MANHASSET, NY -- LG Display has developed a 55-inch TV panel with organic light emitting diodes as a demonstration that active matrix OLED technology can be applied cost efficiently to large panel sizes.
LG Display’s 55-in. OLED TV panel produces superior image quality and a high contrast ratio of over 100,000:1 and wider color gamut than that produced by LCD panels.
OLEDs control individual pixels to self-generate light and feature a reaction velocity to electric signals over 1000 times faster than liquid crystal. The 5-mm thick OLED panel enables lower power consumption than conventional LCD panels.
“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,” said Sang Beom Han, CEO and Executive Vice President of LG Display, in a statement.
LG Display is able to achieve low fabrication costs by using oxide thin-film transistors for the panel replacing amorphous silicon. In contrast, Low Temperature Poly Silicon (LTPS) TFTs are generally used in existing small-sized OLED panels. The Oxide TFTs type produces identical image quality to high performance of LTPS base panels at significantly reduced investment levels, according to LG Display.
By using White OLEDs (WOLED) which vertically accumulates red, green, and blue diodes LG Display claims to achieve a lower error rate and a clearer resolution screen.
The 55-inch OLED TV panel will be made available for limited viewing at next month’s CES 2012 in Las Vegas.
This may be the excuse that people with 5 year old plasma's need to to upgrade their TV's. With the dramatic drop in prices this last year, it'll be interesting to see if these can be cost competitive.
Early OLED lifetime issues were related to moisture ingress, and making truly displays hermetically sealed over the long term is normally very expensive. Is Samsung's OLED process now moisture-insensitive or have they improved the sealing?
I would be interested to hear more...
