A display driving method and a display device are provided. The display driving method includes: scanning a plurality of subpixels arranged in an NΔM array row by row or in multiple rows to turn on each row of scanned subpixels, so that the duration when two adjacent rows of subpixels are simultaneously in a turn-on state is greater than or equal to two times a unit scan time, the unit scan time being the time required for scanning one row of subpixels, and N and M both being integers greater than 1; and applying data signals to at least two rows of subpixels that are simultaneously in the turn-on state, so that the duration when data signals are applied to at least some rows of subpixels is greater than the unit scan time.
