The main message from Samsung at the FPD International is that the 40-inch OLED Panel is the Largest Size Possible.

Samsung SDI exhibited a 40-inch OLED panel that features a full HD resolution of 1920 x 1080, a contrast ratio of 1,000,000:1, a color gamut of 107% NTSC and a luminance of 200cd/m2 (peak luminance 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.
