ORGANIC LIGHT EMITTING DIODE DISPLAY WITH PHOTOSENSOR FOR SENSING LIGHT GENERATED BY LIGHT EMITTING LAYER

摘要

PURPOSE: An organic light emitting diode display is provided to calculate volume of light transmission while maximizing light emission of the display. CONSTITUTION: An organic light emitting diode display comprises a transparent electrode(30); a reflective electrode(18) having a transparent window(29); a light emitting layer interposed between the transparent electrode and the reflective electrode; and a photosensor(13) arranged underneath the transparent window of the reflective electrode, in such a manner that the photosensor senses light generated by the light emitting layer.
