Abstract
Official abstract text for this publication.
An autostereoscopic display device comprises a display arrangement such as an emissive display arrangement or an reflective display arrangement, with an array of spaced pixels. A light guiding arrangement has an array of light guide columns, with one column over each display pixel or over a group (such as a column) of pixels. The light guide columns comprise aside wall which tapers outwardly to define a funnel shape with the pixel at the smaller base of the funnel. The funnel provides collimation to reduce cross talk in the display, which is particularly problematic for 3D autostereoscopic displays.
First claim
Opening claim text (preview).
The invention claimed is: 1. An autostereoscopic display device comprising: a display arrangement comprising an array of spaced pixels; a light guiding arrangement comprising an array of light guide columns, with one light guide column over each display pixel or a group of pixels, wherein the light guide columns comprise a side wall which tapers outwardly to define a funnel shape with the pixel or pixels at the smaller base of the funnel; and an autostereoscopic lens arrangeme…
