FEATURES AND PERFORMANCE
Our patented UniversalPHOLED® phosphorescent OLED (PHOLED) technology and award-winning materials are integral to enabling low power consumption in OLED displays and lighting. With luminous efficiencies that are up to four times higher than with fluorescent OLED materials, PHOLEDs also reduce heat generation and enhance the number of AMOLED backplane choices. These important PHOLED advantages allow OLEDs to compete with LCDs and conventional light sources.
Universal Display continues to demonstrate advances in its UniversalPHOLED technology and materials. As shown below, we unveiled advances in luminous efficiency and operating lifetime for a number of our color systems at SID 2012.
Today, our reds and greens offer extremely long lifetimes under a variety of operating conditions, and our blues continue to improve toward commercial entry targets. Our enhanced light-blue phosphorescent OLED emitter system with a 2x improvement in lifetime offers the potential for significantly reduced power consumption and extended operational lifetime in OLED devices for both display and lighting applications. For lighting applications, it may accelerate the introduction of a variety of initial commercial products where high-efficacy, warm-white emission is important. The new system also offers key performance advances for displays when used in Universal Display’s new four sub-pixel format.
PHOLED technology and materials are well suited for use in a variety of manufacturing processes. A number of our PHOLED materials have been tested on commercial vacuum thermal evaporation (VTE) manufacturing equipment - demonstrating the extended cycle times needed for high-volume production. PHOLEDs are also compatible with OVPD™ organic vapor phase deposition, laser induced thermal imaging (LITI) and other novel deposition/patterning techniques, including ink jet printing, currently under development.
PHOLEDs may be an excellent "green" solution for displays and lighting. With increased energy efficiency, PHOLEDs can reduce the demand for electricity and non-renewable fossil fuels. Also, OLEDs may significantly reduce the waste and disposal issues commonly associated with CRTs and fluorescent tubes.
