Glass Cover and Preparation Method Therefor and Electronic Device

Abstract

This application relates to a glass cover and a preparation method therefor and an electronic device. The glass cover includes a glass substrate and an optical film layer, and a refractive index of the optical film layer is 1.46˜1.62. The optical film layer includes a first material and a second material that are atomic-level mixed, a mass ratio of the first material to the second material is (1˜8):1, a refractive index of the first material>1.6, and a refractive index of the second material<1.52. In the glass cover in this application, the first material whose refractive index is greater than that of the glass substrate and the second material whose refractive index is less than that of the glass substrate are mixed to form the optical film layer. The refractive index of the optical film layer is close to that of the glass substrate.
