Display circuit board, electronic device including display circuit board, and method of driving electronic device

An electronic device comprising:

• a display panel;
• and
• a display circuit board comprising an auxiliary processor,
• wherein the auxiliary processor:
• reads and decodes a stress table from a memory,
• outputs a second image obtained by compensating for a first image based on the stress table,
• generates new stress data for one slice, based on a grayscale of the second image,
• generates second accumulated stress data by summing first accumulated stress data read from the stress table and the new stress data,
• encodes the second accumulated stress data such that the encoded second accumulated stress data has a data size equal to or less than a target size, and
• stores the encoded second accumulated stress data to the memory.

A method of driving an electronic device, the method comprising:

• reading and decoding a stress table from a memory;
• outputting a second image obtained by compensating for a first image based on the stress table;
• generating new stress data for one slice, based on a grayscale of the second image;
• generating second accumulated stress data by summing first accumulated stress data read from the stress table and the new stress data;
• encoding the second accumulated stress data such that the encoded second accumulated stress data has a data size equal to or less than a target size;
• and
• storing the encoded second accumulated stress data to the memory.
