4 . The autostereoscopic display system of claim 1 , further comprising establishing a baseline design for the lenticular screen and wherein the baseline design for the lenticular screen is altered such that the main focal point of the lenticular screen is located behind the front surface of the electronic display.
5 . The autostereoscopic display system of claim 4 , wherein the distance fixed between the front surface of the electronic display and the lenticular screen comprises the lenticular sheet produced at a thickness such that the main focal point is located behind the front surface of the electronic display.
6 . The autostereoscopic display system of claim 4 , wherein the distance fixed between the front surface of the electronic display and the lenticular screen comprises lenticule curvature of the lenticular sheet produced at a radius such that the main focal point is located behind the front surface of the electronic display.
7 . The autostereoscopic display system of claim 1 , wherein the front surface of the electronic display comprises a plurality of pixels, and wherein the main focal point is located behind the front surface of the plurality of pixels.
8 . A method for displaying autostereoscopic images on a display having a front surface and a lenticular screen associated therewith, the method comprising:
establishing a distance between the front surface of the electronic display and the lenticular screen such that a focal point established by the lenticular screen is positioned behind the front surface of the electronic display.
9 . The method of claim 8 , further comprising creating a baseline lenticular screen design prior to said establishing wherein a baseline focal point is positioned in front of the front surface of the electronic display, and wherein said establishing comprises altering the baseline lenticular screen design comprises altering the lenticular screen design to move the focal point behind the front surface of the electronic display.
10 . The method of claim 8 , wherein establishing comprises producing the lenticular sheet at a thickness such that the main focal point is located behind the front surface of the electronic display.
11 . The method of claim 8 , wherein establishing comprises producing a lenticular sheet having individual lenticule radius of curvature such that the main focal point is located behind the front surface of the electronic display.
12 . The method of claim 9 , wherein establishing comprises producing the lenticular sheet at a thickness such that the main focal point is located behind the front surface of the electronic display.
13 . The method of claim 9 , wherein establishing comprises producing a lenticular sheet having individual lenticule radius of curvature such that the main focal point is located behind the front surface of the electronic display.
14 . The method of claim 8 , wherein the front surface of the electronic display comprises a plurality of pixels, and wherein the main focal point is located behind the front surface of the plurality of pixels.
15 . An autostereoscopic display system comprising:
an electronic display comprising a front surface;
a lenticular sheet in juxtaposition with said electronic display;
wherein a distance between the front surface of the electronic display and the lenticular screen is established such that a main focal point for the system is located behind the front surface of the electronic display.
16 . The autostereoscopic display system of claim 15 , wherein the distance established between the front surface of the electronic display and the lenticular screen comprises the lenticular sheet produced at a thickness such that the main focal point is located behind the front surface of the electronic display.
