1. A display panel, comprising:
a pre-charge circuit, a data-signal line and a pixel circuit, wherein:
the pre-charge circuit is electrically connected to the pixel circuit through the data-signal line;
before a data signal is written into the pixel circuit, the pre-charge circuit provides a pre-charge voltage signal to the data-signal line, and the data-signal line is charged through the pre-charge voltage signal; and
the pre-charge circuit includes a pre-charge unit, wherein a control terminal of the pre-charge unit is electrically connected to a first control signal line, a first terminal of the pre-charge unit is electrically connected to a pre-charge voltage signal terminal, and the second terminal of the pre-charge unit is electrically connected to the data-signal line; and the pre-charge unit is configured to be in conduction under control of the first control signal line and transmit a pre-charge voltage signal of the pre-charge voltage signal terminal to the data-signal line.
