1. A driving method, applied to a gate drive unit in a display touch device, wherein the gate drive unit comprises at least one pull-down circuit; the at least one pull-down circuit is coupled with a pull-up node and a pull-down voltage terminal, and is configured to control connection or disconnection between the pull-up node and the pull-down voltage terminal; one frame of image display time comprises a display phase and a touch phase that are alternately set, and at least one of the touch phase is set between two adjacent display phases;
and the driving method comprises: during the touch phase, controlling, by the at least one pull-down circuit, the disconnection between the pull-up node and the pull-down voltage terminal,
wherein the at least one pull-down circuit is configured to control a duration of the disconnection between the pull-up node and the pull-down voltage terminal to be greater than or equal to a duration of the touch phase.
