LG Philips claims largest organic LED display

A 20.1 inch active matrix OLED display was shown in Japan on Tuesday

LG Philips is developing what the company claims is the world's largest organic light emitting diode (OLED) display.

The company, which manufactures TFT-LCD screens at factories in South Korea, unveiled a prototype 20.1inch active matrix OLED display at the FPD International trade show in Japan on Tuesday.

It is based on 'low temperature polysilicon', a technique also used in TFT-LCD production where active components are integrated across the display glass. This lets the OLED display be made using modifications of existing techniques and production lines. Because OLED displays do not need a separate backlight, the power consumption of the finished unit will be lower than that of its LCD counterpart.

LG Philips wasn't able to provide full technical details of the device at the time of writing, but according to reports, the OLED display contains three million pixels, suggesting has a resolution of 2028x1536.

Until now, Samsung had the honour of having created the largest OLED display. In May it announced a 17-inch active matrix OLED display with a resolution of 1600x1200.

Other companies have announced OLED displays that are larger than 20.1 inch, but these have actually contained a number of smaller units stuck together.

Kodak has also shown plenty of interest in OLED.
