Abstract

An autostereoscopic display provides an extremely deep projection area by observing a relationship between a desired depth of projection and an autostereoscopic display design that includes a focal length of lenticles of a lenticular array and a number of views. The relationship specifies a projected depth at which lenticular crossover can occur for a given autostereoscopic with the specific lenticular focal length and number of views. Approximations can be used to simplify the relationship such that the projected depth is directly related to a product of the focal length and the number of views. To reduce optical aberrations, lenticles of the lenticular array include meniscus-cylinder lenses.

Claims

exact text as granted — not AI-modified

         13 . An electronically controlled dynamic autostereoscopic display comprising:
 an image that contains a number of views; and   a lenticular array that includes at least two lenticles and that is operatively coupled to the image and that makes only one of the views of the image visible from each viewing angle throughout a perceived three-dimensional projection area;   wherein viewing the image through the lenticular array from two different viewing angles simultaneously results in perception of a three-dimensional image in the perceived three-dimensional projection area;   wherein the autostereoscopic display has a width of from 17 to 35 inches; and   wherein the ratio of (i) four times the product of a focal length of the lenticles and the number of views to (ii) the width of the autostereoscopic display is at least 0.25:1.   
     
     
         14 . The autostereoscopic display of  claim 13  wherein the autostereoscopic display displays video content having a 1080p display format. 
     
     
         15 - 16 . (canceled) 
     
     
         17 . The autostereoscopic display of  claim 13  wherein the autostereoscopic display displays video content having a WQXGA display format; and
 wherein the ratio of (i) four times the product of a focal length of the lenticles and the number of views to (ii) the width of the autostereoscopic display is at least 1:1. 
 
     
     
         18 - 25 . (canceled) 
     
     
         26 . A static autostereoscopic display comprising:
 an image that contains a number of views; and   a lenticular array that includes at least two lenticles and that is operatively coupled to the image and that makes only one of the views of the image visible from each viewing angle throughout a perceived three-dimensional projection area;   wherein viewing the image through the lenticular array from two different viewing angles simultaneously results in perception of a three-dimensional image in the perceived three-dimensional projection area;   wherein the autostereoscopic display has a width of at least 28 inches; and   wherein the ratio of (i) four times the product of a focal length of the lenticles and the number of views to (ii) the width of the autostereoscopic display is at least 0.6:1.   
     
     
         27 - 55 . (canceled) 
     
     
         56 . An autostereoscopic display comprising:
 an image that contains a number of views; and   a lenticular array that includes at least two lenticles and that is operatively coupled to the image and that makes only one of the views of the image visible from each viewing angle throughout a perceived three-dimensional projection area;   wherein viewing the image through the lenticular array from two different viewing angles corresponding to an intraocular distance of 2.4 inches simultaneously results in clear perception of a three-dimensional image in the perceived three-dimensional projection area from a viewing distance of at least 48 inches; and   wherein the ratio of (i) four times the product of a focal length of the lenticles and the number of views to (ii) the width of the autostereoscopic display is at least 0.1:1.   
     
     
         57 . The autostereoscopic display of  claim 56  wherein the ratio of (i) four times the product of a local length of the lenticles and the number of views to (ii) the width of the autostereoscopic display is at least 0.2:1. 
     
     
         58 - 62 . (canceled) 
     
     
         63 . The autostereoscopic display of  claim 56  wherein the autostereoscopic display is an electrically controlled dynamic display; and
 wherein the ratio of (i) four times the product of a focal length of the lenticles and the number of views to (ii) the width of the autostereoscopic display is at least 0.25:1. 
 
     
     
         64 . The autostereoscopic display of  claim 63  wherein the autostereoscopic display displays video content having a 1080p display format.
