摘要： Embodiments of the present application provide a laser light source and a laser projection device. The laser light source includes a laser assembly and a light combination mirror assembly. The laser assembly includes at least a laser, a light emitting surface of the laser has a plurality of light emitting regions, and beams emitted from different ones of the plurality of light emitting regions are in different colors. The light combination mirror assembly includes a plurality of mirrors that are sequentially arranged along an optical transmission path of the laser, with each of the mirrors corresponding to one of the light emitting regions. The light combination mirror assembly is used to converge the beams in different colors emitted from the laser to form a white beam.

摘要： A projection screen includes a screen board, a connecting cloth, a screen frame, and at least one connecting member. The screen board has a first surface and a second surface opposite, the screen board has a light receiving region and an edge region surrounding the light receiving region. At least one edge of the connecting cloth protrudes from a corresponding edge of the screen board, and at least a portion of the second surface of the screen board located in the edge region is connected to the connecting cloth. The screen frame has a hollow structure, an orthographic projection of the screen board on a plane parallel to the first surface is located within an outer border of an orthographic projection of the screen frame on the plane. The at least one connecting member connects at least one edge of the connecting cloth to the screen frame.
