Abstract:
1. An organic light emitting display device, comprising: a pixel unit formed at the intersection of a plurality of scan lines and a plurality of data lines, the pixel unit including a plurality of pixels divided into a plurality of pixel blocks, wherein each pixel block includes a plurality of adjacent pixels; a scan driver configured to supply a plurality of scan signals to the scan lines; a data driver configured to supply a plurality of data signals to the data lines; and a data compensation unit storing a plurality of correction coefficients respectively corresponding to the pixel blocks, wherein the data compensation unit is configured to i) change input data for each pixel block based on the corresponding correction coefficient and ii) supply the changed input data to the data driver, wherein the number of pixels arranged in a first direction in each of the pixel blocks is different from the number of pixels arranged in a second direction which is perpendicular to the first direction.
