A stereoscopic 3D liquid crystal display module includes a liquid crystal display panel and a directional backlight positioned to provide light to the liquid crystal display panel. A double sided prism film is disposed between the liquid crystal display panel and the directional backlight. The prism film includes a first surface having a series of cylindrical lenses adjacent the liquid crystal display panel and a second surface, opposite the first surface, having a series of non-contiguous prisms adjacent the directional backlight. Each of the non-contiguous prisms is separated from adjacent prisms by a transmissive flat portion or an opaque portion.

A backlight for a stereoscopic D liquid crystal display apparatus includes a light guide having a light emission surface and an opposing light extraction surface, a first side extends between the light emission surface and the light extraction surface, and a second side extends between the light emission surface and the light extraction surface, the second side opposing the first side. A centerline extends parallel to the first side and second side and is equidistant from the first side and the second side. A center elongated prism extends along the centerline and forms a portion of the light extraction surface. A plurality of elongated prisms extend parallel to the center elongated prism wherein the prisms are progressively more canted for each subsequent elongated prism further from the center elongated prism. A plurality of light sources disposed along the first side and the second side.

Methods of reducing perceived image crosstalk in a multiview display. One method includes providing an image stream to a display having a horizontal dimension that extends from a first side of the display to an opposing second side of the display. The image stream includes a temporal sequence of images where at least a first image view and then a second image view are displayed on the display in a time sequential manner. The temporal sequence of images are conditioned before being displayed in order to reduce perceived displayed image crosstalk between the first and second image views. The conditioning includes modifying a color intensity of at least selected pixels along the horizontal dimension based on a non-constant crosstalk correction function for the horizontal dimension.

Optical films used for 3D autostereoscopic displays include lenses on one surface of the optical film that are registered to prisms on the opposing surface of the optical film. The lenses may be a-cylindrical lenses or cylindrical, and the rotation of the lenses can vary with position on the surface of the optical film. The prisms may be contiguous or non-contiguous. The prisms of the optical film can have a pitch that is different from a pitch of the lenses, or the prism pitch can be substantially the same as the pitch of the lenses.

Stereoscopic displays and backlights include a light guide with individually addressable light sources disposed at opposite edges of the light guide, and a light redirecting film disposed in front of the light guide. Light from one light source is emitted from the backlight as a right eye elongated light beam, and light from the opposite light source is emitted as a left eye elongated light beam. Structured surface features, e.g. linear prismatic or linear lenticular features, on the light guide and/or the light redirecting film are oriented such that the elongated light beams are offset from an optical axis of the backlight. Moreover, each of the elongated light beams is oriented to intersect both a first observation plane and a second observation plane perpendicular to the first observation plane, the first observation plane defined by the optical axis and an in-plane axis along which the light sources are disposed.

A manufacturing system includes a sensing system that provides high-resolution feedback for web guiding and tension control. The system may be especially useful for web material that is manufactured to include micro-replicated structures with micron size scale. A micro-replication station forms a pattern of micro-replicated lenses on a web material. The sensing system illuminates a measurement area on the web material and detects an angular distribution of light exiting a set of the micro-replicated lenses within the first measurement area. A control system that adjusts at least one process control parameter of the transport system based on the detected angular distribution.
