Abstract

The invention provides a protective film. The protective film comprises a bonding layer and a base film layer which are arranged in a stacked mode, the bonding layer is used for being bonded to a foldable display screen, the base film layer comprises one or more high-modulus base films and one or more low-modulus base films, the elastic modulus of the high-modulus base films is larger than that of the low-modulus base films, the high-modulus base film and the low-modulus base film are alternately stacked, and the surface layer, far away from the bonding layer, in the base film layer is the high-modulus base film. The protective film disclosed by the invention can be firmly attached to the foldable display screen and cannot be warped due to rebounding caused by repeated bending of the display screen, so that the foldable display screen is comprehensively and effectively protected. The invention further provides a protective film assembly comprising the protective film, a display screen assembly and a terminal.

Description

technical field [0001] The present application relates to the technical field of terminals, in particular to a protective film, a protective film assembly, a display screen assembly and a terminal. Background technique [0002] With the wide application of terminals such as mobile phones, the protection requirements are getting higher and higher, and a protective layer is often attached to the display screen of the terminal to prevent the display screen from being damaged and polluted. However, during the use of the foldable terminal, the traditional protective film will be warped due to multiple bending and rebound, which cannot provide comprehensive and effective protection for the display screen. Contents of the invention [0003] The present application provides a protective film, which is firmly attached to a foldable display screen, prevents the protective film from being lifted due to repeated bending and rebound, and comprehensively and effectively protects the fol...
