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.
Background
BACKGROUND 1. Field of the Description (1) The present description relates, in general, to display systems configured to display content that includes objects and features that are at a great distance from the viewer or at infinity. More particularly, the description relates to a display system that provides a window or portal that can be mounted within a wall of a facility (or in a small packaging application with only a small amount of depth available) but yet provide an infinity effect for content displayed to a plurality of viewers in a room including the wall over a wide field of view. 2. Relevant Background (2) There are numerous applications where it is desirable to provide infinity optics or an infinity effect for displayed content. The 'infinity effect' is an optical illusion that causes nearby images or displayed content to appear as if they go on forever or that some of the displayed objects are actually located at infinity or at a great distance from the viewer. The infinity effect is provided in flight simulators such as for training fighter jet pilots. However, the conventional infinity optics utilized require a great deal of space (e.g., 4 to 6 feet or more) to implement and are very costly. Additionally, the infinity effect achieved often has a very small field of view (fov) requiring the viewer's eyes to be located in a particular position relative to the infinity optics that cannot change over time or that is fixed (e.g., the pilot in training remains in a s
