Toughened glass unit and manufacturing method and cover plate having toughened glass unit

Abstract

The invention relates to a toughened glass unit and a manufacturing method and a cover plate having the toughened glass unit, the method for preparing the toughened glass unit comprises the following steps: providing a glass base material at first, wherein the glass base material comprises a plurality of glass unit predetermined areas. removing partial glass base material at outer circumference of each glass unit predetermined area, forming at least a trench and at least a connecting bridge at the edge of each glass unit predetermined area, wherein the circumference section of each glass unit predetermined area is exposed from the trench, and the glass unit predetermined area forms an entire sheet of patterning glass base material by the connecting bridge. The entire sheet of patterning glass base material is performed a reinforcement process so that a reinforcement section is formed at the circumference section exposed on the glass unit predetermined area. The connecting bridge is removed, and the glass unit predetermined areas having the reinforcement section are separated from each other to form a plurality of the reinforcement glass units.

Description

technical field [0001] The present invention relates to a glass unit, a manufacturing method thereof and a cover board, in particular to a strengthened glass unit, a manufacturing method thereof and a cover board having the strengthened glass unit. Background technique [0002] Today, display panels are widely used, and many display panels are used in various portable electronic products, such as personal digital assistants (PDAs), mobile phones, and tablet PCs. Since most of these portable electronic products have touch functions and are prone to fall during carrying or use, the strength of the glass substrate of the display panel needs to be strengthened. [0003] In the prior art, a method for manufacturing strengthened glass is as follows: First, the glass base material is cut into many small pieces of glass units. Next, an edge grinding step is performed on each of these small pieces of glass units. These small pieces of glass units are then individually subjected to ...

AI Technical Summary

Problems solved by technology

At present, in the process of cutting the strengthened glass base material, often due to the high strength of the strengthened glass base material, the strengthened glass base material is prone to burst points and rupture during the cutting process, which leads to a decrease in the yield of strengthened glass. The small piece of glass unit produced by this process is directly used as the final product. Since the new section cut out on the cutting line in the small piece of glass unit is not exposed in the step of strengthening processing, the new section of the small piece of glass unit not strengthened

As a result, in subsequent processes such as edging and chamfering, these small pieces of glass units are prone to produce many tiny cracks on their edges, which will greatly reduce the strength of the glass and easily lead to damage such as cracking of the final product
