1. A display driving method, comprising:
scanning a plurality of sub-pixels arranged in an N×M array one row by one row or multiple rows by multiple rows, so as to turn on each row of sub-pixels that are scanned, such that two adjacent rows of sub-pixels are simultaneously in an on-state for a duration greater than or equal to twice a unit scanning time, the unit scanning time is a time required to scan one row of sub-pixels, wherein N and M are both integers greater than 1; and
applying data signals to at least two rows of sub-pixels that are simultaneously in the on-state, such that at least a portion of rows of sub-pixels are applied with data signals for a duration greater than the unit scanning time,
wherein a duration of each row of sub-pixels other than the first row of sub-pixels are applied with data signals is greater than the unit scanning time,
wherein, in each frame, a duration for applying a gate driving signal on each row of pixels is shorter than a duration for not applying the gate driving signal on the each row of pixels, wherein,
during a first time period, a n-th row of sub-pixels and a (n+1)-th row of sub-pixels are simultaneously turned on, where n is an integer, and 1En≤N−1;
during a second time period, a (n+2)-th row of sub-pixels and a (n+3)-th row of sub-pixels are simultaneously turned on, and data signals are applied to the n-th row of sub-pixels and the (n+1)-th row of sub-pixels, and a length of the second time period is greater than or equal to twice the unit scanning time,
wherein lengths of the first time period and the second time period are both equal to twice the unit scanning time.
