1. A display apparatus, comprising:
a plurality of sub-pixels, arranged in an array;
at least one gate line group, wherein the gate line group includes multiple gate lines, and the multiple gate lines include a first gate line, a second gate line and a third gate line that are arranged sequentially along a column direction of the array; and
a scan drive circuit, wherein the scan drive circuit is coupled to the multiple gate lines in the gate line group, and is configured to, in a frame scan cycle, respectively output scan signals to the multiple gate lines in the gate line group, which includes: outputting a first scan signal to the first gate line, outputting a second scan signal to the second gate line, and outputting a third scan signal to the third gate line in sequence;
wherein a duration of an effective scan period of the first scan signal, a duration of an effective scan period of the second scan signal, and a duration of an effective scan period of the third scan signal are equal; and a start moment of the effective scan period of the second scan signal is delayed by a first time length compared with a start moment of the effective scan period of the first scan signal, and a start moment of the effective scan period of the third scan signal is delayed by a second time length compared with the start moment of the effective scan period of the second scan signal; and
the second time length is less than the first time length; wherein
for scan signals respectively output by the scan drive circuit to any two adjacent gate lines in the gate line group, respective effective scan periods at least partially overlap with each other;
the at least one gate line group includes a first gate line group and a second gate line group that are arranged adjacent to each other along the column direction;
a start moment of an effective scan period of a first scan signal output from a first gate line in the second gate line group is delayed by a fourth time length compared with a start moment of an effective scan period of a fourth scan signal output from a fourth gate line in the first gate line group; and
the fourth time length is equal to the first time length.
