ORGANIC LIGHT EMITTING DISPLAY AND DRIVING METHOD THEREOF

摘要

An organic light emitting display and driving method thereof is provided to indicate the image of the uniform luminance regardless of the deterioration of the OLED(organic light emitting diode) and threshold voltage / mobility of the driving transistor. An organic light emitting display comprises a plurality of pixels(140`), a sensing part, a transform unit and a data driver. The plurality of pixels is located at the intersection of data lines(D1~Dm), the scanning lines(S1~Sm) and the luminous control lines(E1~Em). The sensing part senses the deterioration information of the OLED equipped in each pixels and the information for the movement of the driving transistor. The transform unit converts input data into calibration data. The data driver receives calibration data outputted in the transform unit.
