Abstract

The invention provides a display panel, a preparation method thereof and a display device. The display panel comprises a plurality of display units arranged on a substrate at intervals; wherein each display unit comprises at least one pixel; the reflecting layer is positioned on the substrate and is arranged between any two adjacent display units; the scattering layer is arranged on one side, far away from the substrate, of the reflecting layer; wherein the scattering layer at least partially transmits light, and the orthographic projection of the scattering layer on the substrate at least covers the orthographic projection of the reflecting layer on the substrate. The part, irradiated on the scattering layer, of laser incident on the display panel is firstly scattered by the scattering layer, and then the scattered laser is reflected by the reflecting layer, so that the diffuse reflection of the laser at each visual angle is increased, Lambert-like light spots are formed, the laser can be seen at each visual angle, and the full-visual-angle visibility of the laser pen on the display panel is realized.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] At present, in various teaching, lecture or conference occasions, projectors are usually used to project projection materials onto screens and walls, but the projectors have problems of low contrast and poor image quality. With the wide application of large-size displays, liquid crystal display panels (LCD, Liquid Crystal Display) and organic light-emitting diodes (Organic Light-Emitting Diode, OLED), as well as micro light-emitting diodes (Micro Light Emitting Diode, referred to as Micro LED) and submillimeter Light emitting diode (Mini Light Emitting Diode, mini LED for short) technology is gradually applied to various electronic devices, including conference display equipment. [0003] These display devices have the advantages of high contrast and good image quality...
