Abstract
An organic light emitting element includes an organic light emitting diode formed on a substrate, coupled to a transistor including a gate, a source and a drain and including a first electrode, an organic thin film layer and a second electrode; a photo diode formed on the substrate and having a semiconductor layer including a high-concentration P doping region, a low-concentration P doping region, an intrinsic region and a high-concentration N doping region; and a controller that controls luminance of light emitted from the organic light emitting diode, to a constant level by controlling a voltage applied to the first electrode and the second electrode according to the voltage outputted from the photo diode.
