Abstract

The invention provides a base plate and an edging detection method, alignment method and device thereof. The base plate comprises a substrate base plate body and at least one edging detection figure arranged on the substrate base plate body. The edging detection figure is arranged at the edge of the substrate base plate body and made of electrically conductive materials. Due to the fact that the edging detection figure is arranged at the edge of the substrate base plate body and made of the electrically conductive materials, after the base plate is subjected to edge grinding, the abrasion degree of the edging detection figure can be determined by detecting the resistance of the edging detection figure, and thus the abrasion degree of the base plate is determined. Compared with the prior art, the edge grinding detection method is more accurate, an implement method is simple, and the cost is low.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a substrate and its edge grinding detection method, alignment method and device. Background technique [0002] When the size of the glass substrate used to make the display device is large and does not match the size required by the equipment in the subsequent process, the glass substrate needs to be cut first. After the glass substrate is cut, there will be more burrs on the edge. The glass substrate is edged to prevent damage to the glass in subsequent processes. [0003] In the existing technology, the effect of edging the glass substrate is often judged by experienced engineers with the naked eye, so there is a large error, which will cause great difficulties in the alignment of the subsequent process, occupy the machine table, and waste machine time , reducing production efficiency. Contents of the invention [0004] In view of this, the present invention provides a sub...
