Title:
GLASS COVER PLATE AND PREPARATION METHOD THEREFOR, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/032061
Kind Code:
A1
Abstract:
The present application relates to the technical field of electronic devices, and in particular, to a glass cover plate and a preparation method therefor, and an electronic device. The glass cover plate comprises a glass substrate and an optical film layer; the refractive index of the optical film layer is 1.46-1.62; the optical film layer comprises a first material and a second material which are atomically mixed; the mass ratio of the first material to the second material is (1-8):1; and the refractive index of the first material is greater than 1.6, and the refractive index of the second material is less than 1.52. According to the glass cover plate of the present application, the first material having a refractive index higher than that of the glass substrate and the second material having a refractive index lower than that of the glass substrate are atomically mixed to form the optical film layer, the optical film layer has a refractive index approximate to that of the glass substrate and thus would not affect the light transmittance and reflection rate of the glass substrate, and the refractive index of the optical film layer would not change along with the change in the thickness; when the optical film layer is formed on a glass substrate having a curved edge, the change in the thickness of the film layer would not cause color difference in the appearance of the glass substrate; in addition, the appearance of the glass cover plate would not change when the film layer falls off.
