ABSTRACT:
This system is designed for video displays that are used for television presentation or film projection, so as to reduce eyestrain, glare from light reflections, and will increase contrast and apparent brightness, making the presentations more readable, and will reduce all potentially harmful radiation effects from the cathode ray tube, which may be cumulative. Primarily, the system consists of an elevated cathode ray tube in the display housing, which produces its image on an inner frontal plane mirror where the image is projected onto and inner spherical morror that reflects the image through a housing cover glass to be seen by the user.
