Abstract

The invention relates to the technical field of display, and discloses a display panel and a display device. The display panel comprises a substrate, and a polycrystalline silicon active layer, an electrode layer and a planarization layer arranged on the substrate, wherein the planarization layer covers the polycrystalline silicon active layer and the electrode layer, and the electrode layer is arranged between the polycrystalline silicon active layer and the planarization layer; a light-emitting layer is arranged on the surface, away from the substrate, of the planarization layer, light emitted by the light-emitting layer serves as a projection line, the electrode layer forms a first projection on the substrate, the polycrystalline silicon active layer forms a second projection on the substrate, and the second projection is located in the first projection. Compared with the prior art, the display panel and the display device provided by the embodiment of the invention have the advantages that the occurrence of abnormal gray scale display is effectively reduced, and the display effects of the display panel and the display device are improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The optical fingerprint recognition AMOLED (Active-Matrix Organic Light-Emitting Diode, active-matrix organic light-emitting diode) display device mainly includes a TFT (Thin Film Transistor, thin-film transistor) array substrate and various functional layers of the AMOLED. Among them, for the TFT array substrate, according to the different materials of the active layer, the array substrate can be divided into amorphous silicon (amorphous-Silicon), low temperature polysilicon (Low Temperature Poly-Silicon, LTPS for short), high temperature polysilicon (High Temperature Poly-Silicon). Silicon, referred to as HTPS), oxide and other types. Among them, compared with other types of array substrates, the low-temperature polysilicon array substrate has the advantages of faster electron transfer rate, smaller t...
