Claim 9:
10. 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 digital exposure machine comprises:
a processor, configured to:
determine 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;
determine 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 perform a plurality of scannings to expose a display region of the first display substrate to be exposed; and
control a scanning module to perform the plurality of scannings with a start at the starting scanning position in the scanning direction of the digital exposure machine, to expose the display region of the first display substrate to be exposed, and
the scanning module, configured to perform the plurality of scannings,
wherein a scanning pitch used in each of the plurality of scannings is integer times of a pitch of two adjacent rows of sub-pixels of the first display substrate to be exposed in the scanning direction.
