The company has followed new approaches for LTPS, such as the Super Grain Silicon (SGS) technology that allowed the company to succeed in the development of such a large OLED display. In addition, the "Super MicroCavity Bottom Emission" structure technology has enabled a color gamut of 107% NTSC.
Samsung also had on display a 31" Full HD OLED as well as smaller 14" 1,366x768 models, all featuring a , and a contrast ratio of 1,000,000:1 and a brightness of 200 cd/m2. Samsung has not disclosed when these prototypes will enter mass production.
Another interesting product was what the S.Korean company calls "flapping display". It is a paper-thick (0.05mm) OLED display that was can be hung in the air as an A4 paper page. The 4" display has 480 ? 272 pixels, a contrast ratio of 100,000:1, and the luminance of 200cd/m2. The color reproduction range is 100% of the NTSC standard.
A semi-transparent OLED panel was also in display. The 4.82" panel has a transmittance of 30%, a resolution of 840 ?504, and its luminance is 200cd/m2. The response time is 0.01ms.
Samsung also showcased an ultra fine Definition 63" (4096 ? 2160) PDP panel. In order to achieve such a high resolution, the plasma display has pixels sized at just 0.339 x 0.363mm.
CMEL's millimeter-thick OLED panel
Taiwanese Chi Mei EL has also developed a 25-inch OLED screen that's less than a millimeter thick.
The new screen has a resolution of 1,366 pixels by 768 pixels (WXGA) and can display 16.7 million colors. Its contrast ratio is 10,000:1.
Chi Mei EL is a display offshoot from Taiwan's Chi Mei Optoelectronics.
