Method and device for adjusting brightness of display screen

Abstract

The invention discloses a method and a device for adjusting the brightness of a display screen. The brightness of the display screen of a display terminal can be adjusted through an application of the display terminal. The method comprises presetting a view control for the application; reading the preset view control and displaying the view control on the display screen in a view adding mode when the application view is started; removing the displayed view control in a view removal mode when the application is closed. The preset view control specifically comprises attributes of the preset view control. The attributes of the view control comprise a view layer of the displayed view, the color transparency of the displayed view, the type of a response to a user input instruction and the view size. According to the method and the device for adjusting the brightness of the display screen, the view control is displayed so as to adjust the brightness of the display screen, only one view control rather than a set of resources is added, and accordingly the development effort and the system cost can be small, the modification of a system bottom layer is not involved, and the applicability is strong.

Description

technical field [0001] The invention relates to the field of computers and electronic equipment, in particular to a method and a device for adjusting the brightness of a display screen. Background technique [0002] In an existing computer terminal or mobile phone terminal, when a specific application program is running, the display screen will use different display brightness, for example, the display screen will use one of two display modes: normal mode or night mode. Night mode is a display mode with less brightness, which makes the screen more comfortable for the eyes to see in a dark environment. After selecting the night mode in the corresponding application, it will give the user a way to protect the eyes and make the eyes look at the screen more comfortably than when using the normal mode. When the application is moved to the background, the display screen can be restored to the previous display mode. Of course, this method is different from the overall adjustment ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are two commonly used solutions for the realization of night mode: (1) Adding resources, such as developing two image resources, one resource is used to realize the normal mode, and the night mode is realized by replacing resources. The defect of this solution is that it needs Adding a certain amount of development workload will also have a certain impact on the size of the application itself due to the increase of certain image resources, and the system overhead of switching operations is relatively large

(2) Adjust the brightness of the system to achieve night mode. At present, there are many designers and manufacturers of computers and mobile phones, and there are also various bottom-level modifications to operating systems such as android. incomplete matching problem
