1. A driving method for a display panel, the display panel comprises a plurality of data line groups and a plurality of multiplexers in one-to-one correspondence with the data line groups, each of the data line groups comprises at least three data lines, and each of the multiplexers is configured to enable an input terminal of said each of the multiplexers to be successively coupled to the data lines electrically in the data line group, corresponding to said each of the multiplexers, in each line scanning period, and for at least one of the data line groups, the driving method comprises:
acquiring data voltages to be output to the data lines in the data line group in a current line scanning period;
in response to that the data voltages to be output to the data lines in the data line group are not completely equal to each other, successively outputting the data voltages to be output to the data lines to the input terminal of the multiplexer corresponding to the data line group in a sequence from large to small or from small to large, and controlling the multiplexer to electrically couple the input terminal of the multiplexer to the data line to receive the data voltage in response to that each of the data voltages is output to the input terminal of the multiplexer.
