Abstract

The invention discloses a display device and a fingerprint identification method thereof. The display device includes a display panel and a backlight module, the backlight module includes a plurality of light-emitting units distributed in a matrix array, the light-emitting units provide light sources required for fingerprint identification, and the method includes: detecting a touch operation on the display panel; During the control operation, determine the touch area of ​​the touch operation on the display panel; determine the light-emitting unit corresponding to the touch area, wherein the touch area corresponds to at least one light-emitting unit, and the light-emitting unit corresponding to the touch area is the first light-emitting unit, The light-emitting units other than the first light-emitting unit in the backlight module are the second light-emitting units; monitor the state mode of the display device, wherein the state mode of the display device includes a display mode; when the display device is in the display mode, increase the number of the first light-emitting unit brightness; and identifying and acquiring the fingerprint image after increasing the brightness of the first light-emitting unit. Through the present invention, the recognition accuracy can be improved.

Description

Technical field[0001]The present invention relates to the field of fingerprint recognition, and more particularly to a display device and a fingerprint recognition method thereof.Background technique[0002]Fingerprints are born with each person. With the development of technology, there have been a variety of display devices with fingerprint recognition functions, such as mobile phones, tablets, and smart wearable devices. Before operating the display device with the fingerprint recognition function, you only need to use your finger touch display device to perform permission verification, simplify the permissions verification process. In addition, as fingerprint recognition application scenarios increases, the direction of fingerprint recognition is also increasingly clear.[0003]In a display device based on optical fingerprint recognition technology, characteristics of the drainage generated by the semiconductor device are generated by the illumination, specifically, the light genera...
