Embodiment Construction

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0031] In the existing display panels, the OLED luminescent material is mainly protected by the filtering effect of the polarizer, but the existing polarizer cannot completely filter the ultraviolet light in the 380-420nm band, which causes the OLED luminescent material to be damaged under sunlight, affecting The lifespan of the display panel. The application proposes the following technical solutions based on the above-mentioned technical problems:

[0032] see Figure 1 to F...

Abstract

The invention provides a display panel and a display device. The display panel comprises a substrate, a light-emitting functional layer located on the substrate, a coupling light-emitting layer located on the light-emitting functional layer, and a Bragg reflection layer located on the coupling light-emitting layer. According to the invention, the Bragg reflection layer is arranged on the coupling light emitting layer, and the Bragg reflection layer is periodically provided with the high-low refractive index layer doped with the ultraviolet light absorber, so that the damage of external ultraviolet light to the material of the light emitting functional layer is reduced, the display life of the display panel is prolonged, the eye protection function of the display panel is enhanced, and the market competitiveness of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display panels, in particular to a display panel and a display device. Background technique [0002] Compared with Liquid Crystal Display (LCD), Organic Light Emitting Diode (OLED) display panel has the advantages of self-illumination, fast response, wide viewing angle, high brightness, bright color, light and thin, etc. One of the technology hotspots. [0003] However, the organic small molecule materials used in OLED devices are extremely sensitive to water vapor, oxygen, and high-energy ultraviolet light. Prolonged exposure to high-energy ultraviolet light will cause the chemical bonds of the organic small molecule materials to break, thereby affecting the luminescence performance of OLEDs. AMOLED mobile phone products inevitably have outdoor use scenarios. The ultraviolet components in outdoor sunlight will cause irreversible damage to AMOLED organic light-emitting materials, thereby changing the col...
