LG Plans to Show First 55-inch OLED HDTV at CES 2012

Many TV makers have promised OLED HDTVs as next generation technology since 2007. However, very high cost of production of OLED screens bigger than 10-inch has kept TVs based on OLED technology an item for trade show floors rather than mass market. But LG promises to change that with their newly developed 55-inch OLED TV panel, which they will show to select media and customers at a private booth starting on January 9 in Las Vegas through the end of CES 2012.

According to LG, the world’s first 55-inch OLED TV panel will demonstrate the effective application of AM OLED technology to larger panel sizes at a more cost efficient level. The LG 55-inch OLED TV is just 5mm (0.19-inch) thick and offering 100,000:1 contrast ratio, with wider color gamut and 1000 times faster switching than LCD screens.

"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."

LG was able to achieve lower cost and improved performance by adopting Oxide TFT technology in place of Low Temperature Poly Silicon (LTPS) and White OLED (WOLED). In Oxide TFT technology, Amorphous Silicon found in LTPS TFT is replaced with Oxide, which is cheaper and offers image quality identical to high performance LTPS TFT. Also, by using the White OLED that vertically accumulates red, green and blue diodes offering lower error rate, LG got higher productivity, and a clearer Ultra Definition screen via the benefits of small pixels.

In past few years there have been many promising developments in OLED manufacturing using direct printing technology for large displays, but this is the first time that an OLED technology looks ready for the TV market. LG didn’t say when they will ship the 55-inch OLED TV, which we don’t think will happen in 2012. However, we believe that smaller OLED TVs (say 32-inch to 40-inch) based on the new technology should come to the market this year in limited quantities.
