40-inch OLED goes on display

Samsung Electronics has developed the world's first single-sheet, 40-inch active-matrix (AM) organic light-emitting diode (OLED) display for flat-panel TV applications.

The high-definition-compatible OLED prototype has a wide-screen pixel format of 1280x800 (WXGA) driven by an amorphous silicon (a-Si) AM backplane to permit faster video response times with low power consumption.

Samsung's 40-inch OLED panel was demonstrated for the first time at the Society for Information Display (SID) 2005 International Symposium, Seminar, and Exhibition in Boston in May.

Shattering traditional AMOLED size limitations, the new prototype offers a black-and-white contrast ratio of 5000:1 and a colour gamut of 80 percent of the NTSC standard. The thin panels will allow TV set designers to create televisions with a total thickness of only 3 cm or less.

"Our development of a 40-inch OLED will provide a firm basis from which we can become the market leader in the flat panel display market of the future," said Dr. Kyuha Chung, vice president of the Samsung Electronics LCD R&D Center.
