Title: SHIFT REGISTER, GATE DRIVE CIRCUIT, DISPLAY PANEL, AND DRIVE METHOD
Abstract:
Disclosed are a shift register, a gate drive circuit, a display panel and a drive method. The shift register (100) comprises: an input and reset circuit (100), connected to a pull-up node (PU), and a drive circuit (200) connected to the pull-up node (PU), wherein the input and reset circuit (100) is configured for: during an input state of a forward scan, in response to a second signal (S2), writing a voltage of a first signal (S1) into the pull-up node (PU); during a reset state of a forward scan, in response to a third signal (S3), writing a voltage of a fourth signal (S4) into the pull-up node (PU); during an input state of a reverse scan, in response to the third signal (S3), writing a voltage of the fourth signal (S4) into the pull-up node (PU); and during a reset state of a reverse scan, in response to a second signal (S2), writing a voltage of the first signal (S1) into the pull-up node (PU). The shift register, the gate drive circuit, the display panel and the drive method can realize a bidirectional scan of the gate drive circuit and improve the compatibility of a display panel.
