Display panel and display device

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises an array substrate which comprises a first substrate; a color film substrate which comprises a second substrate, a first light-transmitting hole formed in one side, facing the array substrate, of the second substrate, and a shading part surrounding the first light-transmitting hole, the shading part comprises at least one group of sub shading parts, each sub shading part comprises a first shading layer and a first connecting layer in the direction perpendicular to the plane where the second substrate is located, the first connecting layers are located on the sides, away from the second substrate, of the first shading layers, and the surface, facing the first connecting layer, of the first shading layer and the surface, facing the first shading layer, of the first connecting layer are mutually wedged; and a fingerprint recognition unit which is locatedon one side, facing the color film substrate, of the first substrate, wherein the fingerprint identification unit comprises a plurality of photosensitive devices arranged in an array, and the orthographic projection of the photosensitive devices to the plane where the second substrate is located at least partially overlaps with the orthographic projection of the first light holes to the plane where the second substrate is located. The warping phenomenon of the film layer at the first light-transmitting hole can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique [0002] From the CRT (Cathode Ray Tube, cathode ray tube) era to the liquid crystal era, and now to the O backlight (Organic Light-Emitting Diode, organic light-emitting diode) era, the display industry has experienced decades of development and has become ever-changing. The display industry has been closely related to our lives. From traditional mobile phones, tablets, TVs and PCs to the current smart wearable devices and VR, display technology is inseparable. [0003] In order to meet the needs of users for using display devices, more and more display devices have a fingerprint recognition function. Usually, when the display panel is touched, the light reflected by the touch body will be transmitted to the fingerprint identification unit through the light transmission hole on the display panel, and t...

Problems solved by technology

In the prior art, materials with different expansion coefficients are stacked around the light-transmitting hole. During the production process, when materials with different expansion coefficients are stacked on each other, stress will occur between different materials, causing warping of these materials. , resulting in warpage of the substrate carrying these materials in the display panel, which in turn causes warpage of the entire display panel, affecting the production yield of the display panel
