A controller for a display device includes an adjuster and a compensator. The adjuster adjusts at least one parameter of a modeling equation based on a measured current of a pixel. The modeling equation including the at least one adjusted parameter is indicative of a real time degree of degradation of the pixel. The compensator compensates for image data corresponding to emission of light from the pixel.

Organic light emitting display and method for driving the same

An organic light emitting display device includes a plurality of pixels in a display area; a data driver configured to supply a data signal to the pixels; and a data converter configured to output a correction image data utilized in generation of the data signal, and the data converter is configured to generate a stress data corresponding to an input image data, to accumulate and store at least a portion of the stress data in a compressed state, and to generate the correction image data obtained by correcting the input image data according to the accumulated stress data.

Organic light emitting display device for compensation of pixel degradation and driving method thereof

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.
