Abstract
Discussed is an organic light emitting display device and a driving method thereof, which reduce a size of corrected image data by using a color compression scheme to decrease a capacity of a memory, and reduce a size of an integrated circuit (IC) to increase a manufacturing yield. The method can include loading a compensation coefficient stored in a memory, correcting image data by applying the compensation coefficient to a data voltage supplied to a pixel, compressing, in different compression schemes, corrected image data of a color having high visual perceivability and corrected image data of a color having low visual perceivability, and synthesizing corrected image data of red, green, and blue pixels, which are compressed by the different compression schemes, to store the synthesized image data in a memory.
