Problems solved by technology
Whether in the process of transmission or equipment process, there is a great risk of glass fragments, not only because of the cost loss caused by the fragments themselves, but also because of the fragments that may cause certain damage to the equipment, such as scratching the abutment or scratching Injured alignment pin (ie, alignment Pin)
[0004] Therefore, the technical solutions in the prior art still have room for improvement for detecting whether the glass is damaged in time.

Abstract
The disclosure provides a substrate to be detected, a method and equipment for detecting glass breakage, and belongs to the field of display technology. The substrate to be detected includes: a glass substrate and a layer of conductive film formed on the edge of the glass substrate. In the present disclosure, a layer of conductive film is first formed on the edge of the glass substrate, and then a preset current is input to one of the edges, and the current is detected on the edge to reflect the change of resistance, so as to judge the integrity of the edge of the glass substrate and the surrounding cracks. This detection method can detect the breakage of the glass substrate in time, reduce the process failure caused by the breakage and crack of the substrate, and further reduce the waste of time and materials caused by the subsequent process.
Description
technical field [0001] The present disclosure relates to the field of display technology, in particular, to a substrate to be detected, a method and equipment for detecting glass breakage. Background technique [0002] At present, thin glass is a new development trend in the display industry, but during the manufacturing process, the risk of glass fragmentation is also high due to the thickness of the glass being too thin. [0003] In the current technology, glass fragments can only be detected through the abnormal vacuum adsorption alarm of the equipment base, or glass fragments can be found by human eyes. No matter in the process of transmission or equipment process, there is a great risk of glass fragments, not only because of the cost loss caused by the fragments themselves, but also because of the fragments that may cause certain damage to the equipment, such as scratching the abutment or scratching Damage to the alignment needle (ie alignment Pin). [0004] Therefore...
