Abstract
An organic light emitting display that can stably extract information from pixels. A driving method of the organic light emitting display includes: 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 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 pixels during two or more continuous frame periods; storing the second digital values in the memory; converting input data into calibration data according to the 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 mobility information of the driving transistors; and supplying a data signal in accordance with the calibration data to the data line.
