Abstract

The invention discloses a display device and a method for realizing feature identification by using the display device. The display device includes: a display panel; a light-emitting module, the light-emitting module is located on the side of the display panel away from the light-emitting surface thereof, the light-emitting module is used for emitting parallel light, and the parallel light passes through the display panel. generating a plurality of diffracted light spots; and an image acquisition module, the viewing range of the image acquisition module covers at least part of the projection range of the parallel light after passing through the display panel. The embodiments of the present invention can enable the display device to realize both a full screen and 3D biometric identification.

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 realizing feature recognition by using the display device. Background technique

[0002] With the development of display technology, the role played by the display device becomes larger and larger, and accordingly, the security requirements for the display device are also higher and higher.

[0003] The display device can improve its security through 3D biometric identification, such as face recognition (Face ID) or fingerprint identification. The 3D biometric identification used in the existing display device needs to occupy the non-display area of ​​the display panel in the display device, resulting in the display device unable to Realize the effect of full screen. SUMMARY OF THE INVENTION

[0004] The present invention provides a display device and a method for realizing feature recognition by using the display d...

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 herein 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, the drawings only show some but not all structures related to the present invention.

[0025] As mentioned in the background art, the existing display device cannot realize the effect of 3D biometric identification on the basis of the full screen. After careful research, the inventor found that the reason for this technical problem is: 3D biometric identification requires a light-emitting module to emit light. Structured light irradiates the surface of the object to be measured with structured light. However, the display panel contains multiple pixels, and the pixels will block the structured light, making the identi...
