Abstract
A LCD panel driving circuit for controlling a LCD panel, the LCD panel comprising display units respectively connected to corresponding data and gate electrodes. The LCD panel driving circuit comprises a data driver, a first gate driver, and a second gate driver. The data driver outputs a video signal to the data electrodes, and determines the video signal polarity according to a polar control signal. The first gate driver is coupled to a first terminal of each gate electrode for output of a pulse signal to the corresponding gate electrodes. The second gate driver is coupled to a second terminal of each gate electrode for output of the pulse signal to the corresponding gate electrodes. The first gate driver and second gate driver determine whether the pulse signal is output according to an external clock signal and an internally shifted signal.
