ANTI-BANDING LAYER FOR AUTOSTEREOSCOPIC DISPLAY

摘要

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.
