Claim 5:
6. The display panel driving method according to claim 4, wherein after the determining, as a target gradient pixel unit, a pixel unit with a target grayscale value less than a preset high grayscale threshold in the m gradient pixel units, and determining, as the target pixel unit row, a pixel unit row where the target gradient pixel unit is located, the display panel driving method further comprises:
determining a correction voltage corresponding to each target pixel unit row based on a preset correction voltage mapping table and a target grayscale value of each target gradient pixel unit in each target pixel unit row, wherein a mapping relationship between a plurality of target grayscale values and a plurality of correction voltages is recorded in the preset correction voltage mapping table; and
the outputting, through scanning lines corresponding to the target pixel unit row, scanning signals with turn-on voltages higher than the first turn-on voltage comprises:
outputting, through a scanning line corresponding to each target pixel unit row, a scanning signal with a turn-on voltage equal to a correction voltage corresponding to the target pixel unit row.
