Insert diode lamps of different colors into the holes of the PCB to form pixels. It is often said that the pixel pitch is the distance between two lamps, and the resolution is the number of lamps per unit area. Diodes are mainly Silan, Dalian Lumei, American cree, Guanglei, AXT, AOC; standard specifications for luminescent film are generally 12mell, G and B are 14mell.
Note: a. In the direction of the lamp, do not insert the reverse b. Do not plant less, wrong plant c. Check the diode itself for problems. QC detection
