WIPO Patent Application WO/2020/248803

A1

A cover plate (100), a manufacturing method for the cover plate, and an electronic device comprising the cover plate. The cover plate (100) comprises a glass substrate (110). A first surface (112) of the glass substrate is provided with a smooth area (112a) and a rough area (112b). The optical transmittance of at least a part of the smooth area (112a) of the glass substrate (110) is greater than 90%. The method for manufacturing the cover plate comprises the following steps: providing a glass substrate having a first surface (112) and a second surface (114) opposite each other; performing polishing treatment on the first surface and the second surface to make the optical transmittance of the glass substrate greater than 90%; forming an acid-resistant film on both the second surface and a part of the first surface; etching the area of the first surface where the acid-resistant film is not formed to form a rough area; and removing the acid-resistant film to obtain a cover plate. Further disclosed is an electronic device, the position of a camera lens corresponding to the position of the area of a glass substrate where the optical transmittance is greater than 90%.
