Abstract
An autostereoscopic display apparatus includes a matrix display panel (10), preferably an active matrix liquid crystal display panel, having display elements (12) in rows and columns and arranged in groups of at least three adjacent display elements, and an optical director (15) in the form of, for example, a lenticular screen overlying the panel (10) and having lenticules (16) extending in the column direction with each lenticule overlying an associated display element group, in which adjacent display elements in a group are arranged so as to partly overlap one another in the column direction (Y). The display elements in a group can, for example, be arranged in a line in the row direction (X) and shaped as non-rectangular parallelograms, or triangles, successive ones being inverted, or interdigitated, or arranged in two or more rows. As a result, unwanted display artifacts such as dark banding caused by black matrix extending between columns of display elements is eliminated and the transition between stereoscopic views is smoothed due to an image merging effect as a viewer's head moves in the row direction.
