1. An electronic device comprising:
a display panel;
a nonvolatile memory; and
a display driver circuit connected with the display panel and the nonvolatile memory and configured to be connected with an external device through a video interface channel, and connected with the display panel and the nonvolatile memory, the display driver circuit comprising a frame buffer and a display memory,
wherein the display driver circuit is further configured to, in a first mode:
distribute and store data, received through the video interface channel, in the frame buffer and the display memory, and
program the data distributed and stored in the frame buffer and the display memory in the nonvolatile memory, and
wherein the display driver circuit is further configured to, in a second mode:
load the data stored in the nonvolatile memory to the display memory,
store frame data, received through the video interface channel in the frame buffer,
generate compensated frame data by compensating for the frame data by using the data, and
send the compensated frame data to the display panel,
wherein the display driver circuit is configured to be connected with another external device through a sideband channel.
