Patent ID: 8525541

Claim:
A test method of a liquid crystal display panel, wherein the liquid crystal display panel comprises a plurality of pixels and a testing pad, and the pixels are disposed at intersections between a first data line, a second data line, and a third data line and a plurality of scan lines, the test method comprising: driving the scan lines to connect liquid crystal capacitors of the pixels to the first data line, the second data line, and the third data line; respectively supplying a first test voltage and a second test voltage to the first data line and the second data line, wherein the first test voltage is not equal to the second test voltage; floating the first data line; and measuring the floated first data line through the testing pad to obtain a measurement voltage and comparing the measurement voltage with the first test voltage to determine whether the liquid crystal capacitors of the pixels electrically connected to the first data line and the second data line are electrically connected with each other.
