Abstract

The invention discloses a display device and a driving method thereof, and belongs to the technical field of display. The display device comprises a display area, wherein the display area comprises aplurality of pixels and a plurality of light sensing elements; The driving method includes: sensing a touch operation in the display area to determine a touch area in which the touch operation occurs;performing a fingerprint identification operation A times; In the fingerprint identification operation, some pixels in the touch control area are controlled to be in a bright state and other pixels are in a black state, and pixels located outside the touch control area are controlled to perform a display function. Also, in the A fingerprint identification operation, any pixel in the control toucharea is in a bright state in at least one fingerprint identification operation; Where A is an integer and A >= 2; The light sensing element receives the optical signal and converts it into an electrical signal. The electrical signal of the photosensitive element is processed to obtain fingerprint information. Compared with the prior art, the phenomenon that large-angle light affects the accuracyof fingerprint identification can be improved, and the user experience is improved.

Description

Technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device and a driving method thereof. Background technique [0002] With the development of display technology, the functions of the display device become more and more abundant. The display device integrates multiple functions such as touch recognition, motion sensing, and fingerprint recognition. Among them, the fingerprint recognition function can identify the user's fingerprint information, and then realize the corresponding function. Fingerprint recognition has high security and is favored by users. [0003] A display device provided by the prior art integrates an optical sensor in a display panel, and uses the optical sensor to realize a fingerprint recognition function. However, the optical path in the display panel is complicated, and the optical sensor is subject to more interference, resulting in low accuracy of fingerprint recognition and reducin...
