Title
(EN) STATIC MULTIVIEW DISPLAY AND METHOD
(FR) AFFICHAGE MULTIVUES STATIQUE ET PROCÉDÉ
Abstract
(EN)
A static multiview display and method of static multiview display operation provide a static multiview image using diffractive gratings to diffractively scatter light from guided light beams having different radial directions. The static multiview display includes a light guide configured to guide plurality of guided light beams and a light source configured to provide the guided light beam plurality having the different radial directions. The static multiview display further includes a plurality of diffraction gratings configured to provide from a portion of the guided light beams directional light beams having intensities and principal angular directions corresponding to view pixels of the static multiview image.

L'invention concerne un affichage multivues statique et un procédé d'opération d'affichage multivues statique fournissant une image multivues statique à l'aide de réseaux de diffraction pour diffuser de manière diffractive la lumière à partir de faisceaux de lumière guidés présentant des directions radiales différentes. L'affichage multivues statique comprend un guide de lumière conçu pour guider une pluralité de faisceaux de lumière guidés et une source de lumière conçue pour fournir la pluralité de faisceaux de lumière guidés présentant les différentes directions radiales. L'affichage multivues statique comprend en outre une pluralité de réseaux de diffraction conçus pour fournir, à partir d'une partie des faisceaux lumineux guidés, des faisceaux lumineux directionnels présentant des intensités et des directions angulaires principales correspondant aux pixels de visualisation de l'image multivues statique.
