The OLED technology seems to be moving the the right direction faster and faster every month. The main factor limiting OLED HDTV production is their size limits, with the only available screens being very small.
Samsung has just changed this. They have shown off the world’s largest, 40-inch OLED panel HDTV with a full HD resolution of 1920 x 1080 pixels at the FPD International. This OLED HDTV has a native (we assume) contrast ratio of a massive 1,000,000:1, 107% NTSC color gamut, and luminance of 200cd/m2 and a peak of 600cd/m2.
“Our low temperature poly-Si TFT mass-production line cannot make panels larger than 31 inches,” a Samsung staffer said. “This 40-inch TFT panel is the largest size that can be made on our pilot line, and it cannot be mass-produced right away.” The RGB organic light emitting materials were formed by vapor deposition. The company used a fine metal mask (FMM). Fluorescent materials are used for red and green, while a phosphorescent material is used for blue, the staffer said.
The main thing to learn from this is; OLED HDTVs are on their way! It will still be some time yet, but more manufactures are getting in on the action, and producing larger panels with HD resolution , which can be used for HDTVs. News Source
