Abstract:
1. A gate switch apparatus of an LCD, comprising: at least one input end, receiving at least one a gate signal provided by a gate line; a plurality of output ends, respectively coupled to a plurality of sub-gate lines, and each of the sub-gate lines provides a sub-gate line signal; and a gate switch circuit, coupled between the output ends and the input ends, controlled by a plurality of switch signals, outputting the gate signal from the input end to one of the output ends as the corresponding sub-gate line signal according to the switch signals, wherein the switch signals are time-division conductive signals, and when only one of the switch signals is turned on, all other switch signals are turned off, and the turning on sequence of each switch signal is such that only after the corresponded gate signal takes a turning-on voltage level, the one of the switch signals takes a turning-on voltage level; only after the corresponded gate signal takes a turning-off voltage level, the one of the switch signals takes a turning-off voltage level, and the produced sub-gate line signal is an intersection of the corresponded gate signal and the switch signal in terms of time domain.
