Abstract: An autostereoscopic display (140) is provided comprising i) a display panel (142) providing a display output composed of pixels in an array and ii) an optical stack (150) arranged at a display side of the display panel. The optical stack comprises a lenticular means (170) and an anti- banding layer (190). The lenticular means (170) comprises a profiled surface, the profiled surface defining an array of lenticular elements for directing the outputs from respective groups of said pixels in mutually different directions so as to enable a stereoscopic image to be perceived. The anti- banding layer (190) is arranged for effecting a variation in the refraction of light along a periphery (176, 177) of each lenticular element (170). The above optical stack (150) can reduce repeating patterns in autostereoscopic displays and/or the visibility of such repeating patterns to the viewer.

Abstract: A system and method are provided for measuring a rotational position of a lenticular lens sheet (020), which involves a light source (120) emitting light onto at least part of a surface of the lenticular lens sheet, a camera (140) capturing an image of the light reflected (040) by, or transmitted (042) through, the surface, thereby obtaining an image showing a light pattern (060), and a processor (160) determining the rotational position of the lenticular lens sheet relative to a coordinate system associated with the image based on an analysis of the light pattern in the image. Accordingly, the rotational position of the lenticular lens sheet may be determined from an analysis of the captured image of the light emitted from the light source that is reflected or transmitted by the lenticular lens sheet. It is therefore not needed to use specially prepared images nor markers.

Abstract: In an autostereoscopic display (100), an optical panel (200) is mounted as follows. A support frame (300) is provided which defines a framed opening for holding the optical panel in place along a periphery of the optical panel. The framed opening is larger than the optical panel in at least one dimension. As such, when the optical panel is inserted in the framed opening, at least one gap (DT) is formed between the support frame and the optical panel. A spacing member (400-420) is provided which is inserted into the gap to establish a structural connection (600) between the optical panel and the support frame by bridging a width of the gap. The spacing member may be formed by a pair of wedges (400, 410) which are arranged for, after being inserted into the gap (DT), mutually engaging to establish the structural connection that bridges the width of the gap. The spacing member provides improved mounting of an optical panel in an autostereoscopic display. In particular, the spacing member enables stress exerted by the optical panel, e.g., due to gravity, to be transferred the support frame instead of to more fragile parts of the autostereoscopic display such as the display panel. Another advantage is that the spacing member can be positioned freely along a length of the gap, thereby providing a flexible manner of mounting the optical panel to the support frame.
