A driving method and a driving device (100) for a display device (200). The display device (200) comprises a pixel array consisting of several rows of sub-pixels, and each row of sub-pixels is correspondingly connected to a scan line. The driving method comprises: partitioning each row of sub-pixels into different areas, and taking the areas of the each row of sub-pixels as the charging start point positions of the scan line corresponding to the each row of sub-pixels (S101); and inputting scanning voltage signals to the different areas of a row of sub-pixels corresponding to each scan line through the charging start point positions of the each scan line to perform partition scanning for the each row of sub-pixels (S102).
