Universal Display Corporation (UDC) has unveiled its latest UniversalPHOLED technology and materials for energy-efficient displays and lighting at the Society for Information Display (SID) International Symposium 2010.

Universal Display also reported advances in performance of its white OLED on a commercial-scale 15 cm x 15 cm lighting panel using its efficient phosphorescent OLED technology and materials.

The panel emits a warm-white light with a color rendering index (CRI) of 87 and a correlated color temperature (CCT) of 3055K. It also has a luminous efficacy of 50 lumens per Watt using an optical outcoupling treatment with a modest 1.5x enhancement factor. With an operating lifetime of approximately 10,000 hours to 70% of an initial luminance of 1,000 cd/m(2).

To achieve these results, the company employed a new light-blue UniversalPHOLED emitter system, which helped extend its operational lifetime and improve its emission color stability with aging. The light-blue emitter system was added to the company's red and green UniversalPHOLED for white lighting.
