Problems solved by technology

[0002] For the laser field, on the one hand, the existing laser display technology, due to the laser speckle caused by the interference effect of strong laser coherence, seriously reduces the display quality, and has to use methods such as vibration screen to eliminate speckle
On the other hand, the prior art lacks a technology for rapidly and mass-manufacturing laser light sources and enabling each light source to emit laser light of different colors

Abstract

A printhead module for printing laser light sources comprises: one or more printheads for printing multiple laser light sources on a substrate in sequence or once; the ink used for the printing comprises a luminescent dye, a matrix material and a solvent. The technical solution disclosed by the invention firstly makes the laser light sources by inkjet printing, which provides a new technical solution for inexpensive and industrial manufacture of various laser light sources and other related products; secondly, since the laser light sources are convenient to achieve a module including multiplegroups of independent laser light sources, each group of laser light source modules is enabled to be independent from each other when they emit light, and laser coherence between the emitted light isavoided, thereby greatly eliminating speckle caused by common laser coherence.

Description

technical field [0001] The invention relates to the field of laser light sources, in particular to a printing head module for printing laser light sources. Background technique [0002] For the laser field, on the one hand, the existing laser display technology, due to the laser speckle caused by the interference effect of strong laser coherence, seriously reduces the display quality, and has to use vibration screen and other means to eliminate the speckle. On the other hand, the prior art lacks a technology for rapidly and mass-manufacturing laser light sources and enabling each light source to emit laser light of different colors. Contents of the invention [0003] In order to solve the above problems, the present invention (herein, the present invention has the same concept as the present disclosure) provides a print head module for printing a laser light source, including: [0004] One or more print heads for printing multiple laser light sources sequentially or at on...
