Universal Display (UDC) logoUniversal Display Corporation today unveiled a new, deep red PHOLED material at the Society for Information Display's (SID) 2007 International Symposium, Seminar and Exhibition in Long Beach, California. The Company's continued advances in high-efficiency PHOLED materials and technology are leading the way for the next generation of OLED displays for TV's and other demanding product applications.

To specify chromaticity of the three primary colors in a display, two color space standards are commonly used. They are the National Television Standards Committee (NTSC) standard, originally developed for televisions, and the more recent s-RGB color space standard established for monitors, printers and the Internet. UDC-RD26 is designed to match the deep red, NTSC chromaticity standard, while UDC-RD39 meets the bright red, s-RGB specification. Depending on the specific display application, manufacturers may prefer either a deep red color or a brighter red color with higher intrinsic luminous efficiency.

Universal Display's new UDC-RD26, with CIE coordinates of (0.67, 0.33) can operate at a luminous efficiency of 19 candelas per Ampere (cd/A), corresponding to an 18% external quantum efficiency, at 1,000 candelas per square meter (cd/m2). Under accelerated testing conditions, UDC-RD26 demonstrates an operating lifetime of approximately 90,000 hours, at an initial luminance of 1,000 cd/m2. These performance gains are significant, representing an 80% increase in luminous efficiency and 10% increase in lifetime, as compared to Universal Display's first-generation commercial deep red PHOLED emitter. In addition, both new second-generation materials are specifically designed for use in high-volume production environments.
