LG Electronics has just confirmed to SmartHouse that they will launch a new 55″, 5mm OLED TV at the 2012 CES Show, executives at the Korean Company claim that OLED is the future for flat panel display screens.
Claiming the 55-inch panel is a significant step forward LG engineers said the new TV will be more cost efficient to run and will use white OLEDs overlaid with colours, which makes for a lower error rate and clearer “ultra definition” screen, with more colours than standard LCDs.
The OLED Screen has a contrast ratio of over 100,000:1 and wider colour gamut than that produced by LCD panels.
“Our objective has always been to actively define and lead emerging display technology markets,” said Dr. Sang Beom Han, CEO and Executive Vice President of LG Display. “Although OLED technology is seen as the future of TV display, the technology has been limited to smaller display sizes and by high costs, until now. LG Display’s 55-inch OLED TV panel has overcome these barriers.”

The new technology allows light emitting diodes to self-generate light and features a reaction velocity to electric signals over 1000 times faster than liquid crystal.
The panel adopts an Oxide TFT technology for backplane which is different from a Low Temperature Poly Silicon (LTPS) type generally used in existing small-sized OLED panels. The Oxide TFT type that LG Display utilizes is similar to the existing TFT process, with the simple difference lying in replacing Amorphous Silicon with Oxide. Moreover, the Oxide TFT type produces identical image quality to high performance of LTPS base panels at significantly reduced investment levels.

Additionally, LG Display uses White OLED (WOLED). WOLED vertically accumulates red, green, and blue diodes. With white colour light emitting from the diode, it displays screen information through colour layers below the TFT base panel, which leads to a lower error rate, higher productivity, and a clearer Ultra Definition screen via the benefits of small pixels. Further, it is possible to realize identical colours in diverse angles via colour information displayed through a thin layer. Lower electricity consumption in web browsing environments for smart TVs is another key strength of WOLED.
