Display panel, fabrication method thereof and display device

Abstract

The invention discloses a display panel, a fabrication method thereof and a display device. The display panel comprises a substrate, a light-emitting layer and a light beam diffusion layer, wherein the light-emitting layer is arranged on the substrate, the light beam diffusion layer is arranged at one side of a light giving-out surface of the light-emitting layer, the light-emitting layer comprises a plurality of pixel units which are arranged in an array way, each pixel unit at least comprises a red light-emitting unit, a green light-emitting unit and a blue light-emitting unit, the light beam diffusion unit comprises a light beam diffusion component corresponding to at least one pixel unit, and the light beam diffusion component is used for expanding a giving-out light beam of the corresponding pixel unit. Since the light beam diffusion component in the light beam diffusion layer can be used for expanding the giving-out light beam of the corresponding pixel unit, the light giving-outarea of the display panel is expanded, the numbers of the light-emitting units are reduced, the power consumption of the display panel is reduced, so that the screen burnt rate of the display panel is reduced, moreover, the accuracy requirement of a mask is also reduced, and the large-size display panel is easier to fabricate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method and a display device. Background technique [0002] With the continuous development of display technology, organic electroluminescent (Organic Light-Emitting Diode, OLED) display is a future display technology direction that has attracted much attention. OLED displays have the advantages of self-illumination, full solid state, good mechanical properties, soft screen display, thinner, higher brightness, high-efficiency light emission, fast response, low-voltage drive and low power consumption, low cost, and less process. OLED displays can be divided into monochrome, multi-color, and full-color types according to color, among which the preparation of full-color OLED displays is the most difficult. Today, small-size OLED displays can be mass-produced. However, compared with small and medium-sized OLED displays using low-temperature polysilic...
