Title (EN) BACKLIGHT SYSTEM
(FR) SYSTÈME DE RÉTROÉCLAIRAGE
Abstract:
(EN) An optical system comprises a light source emitting light, a collimating structure to substantially collimate the light, a converter unit to receive the substantially collimated light having an area illuminating a first aspect ratio and outputting light having an area illuminating a second aspect ratio, the second aspect ratio greater than the first aspect ratio by at least a factor of four, and a backlight light guide to receive the light from the converter unit.
(FR) L'invention concerne un système optique qui comprend une source de lumière émettant de la lumière, une structure de collimation pour collimater sensiblement la lumière, une unité de conversion pour recevoir la lumière sensiblement collimatée ayant une zone éclairant avec un premier rapport d'aspect et émettant une lumière ayant une zone éclairant avec un second rapport d'aspect, le second rapport d'aspect étant supérieur au premier rapport d'aspect d'au moins un facteur de quatre, et un guide de lumière de rétroéclairage pour recevoir la lumière provenant de l'unité de conversion.
