Abstract

The invention relates to a packaging structure, a display panel and a preparation method thereof, wherein the packaging structure comprises a cover plate substrate and a titanium dioxide composite film layer arranged on the cover plate substrate, and the titanium dioxide composite film layer is a porous titanium dioxide film loaded with a drying material. The packaging structure and the display panel not only can protect the light-emitting device from being influenced by the ultraviolet light, but also do not influence the light emitting of the light-emitting device.

Description

technical field [0001] The invention relates to the technical field of electronic display, in particular to a packaging structure, a display panel and a preparation method thereof. Background technique [0002] Organic light-emitting diodes (OLEDs) have been widely used in the fields of new-generation mobile phone screens, computer monitors, and full-color TVs due to their advantages such as self-illumination, wide viewing angle, high contrast ratio, and low power consumption. Compared with conventional LCDs, OLEDs do not require a backlight, and these organic materials emit light when current passes through the organic functional layers. In this way, the thickness and power consumption of the display screen can be greatly reduced. However, organic light-emitting materials are very easy to react with water and oxygen, resulting in black spots in pixels and affecting the display effect. Therefore, optimizing the structure of OLED display panels to block water and oxygen is c...
