Problems solved by technology

The realization of the under-screen fingerprint recognition technology requires the display screen to have a local highlight function. The realization of this function mainly depends on the cooperation between the backlight brightness of the screen and the parameter configuration of the alpha mask, but this process has very strict requirements on the synchronization timing. , the configuration parameters of the backlight brightness take effect first, which will cause the display to flicker, and the configuration parameters of the alpha mask take effect first, which will cause the display to flicker black

Abstract

The embodiments of the present invention provides a screen backlight setting method, an electronic device, and a computer readable storage medium and belongs to the technical field of communication. The method includes the following steps that: the parameters of the backlight brightness of a screen are configured; after a first preset number of frame synchronization signals arrive, the parametersof the mask of the screen are configured; after a second preset number of frame synchronization signals arrive, the configured parameters of the backlight brightness and the configured parameters of the mask synchronously take effect. The frame synchronization signals are awaited, so that backlight brightness configuration and mask configuration are highly synchronized, and thus, the sudden brightness or sudden darkness of the screen can be avoided.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a screen backlight setting method, an electronic device, and a computer-readable storage medium. Background technique [0002] With the development of electronic terminal technology, the penetration rate of smart electronic terminals such as mobile phones, tablet computers, and laptop computers is getting higher and higher. Because most of these electronic devices store all kinds of information of users, people pay more and more attention to security issues, and fingerprint unlocking technology has thus obtained great development. Under-screen fingerprint recognition technology, also known as invisible fingerprint technology, is one of the more popular fingerprint unlocking technologies at present. It mainly completes the fingerprint recognition and unlocking process through the bottom of the screen glass. The realization of the under-screen fingerprint reco...
