Embodiment Construction

[0034] In order to make the purpose, technical solution and effect of the present application more clear and definite, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0035] The present application provides a display panel, which can be used in various display modes, such as OLED display, quantum dot display, Micro-LED display and the like. Here, OLED display is taken as an example for illustration, but is not limited to this display mode.

[0036] see figure 1 , figure 1 It is a schematic cross-sectional structure diagram of an embodiment of the display panel of the present application. In this embodiment, the display panel includes a substrate 10 , support pillars 40 , at least one organic buffer layer 50 , at least one hard protective layer 60 and an encapsulation film layer group 70 . Specifically, the support column 40 is located on one side surface of the substrate 10; at least one organic b...

Abstract

The application discloses a display panel, a piece of display equipment and a preparation method of the display panel. The display panel includes a substrate, support pillars located on the surface ofone side of the substrate, at least one organic buffer layer at least located on the surfaces of the sides of the support pillars away from the substrate, at least one hard protective layer at leastlocated on the surfaces of the organic buffer layers on the surfaces of the support pillars, and a package film layer group located on the side of the hard protective layers away from the organic buffer layers and at least fully covering the support pillars. The package film layer group at least includes an inorganic package film layer. The hardness of the hard protective layers is higher than that of the inorganic package film layer. Through the scheme, the film packaging reliability of the display panel can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a display device, and a method for preparing a display panel. Background technique [0002] Organic light-emitting diodes (Organic Light-Emitting Diode, OLED) have the advantages of self-luminescence, fast response, high contrast, wide viewing angle, etc., and have received extensive attention in recent years. Because the luminescent material is easily damaged by water vapor and oxygen, in order to prevent water and oxygen from contacting and corroding the OLED luminescent material, it is usually necessary to use thin film encapsulation (TFE) to encapsulate the OLED device. In the long-term research and development process, the inventor of the present application found that the inorganic layer used to block water vapor in the thin-film packaging layer would be destroyed, resulting in the failure of the thin-film packaging, allowing water and oxygen to ...
