Problems solved by technology

[0002] The display surface of bendable wearable consumer electronics products is generally composed of a glass cover and a protective film. The protective film is usually selected as a PI film, that is, a polyimide film; the protective film mainly serves to protect the glass cover. Function, when the glass cover plate is cracked by impact, the glass cover plate will be bonded to the protective film, and the glass will not hurt people, but because the glass cover plate needs to be bendable in bendable wearable products, The glass material should not be too thick, resulting in low glass strength. When the glass encounters a relatively strong impact, the glass will crack

Abstract

The invention relates to the technical field of screen processing, in particular to a display screen assembly, a preparation method of the display screen assembly and a display terminal. The display screen assembly comprises a display screen, a first polyimide film and a second polyimide film, wherein the first polyimide film comprises, by weight, the following raw material components: 80-130 parts of polyimide resin micro powder, 1-3 parts of EDTA chelated manganese, 3-6 parts of silicon nitride micro powder, 10-15 parts of a curing agent and 7-15 parts of bentonite; and the second polyimidefilm is adhered on the surface of the first polyimide film and is prepared through electrodeposition. According to the invention, two layers of polyimide films are combined together to replace the combination of a protective film and a front glass cover plate. The technical problem that the glass cover plate in the display screen in a bendable wearable product is easy to crack, the PI film is a bendable plastic film material, has good mechanical property, has the advantages of low temperature resistance, low expansion coefficient, flame retardance, good biocompatibility and the like, and meetsthe property of replacing the glass cover plate.
