Abstract

The invention provides a display panel. The display panel comprises a substrate, a driving circuit layer located on the substrate, a light-emitting component located on the driving circuit layer, a protective layer located on the light-emitting component, and a diffusion layer located between the light-emitting component and the protective layer, wherein the diffusion layer uniformly guides lightemitted by the light-emitting component to the light-emitting side of the display panel. According to the display panel, the diffusion layer is arranged in the light-emitting unit, the point-shaped light source emitted by the light-emitting unit is diffused and uniformly guided out to the light-emitting side of the display panel, a technical problem that in the prior art, brightness of light spotsand the like of the point-shaped light source is not uniform is solved, and the display effect of a product is improved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel. Background technique [0002] In the full-color scheme of micro light emitting diode (Micro Light emitting diode, Micro LED) display device, it is mainly divided into the full-color scheme using red, green and blue three-color micro LED and the full-color scheme using blue light combined with a photoinduced conversion layer. solution. In the blue light chip combined with the light conversion layer solution, the light conversion layer uses quantum dot materials that require high absorption rate, narrow light spectrum and high luminous efficiency. [0003] In the existing high-resolution micro-LED display devices, the size of the sub-pixels is generally larger than that of the micro-light-emitting diode, and when the quantum dot film is formed on the micro-light-emitting diode, uneven phenomena such as dot-like spots will occur, reducing the product quality. display...
