Embodiment Construction
[0030] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0031] Such as Figure 6 As shown, the method for repairing cracks in the substrate according to the embodiment of the present invention specifically includes the following steps:
[0032] Step S1 , coating the cracks on the surface of the ultra-thin glass substrate with an adhesive, and diffusing into the cracks of the ultra-thin glass substrate through capillary action. Such as image 3 As shown, the adhesive 5 located on the surface of the ultra-thin glass substrate and the adhesive 4 located at the crack are finally formed.
[0033] The binder in the embodiment of the present invention is epoxy resin, acrylic resin or garlic juice. Among them, the viscosity range o...

Abstract
The invention relates to the technical field of glass substrate production, in particular to a method for repairing a crack of a glass substrate. The method includes the steps that firstly, the crack part of the surface of the glass substrate is coated with a bonding agent, and the bonding agent is made to permeate into the crack of the glass substrate; secondly, the part, coated with the bonding agent, of the glass substrate is subjected to curing treatment so that the parts, on the two sides of the crack, of the glass substrate can be bonded together; thirdly, a protecting layer is arranged at the crack part, treated in the second step, of the glass substrate. According to the method for repairing the crack of the glass substrate, the bonding agent is made to permeate into the crack through the capillary action to act together with small-power laser welding on the crack part of the glass substrate, the parts, at the two ends of the crack, of the ultra-thin glass substrate can be effectively bonded, and the roughness of the crack on the glass surface is greatly reduced, so that propagation of the crack is prevented, the utilization rate of the ultra-thin glass substrate is increased, and production cost is reduced.
Description
[0001] The patent application of the present invention is a divisional application of the Chinese invention patent application with the filing date of August 8, 2011, the application number of 201110226088.5, and the title of "a method for repairing cracks in glass substrates". technical field [0002] The invention relates to the technical field of producing glass substrates, in particular to a method for repairing cracks in glass substrates. Background technique [0003] In recent years, with the rapid development of flat panel display technology, people's requirements for the display performance of the display are also increasing. Due to its good bending characteristics, flexible display devices can be used in many fields that require curved surface display, such as smart cards, electronic paper, smart labels and other fields. These areas are increasingly sought after by many consumers. [0004] At present, flexible display characteristics generally come from display dev...
