LG Display Unveils World's Largest OLED TV Panel
The company will show off what it claims is the world's largest OLED HDTV panel at the 2012 Consumer Electronics Show.LG Display, a manufacturer of thin-film transistor LCD technology, announced that it has developed what it calls the world's largest organic LED TV panel, measuring 55 inches and just 5 millimeters thin. The company will showcase the TV at this year's Consumer Electronics Show in Las Vegas in January. The OLED, a medium that controls pixels, is a departure from LCD panels, which use liquid crystals. The new technology allows LEDs to self-generate light, and features a reaction velocity to electric signals over 1,000 times faster than LCDs.
The panel adopts an oxide TFT technology for backplane, which is different from the low-temperature polysilicon (LTPS) type generally used in existing small-sized OLED panels. The oxide TFT type that LG Display uses is similar to the existing TFT process, with the difference lying in replacing amorphous silicon with oxide. Moreover, the oxide TFT type produces identical image quality to high-performance LTPS base panels at reduced investment levels. OLED panels also allow diodes to be turned on or off, which enables lower power consumption than conventional LCD panels.
