Abstract

The present application provides a display panel, which includes a substrate, a driving circuit layer on the substrate, a light emitting member on the driving circuit layer, a protective layer on the light emitting member, and a A diffusion layer between the light-emitting member and the protective layer, the diffusion layer guides the light emitted by the light-emitting member to the light-emitting side of the display panel uniformly. In the present application, by disposing a diffusion layer in the light-emitting unit, the point-shaped light source emitted by the light-emitting unit is diffused and evenly led out to the light-emitting side of the display panel, thereby eliminating the technical problem of uneven brightness of the point-shaped light source such as light spots in the prior art , which improves the display effect of the product.

Description

technical field [0001] The present application relates to the field of display, and in particular, to a display panel. Background technique [0002] In the full-color scheme of Micro Light Emitting Diode (Micro LED) display device, it is mainly divided into full-color scheme using red, green and blue micro LED and full-color scheme using blue light combined with photoconversion layer. ization plan. In the scheme of combining a blue light chip with a light conversion layer, the light conversion layer uses a quantum dot material that requires high absorptivity, narrow luminescence spectrum, and high luminous efficiency. [0003] In the existing high-resolution miniature light-emitting diode display devices, the size of the sub-pixels is generally larger than that of the miniature light-emitting diodes, and when the quantum dot film is formed on the miniature light-emitting diodes, uneven phenomena such as dot-shaped light spots will occur, reducing the product display qualit...
