fhd lcd panel manufacturer

In both LCD and OLED displays, producing these cells – which are highly complex – is by far the most difficult element of the production process. Indeed, the complexity of these cells, combined with the levels of investment needed to achieve expertise in their production, explains why there are less than 30 companies in the whole world that can produce them. China, for instance, has invested more than 300 billion yuan (approximately $45 billion USD) in just one of these companies – BOE – over the past 14 years.

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.”

Coding/De-Coding Standard: H264 seems to be sufficient for 4K×2K. The new generation H265 will be ready by 2013. At the same time, enhancing compression will further reduce the bottleneck of 4K×2K signal transmission. Also, there are some up-scaling solutions to convert HD and FHD signals to 4K, such as QDEO.
