Title (EN) MULTILAYER REFLECTOR FOR DIRECT LIT BACKLIGHTS
(FR) RÉFLECTEUR MULTICOUCHE POUR RÉTROÉCLAIRAGES À ÉCLAIRAGE DIRECT
Abstract:
(EN) Disclosed herein are light guide assemblies comprising a backlight unit having a substrate comprising a light emitting first major surface and an opposing second major surface, at least one light source optically coupled to the substrate, and a reflector positioned proximate first or second major surface of the substrate, the reflector comprising two or more layers of a reflective material with each of the layers having a first area and a second area, the first area being more reflective than the second area, and the second area being more transmissive than the first area.
(FR) La présente invention concerne des ensembles guides de lumière comprenant une unité de rétroéclairage ayant un substrat comprenant une première surface principale émettant de la lumière et une seconde surface principale opposée, au moins une source de lumière optiquement couplée au substrat, et un réflecteur positionné à proximité d'une première ou d'une seconde surface principale du substrat, le réflecteur comprenant deux couches ou plus d'un matériau réfléchissant, chacune des couches ayant une première zone et une seconde zone, la première zone étant plus réfléchissante que la seconde zone, et la seconde zone étant plus transmissive que la première zone.
