Abstract

A preparation method of a touch screen comprises the following steps: strengthening a basal body of a whole piece of glass; forming a light shield layer and a conductive circuit on the strengthened glass basal body, followed by sand blasting processing, forming a groove on the surface with a stress layer; cutting the glass basal body along the groove to obtain a plurality of touch screens with pre-arranged shape. According to the invention, the surface stress layer at the position of the groove is removed, so that the cutting can not damage the stress layer of the glass, which maintains the strength of the glass to be approximately constant. Due to the adoption of the preparation method, after the completion of primary reinforcement, the touch screens can be obtained through cutting, and as a result, the production efficiency is greatly improved. The invention also provides another preparation method for the touch screen, and a panel glass and a preparation method thereof.

Description

technical field [0001] The invention relates to touch screen technology, in particular to a panel glass, a preparation method thereof and a touch screen preparation method using the panel glass. Background technique [0002] Tempered glass, also known as strengthened glass, is a kind of prestressed glass. A compressive stress layer is formed on the glass surface, and the glass itself has high compressive strength and will not cause damage. Due to its good light transmission and high strength, tempered glass has been widely used in construction, automobiles, furniture, solar cells, displays, touch screens, cameras and other fields. [0003] However, after the glass is strengthened, it cannot be cut or ground, and the corners cannot be hit and squeezed, otherwise the surface compressive stress layer will be destroyed, resulting in the disappearance of the strengthening effect. Therefore, when tempered glass is applied to the touch screen of electronic equipment, the general ...
