The present disclosure relates to the field of display technology, and proposes a gate driving circuit and a driving method thereof, and a display panel. The gate driving circuit includes a plurality of cascaded shift register units and switch unit groups. Each of the shift register units and at least one row of pixel units are correspondingly arranged; and switch unit group are arranged between at least a part of adjacent two shift register units. The switch unit group includes a first switch unit and a second switch unit. The first switch unit is used to turn on the output terminal of the shift register unit of the previous stage and the input terminal of the shift register unit of the adjacent next stage in response to a control signal; and the second switch unit is used to turn on the output terminal of the shift register unit of the previous stage and the output terminal of the shift register unit of the adjacent next stage in response to a control signal, wherein the first switch unit and the second switch unit are turned on selectively during a driving period.
