Display system and motion simulator typically using light-emitting diodes

摘要

A display system employs an active image-generating screen (102) that presents a video image. The screen contains a plurality of block facets (112), each containing a plurality of light-emissive modules (114) preferably implemented with LEDs. Each light-emissive module is configured so that the maximum intensity of that module's light emission occurs along a direction (138) materially non-perpendicular to the back surface (136) of the module's supporting body (130). The modules are arranged so that their maximum light-intensity directions are largely the same. The block facets are configured to approximate a convex curved surface. The maximum light-intensity directions (158) of the block facets are thereby materially slanted relative to one another. Arranging the display system in this manner enables the light-processing efficiency to be very high. A motion simulator, such as a flight simulator, is formed by combining the screen with a reflective collimator (104).

主权项

1. A structure comprising a plurality of light-emissive components connected together for generating an image, each light-emissive component having a light-providing surface and a further surface, referred to as the back surface, generally opposite the light-providing surface, light emitted from each light-emissive component emanating from its light-providing surface with an intensity having a maximum that occurs in a maximum light-intensity direction materially non-perpendicular to that component's back surface, the components' back surfaces being materially slanted relative to one another so as to approximate a three-dimensional convex curved surface whereby the components' maximum light-intensity directions are materially slanted relative to one another.
