LG.Philips Develops Hair-Thin Display

The flexible screen is an active matrix organic light emitting diode display, which uses a film of organic compounds to emit light.
LG.Philips LCD on Thursday said it has developed a full-color, 4-inch display that's barely thicker than a human hair.

The flexible screen is an active matrix organic light emitting diode (OLED) display, which uses a film of organic compounds to emit light. LEDs do not require a backlight, which is considered a big advantage over current liquid crystal display technology.

The LG.Philips screen can reproduce 16.77 million colors in a high-quality image, the company said. "Although we are still in the initial stages with this technology, we expect to make some exciting advances in the near future," Hyunhe Ha, executive VP and the head of the small and medium displays business unit at LG.Philips, said in a statement.

OLED is seen as an "optimal technology" for use in flexible screens, the company said. In addition, LG.Philips can use its existing production line for the displays, a major step toward demonstrating the commercial viability of the product. LG.Philips also makes thin-film transistor liquid crystal displays.

The company plans to unveil a full-color flexible active-matrix OLED -- also called AMOLED -- at The Society For Information Display conference in Long Beach, Calif., next week.

LG.Philips also introduced this month a 14.1-inch color e-paper display that uses electronic ink from E-Ink to produce a maximum of 4,096 colors. The display can be bent almost in half without affecting the image.
