Samsung 31-inch OLED
Samsung's SDI division on Thursday morning announced that it had developed a 31-inch TV using active matrix organic LED (AMOLED) technology. The screen is the largest to ever have been completed, eclipsing a 27-inch Sony OLED demonstrated early this year. As OLEDs need no separate backlight, the Samsung set measures just 4.3mm (0.17 inches) deep -- a tenth of the size of a contemporary LCD display, Samsung boasts. Nonetheless, the technology also has a far better contrast ratio than typical flat-panel displays and consumes half the power of a 32-inch LCD.
While still in the early stages, the new set is rated at 35,000 hours of useful life, enough for it to run for four years non-stop and the longest of any AMOLED screen. Samsung has not announced any immediate plans to produce the set, saying that it will depend on whether other firms are interested, but says it will have a 14-inch display on the market by 2008 and that companies beyond Samsung itself have expressed interest in using the smaller screen.
