Problems solved by technology

Glass is generally an insulator, and its surface resistance exceeds 1×10 12 Ohm, it is not easy to discharge static electricity, so it is prone to electrostatic discharge (electro static discharge, ESD) phenomenon in the assembly process of the display screen, and the generated electrostatic discharge voltage may break down the integrated circuit or pin of the display module, and at the same time affect the liquid crystal display. Orientation, leading to display problems such as black screen, blurred screen, static horizontal stripes, etc., seriously affecting user experience and product reputation. In addition, after static electricity is generated on the surface of the glass cover, the problem of dirt adsorption will also occur due to electrostatic induction.

Abstract

The invention provides electronic equipment, a display screen, and a glass cover plate and a manufacturing method thereof, wherein the electronic equipment comprises the display screen, the display screen comprises the glass cover plate and a display module, the glass cover plate is installed on the display module, and comprises a glass substrate and an antistatic layer, the antistatic layer is arranged on the glass substrate, and the surface resistance of the antistatic layer is 1.0*10<5>-1.0*10<12> ohm. According to the present invention, the glass cover plate comprises the antistatic layer,the surface resistance of the antistatic layer is smaller than the surface resistance of the glass substrate (ie., the antistatic layer has high static conductivity), and static electricity can be discharged to water vapor in air, a human body or other conductors in time through the antistatic layer, such that the static charges can be prevented from being accumulated on the surface of the glasscover plate so as to prevent the display problems of black screen, blurred screen, static transverse lines and the like, and the problem of dirt adsorption caused by electrostatic adsorption can be relieved.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to an electronic equipment, a display screen, a glass cover and a method for manufacturing the glass cover. Background technique [0002] The glass cover of the smart terminal display usually contains a fluoroether anti-fingerprint (AF) layer. Fluorine is the most non-metallic element among known elements, with extremely high The atomic radius is extremely strong, and the ability to capture electrons is extremely strong, so the AF layer on the glass surface is prone to static electricity under conditions such as tearing the film or friction. Glass is generally an insulator, and its surface resistance exceeds 1×10 12 Ohm, it is not easy to discharge static electricity, so it is prone to electrostatic discharge (electro static discharge, ESD) phenomenon in the assembly process of the display screen, and the generated electrostatic discharge voltage may break do...
