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.
