Problems solved by technology

[0003] Display devices can improve their security through 3D biometrics, such as face recognition (Face ID) or fingerprint recognition. The 3D biometrics used in existing display devices need to occupy the non-display area of ​​the display panel in the display device, resulting in the display device being unable to Realize the effect of full screen

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0025] As mentioned in the background technology, the existing display devices cannot realize the effect of 3D biometric recognition on the basis of a full screen. After careful research, the inventor found that the reason for this technical problem is that 3D biometric recognition requires a light-emitting module to emit Structured light irradiates structured light onto the surface of the object to be tested. However, the display panel contains multiple pixels, which will block the structured light and make the re...

Abstract

The invention discloses a display device and a method for realizing feature recognition by using the display device. The display device includes: a display panel; a light-emitting module which is located on the side, away from the light-emitting face of the display panel, of the display panel, wherein the light-emitting module is used for emitting parallel light, and the parallel light penetratesthrough the display panel and then generates a plurality of diffraction light spots; and an imaging acquisition module, wherein the view finding range of the image acquisition module covers the projection range of at least part of the parallel light after the parallel light penetrates through the display panel. According to the embodiment of the invention, the display device not only can realize afull screen, but also can realize 3D biological recognition.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display device and a method for implementing feature recognition using the display device. Background technique [0002] With the development of the display technology, the display device plays an increasingly important role, and correspondingly, the security requirements of the display device are also higher and higher. [0003] Display devices can improve their security through 3D biometrics, such as face recognition (Face ID) or fingerprint recognition. The 3D biometrics used in existing display devices need to occupy the non-display area of ​​the display panel in the display device, resulting in the display device being unable to Realize the effect of full screen. Contents of the invention [0004] The present invention provides a display device and a method for realizing feature recognition by using the display device, so that the display dev...
