Display panel and display device

Abstract

The invention provides a display panel and a display device, and the display panel comprises a substrate, a first electrode layer, a pixel defining layer, a light-emitting layer, a second electrode layer, a packaging layer, a black matrix, a color film layer, a covering layer, a reflection reducing function layer, and an optical adhesive layer. The first electrode layer and the pixel defining layer are arranged on one side of the substrate; the light-emitting layer is arranged on the side, deviating from the substrate body, of the first electrode layer, the second electrode layer covers the sides, deviating from the substrate body, of the pixel defining layer and the light-emitting layer, the packaging layer is arranged on the side, deviating from the substrate body, of the second electrode layer, and the black matrix and the color film layer are arranged on the side, deviating from the substrate body, of the packaging layer; the covering layer covers the sides, deviating from the underlayer substrate, of the black matrix and the color film layer, the reflection reducing functional layer is arranged on the side, deviating from the underlayer substrate, of the covering layer and configured to reduce the reflectivity of external incident light, and the optical adhesive layer is arranged on the side, deviating from the underlayer substrate, of the reflection reducing functional layer. According to the display panel provided by the invention, the overall reflectivity of a product can be reduced.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of terminal technology, the screen size of electronic devices is getting larger and larger, and electronic devices with a high screen-to-body ratio are gradually favored by users. As the ultimate development of high-screen-to-body electronic devices, full-screen electronic devices maximize the screen ratio of electronic devices. It is one of the most popular technologies at present and is loved and sought after by users. In order to keep the fingerprint collection module on the display surface of the electronic device and avoid affecting the screen-to-body ratio of the electronic device, an under-screen fingerprint recognition method is proposed in the prior art to realize the fingerprint recognition function. Compared with the traditional fingerprint recognition module, the f...

Problems solved by technology

[0003] However, when the under-screen fingerprint recognition technology is applied to an organic light-emitting display (Organic Light-Emitting Diode, OLED) based on COE (CFon EL, a color filter layer is formed on a thin-film-encapsulated organic electroluminescent device), due to the black matrix ( Black Matrix, BM), color filter layer (Color Filter, CF) and the shielding of the electrode layer, the light transmittance of the COE-based OLED is very low, which cannot meet the transmittance requirements for fingerprint recognition under the screen
