Array substrate, display device, and pattern recognition method therefor

Abstract

The embodiment of the invention provides an array substrate, a display device, and a pattern recognition method therefor, and relates to the technical field of fingerprint recognition. The pattern recognition can be achieved in a display region of the display device, and the implementation of a narrow frame is facilitated. The array substrate comprises a plurality of light-emitting devices which are disposed on the substrate, and are located in a display region. The array substrate also comprises a shading layer which is disposed on the substrate. The shading layer is used for the shading of the light with at least one primary color, and the shading layer is provided with a plurality of imaging holes located in the display region, wherein the imaging holes are not overlapped with the orthographic projection of the light-emitting devices on the substrate. The array substrate also comprises a pattern recognition layer disposed below the shading layer, and the pattern recognition layer comprises sensor units corresponding to the imaging holes. The light emitted by at least one light-emitting device located around one imaging hole can be reflected to pass through the imaging holes to arrive at the sensor unit through a to-be-recognized body at a display side of the display device. The array substrates is used for achieving the pattern recognition in the display region.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to an array substrate, a display device and a pattern identification method thereof. Background technique [0002] With the continuous improvement of living standards, various terminal devices have become necessities in life, and users have higher and higher requirements for terminal devices. In terms of security, because of the uniqueness of the individual texture, the texture recognition has an excellent privacy protection function, so the texture recognition is widely used in various terminal devices to increase user experience and security. [0003] Since the texture recognition device in the existing display device is generally arranged at the frame position of the display device, this is not conducive to realizing a narrow frame and affects the appearance of the display device.
