Abstract

The present invention discloses a display device and a fingerprint recognition method thereof. The display device has a display area and a non-display area surrounding the display area. The display area includes a fingerprint identification area which is internally provided with a plurality of fingerprint identification pixels. The display device includes a fingerprint identification array which includes a plurality of fingerprint sensing units arranged in the fingerprint identification area, a control unit which is electrically connected to the fingerprint sensing units and are used for acquiring an overall image of a fingerprint to be identified, determining position coordinates of a fingerprint feature point of the fingerprint to be identified on the display device according to the overall image, then controlling the fingerprint identification pixels to emit light according to the position coordinates to obtain a local image of the fingerprint feature point, and identifying the fingerprint to be identified according to the local image. Through the display device and the fingerprint recognition method, the influences of dry fingers and light crosstalk on fingerprint identification accuracy can be reduced, and the fingerprint identification accuracy is improved.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, to a display device and a fingerprint identification method thereof. 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 the display device with the fingerprint identification function, the user only needs to touch the display device with a finger to perform authority verification, which simplifies the authority verification process. [0003] Existing display panels with fingerprint recognition function all include a plurality of light emitting units and a plurality of fingerprint sensing units, and the fingerprint sensing unit can identify fingerprints according to the reflected light formed by the light emitted by the light sourc...
