Display panel and display device

By integrating the light-emitting element and the photosensitive element into the same film layer structure in the display panel, the problems of excessive thickness and poor bending performance of foldable screens are solved, achieving a thin design and excellent bending performance, while also improving fingerprint recognition and touch sensing effects.

Abstract

This application provides a display panel and a display device, relating to the field of display technology. The display panel includes a substrate; a light-emitting element located on one side of the substrate; a photosensitive element located on the same side of the substrate as the light-emitting element; and a touch electrode located on the side of the photosensitive element away from the substrate. The display panel includes a light-emitting area and a non-light-emitting area, with the light-emitting element corresponding to the light-emitting area and the photosensitive element located in the non-light-emitting area. By placing the light-emitting element and the photosensitive element in the display panel on the same side of the substrate, and setting the light-emitting element in the light-emitting area and the photosensitive element in the non-light-emitting area, the light-emitting element and the photosensitive element are disposed on the same film layer substrate, avoiding excessive increase in the film layer thickness of the display panel due to separate film layer substrates, and also mitigating the problem of deteriorated overall bending performance of the display panel caused by separate film layer placement of the photosensitive element.
