Method for cutting tempered glass and preparatory tempered glass structure |
摘要 |
A preparatory tempered glass structure for a cutting treatment includes a glass substrate and at least one trench. The glass substrate is given a strengthening treatment to form, from a surface to the inside of the glass substrate, at least one compression stress layer and a tensile stress layer corresponding to the compression stress layer. The trench is formed in the compression stress layer of the glass substrate and overlaps a predetermined cutting path for the cutting treatment. |

1. A preparatory tempered glass structure for a cutting treatment, comprising:
a glass substrate given a strengthening treatment to form, from a surface to the inside of the glass substrate, at least one compression stress layer and a tensile stress layer corresponding to the compression stress layer, wherein the glass substrate has a bottom surface and a top surface opposite the bottom surface; a first trench formed on the top surface and in the compression stress layer of the glass substrate without splitting the glass substrate to remove a part of the compression stress layer and correspondingly reduce a tensile stress along the first trench; a second trench formed on the bottom surface and in the compression stress layer of the glass substrate without splitting the glass substrate to remove a part of the compression stress layer and correspondingly reduce a tensile stress along the second trench; and a scribe line formed in the first trench or the second trench to initiate the cutting treatment and define a cutting path for the cutting treatment. |
