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： A stylus pen that includes a tip electrode, a power supply circuit, a signal detector, and a drive circuit where an output signal is transmitted to and an input signal is received from a touch panel via the tip electrode. The power supply circuit of the stylus pen selectively supplies a first supply voltage or a second supply voltage. The signal detector of the stylus pen detects an enable signal from the input signal and the signal detector of the stylus pen controls the power supply circuit to supply the first supply voltage in response to presence of the enable signal. The drive circuit operates at the first supply voltage to generate the output signal.
