SEOUL, South Korea Display maker Samsung SDI Co., Ltd. unveiled Thursday (May 17) what it claimed is the world's thinnest active-matrix organic light emitting diode (AM-OLED) display module for mobile phones. The display uses low-temperature polysilicon technology.
Samsung SDI said its 0.52-mm-thin, 2.2-inch AM-OLED module approaches the dimensions of a 1.7-mm TFT-LCD module considered to be the slimmest among the existing LCD modules available for mass production.
"We plan to mass produce the new AM-OLED module during the third quarter of this year," said Yoo Eui-Jin, vice president of AM-OLED Business at Samsung SDI. He added that Samsung SDI is "completely ready now" to begin volume production of the new module once orders are received.
The new module, developed using Samsung's proprietary "module slimming" technology, features QVGA (240 by 320) resolution and a 10,000:1 contrast ratio.
A Samsung SDI spokesman said display module power consumption, on average, is as much as 40 percent less than the existing TFT-LCDs.
Samsung expects to produce about 15 million AM-OLED modules per month for a wide range of handset displays, according to Yoo.
LG.Philips joins race
LG.Philips LCD, Samsung SDI's AM-OLED rival, has meanwhile claimed the world's first full-color, flexible AM-OLED display based on amorphous silicon technology. LG.Philips said it developed the new display in cooperation with Universal Display Corp. (Ewing, N.J.), which holds the original patents for phosphorescent OLED technology.
The LG.Philips LCD's 4-inch AM-OLED display features QVGA resolution and can reproduce 16.77 million colors. With a thickness of 150 microns, the new display uses a stainless metal foil substrate to improve durability and protection against heat.
LG.Philips said it will unveil the color AM-OLED display at SID 2007 next week (May 20) in Long Beach, Calif.
