Screen protection film and electronic equipment

Abstract

The embodiment of the invention provides a screen protection film and electronic equipment. The screen protection film is used for fitting a display screen module; one side, facing away from the screen protection film, of the display screen module is provided with an ultrasonic fingerprint module; the screen protection film can penetrate ultrasonic waves emitted by the ultrasonic fingerprint module; the screen protection film is provided with a resonance layer; the resonance layer is provided with a first surface adjacent to the ultrasonic fingerprint module and a second surface opposite to the first surface; the resonance layer can enable ultrasonic waves emitted from the first surface towards the second surface and ultrasonic waves reflected from the second surface towards the first surface to be superimposed so as to generate resonance. The thickness of the screen protection film does not need to be compressed to reduce ultrasonic attenuation, so that the ultrasonic penetration property, fitting property and mechanical property of the screen protection film can be achieved.

Description

technical field [0001] The application relates to the technical field of protective films, in particular to a screen protective film and electronic equipment. Background technique [0002] At present, mobile phones are usually attached with a screen protector to prevent the screen of the mobile phone from being scratched. Some mobile phones are equipped with ultrasonic fingerprint recognition devices. The ultrasonic waves emitted by ultrasonic fingerprint recognition devices are mechanical waves. The above-mentioned ultrasonic waves are easy to attenuate in the screen protective film. Usually, the thickness of the screen protective film needs to be reduced as much as possible to minimize the loss of ultrasonic waves. However, it will lead to a decline in the overall performance of the screen protector and weaken the protective function of the screen. Contents of the invention [0003] The embodiment of the present application also provides a screen protection film, the sc...
