Flexible OLED screen to be shown

Display could be used in new form factors, say co-inventors

Ewing, N.J. — Universal Display Corp. and LG.Philips LCD Co. will show prototype of their flexible, full-color, active-matrix organic light emitting diode (AMOLED) display at this week’s Society for Information Display Conference and Symposium in Long Beach, Calif.

The companies said they believe the 4-inch QVGA display is the first high-resolution AMOLED built on flexible metal foil using amorphous-Silicon (a-Si) backplane technology.

Said to offer crisp, full-color video images, this display combines LPL’s a-Si backplane technology adapted to metal foil with Universal Display’s proprietary high-efficiency PHOLED and FOLED flexible technologies.

The foil prototype, with its extremely thin, lightweight and rugged form factor, represents a major step toward the demonstration of the commercial viability of such products, the companies said.

This demonstration is also important in that it provides further evidence that highly-efficient PHOLED technology may enable the use of a-Si backplane technology for AMOLEDs.

While many in the industry have focused on the value that poly-Silicon technology would bring to AMOLEDs, a much larger a-Si TFT manufacturing base and lower cost structure make a-Si technology an extremely attractive backplane option for AMOLEDs.

Flexible OLEDs could be used to create new form factors such as a wrist-based PDA, the companies said.
