LG.Philips first full-color flexible active matrix organic light emitting diode display


LG.Philips LCD has developed the first full-color flexible active matrix organic light emitting diode (AMOLED) display that uses amorphous silicon (a-Si) technology. LG.Philips LCD developed this display in cooperation with Universal Display Corporation of the United States, which holds the original patents for Phosphorescent OLED (PHOLED) technology.LG.Philips LCD’s 4-inch full-color flexible AMOLED display features 320 x 240 QVGA resolution and can reproduce 16.77 million colors. At an ultra thin 150 μm, this display is barely thicker than a human hair. It uses a stainless metal foil substrate to ensure durability and protection against heat, which improves the manufacturing process and enhances product stability.


OLED technology is recognized as an optimal technology for use in flexible displays. Using a-Si backplane technology allows LG.Philips LCD to use its existing TFT-LCD production line for these AMOLEDs, a major step toward demonstrating the commercial viability of such products. LG.Philips LCD is the first company to employ this technology. LG.Philips LCD will unveil the full-color flexible AMOLED display at SID 2007 in Long Beach, California, on May 20.
