Driving method of display panel and display device

A driving method of a display panel, wherein the display panel comprises a display array comprising sub-pixels arranged in an array;

• the driving method comprises:
• dividing scanning lines of the display array into two groups comprising a first group of scanning lines and a second group of scanning lines, connecting odd-numbered column sub-pixels in a first row and even-numbered column sub-pixels in a second row of two adjacent rows of sub-pixels with the first group of scanning lines, and connecting even-numbered column sub-pixels in the first row and odd-numbered column sub-pixels in the second row with the second group of scanning lines;
• acquiring a first preset scanning driving signal output by the first group of scanning lines and a second preset scanning driving signal output by the second group of scanning lines, the first preset scanning driving signal and the second preset scanning driving signal adopting different driving times;
• dividing a driving period for driving the two adjacent rows of sub-pixels into a first driving period and a second driving period;
• acquiring a current frame signal, a time signal or a power on/off signal, and driving the odd-numbered column sub-pixels in the first row and the even-numbered column sub-pixels in the second row of the two adjacent rows of sub-pixels by adopting the first preset scanning driving signal during the first driving period;
• acquiring a period switching signal, and switching the first driving period to the second driving period according to the period switching signal;
• and
• driving the even-numbered column sub-pixels in the first row and the odd-numbered column sub-pixels in the second row by adopting the second preset scanning driving signal.
