Abstract
A display driver integrated circuit includes a first memory, a compensator, an accumulator and a second memory. The first memory stores a plurality of compensation data that are used to compensate for deterioration of a plurality of pixels. The compensator generates a plurality of output image data for image display by compensating a plurality of input image data based on the plurality of compensation data. The accumulator groups the plurality of pixels into a plurality of blocks, generates a plurality of block image data by sampling the plurality of output image data in block units, generates a plurality of block accumulation data in block units based on the plurality of block image data, and generates a plurality of pixel accumulation data in pixel units by synthesizing portions of the plurality of output image data and portions of the plurality of block accumulation data. The second memory stores the plurality of block accumulation data in a first period. The plurality of pixel accumulation data may be stored in a third memory in a second period longer than the first period.
