Claim 16:
17. A detection method for a liquid crystal display panel, comprising:
connecting a detection device to a detection pad in the liquid crystal display panel, wherein the liquid crystal display panel, comprising:
a color filter substrate provided with a common electrode layer thereon; and
an array substrate arranged in cell alignment with the color filter substrate, and provided with a common electrode line thereon, wherein the array substrate comprises a display area and a peripheral area, the peripheral area comprising a plurality of connection areas; and a plurality of conductive members located on the connection areas and arranged between the color filter substrate and the array substrate;
wherein at least one connection area comprises a conductive sub-region and a detection sub-region, and the conductive members located on the conductive sub-region are respectively in contact with the common electrode line and the common electrode layer, and configured for conducting the common electrode line and the common electrode layer; and
the conductive members located on the detection sub-region are respectively in contact with the common electrode layer and the detection pad, and configured for conducting the common electrode layer and the detection pad; the detection pad is arranged on the array substrate and the detection pad is not in contact with the common electrode line; and
determining whether a voltage is detected on the detection pad through the detection device;
wherein when the voltage is detected from the detection device, the common electrode layer on the color filter substrate and the common electrode line on the array substrate are in normal conduction; and
when no voltage is detected from the detection device, the common electrode layer on the color filter substrate and the common electrode line on the array substrate are not conducted.
