Abstract

Disclosed is a method for reducing degradation of a display of an electronic device, the method including: determining whether the display is in a low-power display mode for displaying an always on display (AOD) screen, identifying content of a first screen displayed on the display based on the display displaying the AOD screen, detecting a folding angle of the display, generating a second screen by reorganizing the first screen based on the folding angle, and displaying the second screen on the display.

Claims (41)

1. A method for reducing degradation of a display of an electronic device configured to include a folded state, a flat state, and an intermediate state between the folded state and the flat state, the method comprising:

determining whether the display is in a low-power display mode for displaying an always on display (AOD) screen;

identifying content of a first screen displayed on the display based on the display displaying the AOD screen, the content including a first object including text and/or an image representing a clock, a date, and/or a battery state and a second object including notification received by the electronic device or transferred by the electronic device;

detecting a folding angle of the display;

determining whether a degree of burn-in of the display is less than or equal to a threshold value, based on the folding angle;

generating a second screen, smaller than the first screen, by reorganizing the content of the first screen and reducing a size of the content of the first screen such that all of the content of the first screen is displayed on the second screen and does not overlap a folding axis of the display, based on the degree of burn-in being less than or equal to the threshold value; and

displaying the second screen on the display.

2. The method of claim 1 , wherein the second screen is generated by changing a brightness, color, position, arrangement relationship, and size of the content of the first screen while maintaining the content of the first screen, and

wherein the first screen and the second screen display the AOD screen.

3. The method of claim 1 , wherein the determining of whether the display is in the low-power display mode includes determining, by a processor of the electronic device, whether an event for switching the processor to a sleep state occurs.

4. The method of claim 1 , wherein the identifying of the content of the first screen displayed on the display includes identifying, by a processor of the electronic device, a list of running applications.

5. The method of claim 1 , wherein the detecting of the folding angle of the display includes:

periodically obtaining the folding angle of the electronic device using a sensor module including a motion sensor and/or a magnetic force sensor; and

transferring information related to the content displayed on the display to a processor of the electronic device in response to detecting a change of the folding angle.

6. The method of claim 1 , wherein the generating of the second screen by reorganizing the first screen includes changing display characteristics of the first display.

7. The method of claim 1 , wherein the generating of the second screen by reorganizing the first screen includes analyzing a physical property of the display.

8. The method of claim 1 , wherein the display includes a plurality of areas divided with respect to the folding axis, and

wherein the generating of the second screen by reorganizing the first screen includes moving the AOD screen to one of the plurality of areas.

9. The method of claim 1 , wherein the generating of the second screen by reorganizing the first screen includes moving the AOD screen such that the AOD screen does not overlap a folding axis of the display state,

wherein the first angle having a size greater than the second angle is an angle included in the flat state or the intermediate state.

10. The method of claim 1 , wherein the second screen is generated by changing a brightness, color, position, arrangement relationship of the content of the first screen while maintaining the content of the first screen.

11. The method of claim 1 , wherein the first screen and the second screen display the AOD screen.

12. A foldable electronic device configured to include a folded state, a flat state, and an intermediate state between the folded state and the flat state, the foldable electronic device comprising:

a display configured to display a screen;

at least one sensor configured to obtain a folding angle of the display; and

a processor operatively connected with the display and the at least one sensor,

wherein the processor is configured to:

determine whether the display is in a low-power display mode for displaying an always on display (AOD) screen;

identify content of a first screen displayed on the display based on the display displaying the AOD screen, the content including a first object including text and/or an image representing a clock, a date, and/or a battery state and a second object including notification received by the electronic device or transferred by the electronic device;

detect the folding angle of the display using the at least one sensor;

determine whether a degree of burn-in of the display is less than or equal to a threshold value, based on the folding angle;

generate a second screen, smaller than the first screen, by reorganizing the content of the first screen and reducing a size of the content of the first screen such that all of the content of the first screen is displayed on the second screen and does not overlap a folding axis of the display, based on degree of burn-in being less than or equal to the threshold value; and

control the display to display the second screen on the display.

13. The foldable electronic device of claim 12 , wherein the processor is configured to determine whether an event for switching the processor to a sleep state occurs.

14. The foldable electronic device of claim 12 , wherein the processor is configured to identify a list of running applications.

15. The foldable electronic device of claim 12 , wherein the at least one sensor includes a motion sensor and/or a magnetic force sensor, and

wherein the processor is configured to:

periodically obtain the folding angle of the electronic device using the motion sensor and/or the magnetic force sensor; and

transfer information related to the content displayed on the display to the processor in response to detecting a change of the folding angle.

16. The foldable electronic device of claim 12 , wherein the processor is configured to generate the second screen by changing a brightness, color, position, arrangement relationship of the content of the first screen while maintaining the content of the first screen.

17. The foldable electronic device of claim 12 , wherein the first screen and the second screen display the AOD screen.
