Abstract

The application discloses an optical engine module and a laser projection device, and belongs to the laser projection field.The optical engine module comprises a light source assembly, a prism assembly, a light valve assembly and a lens assembly, wherein the light valve assembly at least comprises a first light valve and a second light valve, the prism assembly is used for guiding the incident light corresponding to each light valve to the corresponding light valve respectively, and guiding the light beams output by each light valve to the lens assembly, the image light beams output by the first light valve and the image light beams output by the second light valve are dislocated at the irradiation position of the lens assembly, so that the resolution of the image picture projected by the lens assembly can be improved without setting a vibrating mirror, the structural components of the optical engine module are less and the volume of the optical engine module is small, the problem that the components of the optical engine module are more and the volume of the optical engine module is large in the related art can be solved, and the effects of simplifying the structure of the optical engine module and reducing the volume of the optical engine module are achieved.
