    • Disclosed is an optical film having an optical structure, such as a prism film or sheet, which is a constituent of a backlight unit. The optical film includes an optical structure layer having a plurality of optical structures, the surface of which is formed with irregularities, and the irregularities are formed on the surface of the light-collecting optical structure, such as a prism, to satisfy predetermined conditions, thus effectively realizing a light-diffusing function, thereby eliminating the need to additionally mount a diffusion film or a protection film. When a particle dispersion layer is further formed on the surface of a transparent substrate opposite the surface having the optical structure layer, damage due to friction to prism films or other sheets may be prevented during the layering of the prism films or transport, thus obviating the use of a plurality of optical films, consequently making it possible to economically manufacture a backlight unit with improved productivity.
    • 公开了具有作为背光单元的组成部分的光学结构的光学膜,例如棱镜膜或片。 光学膜包括具有多个光学结构的光学结构层,其表面形成为凹凸,并且在诸如棱镜的聚光光学结构的表面上形成不规则性以满足预定条件, 从而有效地实现光漫射功能,从而不需要另外安装扩散膜或保护膜。 当在与具有光学结构层的表面相对的透明基板的表面上进一步形成粒子分散层时,在棱镜膜或输送层的层叠期间可以防止由于与棱镜膜或其它片材的摩擦而引起的损伤,从而消除了 使用多个光学膜,因此能够以提高的生产率经济地制造背光单元。

    • Disclosed are a prism protection sheet, which is an optical sheet to be placed on a surface for forming prisms, corresponding to a light exit surface of a prism sheet, and a backlight unit assembly including the same. In the prism protection sheet, protection layers are formed on both surfaces of a substrate film using a composition solution containing light-diffusing particles and a binder, in which the protection layer in contact with the prisms has higher haze than that of the surface protection layer, thereby further increasing the light-scattering properties of the protection layer in contact with the prisms, leading to a higher contrast ratio and a widened view angle. The prism protection sheet is effectively used to construct an assembly of a backlight unit for LCDS, such as LCD monitors, notebook computers, TVs, PDAs, word processors, mobile phones, and games, requiring a wide view angle and a high contrast ratio while maintaining appropriate brightness, and the backlight unit assembly includes such a prism protection sheet.
    • 公开了一种棱镜保护片,其是与棱镜片的光出射面相对应的放置在用于形成棱镜的表面上的光学片,以及包括该光学片的背光源组件。 在棱镜保护片中,使用含有光扩散粒子和粘合剂的组合物溶液在基片膜的两面上形成保护层,其中与棱镜接触的保护层的雾度比表面保护层高 从而进一步增加与棱镜接触的保护层的光散射特性,导致更高的对比度和更宽的视角。 棱镜保护片有效地用于构成液晶显示器的背光单元组合,如LCD显示器,笔记本电脑,电视机,PDA,文字处理器,手机和游戏机,需要宽视角和高对比度,同时 保持适当的亮度,并且背光单元组件包括这种棱镜保护片。
