufactured by building a color matrix on a glass substrate. The creation process of the cells is then completed when a layer of liquid crystal is deposited between the color filter and TFT as the two part are bonded together, creating a sheet of TFT-LCD cells. As next steps, the sheet of cells is delivered to China to be cut into individual cells. The cut-up cells are then bonded to the printed circuit board assembly (PCBA) – which contains the driver and control circuity – before the polarizers, backlight, and flexible connection PCBA are attached.
CBP also established that “substantial transformation” takes place when a particular product “emerges from a process with a new name, character or use different from that possessed by the article prior to processing.” The agency explained that the completed TFT-LCD cell is what imparts the essential function of the module and that the manufacturing process in Japan is what renders the end-use of the product. Despite the assembly that took place in China, the process did not substantially transform the cell into a new and different article. As such, CBP determined that the country of origin of the five modules is Japan.
SHANGHAI, Aug 26 (Reuters) - China"s BOE Technology Groupwill soon start building the country"s first eighth generation TFT-LCD (thin-film transistor liquid crystal display) production line with an investment of 28 billion yuan ($4.1 billion), a source close to the situation said on Wednesday.

The short name of TFT:Thin Film Transistor in Chinese. What is the difference between TFT and LCD? Our laptops and desktops now use relatively advanced TFT displays, which consist of LCD pixels and are powered by thin-film transistors integrated behind the pixels. Therefore, the TFT type display screen also belongs to a class of display devices with a source matrix.
TFT type display screen is currently a better LCD color display, TFT type display has many advantages: high responsiveness, high brightness, high contrast, and so on.TFT displays are closest to CRT displays. The TFT screen also often appears on the screen of each big mobile phone, there are 65536 colors, 160,000 colors, 16 million colors three, its display effect is also very good.
TFT means that every LCD pixel on an LCD is driven by a thin-film transistor integrated behind it. Thus can achieve high speed, high brightness, high contrast display screen information, TFT-LCD(thin-film transistor liquid crystal display) is one of the majority of LIQUID crystal displays.
Liquid Crystal Display (LCD). The structure of the LCD is placed in the middle of the two pieces of parallel glass liquid crystal box, the substrate glass set on TFT (thin-film transistor), set the color filter substrate glass on, on the TFT signal, and the voltage change to control the rotation direction of the liquid crystal molecules, so as to achieve control of each pixel display emergent polarized light or not and to achieve. Now THAT LCD has replaced CRT as the mainstream, the price has dropped a lot and become widely available.
The TFT(Thin Film Field-effect Transistor) is a video in which every single pixel in the liquid crystal display is actuated by a Thin Film Transistor embedded in the rear. Thus can achieve high speed, high brightness, high contrast display screen information.
Color screens of mobile phones vary depending on LCD quality and research and development technology. The types of color screens include STN (CSTN), TFT(LTPS), TFD, UFB, and OLED.
Liquid Crystal Display (LCD). Generally divided into monochrome and color LCD two kinds, the current monochrome LCD has almost out of the notebook computer market, and color LCD still continues to develop. The color LCD can be divided into two types: STN and TFT. The TFT(Thin Film Transistorized)LCD, also known as the active transistorized Transistor LIQUID crystal display (LCD), is the true-color LIQUID crystal display that many people describe as the Thin Film Transistor.DSTN (Dual Scan Twisted Nematic)LCD, namely double scan LIQUID crystal display. It is a display mode of STN LCD, which is no longer on the market.
What is the difference between TFT and LCD? Read here I believe you have a general understanding and cognition of TFT and LCD, LCD refers to liquid crystal display, TFT is a kind of LCD. The former is for laptops and the latter is for desktop computers. There are several different technologies for LCD, FED, PDP, OLED, TFT-LCD, they are all LCD. Only the desktop with several fronts more, lower cost, TFT technology cost is higher, generally used for notebook, or MOTO, etc., now most of the display is TFT type display, I believe we will pay more attention to the choice and purchase of digital goods.
RE:Country of origin; Thin Film Transistor (TFT); Liquid Crystal Display (LCD); TFT/LCD module; PCB; flat panel display computer monitor; marking; outermost container; ultimate purchaser; substantial transformation; Hitachi; Japan; China; HRL 560427; 19 CFR 134.1(a); 134.32(d).
This is in reply to your letter, dated April 8, 2002. In that letter, you requested a ruling on the country of origin marking requirements for TFT- LCD modules assembled in China of Japanese components and imported into the United States to be used to make notebook computer monitors and flat panel desktop computer monitors. Our response follows.
Hitachi will produce finished thin film transistor (TFT)/liquid crystal display (LCD) modules that will be imported into the United States. The two products at issue are: 1) TFT/LCD modules for use with notebook computers; and 2) a Super IPS (In Plane Switching) TFT-LCD module to make flat panel desktop computer monitors.
