OLED development reduces heat compared to fluorescent lighting

Under a program funded by the DoE, titled "Thermal Management of High-Efficacy White Phosphorescent Organic Light Emitting Devices," Universal Display will design and build white PHOLED lighting panels to evaluate the impact of operating temperature on performance.
The adoption of this technology would dramatically reduce the amount of heat generated during panel operation compared to conventional fluorescent lighting. However, operating at high brightness levels and over large areas may, still lead to small increases in the operating temperature of a panel.
By effectively managing the relatively small amount of heat that is generated, the Company believes that it may further enhance OLED lighting performance, especially operating lifetime at the high luminance levels and with the large-area sizes required for general illumination. Universal Display will use 6" x 6" panels in the first step towards understanding these issues.
The outcome of this study may also lead to novel thermal management technologies for OLEDs.
According to industry estimates, electric bills for lighting alone are over $200 billion per year globally. It has been estimated that by 2016, white OLEDs could generate well over$ 20 billion in worldwide savings of electricity costs and could save over nine million metric tons of carbon emissions from the U.S. alone.
