US Patent 7898558 Gate driving circuit and driving circuit unit thereof

A driving circuit unit outputting a driving signal includes an input unit, an assistant output unit and an output unit. The input unit is coupled to an input node and receives a start signal to make the input node have a potential. The assistant output unit receives a first clock signal to increase the potential of the input node. The output unit receives a second clock signal to increase the potential of the input node and outputs the driving signal. A gate driving circuit is also disclosed.
