An electronic device is provided. The electronic device includes a display, an optical sensor disposed below the display, and at least one processor, wherein the display includes a first region having a first pixel density and a second region having a second pixel density less than the first pixel density and corresponding to the disposed region of the optical sensor, the at least one processor determines a second brightness level for the second region on the basis of at least one among a first brightness level of the first region, the first pixel density, and the second pixel density when the first brightness level exceeds a predetermined threshold, identifies a third region, defined to include the second region, of the display along an edge of the first region, and sets the brightness of the second and third regions to the second brightness level.

First claim

What is claimed is:

1. An electronic device comprising:
a display;
an optical sensor disposed under the display;
memory storing one or more computer programs; and
one or more processors communicatively coupled to the display, the optical sensor, and the memory,
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 one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device 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, the second region being disposed along an edge of the first region, the third region being defined along all edges of the first region to surround the first region, and
configure the brightness of the second region and the third region as the second brightness level.

2. The electronic device of claim 1 , wherein the one or more computer programs further include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to:
obtain a dominant color from a screen displayed on the first region, excluding the third region, and
apply a gradation effect to the third region, based on the obtained color.

3. The electronic device of claim 1 , wherein the one or more computer programs further include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to configure a maximum brightness level at which the second region is maximally bright as the specified threshold.

4. The electronic device of claim 3 , wherein the one or more computer programs further include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to:
determine the maximum brightness level as the second brightness level in case that the first brightness level exceeds the specified threshold by a specified level range or more, and
determine a brightness level lower than the maximum brightness level as the second brightness level in case that the first brightness level exceeds the specified threshold by less than the specified level range.

5. The electronic device of claim 3 , wherein one or more computer programs further include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to:
identify an on-pixel ratio (OPR) of the display,
in case that the OPR of the display exceeds a specified OPR threshold, determine the maximum brightness level as the second brightness level, and
in case that the OPR of the display does not exceed the specified OPR threshold, determine a brightness level lower than the maximum brightness level as the second brightness level.

6. The electronic device of claim 1 , wherein one or more computer programs further include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to:
identify the third region having a first width in case that the first brightness level exceeds the specified threshold by less than a specified level range, and
identify the third region having a second width greater than the first width in case that the first brightness level exceeds the specified threshold by the specified level range or more.

7. The electronic device of claim 1 , wherein one or more computer programs further include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to:
supply a first driving power to the second region, and
supply a second driving power less than the first driving power to the third region, as at least part of configuring the second region and the third region as the second brightness level.

8. The electronic device of claim 1 , wherein the one or more computer programs further include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to:
in case that the first brightness level does not exceed the specified threshold, determine a third 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, and
configure the brightness of the second region as the third brightness level corresponding to the first brightness level.

9. The electronic device of claim 1 , wherein the one or more computer programs further include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to identify the first brightness level for the first region while displaying a screen using the display.

10. The electronic device of claim 1 , wherein the first region includes a plurality of first pixel regions based on the first pixel density, and the second region includes a plurality of second pixel regions and a plurality of non-pixel regions based on the second pixel density.

11. The electronic device of claim 1 , wherein the brightness of the second region and the third region is configured as the second brightness level based on a degree of folding of the electronic device.

12. 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;
