Embodiment 2
[0070] Please refer to figure 2 , figure 2 It is a schematic structural diagram of the substrate according to Embodiment 2 of the present invention, and the substrate includes: a base substrate 101 and four edge-grinding detection patterns 102 arranged on the base substrate 101, and the four edge-grinding detection patterns 102 are respectively Set on the four edges of the base substrate 101, the edge grinding detection pattern 102 is made of conductive material.
[0071] In the embodiment of the present invention, each of the edge grinding detection patterns 102 includes a plurality of resistance blocks 203 and a plurality of connecting wires 204 for connecting the plurality of resistance blocks 203 in series.
[0072] Preferably, the multiple resistor blocks 203 have the same size, and the multiple resistor blocks 203 are aligned along the extending direction of the edge of the base substrate 101 where they are located.
[0073] After the substrate of the embodiment of t...
Embodiment 3
[0080] Please refer to image 3 , image 3 It is a schematic structural diagram of the substrate according to Embodiment 3 of the present invention, and the substrate includes: a base substrate 101 and four edge-grinding detection patterns 102 arranged on the base substrate 101, and the four edge-grinding detection patterns 102 are respectively Set on the four edges of the base substrate 101, the edge grinding detection pattern 102 is made of conductive material. In the embodiment of the present invention, the edge grinding detection pattern 102 is a strip-shaped conductive pattern, and the extending direction of the long side of the strip-shaped conductive pattern is the same as the extending direction of the edge of the substrate on which it is located.
[0081] After the substrate of the embodiment of the present invention is edged, since the edge grinding detection pattern 102 is close to the edge of the substrate, each strip-shaped edge grinding detection pattern 102 may...
