Patent ID: 8184086

Claim:
An LCD device, comprising: a plurality of gate lines formed in an LCD panel; a plurality of driving stages, each of which sequentially outputting a respective enabling scan pulse to a corresponding one of the plurality of gate lines; and at least one dummy stage responsive to an enabling scan pulse from a first one of the plurality of driving stages and supplying a disabling scan pulse to a second one of the plurality of driving stages to disable outputting of the enabling scan pulse; and an RC load electrically connected to the at least one dummy stage; wherein each of the driving stage includes a first switching device for charging a first node with a high-potential voltage source in response to a start pulse or a enabling scan pulse of the preceding driving stage; a second switching device for discharging a second node with a low-potential voltage source in response to the start pulse or the enabling scan pulse of the preceding driving stage; a third switching device for charging the second node with the high-potential voltage source in response to a first clock pulse synchronized with the enabling scan pulse outputted from a following driving stage; a fourth switching device for discharging the first node with the low-potential voltage source in response to the high-potential voltage source charged in the second node; a fifth switching device for discharging the second node with the low-potential voltage source in response to the high-potential voltage source charged in the first node; a sixth switching device for discharging the first node with the low-potential voltage source in response to the enabling scan pulse outputted from the following driving stage; a pull-up switching device for outputting a second clock pulse prior to the first clock pulse as the enabling scan pulse in response to the high-potential voltage source charged in the first node; and a pull-down switching device for outputting the low-potential voltage source in response to the high-potential voltage source charged in the second node.
