Problems solved by technology

But for some types of display screens, when the brightness control level is small, for example, when the control level of the display screen is only 1024, the display screen will still be in the dark part during the change from bright to dark. There is a step-like flickering problem in the interval, which affects the user experience

Embodiment Construction

[0095] The technical solution in this application will be described below with reference to the accompanying drawings.

[0096] In order to better understand the method for adjusting display brightness according to the embodiment of the present application, some basic features of display brightness adjustment are briefly described below.

[0097] Generally, a display screen has multiple dimming steps (brightness control steps), and when the display screen is in different dimming steps, the display screen has different brightness. When the display brightness value of the display screen needs to be adjusted, the dimming order of the display screen can be adjusted by controlling the driving current or driving voltage of the display screen, thereby realizing the adjustment of the brightness of the display screen.

[0098] A display screen of an electronic device may also be referred to as a screen of the electronic device, and the brightness of the display screen specifically refe...

Abstract

The present application provides a method and an electronic device for adjusting display brightness. The method for adjusting display brightness includes: acquiring an initial brightness value of a display screen; obtaining an ambient light signal, and determining a target brightness value of the display screen according to the ambient light signal; according to the initial brightness value, the target brightness value and The current pixel value of the image to be displayed is obtained to obtain the target pixel value of the image to be displayed; and the image to be displayed is presented on the display screen according to the target pixel value of the image to be displayed. The application can adjust display brightness more smoothly.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, to a method for adjusting display brightness and an electronic device. Background technique [0002] The brightness of the display screen of an electronic device is one of the important factors affecting user experience. In order to improve the user experience, the display screen of the electronic device needs to present different display brightnesses to the user under different intensities of ambient light. When the ambient light is strong, the display screen needs to display higher brightness, and when the ambient light is weak, the display screen needs to display lower brightness. [0003] When the ambient light changes from dark to bright, in order to be able to clearly see the content displayed on the display, the user hopes that the display will brighten quickly. When the ambient light changes from bright to dark, in order to ensure the comfort of the eyes...
