1. A display system comprising:
a host processor configured to compensate at least one set of frame data based on at least one set of panel map data comprising a plurality of offset values corresponding to a plurality of pixels of a display panel, generate at least one set of compensated frame data, and output the compensated frame data;
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,
a first memory configured to store the panel map data and provide the panel map data to the host processor,
a display characteristic detector configured to periodically generate updated panel map data by analyzing a characteristic of the display panel;
wherein the host processor comprises:
a second memory configured to receive from the first memory and 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, 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; and
a display interface configured to output the compensated frame data;
wherein the updated panel map data is different from the panel map data;
wherein the second memory is configured to periodically store the updated panel map data
wherein the host processor further compensates the at least one set of frame data based on the updated panel map data.
