Claim 4:
5. The method of claim 2, wherein the operation of searching for points to be filled among adjacent points of the bright point of each sub-pixel in the sub-pixel mark map according to a first direction pixel pitch and a second direction pixel pitch in the original image of the sub-pixel, filling the points to be filled until the points to be filled do not exist in the original image of the sub-pixel, to obtain a filling mark map comprises:
searching for empty points among the adjacent points of the bright point of each sub-pixel in the sub-pixel mark map according to the first direction pixel pitch and the second direction pixel pitch, and screening the empty points to obtain the points to be filled, to generate a first mark map;
if a number of points to be filled is less than or equal to zero, using the first mark map as the filling mark map; if the number of points to be filled is greater than zero, filling the points to be filled in the first mark map, and using the filled point as the bright point of the sub-pixel; and
updating the filled first mark map to the sub-pixel mark map, returning to the operation of searching for the empty points among the adjacent points of the bright point of each sub-pixel in the sub-pixel mark map according to the first direction pixel pitch and the second direction pixel pitch, and screening the empty points to obtain the points to be filled, to generate the first mark map.
