Comprehensive functional membrane, manufacturing method thereof, and OLED display panel

Abstract

The invention provides a comprehensive functional membrane, a manufacturing method thereof, and an OLED display panel with the comprehensive functional membrane. The comprehensive functional membrane comprises a linear polarizer, a 1 / 4 wave plate and a touch membrane module with the obstructing function, wherein the linear polarizer comprises a linear polarization functional sheet layer and a hardening protecting layer arranged on the surface of one side of the linear polarization functional sheet layer, and the hardening strength of the hardening protecting layer is higher than the hardness 5H of a pencil; the 1 / 4 wave plate is arranged on the surface, far away from the hardening protecting layer, of the linear polarization functional sheet layer; the touch membrane module with the obstructing function is arranged on the surface, far away from the linear polarization functional sheet layer, of the 1 / 4 wave plate in a contact mode. The hardening strength of the hardening protecting layer of the linear polarizer is higher than the hardness 5H of a pencil, and therefore the hardening protecting layer can serve as a protective cap, a glass cover in the prior art is omitted, the thickness of the OLED display panel is reduced, and flexible packaging is achieved through the linear polarizer. The water-oxygen obstructing function, the touch function and the polarizing function are integrated, and therefore an adhering layer is omitted, the thickness of a packaging structure is reduced, the technological process is simplified, and the yield of finished products is guaranteed.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a comprehensive functional film, a manufacturing method thereof and an OLED display panel having the same. Background technique [0002] OLED is regarded as the most promising next-generation display technology, and flexible OLED devices are considered to be the development trend of OLED display. Due to being very sensitive to water vapor and oxygen, the organic materials used in OLED devices are easily oxidized or crystallized if exposed to the external environment, which seriously affects the performance of OLED devices. Therefore, it is necessary to effectively package the OLED device so that each functional layer of the OLED is not exposed to components such as water vapor and oxygen in the atmosphere. [0003] At present, the OLED display products on the market are all packaged with a glass cover to prevent water and oxygen erosion. The packaging effect can meet the requireme...
