ABSTRACT:
An improved active matrix reflective projection system utilizing a conventional wafer includes a reflective image plane module forming two focal images. The image plane module includes light directing and reflecting structures and a wafer based active matrix. A source of light is directed to the image plane module active matrix from a first image plane. The active matrix imparts information onto a light beam reflected therefrom. The image plane module projects the reflected beam for viewing, such as through one or more lens. The active matrix reflective projection system can be a monochrome projector including a single reflective image plane module or can be a full color system including three reflective image plane modules. Each color image plane module operates on a single color component, red, green or blue, which then are combined on a screen or before projecting on the screen to form the full color projection image. The active matrix includes a specular reflective back surface and an LC or similar type material formed thereon which is electronically altered to impart the information to the light beam reflected therefrom. The image plane module includes a mirror or mirror portion which directs the light or light component to the wafer based active matrix which reflects an encoded light beam therefrom and which projects the reflected light to be viewed.
