Abstract: An organic light emitting display device and a driving method thereof are disclosed. The display device has sub-pixels of multiple colors. In one aspect, the organic light emitting display device detects sub-pixels which are positioned at the edges of the panel. Data for the sub-pixels on the edges are reduced so that colors on the edges are less observable.
