<p>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.</p> |