You state that although the Japanese-origin TFT-LCD Cell is the primary component, the Japanese components are substantially transformed in China when they are assembled into a TFT-LCD module in China. You contend that the components, which include the PCB, Back Light Unit (with CFL), tape, frame, cables, and the TFT-LCD Cell, when assembled result in a different commercial article, that is, a completed TFT-LCD module ready for use to manufacture notebook computer monitors or flat panel desktop computer monitors.
A representative of your company stated by telephone on April 24, 2002, that after importation of the finished TFT-LCD modules into the U.S., your company stores them in a warehouse as part of your company’s inventory. When a customer orders the modules, they are shipped to the customer. Your representative stated that because the imported articles are highly sensitive and fragile, your company does not normally repackage the imported articles. Your company’s customers then incorporate the TFT-LCD modules into a monitor when manufacturing their final computer product. In other words, the modules are not ready to be used as monitors when imported into the U.S. because they lack components such as the frame, power supply, driver, et cetera and must be further processed in the United States.
What are the country of origin marking requirements for finished TFT-LCD modules assembled in China from Japanese components and imported into the United States to be used for manufacturing notebook computer monitors and flat panel desktop computer monitors?
Based on the facts provided, it is our opinion that the assembly of various components used in producing the TFT/LCD module in China, including the Back Light Unit which is made in China from approximately 12 components, effects a substantial transformation of the individual components. The individual components, most of which are made in Japan, lose their identity and become integral part of the new article – TFT/LCD module. The assembly operations are also not minimal or simple. Thus, the TFT/LCD module as imported into the United States qualifies as a product of China and therefore should be marked as such.
In HRL 560427, the LCD module was made in Japan and imported into the U.S. The LCD module was then combined with nine other U.S. components to manufacture the final Flat Panel TFT/LCD monitor for personal computers. Customs ruled that the Japanese-origin LCD module was substantially transformed in the U.S. when incorporated into the monitor in the U.S. Similarly, in the instant case, the TFT/LCD module made in China will be incorporated in the United States into flat panel desktop computer monitors and notebook computer monitors manufactured by your customers.
In the instant case, unlike the case in 560247, the importer is not the manufacturer or the processor. However, subject to the terms of 19 C.F.R. § 134.35(a) and 19 C.F.R. § 134.1(d)(1), your company’s customers, who use the imported TFT/LCD modules to produce the flat panel desktop computer monitors and notebook computer monitors in the United States would be considered the ultimate purchasers. Therefore, as in HRL 560247, the imported article in the instant case qualifies for the marking exception provided in 19 C.F.R. § 134.35(a) and 19 C.F.R. § 134.32(d). Consequently, the country of origin marking requirements may be met in the instant case by having the imported articles’ containers (i.e. boxes or other containers that hold the modules) marked with the country of origin, assuming that those containers also reach your customers.
For the foregoing reasons and based on the facts provided, the TFT/LCD modules are products of China and therefore should be so marked. However, because the TFT/LCD modules will be used by your customers to manufacture flat panel desktop computer monitors and notebook computer monitors in the United States, your customers are the ultimate purchasers. Therefore, the marking requirements may be met by marking the containers of the imported articles with their country of origin, assuming that your customers receive the articles in those containers.

TFT display module is a Thin Film Transistor, and AMOLED is Active-matrix organic light-emitting Display. The TFT display module is backlight-on the liquid crystal panel; AMOLED is a panel that emits light on its own; TFT display module structure is more thick and strong, AMOLED is very thin and also weak, TFT display module is used widely than AMOLED, AMOLED is used in consumer products the most, like a smartwatch, mobile phone, and TV.
IPS is In-Plane Switching, It is also known as free viewing angle, which means the viewing angle of the display on 4 sides is the same, a normal display has its best viewing angle like 6 o’clock or 12 o’clock. While the TFT display module contains normal viewing angles and IPS display,IPS display is a kind of TFT display module.
TFT display module belongs to LCD, LCD is Liquid Crystal Display, it contains mono(single color) LCD and color LCD, single color LCD is barely used now, and color LCD has STN and TFT two types. Therefore, TFT display module is a kind of LCD display.
OLED is Organic Light Emitting Display, it is a display that emits light on its own, and it does not need an extra backlight, so it requests lower power consumption than TFT display module but its lifetime is shorter than TFT(5000 hours), AMOLED is a kind of OLED but it is more colorful. TFT display module requests a backlight to light on and power consumption are higher than OLED, but its lifetime is much longer(20000 hours).
The LED display is working by lighting up the LED lights, the TFT display module is lighted up by the backlight and the liquid crystal starts to work and shows contents. TFT display module has brighter and more true color, and lower price and LED display has lower power consumption, smaller heat, and longer lifetime.
Compares to other types of display, TFT display module is the more widely used, it can be made in different shapes and sizes, from very small sizes to big sizes. The resolution now is higher and higher, and the price of custom TFT display modules is more and more competitive. Its lifetime is longer than the OLED display, and its color is brighter than OLED.
