Driving method of display panel and display device

The embodiment of the invention discloses a driving method of a display panel and a display device. The driving method of the display panel comprises the steps of obtaining display data of a current display frame; inputting a data voltage to the data line according to the display data, so that the sub-pixels electrically connected with the data line are charged with the corresponding data voltage; wherein the data voltages on the input data line are divided into a plurality of voltage groups, each voltage group comprises at least two adjacent data voltages, and the polarities corresponding to the data voltages in the same voltage group are the same; the polarities corresponding to the data voltages in the two adjacent voltage groups input into the same data line are different; and the polarities of the corresponding voltage groups on the two adjacent data lines are different. 本公开实施例公开了显示面板的驱动方法及显示装置，显示面板的驱动方法包括：获取当前显示帧的显示数据；根据显示数据，对数据线输入数据电压，以使数据线电连接的子像素充入对应的数据电压；其中，将输入数据线上的数据电压分为多个电压组，每个电压组包括相邻的至少两个数据电压，同一电压
