Abstract

The invention provides a display substrate, a display device, and a manufacturing method of the display substrate, belonging to the field of display technology, which can at least partially solve the problem of low photoelectric conversion efficiency when integrating a photoelectric conversion layer in an existing liquid crystal display panel. The display substrate of the present invention comprises a base, the base is divided into a pixel light emitting area and a non-light emitting area, a photoelectric conversion layer is arranged on one side of the base, the orthographic projection of the photoelectric conversion layer on the base is located in the non-light emitting area, and the photoelectric conversion layer is backed. The polarizing structure is arranged on one side of the substrate, and the side of the substrate facing away from the polarizing structure is the display surface.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display substrate, a display device, and a manufacturing method of the display substrate. Background technique [0002] In the prior art, there are solutions for integrating the photoelectric conversion layer in the color filter substrate of the liquid crystal display panel. That is, the photoelectric conversion layer is integrated on the side of the color filter substrate facing the liquid crystal layer, and the polarizer is attached to the side of the color filter substrate away from the liquid crystal layer. The liquid crystal display panel constructed in this way can not only realize liquid crystal display, but also realize power generation by utilizing ambient light such as sunlight or lights in the natural environment, thereby realizing the purpose of reducing power consumption. In order not to affect the display, the photoelectric conversion layer is usuall...
