    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.
