LASER PROJECTION LIGHT SOURCE MODULE AND BEAM SHAPING METHOD THEREOF AS WELL AS LASER DISPLAY EQUIPMENT

摘要

A laser projection light source module and a beam shaping method thereof as well as a laser display equipment are disclosed. The laser projection light source module comprises a first laser module (10) for emitting the first beam, a second laser module (20) for emitting the second beam, a third laser module (30) for emitting the third beam, and an optical coupler for receiving the first beam, the second beam and the third beam, and coupling the first, second and third beams into a first coupling beam, wherein the first laser module, the second laser module and the third laser module are the laser modules with different colors. The speckle reduction effect of the laser projection light source module can be improved.
