Reflecting projection screen with high gain and wide-visual angle

The reflecting screen is a metal plate, which is passed through pressing, rolling, drawing and grinding to produce high-density parallelly-arranged stripes. The wavy reflecting surface reflects the incident light of the vertical direction to certain direction, and reflects the incident light of horizontal direction expansively, i.e., it provides wide horizontal visual angle or raised screen gain. In addition, the screen is an inner cylinder in the vertical direction, and this produces further raised gain, even brightness, and repulsion to outer light interference.
