Mini LED sorting and arranging method and system

The invention discloses a Mini LED sorting and arranging method and system. The sorting and arranging method comprises the steps of setting an initial position and a grain spacing on a finished product arrangement region, and obtaining virtual absolute coordinates according to the initial position and the grain spacing; selecting initial crystal grains from the sorted crystal grains, wherein the other sorted crystal grains are crystal grains to be arranged, the sorted crystal grains are from at least one wafer, and the initial crystal grains are from the same wafer; and arranging the initial crystal grains according to the virtual absolute coordinates, wherein preset vacancies exist between the initial crystal grains, the crystal grains to be arranged are sequentially arranged on the preset vacancies behind the initial crystal grains, and the crystal grains from the same wafer are separated by the crystal grains from different wafers on the virtual absolute coordinates. According to the sorting and arranging
