AUTOSTEREOSCOPIC DISPLAY |
摘要 |
<p>Apparatus and method for the display of autostereoscopic images, in which two or more perspective views are generated by a single transmissive display screen, is provided. A structured light source behind the screen directs light through different sets of display elements to correspondingly different viewing zones. In certain embodiments, the structured source comprises a patterned mask which prevents light from passing through a particular set of elements and reaching the wrong zone. The pattern of the mask may be programmed. Observer co-ordinate data permits the correct viewing zone to be co-located with each of the observer's corresponding eyes. A tapered lenticular structure can provide the means for adapting to changes in the observer's distance from the display. In further embodiments a holographic optical element (HOE) may be used instead of an array of conventional lens elements. The HOE typically incorporates the function of providing in conjunction with a suitably located light source the viewing zones required for respective sets of display elements. The display may also be used to provide conventional two-dimensional images at the display screen's full resolution.</p> |
