Abstract
A white light generating organic electroluminescent device including an organic light emitting diode emitting a broad spectrum light including a component of each primary color. A multi-mode microcavity structure is positioned to cooperate with the diode defining an optical length of the microcavity structure to enhance the broad spectrum light and obtain multiple resonant peaks, one at each primary color. A plurality of filters are positioned to receive and adjust the multiple resonant peaks to provide substantially balanced multiple resonant peaks.
