1. A pixel arrangement structure comprising:
a plurality of repeat units arranged in an array, each of the repeat units being a quadrilateral and comprising four pixel groups, each of the pixel groups being located within an area defined by two diagonals of the repeat unit, wherein the pixel group comprises:
a first light-emitting pixel group, comprising at least one first sub-pixel and at least one second sub-pixel arranged along one of the diagonals;
a second light-emitting pixel group, comprising at least one first sub-pixel and at least one third sub-pixel arranged along the other of the diagonals, the at least one first sub-pixel in the first light-emitting pixel group and the at least one first sub-pixel in the second light-emitting pixel group being symmetrically distributed about a symmetry line, and the at least one second sub-pixel in the first light-emitting pixel group and the at least one third sub-pixel in the second light-emitting pixel group being symmetrically distributed about the symmetry line; and
a backup pixel group, located adjacent to an edge of the repeat unit and between the first light-emitting pixel group and the second light-emitting pixel group, the backup pixel group at least comprising a second backup sub-pixel and a third backup sub-pixel, the second backup sub-pixel having a same emitting color as the second sub-pixel and the third backup sub-pixel having a same emitting color as the third sub-pixel;
wherein a ratio between a number of the at least one first sub-pixel and a number of the at least one second sub-pixel in the first light-emitting pixel group is 1:1, and a ratio between a number of the at least one first sub-pixel and a number of the at least one third sub-pixel in the second light-emitting pixel group is 1:1.
