TLDR
In this paper, the alignment features of the apertures of each individual pixel are offset from one another in a direction perpendicular to said geometric axes, which improves angular contrast uniformity and improves angular intensity uniformity.Abstract:
An autostereoscopic display apparatus includes a spatial light modulator in which alignment features such as bump features provide radially symmetric alignment of the molecules of the liquid crystal. A parallax element is arranged over the spatial light modulator to direct light from the pixels into different viewing windows. The apertures of the pixels are shaped such that, for each individual row of pixels, a notional line parallel to the geometric axes of the parallax elements has a total length of intersection with the pixels of the row, weighted for the intensity of light modulated by the alignment features, which is the same for all positions of the notional line. This improves angular intensity uniformity. The pixels may each include plural apertures, wherein the alignment features of the apertures of each individual pixel are offset from one another in a direction perpendicular to said geometric axes. This improves angular contrast uniformity.read more

Autostereoscopic Rendering and Display Apparatus
Abstract: An apparatus comprising a sensor configured to detect the position and orientation of a user viewpoint with respect to an auto-stereoscopic display; a processor configured to determine a surface viewable from the user viewpoint of at least one three dimensional object; and an image generator configured to generate a left and right eye image for display on the auto-stereoscopic display dependent on the surface viewable from the user viewpoint.
