Problems solved by technology

[0003] For the display panel of this kind of full-screen fingerprint identification, in order to give the fingerprint identification unit enough detection time to improve the accuracy of fingerprint identification, the scanning time of the fingerprint identification unit should not be too short, which will lead to fingerprint identification. The cycle is too long, which affects the detection performance

Abstract

The invention provides a display panel, a fingerprint identification driving method thereof and a display device. The display panel comprises a touch module used for detecting a touch position, a plurality of fingerprint identification areas, a scanning driving module used for generating a scanning signal, a processing module used for determining a target fingerprint identification area and dividing the target fingerprint identification area into a target area and a non-target area, and a control module used for controlling the scanning driving module to execute different scanning schemes on the target area and the non-target area; the target area is scanned according to a first scanning scheme, the non-target area is scanned according to a second scanning scheme, and the scanning time ofthe first scanning scheme is longer than that of the second scanning scheme. According to the display panel, the fingerprint identification driving method thereof and the display device provided by the embodiment of the invention, the scanning time of the area with the effective fingerprint information can be longer, the fingerprint scanning effect is improved, and the user experience is improved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel, a fingerprint recognition driving method thereof, and a display device. Background technique [0002] More and more electronic devices are equipped with fingerprint sensors. Through the collection and identification of user fingerprints, the purpose of distinguishing user identities can be achieved, so as to realize the function switch control of mobile devices more conveniently. For the display panel with fingerprint recognition function, in order to better realize the full-screen design and avoid the fingerprint recognition area from occupying the space of the non-display area, the fingerprint recognition technology under the screen can be used to set the entire display area as the fingerprint recognition area, that is, A plurality of fingerprint identification units are correspondingly arranged in the entire display area. [0003] For the display...
