Title (EN) MICROSTRUCTURED AND PATTERNED LIGHT GUIDE PLATES AND DEVICES COMPRISING THE SAME
(FR) PLAQUES DE GUIDAGE DE LUMIÈRE À MICROSTRUCTURES ET À MOTIFS, ET DISPOSITIFS LES COMPRENANT
Abstract:
(EN) Disclosed herein are light guide plates (100, 100`, 100``) comprising a transparent substrate (110) having an edge surface (150), a light emitting first major surface (160), and an opposing second major surface (170); and a polymeric film (120) disposed on at least one of the first (160) and second (170) major surfaces of the transparent substrate, wherein the polymeric film (120) comprises a plurality of microstructures (130) and/or a plurality of light extraction features. At least one light source (140) may be coupled to the edge surface (150) of the transparent substrate (110). Display and lighting devices comprising such light guide plates are further disclosed, as well as methods for manufacturing such light guide plates.
(FR) L'invention concerne des plaques de guidage de lumière (100, 100`, 100``) comprenant un substrat transparent (110) comportant une surface de bord (150), une première surface principale émettant de la lumière (160) et une seconde surface principale opposée (170) ; et un film polymère (120) disposé sur les première et/ou seconde surfaces principales du substrat transparent, le film polymère (120) comprenant une pluralité de microstructures (130) et/ou une pluralité de caractéristiques d'extraction de lumière. Au moins une source de lumière (140) peut être couplée à la surface de bord (150) du substrat transparent (110). L'invention concerne en outre des dispositifs d'affichage et d'éclairage comprenant de telles plaques de guidage de lumière, ainsi que des procédés de fabrication de telles plaques de guidage de lumière.
