Abstract
A compact projector includes a main control board, an optical engine positioned on the main control board, a heat dissipation assembly, a light source control board, and a digital-micromirror-device control board. The optical engine includes a light-shading member and a projection lens module. The light-shading member includes a first plate and a second plate. The first plate and the projection lens module are approximately perpendicular to the second plate to form a U-shape. The heat dissipation assembly is positioned adjacent to the first plate. The light source control board is positioned on one side of the main control board adjacent to the second plate. The digital-micromirror-device control board is positioned on one side of the main control board perpendicular to the light source control board.
