Display control method and electronic device supporting same

A display control method of an electronic device comprising a display that comprises a first region having a first pixel density and a second region having a second pixel density less than the first pixel density, the method comprising:

• identifying a first brightness level for the first region;
• identifying that the first brightness level exceeds a specified threshold;
• determining a second brightness level for the second region, based on at least one of the first brightness level, the first pixel density, and the second pixel density;
• identifying a third region of the display defined to include the second region along an edge of the first region;
• and
• configuring the brightness of the second region and the third region as the second brightness level,
• wherein the electronic device comprises an optical sensor disposed under the second region.

An electronic device comprising:

• a display;
• an optical sensor disposed under the display;
• and
• a display driver integrated circuit electrically connected to the display,
• wherein the display comprises:
• a first region having a first pixel density, and
• a second region having a second pixel density, which is less than the first pixel density, and corresponding to a disposition region of the optical sensor, and
• wherein the display driver integrated circuit is configured to:
• identify a first brightness level for the first region,
• in case that the first brightness level exceeds a specified threshold, determine a second brightness level for the second region, based on at least one of the first brightness level, the first pixel density, and the second pixel density,
• identify a third region of the display defined to include the second region along an edge of the first region, and
• configure the brightness of the second region and the third region as the second brightness level.
