    Abstract: An electronic device includes a display driver integrated (DDI) circuit configured to output reference pixel values to be used to obtain target pixel values of a first line, and to output image pixel values associated with a target image; and a panel circuit configured to include the first line that includes pixels configured to display a reference image having the target pixel values, based on the reference pixel values, and a second line that includes pixels configured to display an image corresponding to the target image, based on the image pixel values. The DDI circuit may be further configured to compensate for the image pixel values based on differences between the image pixel values and the reference pixel values.

    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.
