A light emitting device with adaptive intensity control. In a particular embodiment, there is an active display pixel providing a light. At least a portion of the provided light is incident upon a photodetector optically coupled to the display pixel, the photodetector providing an electrical feedback signal in response to the light. A feedback controlled intensity controller electrically coupled to the photodetector and an electrical switch coupled to the active display pixel are also provided. The feedback controlled intensity controller further receives an electrical reference signal. The feedback controlled intensity controller opens and closes the switch depending upon the relationship of the feedback signal to the reference signal.
