Autostereoscopic display system having reduced moiré effects

Abstract

An autostereoscopic display of an autostereoscopic display system can include a display panel having regularly spaced pixels, such as an array of regularly spaced light-emitting diodes, and a parallax-generating optic, such as a lenticular lens or a parallax barrier, that can direct light from the display panel to a viewer. The parallax-generating optic can have elongated parallax-generating features that extend along respective elongated feature paths. At least some of the elongated feature paths can deviate, by respective displacements, from respective nominal feature paths that are linear and regularly spaced within a surface area of the parallax-generating optic. For example, the elongated feature paths can be linear and parallel to the nominal feature paths, with displacements that are random within a specified range, optionally with pseudorandom variation. The displacements can reduce Moiré effects in the autostereoscopic display when the autostereoscopic display is viewed by the viewer.
