LG to unveil 55-inch OLED TV

LG Display has announced that it has developed the world's largest 55-inch OLED (Organic Light Emitting Diodes) TV panel.

Boasting of a high image quality in an ultra-thin design, LG claims that the 55" OLED TV panel produces remarkable image quality with no after image due to its high reaction velocity, as well as high contrast ratio of over 100,000:1.

The 55" OLED TV panel will be displayed at the Consumer Electronics Show (CES) scheduled to be held on January 9 in Las Vegas.

"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."

OLED, a medium that controls pixels is a departure from LCD panels which utilize liquid crystals. 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 OLED panel allows diodes to be turned on or off which enables lower power consumption than conventional LCD panels.

According to LG, 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.

Although industry watchers anticipate OLED as the future of TV display, the technology has faced challenges due to limitations on the sizes of displays it can be applied to and a high level of investment required.
