ORGANIC LIGHT EMITTING DISPLAY AND DRIVING METHOD THEREOF

摘要

An organic light emitting display and a driving method thereof are proved to realize the uniform brightness of an image in regardless of deterioration by supplying calibration data through which the deterioration of the organic light-emitting diode is compensated with a detected temperature. In an organic light emitting display and a driving method thereof, a temperature sensor measure the temperature of a pixel(132). A first analog to digital converter converts the temperature measured in the temperature sensor into a digital value, and a digital controller receives digital data from a first ADC and generates a control signal corresponding to the digital data. A sensing unit extracts the deterioration degree of the organic light-emitting diode in the pixel, and a second analog digital converter converts a voltage of the organic light-emitting diode from a sensing circuit into digital data.
