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.

Abstract: The present disclosure relates to a signal selector and a driving method therefor, a display panel, and a display device. The signal selector loads a writing signal into a control end of a switching circuit during a data writing time period, and the switching circuit is connected in response to the writing signal loaded on the control end of the switching circuit, so that the writing signal is loaded to a far end of an output signal line. During a pull up period after the data writing period, a boost control signal is loaded to the control end of a boost circuit, and the boost circuit pulls up the voltage of an output end of the switching circuit in response to the boost control signal loaded on a second end of the boost circuit.
