Abstract
A parallax optic comprises plural, spaced apart lenses which are separated by regions which are non-transmissive of/to visible light. In some embodiments, the spaced apart lenses of the parallax optic are discrete elements of a lens array. In other embodiments, the lens elements are formed as convex elements integral with and extending from a lenticular layer. Parallax optic devices are combined with one or more image display elements to form an image display device. For embodiments of image display devices featuring or providing two-dimensional (2D) viewability, the parallax optic is preferably near or included in the image display element. On the other hand, for embodiments of image display devices featuring or providing three-dimensional (3D) viewability, the parallax optic is situated outside the image display element.
