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.
Claims10
A method for designing a stereoscopic display, comprising:
- selecting a depth of a projection area, wherein the projection area is generated by a lenticular array, comprising at least two lenticles, operatively coupled to a display;
- identifying a number of views comprised within the display, wherein a view comprises a subset of an image;
- and
- identifying a distance from a portion of the display to at least one of the lenticles, wherein the at least one of the lenticles is a lenticle that the portion of the display is shown through, wherein the distance from the portion of the display to at least one of the lenticles establishes a minimal amount of lenticular crosstalk;
- wherein one of:
- the identifying a number of views and identifying a distance is computed via the calculation:
- 2d=4nvf;
- wherein d is the depth of the projection area, wherein nv is the number of views, and wherein f is the distance.
