Display screen and electronic equipment

Abstract

The invention provides a display screen and electronic equipment, and the display screen comprises a first display region and a second display region, the first display region comprises a plurality offirst pixels, and the second display region comprises a plurality of second pixels. The invention also comprises a display driving circuit for driving the plurality of first pixels to display; a fingerprint identification driving circuit used for driving the plurality of second pixels to emit light during fingerprint unlocking; a fingerprint unlocking detection module which is used for detectingwhether a user triggers fingerprint unlocking or not; and a controller which is used for controlling the fingerprint unlocking module to unlock when the fingerprint unlocking detection module detectsthat the user triggers fingerprint unlocking; and controlling the fingerprint identification driving circuit to control the plurality of second pixels to emit light at the same time, or controlling the display driving circuit to control the plurality of first pixels to display, and controlling the fingerprint identification driving circuit to control the plurality of second pixels to emit light atthe same time. Therefore, cross grains are prevented from appearing in the acquired optical fingerprint, the generation quality of the fingerprint image is improved, and the fingerprint unlocking accuracy and success rate are further improved.

Description

technical field [0001] The present application relates to the technical field of panel display, in particular to a display screen and electronic equipment. Background technique [0002] With the development of electronic technology, the display screen of electronic equipment is gradually developing into a full screen, and the screen-to-body ratio is getting higher and higher, which makes the current mainstream capacitive fingerprint module nowhere to be placed, and the optical fingerprint under the screen emerges as the times require. [0003] However, the inventors found that when the fingerprint recognition technology is used for fingerprint recognition under the screen, the imaging is not clear and the quality of the generated fingerprint image is poor, which leads to a low accuracy rate and success rate of fingerprint recognition. Contents of the invention [0004] The embodiment of the present application proposes a display screen, which is used to solve the phenomeno...
