    • A shift register includes multiple cascade-connected stages. Each stage generates an output signal in response to a clock signal and a first control signal. Each stage includes a pull-up module, a pull-up driving module, a first pull-down module, a second pull-down module, and a third pull-down module. The pull-up module is used for providing the output signal based on the clock signal. The pull-up driving module turns on the pull-up module in response to a first control signal. The first pull-down module adjusts voltage level on the first node to a first supply voltage in response to a second control signal. The second pull-down module adjusts voltage level on the output end to a second supply voltage in response to the second control signal. The third pull-down module adjusts voltage level on the second node to a third supply voltage in response to a third control signal.

    • An exemplary shift register includes a plurality of transistors. The transistors are subjected to the control of a start pulse signal, a first clock signal and a second clock signal to generate a gate driving signal. The first clock signal and the second clock signal are phase-inverted with respect to each other. A logic low level of the first clock signal and another logic low level of the second clock signal are different from each other. Moreover, the transistors are negative threshold voltage transistors. A potential at the gate of the each of the transistors is lower than another potential at the source/drain of the transistor at the situation of the transistor being switched-off state.

    • A shift register is provided and includes a first shift registering unit and a second shift registering unit. The first shift registering unit generates a first trigger signal at a first output terminal and includes a first pull-down circuit. The second shift registering unit receives the first trigger signal and generates a second trigger signal at a second output terminal. The first trigger signal and the second trigger signal are sequentially asserted. The second shift registering unit includes a second pull-down circuit. The first pull-down circuit and the second pull-down circuit perform pull-down operations at different times. When the first pull-down circuit does not perform the pull-down operation, the second pull-down circuit performs pull-down operations to the first output terminal.
