Abstract
A shift register, a gate driver, a display panel and a driving method are provided. The shift register includes an input-reset circuit, which is connected with a pull-up node; and a driving circuit, which is connected with the pull-up node. The input-reset circuit is configured to: write a voltage of a first signal into the pull-up node in response to a second signal, in an input phase of forward scanning; write a voltage of a fourth signal into the pull-up node in response to a third signal, in a reset phase of forward scanning; write the voltage of the fourth signal into the pull-up node in response to the third signal, in an input phase of reverse scanning; and write the voltage of the first signal into the pull-up node in response to the second signal, in a reset phase of reverse scanning.
