Abstract

L'invention vise à fournir une feuille optique qui supprime le besoin en film de diffusion optique et se distingue par une résistance élevée et une qualité d'image haute définition sous une forme discrète avec combinaison intégrée d'une feuille lenticulaire et d'une couche de diffusion optique, et à fournir une unité de rétroéclairage et un appareil d'affichage utilisant la feuille optique. Une unité de rétroéclairage et un appareil d'affichage utilisent des premières matrices lenticulaires (3) formées sur un matériau de substrat, un plan d'incidence optique (102) pour une feuille lenticulaire (1) ayant des secondes matrices lenticulaires (5) formées sur chacune des premières matrices lenticulaires (3), et une feuille optique (25) qui intègre la feuille lenticulaire (1) et la couche de diffusion optique (25) sur une distance d'un plan de sortie optique (101) d'une plaque de diffusion optique (25) au moyen d'un ou de plusieurs éléments de fixation (39).
