Problems solved by technology

[0002] At present, when the mobile phone screen is installed, a layer of cushioning material needs to be installed at the junction of the mobile phone screen and the mobile phone body to achieve a buffering effect on the mobile phone screen. Most of the cushioning materials have poor viscosity. When installing the mobile phone screen, the mobile phone screen not only needs cushioning The buffer performance of the mobile phone is also very high for its viscosity. The viscosity of the mobile phone installation buffer material in the prior art cannot meet the needs of actual installation, resulting in poor performance of the mobile phone screen during the use of the mobile phone. Therefore, it is urgent to design a mobile phone screen Installing Viscosified Cushioning Materials to Solve Problems in the Prior Art
