Abstract: The embodiments of the present disclosure disclose a gate driving circuit and a display panel. In the gate driving circuit, a control unit of a shift register may input a dual pulse control signal to a first control terminal of an output unit; and the output unit outputs a scanning signal having a pulse width equal to a pulse period of the dual pulse control signal to a corresponding gate line under the control of the dual pulse control signal. In this way, the output unit is controlled by the control unit to output a scanning signal of which a pulse width may be modulated, so as to output a gate signal of which a pulse width may be modulated.
