AN OPTICAL SHEET AND A REFLECTION TYPE HIGH GAIN PROJECTION SCREEN USING THE SAME

摘要

projection angle of the center and the left and right side in a wide reflective screen image to the left and right images to be projected from a point source this varies the brightness difference arises in the lateral direction on the cut surface is the surface of the screen by combining adjacent to solve the three-dimensional pattern of the left and right two fan-shaped triangle and fine machining tank 1 as a semi-transparent or transparent resin , and the optical sheet problem and high-intensity reflective screen with this
