Abstract
The present invention provides a drive circuit of liquid crystal panel, which includes a gate driver, a source driver, a plurality of gate lines, and a plurality of data lines. The plurality of gate lines and data lines define a plurality of pixel units. Each of the pixel units includes a thin-film transistor, a common electrode, a pixel electrode electrically connected to the thin-film transistor, and a correction capacitor. The thin-film transistor is electrically connected to the gate driver and the source driver respectively by means of the gate lines and the data lines. The common electrode and the pixel electrode constitute a liquid crystal capacitor. The thin-film transistor includes a gate terminal and a drain terminal. The correction capacitor is electrically connected between the gate terminal and the drain terminal for correcting a parasitic capacitor generated between the gate terminal ad the drain terminal due to structural characteristics.
