Abstract
Provided are a shift register and a driving method thereof, a gate on array circuit and a display apparatus. The shift register includes a pre-charging module, an output module, a reset module and a reset control module. The pre-charging module is configured to charge a first node in a pre-charging period. The output module is configured to pull up a voltage at the first node and output a driving signal through the output signal terminal in an output period. The reset control module is configured to pull up a voltage at the second node by the driving signal outputted through the output signal terminal in the output period and output the voltage at the second node pulled up in the output period to the reset module as a reset signal in a reset period.
Claims19
A shift register, comprising a pre-charging module, an output module, a reset module and a reset control module, the pre-charging module being connected to a first node, the output module being connected to the first node and an output signal terminal, the reset module being connected to a second node, the first node and the output signal terminal, and the reset control module being connected to the second node and the output signal terminal, wherein
- the pre-charging module is configured to charge the first node in a pre-charging period;
- the output module is configured to pull up a voltage at the first node and output a driving signal through the output signal terminal in an output period;
- the reset control module is configured to pull up a voltage at the second node by the driving signal outputted through the output signal terminal in the output period and output the voltage at the second node pulled up in the output period to the reset module as a reset signal in a reset period;
- and
- the reset module is configured to reset the first node and the output signal terminal under control of the reset signal in the reset period.
A driving method of a shift register, wherein the shift register comprises a pre-charging module, an output module, a reset module and a reset control module, the pre-charging module being connected to a first node, the output module being connected to the first node and an output signal terminal, the reset module being connected to a second node, the first node and the output signal terminal, and the reset control module being connected to a second node and the output signal terminal;
- the driving method comprises:
- in a pre-charging period, charging the first node by the pre-charging module;
- in an output period, pulling up a voltage at the first node and outputting a driving signal through the output signal terminal by the output module, and pulling up a voltage at the second node by the reset control module through the driving signal outputted through the output signal terminal;
- and
- in a reset period, outputting, by the reset control module, the voltage at the second node pulled up in the output period to the reset module as a reset signal, and resetting the first node and the output signal terminal by the reset module under control of the reset signal.
