  • Driving method, gate drive unit and display touch device
    Patent number: 11733806
    Abstract: Provided are a driving method, a gate drive unit and a display touch device. The driving method is applied to the gate drive unit in the display touch device. The gate drive unit includes at least one pull-down circuit. The 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 includes 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. The driving method includes: 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. The problem of a screen flashing phenomenon of existing display touch devices during the touch phase is solved.
