Abstract

A printing head module, system and method for printing laser light sources. The printing head module comprises one or more printing heads used for printing a plurality of laser light sources on a substrate successively or once for all; ink used for printing comprises a luminescent dye and a host material, as well as a solvent. The system comprises a printing head module and an ink cartridge; the printing head module is used for inkjet printing the laser light sources on the substrate; the ink cartridge is used for storing ink. By means of the technical solution, industrial manufacturing of the laser light sources is achieved, and speckles caused by laser coherence are eliminated.
