Title (EN) FRONTLIGHT SYSTEM WITH MULTIPLE ANGLE LIGHT-TURNING FEATURES
(FR) SYSTÈME ÉCLAIRÉ PAR L'AVANT COMPRENANT DES ÉLÉMENTS DE ROTATION DE LUMIÈRE À ANGLES MULTIPLES
Abstract:
(EN) This disclosure provides systems, methods and apparatus for light-guiding layers including light-turning features with multiple reflective surfaces oriented at different angles to the light-guiding layer. In one aspect, the multiple reflective surfaces may be located on each individual light-turning feature, while in another aspect, the multiple reflective surfaces may be located on separate light-turning features. The use of multiple reflective surfaces oriented at different angles can improve the efficiency and appearance of a frontlight system using such a light-guiding layer.
(FR) La présente invention concerne des systèmes, des procédés et un appareil pour des couches de guidage de lumière comprenant des éléments de rotation de lumière présentant de multiples surfaces réfléchissantes orientées selon des angles différents par rapport à la couche de guidage de lumière. Dans un aspect de l'invention, les multiples surfaces réfléchissantes peuvent être situées sur chaque élément de rotation de lumière individuel, tandis que dans un autre aspect de l'invention, les multiples surfaces réfléchissantes peuvent être situées sur des éléments de rotation de lumière distincts. L'utilisation de multiples surfaces réfléchissantes orientées selon des angles différents permet d'améliorer l'efficacité et l'aspect d'un système éclairé par l'avant utilisant une couche de guidage de lumière.
