Sorting method and system for light-emitting chips

According to the sorting method and system for the light-emitting chips, the mother BIN for sorting the same light-emitting wafer is subdivided into more child BINs, then the light-emitting chips corresponding to the child BINs are sorted to the corresponding mother BIN square pieces for die bonding according to the preset die bonding diagram, and therefore the light-emitting wafers are sufficiently mixed and sorted, and the light-emitting chips are sorted more accurately. Therefore, the photoelectric performance consistency of different square sheets obtained by the same light-emitting wafer is high, the uniformity of the display brightness of the whole screen of the display screen is improved, and the display effect of the display screen is improved. 本发明提供了一种发光芯片的分选方法及系统，将同一发光圆片分选的母BIN细分为更多的子BIN，而后将子BIN对应的发光芯片按照预设固晶图分选至对应母BIN方片上固晶，由此将发光圆片进行充足的混分，使得由相同发光圆片得到的不同方片的光电性能一致性高，提高了显示屏的整面屏显示亮度的均匀性，提高了显示屏的显示效果。
