Example Embodiment

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not limit the present invention.

[0034] The cover glass used for electronic products was originally ordinary glass, and its surface has been ground and polished to meet the requirements of optical mirror surface, but the surface is very fragile. Because the touch screen panel glass is relatively thin, the surface flatness requirements are high, the forming is difficult, and the manufacturing process is much more complicated than ordinary flat glass. In the manufacturing process of the touch screen, the process from splitting, copying, and CNC (precision processing) Until polishing and other processes, it is easy to cause a certain degree of...

Abstract

The invention discloses a method for processing plate glass provided with a functional circuit. The method comprises the following steps: the functional circuit is made on a large polished and strengthened glass plate, the glass is covered with resin material which works as a protective film via screen printing technologies, the large glass is cut into single pieces of glass, and the single piecesof glass are laminated and then polished. According to the method, the resin protective film is used for replacing a hydrofluoric acid protective film; while a good protection function can be fulfilled, the environment-friendly resin protective film is easy to wash and poses no harm to humans. Via adoption of the resin material, operation procedures in a whole flow can be simplified, and production cost can be lowered.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a flat glass processing method with functional circuits. Background technique [0002] Glass plates with functional circuits, for example, touch screen circuits (OGS), are widely used in electronic products such as mobile phones and tablets. In order to prevent the damage of the glass when it falls, the common process is to use chemical products, such as potassium nitrate (KNO3) solution, for chemical strengthening treatment, and the mobile phone cover glass is also treated with this chemical strengthening method. The current representative OGS glass processing flow mainly has the following two methods: [0003] 1. Unstrengthened large plate glass → making surface protective film → cutting processing (cutting into a single piece of glass) → external peripheral grinding → cleaning → surface polishing → cleaning → chemical strengthening → cleaning → functional circuit pro...
