Disclosed are a gate driving apparatus (200) for a pixel array and a driving method therefor. The pixel array comprises N gate lines. The gate driving apparatus (200) comprises: a plurality of gate drivers (221, 222,..., 22(n-1), 22n), wherein the N gate lines are divided into a plurality of groups, each group comprises a plurality of gate lines, each gate driver (221, 222,..., 22(n-1), 22n) corresponds to the plurality of groups on a one-to-one basis, and each gate driver (221, 222,..., 22(n-1), 22n) is used for generating a gate driving signal for the plurality of gate lines in the group corresponding thereto; and a driver control module (210) which is used for generating a plurality of driver control signals (XON1, XON2,..., XON(n-1), XONn), the plurality of driver control signals (XON1, XON2,..., XON(n-1), XONn) corresponding to the plurality of gate drivers (221, 222,..., 22(n-1), 22n) on a one-to-one basis, and a state switch between any two driver control signals among the plurality of driver control signals (XON1, XON2,..., XON(n-1), XONn) has at least a difference of a first time, wherein under the control of the plurality of driver control signals (XON1, XON2,..., XON(n-1), XONn), the plurality of gate drivers (221, 222,..., 22(n-1), 22n) are switched from a first state to a second state in sequence, and each gate driver (221, 222,..., 22(n-1), 22n) generates gate driving signals in the same phase at the same time for the plurality of gate lines in the group corresponding thereto in the second state.
