Patent ID: 7626568

Claim:
A gate switch apparatus of a LCD, suitable for a gate line to switch a plurality of sub gate lines, the gate switch apparatus comprising: a plurality of first switches, wherein each of the first switches comprises a first end and a second end for receiving a switch signal, the first end of each first switch is coupled to the gate line, the second end of each first switch is coupled one-on-one to the corresponding sub gate lines, and the switch signals turn on or off the electric connection between the first end and the second end; and a plurality of second switches, wherein each of the second switches comprises a third end and a fourth end for receiving an inverting switch signal, the third end of each second switch is coupled one-on-one to the corresponding second end of the first switch, the fourth end of each second switch is coupled to a first voltage level, and the inverting switch signal turns on or off the electric connection between the third end and the fourth end; wherein the gate line provides a gate signal, and a period that the gate signal is driven is longer than a summation of periods that the switch signals are asserted, and the first switches are conducted when the switch signals are asserted and the gate signal is driven.
