1. A generating method of a post spacer array pattern of a display panel, wherein the post spacer array pattern comprises a plurality of types of post spacers, and the generating method comprises:
obtaining a drawing layer data, a ratio data, and a positioning mode data of each of the types of the post spacers determined by a user; and
generating the post spacer array pattern according to the drawing layer data, the ratio data, the positioning mode data, and a preset design rule of each of the types of the post spacers,
wherein the post spacer array pattern comprises a plurality of post spacers, the plurality of post spacers forms a plurality of smallest repeating units, the post spacers in different ones of the smallest repeating units have a same category, same number, and a same arrangement, and the plurality of post spacers are positioned in subpixels of the display panel in a one-to-one correspondence;
wherein in any one of the types of the post spacers, the preset design rule of the one of the types of the post spacers comprises any one or more of:
a relationship between the ratio data of the one of the types of the post spacers, an area of all the types of the post spacers in a subpixel of the display panel, an area of the subpixel, and a number of the subpixels in a smallest repeating unit;
a size range of the one of the types of the post spacers;
a position relationship between the one of the types of the post spacers and other structures of the display panel; and
the plurality of types of post spacers comprise main post spacers and sub post spacers arranged in an array pattern,
in a first direction of the post spacer array pattern, a periodic length of the main post spacers is six times greater than a periodic length of the sub post spacers, and
in a second direction of the post spacer array pattern perpendicular to the first direction, a periodic length of the main post spacers is three times greater than a periodic length of the sub post spacers.
