Protective film, display screen and electronic equipment

The invention provides a protective film, a display screen and electronic equipment. The protective film comprises a shear enhancement layer, wherein the shear enhancement layer comprises a first matrix and at least one of a shear thickening material and a shear hardening material which are added to the first matrix; each of the molecules of the shear thickening material and the molecules of the shear hardening material comprises two or more Si-O-B-(OH) 2 groups. The shear thickening material and the shear hardening material have the characteristic that the viscosity or the hardness is sharply increased when the shear thickening material and the shear hardening material are impacted by large external force. At least one of a shear thickening material and a shear hardening material is added to the protective film, and when the protective film is subjected to external impact, impact energy can be absorbed and conducted and dispersed in the extension direction of the layer structure. When the protective film is
