Abstract
A drive circuit of liquid crystal panel includes a gate driver, a source driver, gate lines, and the data lines. The gate lines and the data lines define multiple pixel units each of which includes a thin-film transistor, a common electrode, a pixel electrode, and a storage capacitor. The thin-film transistor is electrically connected to the gate driver and the source driver via the gate line and the data line. The gate driver includes a drive combination circuit, which includes a first electrical switch, an amplifier, a first drive source, a second drive source, a first resistor, a third drive source, a second resistor, a third resistor, a second electrical switch and a fourth drive source. The drive circuit reduces the influence of a parasitic capacitor on the extension of conduction time of the thin-film transistor and improves the quality of a large-sized liquid crystal display device using the circuit.
