Abstract

A method and apparatus for a uniform resolution display screen. In one embodiment, the uniform resolution display screen comprises a surface of the uniform resolution display screen having a curvature configured to display images with a uniform resolution across the display screen. The curvature is based on a projection distance from a projector to the uniform resolution display screen and a viewing distance from an eyepoint of an observer to the uniform resolution display screen. The geometry of the display screen is configured to display images associated with a high definition imaging format.

Claims

1. A uniform resolution display screen comprising:

a surface of the uniform resolution display screen having a curvature configured to display images with a uniform resolution across the uniform resolution display screen, wherein the curvature is based on a projection distance from a projector to the uniform resolution display screen and a viewing distance from an eyepoint of an observer to the uniform resolution display screen; and

a geometry of the display screen, wherein the geometry of the display screen is configured to display images associated with a high definition imaging format.

2. The uniform resolution display screen of claim 1 wherein a worst case resolution of an image displayed on the uniform resolution display screen with a given field of view and a given number of pixels produces the image with a better resolution than a worst case resolution of the image displayed on a flat display screen or a dome shaped display screen with the given field of view and the given number of pixels.

3. The uniform resolution display screen of claim 1 wherein the geometry of the uniform resolution display screen is an n-sided polygon geometry selected from a group consisting of a rectangular geometry, a trapezoidal geometry, or a pentagonal geometry.

4-11. -11. (canceled)

12. A visual display system for use in a simulator comprising:

a set of screens having a selected curvature, wherein the selected curvature is determined using a locus of points created by an intersection of lines drawn at equal angular increments from an eyepoint with a set of lines drawn at equal pixel increments at an image source through a projection point, wherein images displayed on screens in the set of screens having the selected curvature are displayed with uniform resolution; and

a set of projectors, wherein the set of projectors generate images displayed on the set of screens to form a full field of view display.

13. The visual display system of claim 12 wherein the set of screens further comprises:

a top screen; and

a set of side screens, wherein the set of side screens comprises partial side screens, and wherein the set of side screens is tessellated, wherein a geometrically normal ray from a point on a concave side of the spherical surface intersects with a geometric normal ray from a point on a concave side of each other spherical surface near an eye position of an observer.

14. The visual display system of claim 12 wherein the set of projectors generate images on the set of screens with an aspect ratio of approximately sixteen by nine to form a high definition, full field of view display.
