PHOLED (phosphorescent organic light-emitting device) is a proprietary display technology developed by the Universal Display Corporation (UDC) that uses soluble phosphorescent small molecule materials to create organic light-emitting devices ( OLED s). PHOLED technology works on the principle that certain organic molecules emit light when an electric current is applied.
Although PHOLED was originally developed as a display technology for use in mobile phones, the U.S. Department of Energy awarded UDC $200,000 in contracts to develop PHOLED products for general lighting applications. In the United States, approximately 20% of the energy currently consumed is used to light buildings and public areas. PHOLED-based lighting sources, such as glowing walls, are expected to provide cost-effective and energy-efficient alternatives to traditional incandescent and fluorescent lighting.
