Parallax autostereoscopic 3D picture and autostereoscopic 3D display

摘要

A parallax barrier comprises a plurality of parallel vertical apertures or apertures. In a direction transverse to the apertures, the apertures have an optical transmission function which comprises a plurality of sub-apertures so that the function varies in this direction. In general, the function is constant in a direction parallel to the apertures or apertures. Such a barrier may be used with a spatial light modulator such as a liquid crystal display to form an autostereoscopic 3D display.
