Protective film for screen

Abstract

A disclosed protective film for a screen comprises a protective film body and a frame body, the protective film body is connected to the frame body, positioning assemblies are arranged at the four corners of the protective film body correspondingly, the four positioning assemblies are matched with the four corners of the protective film body correspondingly, the four positioning assemblies are arranged on the frame body correspondingly, and the four corners of the frame body are fixedly wrapped with clamping mechanisms correspondingly. According to the protective film for the screen, a dampinglayer, multiple buffer blocks and multiple buffer grooves are used for achieving a certain buffer effect on the film body, the edge of the film body is prevented from being damaged due to strong extrusion, the protective film does not need to be bonded to the display screen in the later period, installation is more convenient, meanwhile, the frame body can extrude the protective film, thus the connection between the protective film and the display screen is tighter, the protective film is prevented from loosening, the use effect of the protective film is ensured, and the protective film is more convenient to install.

Description

technical field [0001] The invention relates to a protective film for screens, belonging to the technical field of protective films. Background technique [0002] A liquid crystal display (LCD) is a type of display used in digital timepieces and many portable computers. The LCD display uses two sheets of polarized material with a liquid crystal solution between them. When an electric current is passed through this liquid, it rearranges the crystals so that light cannot pass through them. Thus, each crystal acts like a shutter, both allowing light to pass through and blocking it. Liquid crystal displays (LCDs) are currently developing towards the goal of being light, thin, short and small, and display products with a long history in computer peripherals are no exception. Under the premise of being easy to carry and transport, traditional display methods such as CRT image tube monitors and LED display panels are all subject to factors such as excessive size or high power co...

AI Technical Summary

Problems solved by technology

[0003] At present, when installing the protective film, usually only adhesive glue is used for bonding. After a long time, the viscosity of the adhesive glue will decrease, especially in the weather where the temperature is too high, the viscosity of the adhesive glue will become worse. As a result, the stability of the protective film is reduced, and the protective film becomes loose, which affects the use effect of the protective film. When the device is accidentally dropped, the protective film and the display screen of the device are directly impacted and easily damaged
