摘要： A gate drive circuit and a display panel are provided. The gate drive circuit controls, by adding a control module, the potential at a key node of an output module in a touch-control phase, that is, outputting a low-level signal of a signal switching end to a first node of the output module of the current-stage shift register in the touch-control phase, so as to stabilise the potential of the key node, i.e. the first node in the touch-control phase, thereby avoiding the case where the potential at the key node is in a floating state and thus is capacitively coupled and deviates from a stable potential; and a transition to a display stage before the touch-control state ends is made, and a high-level signal of the signal switching end is output to the first node, so as to pull up the potential at the first node.

摘要： The present invention discloses a touch display driving method, a driving module and a display device. The method includes: detecting whether a touch action occurs; performing display driving and touch driving in a first driving mode when no touch action is detected; performing display driving and touch driving in a second driving mode when a touch action is detected, wherein a touch driving frequency under the first driving mode is smaller than a touch driving frequency under the second driving mode. In the present invention, driving is performed in the first driving mode when no touch action is detected, and driving is performed in the second driving mode when a touch action is detected. A touch driving frequency under the first driving mode is smaller than a touch driving frequency under the second driving mode, which decreases driving frequency as a whole, thereby reducing power consumption of a driving module.
