The gate driver according to the present disclosure comprises multiple groups of driving units, each group of driving units comprising N driving units each of which comprises a shift register and a logic circuit, wherein N is an integer larger than 1, and an output of a shift register is connected to a logic circuit in each driving unit. The shift registers multiplex multiple clock signals with different timings. Each of the shift registers outputs an output signal to a corresponding logic circuit. A part of a clock signal is selected by the logic circuit for output. In this way, a function of outputting a multi-pulse waveform by the gate driver is achieved, which prepares for a shift register having a function of threshold voltage compensation, to make a shift register capable of multi-row scanning become feasible on a display panel.
