Sony and UDC to develop OLED displays (Opto News)
Universal Display Corporation (UDC) and Sony will jointly develop high-efficiency active matrix organic LED (OLED) displays for use in large-area monitors. UDC, a manufacturer of organic LEDs based in Ewing, New Jersey, will combine its high-efficiency electro-phosphorescent materials with Sony s low-temperature polysilicon active matrix OLED technology. Using this combination, Sony recently produced a 13 inch diagonal display consisting of 800 600 pixels. The company says the display is slightly thicker than a credit card and has the potential to replace bulky cathode ray tubes (see ). Organic LED sources offer several advantages over liquid crystal displays (LCDs): OLEDs are self-luminous, which allows a wide viewing angle and high contrast ratio, in addition to precise color reproduction. "We believe that Sony s vision of a thin, lightweight OLED television monitor is a dramatic confirmation of the essential attributes of OLED technology," said UDC s president and COO, Steven Abramson. "UDC and their research partners have been developing innovative OLED technologies for more than seven years," added Tetsuo Urabe, Sony s general manager of OLED development. "The combination of Sony s advanced active matrix-OLED technology and UDC s expertise in OLED R&D will accelerate the realization of this revolutionary flat panel display technology for large area applications."
