Abstract
The present invention provides a liquid crystal display panel of column inversion driving mode and a driving method thereof. With adding the charge control thin film transistor (T) in the pixel driving circuit and according to the positive, negative voltages provided by the data line, the high, low voltage levels and pulse widths of the clock signal (CK) provided to the gate of the charge control thin film transistor (T) are adjusted to control the times of respectively charging the pixels of two adjacent column with the positive, negative voltages, which can balance the charge effects of the pixels of two adjacent column with the positive, negative voltages to compensate the charge difference to the pixels of two adjacent columns caused by the positive, negative voltages for making the frame display effect uniform.
