Method of driving display, and display device

A method of driving display, comprising:

• in a first frame, scanning progressively or at an interval of at least one row, a plurality of sub-pixels arranged in an N×M array by using gate driving signals, to turn on each row of sub-pixels scanned, so that a duration in which two rows of sub-pixels turned on sequentially are simultaneously in an ON state is greater than or equal to two times a unit scanning time;
• and applying data signals to each row of sub-pixels turned on, so that a duration of applying the data signals to a part of the plurality of sub-pixels is greater than the unit scanning time, wherein the unit scanning time is a time required for scanning a row of sub-pixels, N is an integer greater than 1, and M is an integer greater than 1;
• and
• in a second frame, scanning progressively or at an interval of at least one row, a plurality of sub-pixels arranged in an N×M array by using gate driving signals, to turn on each row of sub-pixels scanned, so that a duration in which two rows of sub-pixels turned on sequentially are simultaneously in an ON state is greater than or equal to two times the unit scanning time;
• and applying data signals to each row of sub-pixels turned on, so that a duration of applying the data signals to the other part of the plurality of sub-pixels is greater than the unit scanning time,
• wherein a duration of an effective level of the gate driving signals is smaller than a duration of a non-effective level of the gate driving signals.
