1. An exposure control method of a digital exposure machine applied to a display mother board to be exposed, the display mother board to be exposed comprising at least a first display substrate to be exposed, the first display substrate to be exposed comprising a plurality of sub-pixels arranged in an array, wherein the exposure control method comprises:
determining a scanning direction of the digital exposure machine, wherein the plurality of sub-pixels comprise multiple rows of sub-pixels arranged in the scanning direction, and the multiple rows of sub-pixels comprise a first row of sub-pixels in the scanning direction;
determining a starting scanning position, the starting scanning position being located on an outer side of the first row of sub-pixels in the scanning direction; and
performing a plurality of scannings to expose a display region of the first display substrate to be exposed,
wherein a scanning pitch for each of the plurality of scannings is integer times of a pitch of two adjacent rows of sub-pixels of the first display substrate in the scanning direction.
