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.

Abstract: A laser panel, a laser array device, and a laser display. The laser panel and the laser array device separately comprise multiple groups of independent laser light source modules; each group of laser light source modules comprises plural light sources; the plural light sources are all produced by inkjet printing; the laser display and a voltage-driven laser display separately comprise the laser panel. Producing a laser panel by inkjet printing provides a novel technical solution for cheap and industrial manufacturing of laser panels. It is difficult to generate laser coherent superposition between the light emitted by the laser light source module, and therefore, speckles caused by laser coherence in conventional laser display technologies are greatly eliminated. The present invention achieves a voltage-driven laser display, and facilitates achieving a better display effect while reducing the volume of the display.

Abstract: Ink for producing laser light sources. The ink is used for inkjet printing to produce laser light sources of a certain scale. The ink comprises a luminescent dye, a host material, and a solvent. The use of the ink makes it possible to produce laser light sources through inkjet printing. This provides a novel technical solution for cheap and industrial manufacturing of laser light sources and other related products through inkjet printing.
