Abstract

The invention discloses a display device and a driving method thereof, which belong to the field of display technology, wherein the display device includes: a display area including a plurality of pixels and a plurality of photosensitive elements; the driving method includes: sensing a touch in the display area control operation to determine the touch area where the touch operation occurs; perform a fingerprint identification operation; wherein, in the fingerprint identification operation, control some pixels in the touch area to be in a bright state and the rest of the pixels to be in a black state, and the control is located in Pixels outside the touch area perform a display function; and, in A fingerprint identification operations, control any pixel in the touch area to be in a bright state during at least one fingerprint identification operation; wherein, A is an integer, and A≥2 ; The photosensitive element receives the light signal and converts it into an electrical signal; processes the electrical signal of the photosensitive element to obtain fingerprint information. Compared with the prior art, the phenomenon that light at a large angle affects the accuracy of fingerprint recognition can be improved, and user experience is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display device and a driving method thereof. Background technique [0002] With the development of display technology, the functions of display devices are becoming more and more abundant. The display device integrates multiple functions such as touch recognition, motion sensing, and fingerprint recognition. Among them, the fingerprint identification 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 in the prior art integrates an optical sensor into a display panel, and uses the optical sensor to realize a fingerprint recognition function. However, the optical path in the display panel is complex, and the optical sensor is more interfered, resulting in lower accuracy of fingerprint recognition and reducin...
