<p>The present invention relates to an organic light emitting display device, and specifically, the technical task of the present invention is to provide an organic light emitting display device capable of generating a gray compensation value for a Mura region and a gray compensation value for a normal region separately and compensating image data using the gray compensation values and a driving method thereof. To that end, the organic light emitting display device given in the present invention includes: a panel in which an organic light emitting diode and a plurality of transistors are formed in each of pixels formed by crossing gate lines and data lines; a timing controller which generates a gray compensation value for a Mura region and a gray compensation value for a normal region separately, compensates input image data using the gray compensation values, and outputs the compensated image data; a memory in which compensation data including gray values used for calculating the gray compensation values (β) and brightness difference values by pixel (Δ) is stored; and a driving unit which converts the image data transmitted from the timing controller and outputs the result to the data lines.</p> |
