Abstract

The present document provides a method and apparatus for managing a display screen, and the display screen includes at least two display areas. The method includes: detecting a first display effect damaged value of a first display area in the at least two display areas; comparing the first display effect damaged value with a predetermined threshold value, and outputting a first comparison result; and when the first display effect damaged value is larger than the threshold value, adjusting a display effect of the first display area to a first display effect based on the first display effect damaged value, to match the first display effect with a second display effect of a second display area without stains. Through the above technical scheme, adjustment is performed on display effect of the display screen, which guarantees the display effect of the display screen and makes the user experience of users enhance greatly.

or

in the process of a device in which the display screen is located being in an operating state, detecting the first display effect damaged value of the first display area in the at least two display areas at regular time periods.

5. The method according to claim 2, wherein, the display effect is contrast, and the step of adjusting a display effect of the first display area to a first display effect based on the first display effect damaged value to match the first display effect with a second display effect of a second display area without stains comprises:

adjusting a contrast of the first display area to a first contrast using a comparison relationship table between display effect damaged values and contrasts, to match the first contrast with a second contrast of the second display area without stains.

6. The method according to claim 2, wherein, the display effect is brightness, and the step of adjusting a display effect of the first display area to a first display effect based on the first display effect damaged value to match the first display effect with a second display effect of a second display area without stains comprises:

adjusting a brightness of the first display area to a first brightness using a comparison relationship table between display effect damaged values and brightnesses, to match the first brightness with a second brightness of the second display area without stains.

14. The method according to claim 2, wherein, the threshold value is determined through following steps:

collecting at least one parameter value used for determining the threshold value; and

determining the threshold value based on the at least one parameter value.

15. The method according to claim 14, wherein, the step of detecting a first display effect damaged value of a first display area in the at least two display areas comprises:

when a device in which the display screen is located is powered on, detecting the first display effect damaged value of the first display area in the at least two display areas;

or

when a device in which the display screen is located converts from an operating state with low power consumption to an operating state with high power consumption, detecting the first display effect damaged value of the first display area in the at least two display areas;
