技术领域Technical field

本申请涉及电子设备技术领域，特别涉及一种电子设备、显示屏、玻璃盖板及玻璃盖板的制造方法。This application relates to the technical field of electronic equipment, and in particular to a manufacturing method of electronic equipment, display screens, glass cover plates and glass cover plates.

背景技术Background technique

智能终端显示屏的玻璃盖板通常包含氟醚类耐指纹(anti-fingerprint,AF)层，氟是已知元素中非金属性最强的元素，具有极大电负性，且氟具有极小的原子半径，捕获电子能力极强，故在撕膜或摩擦等条件下，玻璃表面的AF层极易产生静电。而玻璃一般是绝缘体，表面电阻超过1×10 ¹²欧姆，不易释放静电，这样在显示屏的装配制程中容易发生静电释放(electro static discharge，ESD)现象，产生的静电放电电压可能击穿显示模组的集成电路或者引脚，同时还会影响液晶取向，导致黑屏、花屏、静电横纹等显示问题，严重影响用户体验度和产品的声誉，此外，玻璃盖板的表面产生静电以后，由于静电感应现象还会产生脏污吸附的问题。 The glass cover of the smart terminal display usually contains a fluoroether anti-fingerprint (AF) layer. Fluorine is the most non-metallic element among the known elements. It has great electronegativity, and fluorine has very little The atomic radius of, the ability to capture electrons is very strong, so under conditions such as tearing or rubbing, the AF layer on the glass surface is very easy to generate static electricity. The glass is generally an insulator with a surface resistance of more than 1×10 ¹² ohms, and it is not easy to discharge static electricity. In this way, electrostatic discharge (ESD) is prone to occur during the assembly process of the display screen, and the generated electrostatic discharge voltage may break down the display module. The integrated circuit or pin of the group will also affect the orientation of the liquid crystal, resulting in black screen, blurred screen, static horizontal stripes and other display problems, which will seriously affect the user experience and product reputation. In addition, after static electricity is generated on the surface of the glass cover, due to static induction The phenomenon will also cause the problem of dirt adsorption.

发明内容Summary of the invention

本申请提供一种电子设备、显示屏、玻璃盖板及玻璃盖板的制造方法，能够降低静电放电电压，有效避免显示屏的黑屏、花屏、静电横纹等显示问题。The present application provides a method for manufacturing electronic equipment, display screens, glass cover plates, and glass cover plates, which can reduce electrostatic discharge voltage and effectively avoid display problems such as black screens, blurred screens, and horizontal static stripes of the display screen.

第一方面，提供一种电子设备，该电子设备包括显示屏，显示屏包括玻璃盖板和显示模组，玻璃盖板安装于显示模组上，该玻璃盖板包括玻璃基板和防静电层，防静电层设置于玻璃基板上，所述防静电层的表面电阻为1.0×10 ⁵～1.0×10 ¹²欧姆。 In a first aspect, an electronic device is provided, the electronic device includes a display screen, the display screen includes a glass cover plate and a display module, the glass cover plate is mounted on the display module, the glass cover plate includes 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 to 1.0×10 ¹² ohm.

本申请提供的电子设备的玻璃盖板包括防静电层，并且该防静电层的表面电阻要小于玻璃基板的表面电阻(即防静电层的导静电能力更强)，静电通过该防静电层能够及时的向空气中水汽、人体或其他导体进行泄放，避免在玻璃盖板表面积累静电荷，从而防止黑屏、花屏、静电横纹等显示问题。此外，由于及时的进行静电泄放，还能够减轻由于静电吸附而产生的脏污吸附的问题。The glass cover plate of the electronic device provided in this application includes an antistatic layer, and the surface resistance of the antistatic layer is smaller than the surface resistance of the glass substrate (that is, the antistatic layer has stronger electrostatic conductivity), and static electricity can pass through the antistatic layer.

The selection of this range can better take into account the above two aspects, that is, the antistatic ability of the glass cover can be improved as much as possible on the premise that the touch and radio frequency performance of the electronic device will not be greatly affected.

FIG. 4 is a front view of an example in which an antistatic ink layer is provided on the back of the glass substrate 211. In this embodiment, the glass substrate 211 is composed of a window area and a non-window area. The window area can be understood as a transparent area through which light needs to pass, such as the first area 211A facing the display module 220 and the second area 211B facing the camera in FIG. 4. The non-window area can be understood as a non-transparent area that does not require light to pass through. For example, the non-window area 211C in FIG. 4 is easy to understand. When installed, the non-window area 211C can face the frame of the electronic device 500 and be attached to it. Above the border.

应理解，在其他实施例中，玻璃基板211可以只包括视窗区域(例如对一些全面屏手机)，本申请对此不做限定。It should be understood that in other embodiments, the glass substrate 211 may only include the window area (for example, for some full-screen mobile phones), which is not limited in this application.
