Claim 17:
18. A display system comprising:
a nonvolatile memory configured to store at least one set of panel map data comprising a plurality of offset values corresponding to a plurality of pixels included in a display panel, the panel map data being compressed;
a host processor configured to generate at least one set of compensated frame data by compensating at least one set of frame data based on the panel map data; and
a display driver integrated circuit configured to receive the compensated frame data from the host processor, and control the display panel such that at least one frame image corresponding to the compensated frame data is displayed on the display panel,
wherein the host processor comprises:
a volatile memory configured to store the panel map data;
a panel compensator configured to generate the compensated frame data by compensating the frame data based on the plurality of offset values, and periodically generate updated panel map data based on the frame data or the compensated frame data, the frame data comprising a plurality of pixel values, the compensated frame data comprising a plurality of compensated pixel values, the plurality of compensated pixel values being generated by compensating the plurality of pixel values based on the plurality of offset values, the updated panel map data being different from the panel map data;
a decompressor configured to decompress the panel map data, and provide the decompressed panel map data to the panel compensator;
a compressor configured to compress the updated panel map data, and provide the compressed updated panel map data to the volatile memory; and
a display interface configured to output the compensated frame data,
wherein the volatile memory is configured to periodically store the updated panel map data, and
wherein, after the updated panel map data is generated, the panel compensator is configured to generate the compensated frame data based on the panel map data and the updated panel map data.
