Abstract: An organic light emitting display and a method for driving the organic light emitting display. The organic light emitting display includes a display unit, a data accumulator, and a data compensator. The display unit is configured to be driven by image data. The data accumulator is configured to compress and accumulate first data corresponding to a first portion of the image data for driving a first region of the display unit, identify a second region of the display unit from the first region by analyzing the accumulated first data, and compress and accumulate second data corresponding to a second portion of the image data for driving the second region with a compression ratio based on a size of the second region. The data compensator is configured to compensate the image data based on the accumulated first and second data.

Abstract: A method of controlling a dimming operation is disclosed. In one aspect, the method includes determining the brightness of an input image frame based on input image data, determining an input dimming value based on the brightness of the input image frame, selectively performing the dimming operation is based on a comparison of an absolute value of a difference between the input dimming value and a current output dimming value against a predetermined threshold value, where a value generated by adjusting the current output dimming value by a predetermined adjustment value is output as a next output dimming value when performing the dimming operation, and the input dimming value is output as the next output dimming value when not performing the dimming operation.
