Abstract
An autostereoscopic display comprises an SLM which is controlled to provide an image display and a signal display. A parallax optic has a first portion which cooperates with the image display to form a plurality of viewing windows. A second portion of the parallax optic forms first and second images visible to an observer to allow the observer to distinguish between a desired orthoscopic viewing zone and undesirable viewing positions such as pseudoscopic positions. The pitch of parallax elements in the second portion is one and a half times the parallax element pitch in the first portion.
Claims21
An autostereoscopic display comprising an image display, a signal display, and a parallax optic having a first portion, which cooperates with said image display to form a plurality of right and left eye viewing zones in a viewing region, and a second portion, which cooperates with said signal display to form a first signal image which is visible in at least one first part of said viewing region and a second signal image which is visible in at least one second part of said viewing region, said first portion comprising an array of parallax elements having a first pitch in a first direction, and said second portion comprising an array of parallax elements having a second pitch substantially equal to one and a half times said first pitch in said first direction.
