Embodiment Construction

[0053] The embodiment of the present application provides a display device, such as figure 1 As shown, the display device includes: a display panel 1, a texture recognition light-emitting substrate 2 located on the light-emitting side of the display panel 1;

[0054] A plurality of photosensitive devices 7 for texture recognition are arranged in the display panel 1;

[0055] The texture recognition light-emitting substrate 2 includes: a substrate, and electroluminescent point light sources arranged on the substrate and corresponding to each of the photosensitive devices one by one.

[0056] The principle of the texture recognition of the display device provided by the embodiment of the present application is as follows: Since the surface of the skin has uneven ridges and valleys, when performing texture recognition, the light emitted by the electroluminescent point light source is irradiated to the positions of the ridges and valleys of the texture and reflected to the surface...

Abstract

The invention discloses a display device and a driving method thereof, which are used for weakening crosstalk between grain valley and ridge signals and improving the effect and reliability of grain recognition. The embodiment of the invention provides a display device. The display device comprises a display panel and a grain recognition light-emitting substrate located on the light-emitting sideof the display panel. A plurality of photosensitive devices for grainrecognition are arranged in the display panel; the grainrecognition light-emitting substrate comprises a substrate body and electroluminescent point light sources which are arranged on the substrate body and correspond to the photosensitive devices in a one-to-one mode.

Description

technical field [0001] The present application relates to the technical field of texture recognition, in particular to a display device and a driving method thereof. Background technique [0002] With the rapid development of display technology, at present, display products with fingerprint recognition function have gradually become popular. [0003] In the prior art, the fingerprint identification collects the reflected light of the fingerprint obtained after irradiation by the optical fingerprint collection device, transmits it to the light receiving unit, receives the reflected light of the finger fingerprint transmitted by the optical fingerprint collection device, and generates a fingerprint according to the reflected light The image data is transmitted to the information processing unit for receiving the fingerprint image data and generating fingerprint identification information according to the fingerprint image data. However, fingerprint identification is easily in...
