1. A signal selector, configured to distribute a signal on an input data line to different output data lines, wherein each output data line is configured to drive a sub-pixel of a display panel, and wherein:
the signal selector comprises a plurality of switch units, and any switch unit comprises:
a switch circuit, coupled to the input data line and an output data line, and configured to conduct in response to a write signal loaded on a control terminal of the switch circuit; and
a boost circuit, wherein a first terminal of the boost circuit is electrically coupled to an output terminal of the switch circuit, and the boost circuit is configured to pull up a voltage of the output terminal of the switch circuit in response to a boost control signal loaded on a control terminal of the boost circuit,
wherein the boost circuit comprises a boost capacitor, and an electrode plate of the boost capacitor is used as the first terminal of the boost circuit to be electrically coupled to the output terminal of the switch circuit; and
the other electrode plate of the boost capacitor is used as the control terminal of the boost circuit to load the boost control signal.
