Abstract
A driving method and a driving device for a display panel and a display device are provided. The display panel includes data line groups and multiplexers, each data line group includes at least three data lines, each multiplexer successively couples the input terminal thereof to the data lines electrically in the data line group in each line scanning period; and for at least one data line group, the driving method includes: 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 are not completely equal to each other, successively outputting the data voltages to the input terminal of the multiplexer corresponding to the data line group, and controlling the multiplexer to electrically couple the input terminal thereof to the data line to receive the data voltages.
