1. A display panel, comprising:

  • scan lines extending in a first direction and configured to provide a scan signal;

    data lines extending in a second direction, arranged intersecting the scan line and configured to provide a data signal in a square-wave form, wherein a waveform of the data signal has a starting end where a polarity of the data signal is inverted and gradually rises to a predetermined value, and a trailing end where the data signal reaches the predetermined value;

    a sub-pixel group, connected to the scan lines and the data lines, the sub-pixel group comprising a sub sub-pixel and a positive sub-pixel, wherein when the scan signal is turned on, the sub sub-pixel is charged through the data signal at the starting end, and the positive sub-pixel is charged through the data signal at the trailing end; and

    a driving module, connected to the scan lines and the data lines and configured to control signal output of the scan lines and the data lines, wherein the driving module controls the scan line connected to the sub sub-pixel to provide the scan signal and a precharge signal prior to the scan signal, the polarity of the data signal when the precharge signal is provided by the scan line is the same as that when the scan signal is provided by the scan line, and the driving module controls the scan line connected to the positive sub-pixel to provide a scan signal.
