Abstract

The present application discloses a display device and a texture recognition method thereof, which are used for texture recognition in a display area. A display device provided in an embodiment of the present application, the display device includes: a texture recognition module, and a display panel located on the texture recognition module; the display panel includes: a display area located on the display panel A plurality of electroluminescent units, and a light selector located on the side of the electroluminescent unit close to the pattern recognition module; the pattern recognition module includes: a plurality of light emitting components arranged in the corresponding display area and a plurality of photoelectric conversion components; the wavelength band of light emitted by the light-emitting component does not overlap with the wavelength band of light emitted by the electroluminescent unit; the optical selector is configured to: transmit the light emitted by the light-emitting component, And reflect the light emitted by the electroluminescence unit.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device and a texture recognition method thereof. Background technique [0002] At present, mobile display products on the market all have fingerprint identification functions. Currently, commonly used fingerprint identification technologies include optical fingerprint sensors, semiconductor capacitive sensors, radio frequency sensors, and ultrasonic sensors. In the prior art, the optical fingerprint sensor is mainly installed in the non-display area of ​​the display product. The optical fingerprint sensor mainly includes a light source, a prism, and a charge-coupled device (Charge-coupled Device, CCD) or a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS). . However, due to the development of full-screen technology, it is necessary to realize fingerprint recognition under the screen, and the optical fingerprint sensor in...
