Display device including display panel, method to operate the same, and display system including the same

A method to operate a display device including pixels, the method comprising:

• obtaining source data units from accumulated stress data corresponding to the pixels;
• determining a representative value corresponding to the source data units;
• changing a portion of data bits of each of the source data units according to the representative value, to generate changed source data units;
• and
• encoding the changed source data units to generate compressed data.

An electronic device comprising:

• a processor;
• and
• a display device configured to display an image in pixels according to image data from the processor,
• wherein the display device comprises:
• a display panel comprising the pixels;
• a controller configured to control the display panel;
• and
• a working memory connected to the controller,
• wherein the controller is configured to:
• update accumulated stress data corresponding to the pixels based on first image frames;
• determine a representative value of source data units obtained from the accumulated stress data;
• change a portion of data bits of each of the source data units according to the representative value, to generate changed source data units;
• and
• encode the changed source data units to generate compressed data, and store the compressed data in the working memory.
