Abstract
The present disclosure provides a GOA unit circuit, a method for driving the same, and a GOA circuit. The GOA unit circuit comprises a first input sub-circuit, a pull-up sub-circuit, a first pull-down sub-circuit, a reset sub-circuit, a second input sub-circuit, a noise control sub-circuit, a first de-noising sub-circuit, and a second de-noising sub-circuit. The first pull-down sub-circuit is connected to an output signal terminal, a first clock control signal terminal and a discharge signal terminal, a discharge signal provided by the discharge signal terminal is at a high level higher than that of an input signal provided by the input signal terminal, and the first pull-down sub-circuit is configured to discharge the output signal terminal under the control of the first clock control signal and the discharge signal, to pull down a potential at the output signal terminal to a low level. The GOA unit circuit is configured to drive gate lines of a display apparatus.
