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.
