Abstract
A gate driving circuit and a liquid crystal display are provided, wherein the gate driving circuit comprises a gate pulse modulator and a controlling circuit, the controlling circuit comprises at least one sub controlling circuit; an input terminal of each sub controlling circuit of the at least one sub controlling circuit is connected to an output terminal of the gate pulse modulator; an output terminal of each sub controlling circuit is connected to a power source; the power source outputs a level signal to each sub controlling circuit; each sub controlling circuit controls a conduction between each sub controlling circuit and the gate pulse modulator according to the level signal, so as to control the gate driving circuit to output at least one gate driving voltage. The present disclosure may generate a plurality of gate driving voltages, thereby increasing the display effect of the liquid crystal display.
