Abstract
Disclosed are a gate driving apparatus for a pixel array and a driving method therefor. The pixel array includes N gate lines. The gate driving apparatus includes: a plurality of gate drivers, wherein the N gate lines are divided into a plurality of groups, each group includes a plurality of gate lines, each gate driver corresponds to the plurality of groups on a one-to-one basis, and is used for generating a gate driving signal for the plurality of gate lines in the group corresponding thereto; and a driver control module which is used for generating a plurality of driver control signals corresponding to the plurality of gate drivers on a one-to-one basis, and state switching between any two driver control signals has at least a difference of first time, wherein under control of the driver control signals, the gate drivers are switched from first state to second state in sequence.
