1. A liquid crystal display panel, comprising:

  • a plurality of data lines extending along a first direction and a plurality of gate lines extending along a second direction, wherein a plurality of sub-pixels are defined by insulatedly intersecting the plurality of data lines with the plurality of gate lines,wherein each of the plurality of data lines is configured to provide a data signal to a corresponding sub-pixel by column, and polarities of the data signals provided by two adjacent data lines are inverse to each other, wherein, during a scanning period for a frame of image, the polarities of the data signals provided by the data lines in a former half of the scanning period for the frame of image are inverse to the polarities of the data signals provided by the data lines in a latter half of the scanning period for the frame of image;

    the plurality of gate lines comprise a group of first gate lines comprising a plurality of first gate lines, and a group of second gate lines comprising a plurality of second gate lines, wherein at least a part of the plurality of first gate lines are alternately disposed line by line with at least a part of the plurality of second gate lines;

    the liquid crystal display panel further comprises a group of first gate drivers configured to drive the group of first gate lines, and a group of second gate drivers configured to drive the group of second gate lines, wherein the group of first gate drivers drive the first gate lines in a direction inverse to a direction in which the group of second gate drivers drive the second gate lines;

    two of the plurality of first gate lines are consecutively disposed at intermediate positions in a region where all the gate lines are disposed; and

    the remaining first gate lines are alternately disposed line by line with the plurality of second gate lines at positions except for the intermediate positions;

    the two first gate lines consecutively disposed at the intermediate positions in the region where all the gate lines are disposed are respectively configured to control two adjacent rows of sub-pixels, and during the scanning period for the frame of image, the polarities of the data signals provided for one of the two adjacent rows of sub-pixels by the data lines are inversed to the polarities of the data signals provided for the other of the two adjacent rows of sub-pixels by the data lines, respectively;

    the group of first gate drivers comprises a first sub-group of gate drivers and a third sub-group of gate drivers; and

    the group of second gate drivers comprises a second sub-group of gate drivers and a fourth sub-group of gate drivers;

    the group of first gate lines comprises a group of first sub gate lines and a group of third sub gate lines, wherein the group of first sub gate lines comprises a plurality of first sub gate lines, and the group of third sub gate lines comprises a plurality of third sub gate lines;

    while the group of second gate lines comprises a group of second sub gate lines and a group of fourth sub gate lines, wherein the group of second sub gate lines comprises a plurality of second sub gate lines, and the group of fourth sub gate lines comprises a plurality of fourth sub gate lines;

    wherein the plurality of first sub gate lines are alternately disposed line by line with the plurality of fourth sub gate lines, and the plurality of second sub gate lines are alternately disposed line by line with the plurality of third sub gate lines;

    the first sub-group of gate drivers is configured to drive the group of first sub gate lines;

    the second sub-group of gate drivers is configured to drive the group of second sub gate lines;

    the third sub-group of gate drivers is configured to drive the group of third sub gate lines;

    the fourth sub-group of gate drivers is configured to drive the group of fourth sub gate lines;

    the group of first sub gate lines is disposed adjacently to the group of third sub gate lines, and one of first sub gate lines that is last driven by the first sub-group of gate drivers is consecutively disposed with one of third sub gate lines that is first driven by the third sub-group of gate drivers;

    the first sub-group of gate drivers drives the first sub gate lines in a direction same as a direction in which the third sub-group of gate drivers drives the third sub gate lines; and

    the second sub-group of gate drivers drives the second sub gate lines in a direction same as a direction in which the fourth sub-group of gate drivers drives the fourth sub gate lines; and

    during the former half of the scanning period for the frame of image, the first sub-group of gate drivers sequentially applies a high level signal to each of the plurality of first sub gate lines;

    the second sub-group of gate drivers sequentially applies the high level signal to each of the plurality of second sub gate lines; and

    both the third sub-group of gate drivers and the fourth sub-group of gate drivers output a low level signal;

    wherein the first sub-group of gate drivers drives the first sub gate lines in a direction inverse to a direction in which the second sub-group of gate drivers drives the second sub gate lines;

    during the latter half of the scanning period for the frame of image, the third sub-group of gate drivers sequentially applies the high level signal to each of the plurality of first sub gate lines;

    the fourth sub-group of gate drivers sequentially applies the high level signal to each of the plurality of second sub gate lines; and

    both the first sub-group of gate drivers and the second sub-group of gate drivers output the low level signal;

    wherein the third sub-group of gate drivers drives the third sub gate lines in a direction inverse to a direction in which the fourth sub-group of gate drivers drives the fourth sub gate lines.
