Abstract
An organic light emitting display includes an organic light emitting diode formed on a substrate, coupled to a transistor; a photodiode formed on the substrate and including a semiconductor layer including a high-concentration P doping region, an intrinsic region with defects and a high-concentration N doping region; and a controller that uniformly controls the luminance of light emitted from the organic light emitting diode by controlling a voltage applied to the first electrode and the second electrode according to the voltage outputted from the photodiode.
Claims3
An organic light emitting display, comprising:
- an organic light emitting diode coupled to a transistor and including a first electrode, an organic thin film layer and a second electrode;
- a photodiode formed on a substrate and comprising a semiconductor layer including a high-concentration P doping region, an intrinsic region with defects and a high-concentration N doping region;
- a reflective layer formed between an upper surface of the substrate and a lower surface of the photodiode that reflects light incident from an exterior of the organic light emitting diode onto the photodiode
- an interlayer insulator formed on the photodiode;
- a light receiver formed on the intrinsic region by etching a region of the interlayer insulator and exposing the intrinsic region.
