Problems solved by technology

In order to increase the bendability of the display panel, it is more commonly used to directly integrate the touch electrodes on the display panel, but this technology will cause the light to be blocked by the touch electrodes during fingerprint recognition, causing the light to pass through. The decline of the rate, which causes the reduction of the light transmission of fingerprint recognition, affects the accuracy of fingerprint recognition

Abstract

The invention discloses a display panel and a display device. The display panel includes a display area, the display area includes touch electrodes and a plurality of fingerprint recognition units; the display panel includes a base substrate and a plurality of pixel units located on the base substrate, each Each pixel unit includes at least three sub-pixels, and the sub-pixels include sub-pixel opening areas; the touch electrode is a metal grid structure, and the orthographic projection of the metal grid to the base substrate is located between adjacent sub-pixel opening areas; the base substrate It includes a plurality of transmission areas and non-transmission areas, no metal grid is set in the transmission area, and the non-transmission area is the area on the substrate except the transmission area; a pixel unit includes at least one transmission area . The display device includes the above-mentioned display panel. The present invention can increase the amount of light reflected to the fingerprint identification unit through the fingerprint valleys and ridges on the surface of the finger without affecting the touch sensitivity of the touch electrode, thereby improving the identification accuracy of the fingerprint identification unit.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] Fingerprints are inherent to each person and are unique. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, before operating the display device with fingerprint recognition function, the user only needs to touch the fingerprint recognition module of the display device with his finger to perform authority verification, which simplifies the authority verification process. [0003] Optical fingerprint recognition technology is widely used in fingerprint recognition modules of various display devices due to its advantages of good stability and high recognition sensitivity, and is currently a relatively mature solution. The principle of optical...
