ABSTRACT:
A portable projector is disclosed. The portable projector comprises a light transmission member having first and second surfaces, a multi-type laser light source including a plurality of sub laser light sources for emitting light beams onto the first surface of the member based on an external image signal, so as to allow the light beams to be transmitted into the member, one or more optical elements supported on at least one of the first and second surfaces of the member for diffracting and reflecting the light beams incident from the multi-type laser light source into the member, and at least one multi-type scan mirror supported on one of the first and second surfaces of the member for scanning the light beams diffracted and reflected from the optical elements onto an external screen located at the outside of the member, based on an external control signal.
