Abstract
A display system useful for achieving a wide field of view infinity effect. The system includes a frame assembly adapted for mounting on a wall of viewing space. The system includes a display element with a display surface. The system includes a magnifying lens supported within the frame assembly with a rear surface facing the display surface and with a front surface facing the viewing space. The rear surface of the magnifying lens is parallel to the display surface of the display element and is separated from the display surface by a separation distance less than a focal length of the magnifying lens, e.g., a value such that a ratio of the separation distance to the focal length is in the range of 0.169 to 0.254. The magnifying lens may be a Fresnel lens in the form of a planar plastic sheet manufactured to provide a flat spherical lens.
