Patent ID: 8836691

Claim:
A driving method of an organic light emitting display comprising: generating first digital values by sensing deterioration information of organic light emitting diodes respectively included in a plurality of pixels coupled to a data line during two or more first continuous frame periods, the first digital values being generated for same pixels during each one of the first continuous frame periods; storing the first digital values in a memory; generating second digital values by sensing threshold voltage and mobility information of driving transistors respectively included in the plurality of pixels during two or more second continuous frame periods, the second digital values being generated for same pixels during each one of the second continuous frame periods; storing the second digital values in the memory; converting input data into calibration data according to information stored in the memory to display an image having a uniform brightness, irrespective of the deterioration information of the organic light emitting diodes and the threshold voltage and the mobility information of the driving transistors; and supplying a data signal in accordance with the calibration data to the data line, wherein the first continuous frame periods are non-display frame periods.
