Title (EN) MULTIBEAM ELEMENT-BASED BACKLIGHTING HAVING CONVERGING VIEWS
(FR) RÉTROÉCLAIRAGE À BASE D'ÉLÉMENTS À FAISCEAUX MULTIPLES À VUES CONVERGENTES
Abstract:
(EN) A multiview backlight and a multiview display employ multibeam elements configured to provide a tilted plurality of light beams having different principal angular directions corresponding to different view directions of a plurality of views of the multiview display. Further, the tilted plurality of light beams has a tilt toward a center of a view zone of the multiview display to provide converging views. The multiview backlight includes a light guide and an array of the multibeam elements. The multiview display further includes multiview pixels that include view pixels to modulate the tilted plurality of light beams having the tilt and the different principal angular directions.
(FR) L'invention concerne un rétroéclairage à vues multiples et un afficheur à vues multiples utilisant des éléments à faisceaux multiples configurés pour fournir une pluralité de faisceaux de lumière inclinés ayant différentes directions angulaires principales correspondant à différentes directions de visualisation d'une pluralité de vues de l'affichage à vues multiples. En outre, la pluralité de faisceaux de lumière inclinée a une inclinaison vers le centre d'une zone de visualisation de l'affichage à vues multiples pour fournir des vues convergentes. Le rétroéclairage à vues multiples comprend un guide de lumière et un réseau des éléments à faisceaux multiples. L'affichage à vues multiples comprend en outre des pixels à vues multiples qui comprennent des pixels de visualisation pour moduler la pluralité de faisceaux de lumière inclinés ayant l'inclinaison et les différentes directions angulaires principales.
