Samsung SDI showcased a 40″ OLED TV with a pixel format of 1920 x 1080 at the FPD International 2008 show. According to OLED-Info, Samsung had already showed a 40″ OLED TV prototype back in 2005 however that unit didn’t have Full HD capability and having limited to just 1280 x 800. The new 40″ OLED TV prototype has a contrast ratio of 1,000,000:1, the previous prototype was limited to 5000:1. The company claims that it is the world’s first and world’s largest.
The benefits of OLED technology applied to the TV application are many: because the organic light emitting diodes are themselves a light source, an additional light source is unnecessary. LCDs require a backlight and the backlight consumes a considerable amount of energy. The backlight not only consumes the most amount of energy as a LCD component it also requires a lot of space, although there has been much advances in making it thin. OLED technology because it does not require a backlight can be made extremely thin. The contrast ratio of 1,000,000:1 is already competing against the best that PDP technology has to offer, which by the way is Pioneer‘s KURO PDPs. LCD technology can attain such high contrast ratio when incorporating a LED backlight with local dimming technology such as Sony‘s XBR8 series of LCD TVs.
