A gate driving unit includes an input circuit, a pull-up circuit, a reset circuit, and an output circuit. The pull-up driving signals received by the input circuit include the gate driving signals for pixel units of row n−2 and row n+4. The reset driving signals received by the reset circuit include the gate driving signals for pixel units of row n+2 and row n+8. The gate driving signals output from the output circuit include the gate driving signals for pixel units of row n and row n+6. Where, n is a positive integer and nε[3,∞). The gate driving unit can output gate driving signals of two rows of pixel units and thus has a high service efficiency. An area occupied by a gate driving circuit made of the gate driving units is reduced, and a driving efficiency of the gate driving circuit is increased.
