Title
(EN) COMPLEX PRISM SHEET
(FR) FEUILLE DE PRISME COMPLEXE
Abstract
(EN) This invention relates to a complex prism sheet which is configured such that heat-resistant coating layers are formed on both surfaces of a substrate layer, thus preventing wrinkling or curling of the complex prism sheet due to heat generated from a light source, and increasing concealment and electro-optic characteristics, ultimately improving properties of a light crystal display. This complex prism sheet can be usefully applied to television (TV) sets, monitors, notebook personal computers (NBPCs), etc., which are required to have heat resistance, slimness and concealment because of an increasing use of a light emitting diode (LED) light source these days.
(FR) La présente invention concerne une feuille de prisme complexe qui est configurée de telle sorte que des couches de revêtement thermorésistantes sont formées sur les deux surfaces d'une couche de substrat, empêchant ainsi un plissement ou un cintrage de la feuille de prisme complexe en raison d'une chaleur générée depuis une source lumineuse, et augmentant des caractéristiques de dissimulation et électro-optiques, améliorant finalement des propriétés d'un dispositif d'affichage à cristaux liquides. Cette feuille de prisme complexe peut être appliquée de façon utile à des postes de télévision (TV), des moniteurs, des ordinateurs personnels bloc-notes (NBPC), etc., qui ont besoin d'avoir une résistance thermique, une minceur et une dissimulation en raison d'une utilisation croissante d'une source lumineuse de diode électroluminescente (DEL) de nos jours.
