Problems solved by technology

In the related technology, the optical fingerprint uses the bright light spot of the display screen to fill the light, and the optical fingerprint due to the optical characteristics of its own lens, the fingerprint image formed by the optical fingerprint will appear darker at the edge and brighter at the center, so that the fingerprint lines are in the center. There will be overexposure, and the image at the edge is blurred, which reduces the sensitivity of fingerprint recognition

Abstract

Embodiments of the present application provide a display screen component and electronic equipment. The display screen assembly includes a display panel, an optical sensor and a controller, the display panel has a fingerprint identification area, the fingerprint identification area includes a central area and an edge area surrounding the central area, and the optical sensor corresponds to the fingerprint The identification area is set, the optical sensor is used to collect the fingerprint image of the target object, and when the fingerprint image is collected, the controller controls the brightness of the central area to be smaller than the brightness of the edge area. The display screen component provided by the present application helps to improve the clarity of the collected fingerprint image, thereby improving the sensitivity of fingerprint identification.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a display screen assembly and electronic equipment. Background technique [0002] With the development of display technology, display devices with fingerprint identification functions have been widely used. The user can use a finger to touch the display screen of the display device, so that the display device can collect and identify the fingerprint lines of the user. In the related technology, the optical fingerprint uses the bright light spot of the display screen to supplement the light, but due to the optical characteristics of its own lens, the fingerprint image formed by the optical fingerprint will appear darker at the edge and brighter at the center, so that the fingerprint lines are in the center. There will be overexposure, and the image at the edge is blurred, which reduces the sensitivity of fingerprint recognition. Contents of the invention [0003]...
