发明名称 Gate driver circuit
摘要 A gate driver circuit includes several shift register stages. One of shifter register stages includes a pull-up unit, a pull-up control unit, and an output unit. The pull-up unit is configured for generating a driving signal according to a first clock signal and an operating signal. The pull-up control unit is configured for generating a next-stage operating signal to a next-stage shift register stage according to the first clock signal, the operating signal and the driving signal. The output unit is configured for receiving the driving signal and generating a first gate driving signal and a second gate driving signal according to a first controlling signal and a second controlling signal, respectively.

主权项 1. A gate driver circuit comprising a plurality of series-coupled shift register stages, an n-th shift register stage of the shift register stages comprising: a pull-up unit configured for receiving a clock signal and an n-th operating signal, wherein when the n-th operating signal is at high logic level, the pull-up unit generates an n-th driving signal according to the clock signal; a pull-up control unit configured for receiving the clock signal, the n-th operating signal, and the n-th driving signal, wherein when the n-th operating signal is at high logic level, the pull-up control unit outputs the n-th driving signal to an (n+1)-th shift register stage according to the clock signal; and an output unit configured for receiving the n-th driving signal, generating a first gate driving signal according to a first controlling signal, and generating a second gate driving signal according to a second controlling signal, wherein the first controlling signal and the second controlling signal are non-overlapped, wherein n is a positive integer.
