ABSTRACT:
A light emitting device is provided. The light emitting device contains an array of organic light emitting diodes (OLEDs) emitting a plurality of colors, and a layer of scattering media above the light emitting surface of the OLED array. The emission color of the OLEDs may be tuned by applying different power to different sets of OLEDs. The scattering media mixes the colors from each set of OLEDs, such that the device light output has a white color having a desired color temperature.
