Problems solved by technology

However, the existing light-sensitive fingerprint sensor needs a long measurement time to ensure that the discharge effect generated by the finger touch is large enough to detect the difference between the fingerprint ridge and the fingerprint valley. Therefore, the existing optical-based fingerprint recognition In the display device of advanced technology, its fingerprint detection performance and fingerprint detection rate are poor

Abstract

The invention discloses a display panel, a driving method thereof, and a display device, and relates to the field of display technology. The display panel includes a plurality of gate lines and data lines, and the crossing of the gate lines and the data lines defines a plurality of sub-pixel regions, and the sub-pixel regions There are pixel electrodes and thin film transistors; the display panel also includes a plurality of touch detection units, a plurality of fingerprint identification units and a control circuit, and the driving method includes: the control circuit judges whether to perform fingerprint detection; Scanning the touch detection unit, and scanning the fingerprint identification unit, the first scanning method adopts the first reporting rate; if not, the control circuit scans the touch detection unit in the second scanning mode, and the second scanning method adopts the second reporting rate ; Among them, the first reporting rate is less than the second reporting rate. The invention effectively improves the fingerprint detection performance and fingerprint detection speed of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a driving method thereof, and a display device. Background technique [0002] Fingerprints are inherent to everyone. With the development of technology, a variety of display devices with fingerprint recognition functions have appeared on the market, such as mobile phones, tablet computers, and smart wearable devices. Before operating a display device with a fingerprint recognition function, the user only needs to touch the display device with a finger to perform authorization verification, which simplifies the authorization verification process. Moreover, with the gradual increase in the application scenarios of the fingerprint recognition function, the fingerprint recognition area is gradually changed from Some areas have evolved into full-screen recognition. [0003] In the existing display devices based on optical fingerprint recognition tec...
