Abstract: A display device includes a display panel, a source driving part, a gate driving part, a readout part and a pulse generating part. The display panel includes an array substrate on which a source line and a gate line are formed, and an opposite substrate on which a common electrode is formed. The readout part is electrically connected with at least one of the lines of the array substrate and the common electrode of the opposite substrate, and reads out a detection signal during an elimination period of a frame period. The pulse generating part outputs a control pulse for driving the readout part during the elimination period. Accordingly, a detection signal is read out through lines or a common electrode that are/is formed for displaying an image, so that an aperture ratio may be increased, and a manufacturing process thereof may be simplified.

Abstract: An organic light emitting device includes an organic light emitting element and a sensor. The organic light emitting element includes an organic layer between an anode and cathode. The sensor detects a quality that provides an indication of the degradation of the organic layer of the light emitting element. The sensor may be a chemical sensor or another type of sensor. The sensor may be fixed permanently within or outside the light emitting element, and electronic measures may be taken to reduce performance loss as a result of the detected degradation of the organic layer.
