Abstract: A display apparatus includes sub-pixels, at least one gate line group and a scan drive circuit. The gate line group includes a first gate line, a second gate line and a third gate line. The scan drive circuit outputs, in a frame scan cycle, a first scan signal to the first gate line, a second scan signal to the second gate line, and a third scan signal to the third gate line in sequence. Durations of effective scan periods of the scan signals are equal. A start moment of the effective scan period of the second scan signal is delayed by a first time length compared with that of the first scan signal. A start moment of the effective scan period of the third scan signal is delayed by a second time length less than the first time length compared with that of the second scan signal.
