Test method of liquid crystal display panel

A test method of a liquid crystal display panel, wherein the liquid crystal display panel comprises a plurality of pixels and a plurality of testing pads, each of the pixels comprises a precharged capacitor, a buffer, and a liquid crystal capacitor, the pixels are electrically connected to a scan line, a display line, and a plurality of data lines, and the test method comprises:

• disabling the buffer of each of the pixels;
• driving the scan line and the display line to connect the liquid crystal capacitors and the precharged capacitors of the pixels to the data lines;
• transmitting a first test voltage to odd data lines among the data lines, and transmitting a second test voltage to even data lines among the data lines, wherein the second test voltage is not equal to the first test voltage;
• floating the odd data lines or the even data lines;
• and
• measuring the floated odd data lines or even data lines through a part of the testing pads to determine whether the liquid crystal capacitors of the pixels are electrically connected with each other.

A test method of a liquid crystal display panel, wherein the liquid crystal display panel comprises M pixels and a testing pad, each of the pixels comprises a precharged capacitor, a buffer, and a liquid crystal capacitor, and the pixels are electrically connected to M scan lines, M display lines, and a data line, wherein M is an integer greater than or equal to 2, the test method comprising:

• disabling the buffer of each of the pixels;
• charging the liquid crystal capacitor and the precharged capacitor of the jth pixel to a first test voltage, wherein j is a positive integer smaller than M;
• charging the liquid crystal capacitor and the precharged capacitor of the (j+1)th pixel to a second test voltage, wherein the first test voltage is not equal to the second test voltage;
• while the (j+1)th scan line and the (j+1)th display line are driven, enabling the buffer of the jth pixel, and floating the data line;
• and
• while the (j+1)th scan line and the (j+1)th display line are driven, measuring the floated data line through the testing pad to determine whether the liquid crystal capacitors of the jth pixel and the (j+1)th pixel are electrically connected with each other.
