Abstract

The present invention provides a method for adjusting the backlight of the screen and a mobile terminal, wherein the method for adjusting the backlight of the screen includes: when the fingerprint collection function is enabled on the mobile terminal, other areas of the display screen except for the fingerprint identification area A mask with a preset color is displayed on the area; when the mobile terminal closes the fingerprint collection function, the mask is controlled to hide. The present invention weakens the light transmitted from other areas except the fingerprint identification area through the mask, thereby reducing the brightness of the backlight in other areas except the fingerprint identification area, reducing the area of ​​the highlighted area on the display screen, and realizing the localization of the screen. The backlight adjustment not only ensures the recognition rate of optical fingerprints, but also alleviates the glare caused by the high brightness of the entire display screen. In addition, when it is detected that the fingerprint collection function is turned off, the mask is controlled to hide, so as to prevent the mask from affecting the normal display of the display screen.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method for adjusting a screen backlight and a mobile terminal. Background technique [0002] With the development of fingerprint identification technology, screen fingerprint has attracted more and more attention due to its high screen ratio, aesthetics and convenience. Optical fingerprint, as a main way to realize screen fingerprint, has set off a wave of upsurge in the fingerprint recognition industry, leading the development of screen fingerprint recognition technology. [0003] Optical fingerprints use the light from the screen backlight to collect fingerprint images. Therefore, high-intensity backlights must be set in the fingerprint recognition area to capture clearly visible fingerprint images. However, the brightness of the entire screen is too high at this time, which will cause glare. Contents of the invention [0004] Embodiments of the present invention pr...
