Embodiment Construction

[0030] 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.

[0031] There are generally two solutions for integrating optical fingerprint recognition in a display device. One is the solution of using an external light source. The external light source mostly uses near-infrared LEDs. The external light source is combined with an optical fingerprint sensor to realize fingerprint recognition. The accuracy and sensitivity of fingerprint recognition in this solution are high. However, it is difficult to realize and display the external light source. The integration of the screen...

Abstract

The embodiment of the invention discloses a display device. The display device comprises a substrate, a light-emitting component array, an optical conversion layer and an optical fingerprint sensing layer, wherein the light-emitting component array is arranged on the substrate, the optical conversion layer is arranged at one side, far away from the substrate, of the light-emitting component arrayand can be used for converting a part of light emitted from the light-emitting component to near-infrared light, and the optical fingerprint sensing layer is arranged at one side, far away from the optical component, of the substrate. With the display device provided by the technical scheme of the embodiment of the invention, the fingerprint identification performance of the display device is improved, and the optical fingerprint identification accuracy and sensitivity is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display device. Background technique [0002] In recent years, display devices have played an increasingly important role in people's lives, and their functions and types have become increasingly diversified. For example, display devices are mostly set to integrate display, touch, pressure touch and fingerprint recognition functions For another example, the display function of the display device can be divided into liquid crystal display (LCD), organic electroluminescent display (OLED), electrophoretic display, and quantum dot light-emitting display. [0003] However, the existing display devices with fingerprint recognition function have poor accuracy and sensitivity of fingerprint recognition. Contents of the invention [0004] The present invention provides a display device to improve the accuracy and sensitivity of optical fingerprint recogn...
