Abstract

A substrate and cut-cracking method thereof, capable of accelerating substrate cut-cracking speed, and reducing obliquity and offset after the cut-cracking, thus reducing the misjudgment of an inspection machine, and alleviating the burden on workers. The cut-cracking method comprises: forming an etched groove on the first surface (101) of a first substrate (10) and the first surface (201) of a second substrate (20) respectively; aligning and fitting the first surface (101) of the first substrate (10) with the first surface (201) of the second substrate (20) along the etched groove; on the second surface (102) of the first substrate (10) and the second surface (202) of the second substrate (20), using a knife flywheel to cut the first substrate (10) and the second substrate (20) respectively along the cutting line, such that the cutting-formed vertical cracks extend to the etched groove (30), thus cutting the first substrate (10) off the second substrate (20).

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel manufacture, in particular to a substrate and a cutting method thereof. Background technique [0002] In the prior art, the cutting of liquid crystal substrates mostly adopts the method of knife wheel cutting, please refer to figure 1 and figure 2 , figure 1 It is a schematic diagram of the principle of the cutting method of the substrate in the prior art, figure 2 It is a schematic diagram of the cross-sectional structure after the substrate is cut in the prior art. The cutting method is specifically as follows: using the cutter wheel 100 to apply pressure to one side of the substrate 200, causing the surface to be damaged to form rib-shaped cracks 300, the rib-shaped cracks 300 are divided into horizontal cracks 301 and vertical cracks 302, and then the substrate 200 Pressure is applied to the surface of the other side to extend the vertical crack 302 ( figure 1 middle dotted...
