Abstract: 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.

Abstract: A method for driving display panel and a driving device are disclosed. A transition period is inserted between displaying two neighboring frames, pixels in the nth row to the Nth row of the display panel are switched on simultaneously in the transition period, and a voltage with the highest grayscale is applied to the pixels which are switched on. This is equivalent to turning the grayscale of pixels in the nth row to the Nth row into the highest grayscale after displaying a frame and before displaying a next frame. This can improve the response time of pixels in the nth row to the Nth row during displaying the next frame, and thus can increase the display quality of the display panel.
