Abstract:
1. An optical combiner module, disposed in an intersection of a plurality of color lights split by a beam splitter module, the optical combiner module comprising: a combiner, comprising at least a pared-corner, wherein the combiner is substantially a regular hexahedron, at least one corner of the combiner is cut to form at least one lean surface, the lean surface is connected to a top surface or a bottom surface of the combiner, and an angle between the lean surface and the top surface or the bottom surface is larger than 0°; a plurality of prisms, disposed adjacent to the combiner, wherein one side of one of the prisms is leaned adjacent to the pared-corner of the combiner; and a plurality of light valves for forming the image, respectively disposed in a path of the color lights after the prisms, wherein the color lights are reflected to the light valves by a total reflection plane of each of the prisms respectively and said color lights reflected by the light valves are transmitted through the prisms and thereafter are combined by the combiner.
