Electronic device comprising multiple displays and method for reducing deviation in screen quality of multiple displays

An electronic device, comprising:

• a first display;
• at least one second display different from the first display;
• a first display driver integrated circuit (DDI) configured to drive the first display;
• at least one second DDI configured to drive the at least one second display;
• and
• at least one processor, comprising processing circuitry,
• wherein at least one processor, individually and/or collectively, is configured to:
• generate a first image to be displayed through the first display and a second image to be displayed through the at least one second display;
• accumulate the first image to generate a first prediction map indicative of a degree of burn-in of the first display;
• accumulate the second image to generate a second prediction map indicative of a degree of burn-in of the at least one second display;
• identify a similarity of first burn-in data corresponding to the first prediction map and second burn-in data corresponding to the second prediction map;
• based on the similarity being greater than or equal to a designated threshold, stop accumulating an image among the first image and the second image and maintain accumulating another image among the first image and the second image,
• generate a first compensation map for compensating for burn-in of the first display based on the first prediction map, and store the generated first compensation map in a first memory;
• generate a second compensation map for compensating for burn-in of the at least one second display based on the second prediction map, and store the generated second compensation map in a second memory;
• convert the first image into a first compensation image based on the first compensation map, and control the first DDI to allow the first display to display the first compensation image;
• and
• convert the second image into a second compensation image based on the second compensation map, and control the second DDI to allow the at least one second display to display the second compensation image.
