July 2, 2012 — Liquid crystal display (LCD) panel makers have added new display features — high color gamut, 3D, LED backlight, slim type, ultra-slim bezel, 120 Hz/240 Hz/480 Hz frame rate driving, fast response time, high brightness — with varying success in driving TV demand.

Instead of “spec up,” more and more end users are looking to “spec down” for budgetary reasons. Lower but acceptable panel brightness now prevails, as it helps to reduce backlight cost. Meanwhile, as analyzed in the May 09, 2012 DisplaySearch Monitor article “Direct LED TV Selling Better than Edge LED TV,” the cost effective direct type LED-backlight LCD TV is doing well in sell-through results. While its form factor is not slim, some end users care more about how an ultra-slim bezel looks from the front.

For all these reasons, LCD TV panel and set makers are wondering what new features will add value for end users and motivate another replacement cycle.

Many people believe that ultra-high 3840 × 2160 definition (UHD or UD), also known as 4K×2K, will be a meaningful value-added feature on next-generation TV displays. 4K×2K has 4x as many pixels as full high definition (FHD, 1920 × 1080), which is the current prevailing resolution for LCD TV panels.

Smart phones and tablet PCs prove that the higher the resolution, the better for end users. These very high definition devices set consumer expectations for televisions. Because LCD TVs are still mainly used for watching rather than interaction or content creation, consumers will perceive very high resolution as a direct benefit to viewing, unlike other new features (such as smart, connected, or 3D TV and LED backlights).

The best quality video is recognized as vivid with no difference between reality and screen, and the higher the resolution, the more vivid the content. 3D technology halves resolution on LCD TVs. On 4K×2K LCD TVs, the impact of the downgrade in resolution when watching 3D content is not as severe. With 4K×2K, even after the 3D downgrade, the resolution is full HD, falling from 3840 × 2160 to 1920 × 1080.

For ultra-large LCD TVs, such as 60-80”, pixels are so big that they are visible in FHD. Therefore 4K×2K is recognized as necessary on very large TVs.

Most panel makers are implementing oxide thin-film transistor (TFT) manufacturing for 4K×2K resolution. Because of the higher electron mobility of oxide, it’s easier to design with a smaller pixel; therefore more pixels can be implanted onto the glass substrate. However, the oxide TFT process requires a 6-8 photomask process, compared to the 4-5 photomask process for amorphous silicon (a-Si) TFT. This will affect fab capacity. Chimei Innolux is planning to use a-Si TFT, rather than oxide TFT. In theory, this is workable and Chimei Innolux can save lots of surplus cost for new photomasks and maintain a better yield rate.

4K×2K LCD TV panels are a big challenge for TFT LCD process yield rate and stability. In the current TFT LCD process, the yield rate and reliability of HD and FHD do differ much. However, when the pixel count quadruples, the yield rate will fall significantly. Meanwhile, the higher resolution means panel transmittance will be reduced because there are more pixels on the substrate. As analyzed in the TFT LCD Process Roadmap Report, there are many new technologies needed for this kind of ultra-high definition:

The EE (electronics engineering) panel design: data/scan driving, input format compatibility, and value-added features including 4K up-conversion, 3D, and local dimming backlight.

The market outlook for 4K×2K is still unclear due to TV broadcasting bandwidth limitations. Despite this, LCD TV panel makers have developed many 4K×2K panels.

AUO is currently the only panel maker that has commercialized a 4K×2K product. The product is a 55” 4K×2K LCD TV with glasses-free 3D and a powerful video driving engine (Toshiba’s REGZA), shown below.

There’s also a face tracking feature, which should assist users who choose to video chat in high resolution. It’s said that LGE and Vizio are also interested in launching a 4K×2K LCD TV in the North America market later this year.

Sharp is focusing on 4K×2K and calling it Super Hi-Vision, as analyzed in the May 10, 2012 DisplaySearch Monitor article “Sharp’s Leading TV Panel Technologies.”

Content is also an issue for 4K×2K TVs. At the DisplaySearch China Smart TV & Smart Display Conference, Chimei Innolux used a slide to illustrate the current 4K×2K ecosystem status (shown below).

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.

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.

In-plane switching was developed by Hitachi Ltd. in 1996 to improve on the poor viewing angle and the poor color reproduction of TN panels at that time.

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.

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.

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.
