Display panel and drive method thereof, and display device

A display panel, comprising:

• a plurality of first-color sub-pixels, wherein:
• a first-color picture is configured to be refreshed N times in one frame, wherein a time interval between every two adjacent refreshings of the N times of the refreshings is T1 for the first-color picture, T1=T2/N, T2 is a duration of the one frame, N >1, and N is a positive integer;
• the display panel includes a plurality of first-color sub-pixels arranged in n rows, and the plurality of first-color sub-pixels is configured to display the first-color picture;
• and
• refreshing the first-color picture N times includes:
• at step 1, sequentially scanning the plurality of first-color sub-pixels from a first row to an i-th row till i=n, wherein 1≤i≤n, and i is a positive integer;
• and
• at step 2, repeating step 1 for N−1 times.
