Abstract:
An optical film includes a supporting layer and a structured-surface layer having a plurality of prims juxtapositionally formed on the supporting layer, each prim including a lower prism element bonded with the supporting layer and at least one upper prism element integrally superimposed on the lower prism element to increase the prism height in order to pick up sideward refracted light to reduce light loss in order to enhance brightness of the optical film.
Abstract:
An optical film comprises: a transparent substrate; and a hybrid structured layer formed on the transparent substrate and including an upper structured portion composed of a plurality of light-concentrating units, such as prisms, formed on an upper portion of the hybrid structured layer for light concentrating, and a light scattering portion formed on a lower or bottom portion of the hybrid structured layer for light diffusing, thereby forming an optical film for simultaneously enhancing the brightness and light uniformity of the optical film and the optical devices made therefrom.
Abstract:
A light guide device comprises: a light guide plate made of transparent materials; and a light concentrating and diffusing structural portion integrally formed on an upper or outer portion of the light guide plate adjacent to a light-outgoing surface of the light guide plate in order to enhance the light concentrating effect and the light diffusing effect of the light guide plate.
Abstract:
An optical film includes a transparent supporting (or base) layer; a structured layer integrally formed on the supporting layer and having a plurality of light-concentrating units including prism units juxtapositionally formed on the supporting layer; and a plurality of tiny protrusions or recesses formed on (or in) the surfaces of the light-concentrating units to overcome the optical defects of the optical film and to synergetically enhance the optical properties of the optical film.
Abstract:
A multiple-layer optical film comprising: a transparent base layer, a diffusion layer formed on the base layer, and an upper prismatic layer formed on the diffusion layer having a plurality of root portions protruding downwardly from the upper prismatic layer to be respectively engaged with a plurality of recesses as recessed in the diffusion layer for firmly interlocking the upper prismatic layer with the diffusion layer. The diffusion layer includes nano or micron particles homogeneously dispersed in a resin matrix to obtain a composite layer having better light diffusibility; and the upper prismatic layer having nice light concentrating effect, thereby cooperatively synergetically forming a multiple-layer optical film having enhanced brightness, light uniformity, and dimensional stability.

Abstract:
An optical film comprises: a transparent supporting layer, and a plurality of multi-story prisms having multiple peaks formed thereon and juxtapositionally integrally formed on the supporting layer, each peak of the prism tapered or narrowed upwardly towards a light output direction for increasing a light concentrating effect of the prism in order to increase the brightness of the optical film.
Abstract:
A process for plating copper on particulate graphite comprises cleaning and drying the graphite particles; wetting the graphite particles with an aqueous solution of cupric sulfate and glacial acetic acid; dripping the graphite particles as wetted with a layer of the aqueous solution on a rotating metal (including zinc, aluminum and iron) disk to conduct a displacement reaction to plate copper, as displaced by the metal existing in situ on the metal disk, on each graphite particle; and washing the graphite particles as plated by copper with water and then drying the copper-plated graphite particles.
Abstract:
A precipitated film and the fabricating method thereof are disclosed. The precipitated film includes a supporting layer having columnar crystals, and a functional layer formed on the supporting layer and having granular crystals. The precipitated film is fabricated by phase-changing one of two aqueous solutions, which are able to react with each other to form a solid precipitate inherently, into solid-state and then reacting with the other aqueous solution to form the precipitated film by a precipitation reaction.
Abstract:
An optical film comprises a light-scattering substrate capable for diffusing light incoming through the substrate, and a prismatic layer having an array of a plurality of prisms and formed on the substrate for concentrating light when outgoing from the prisms, thereby obtaining an optical film for enhancing its brightness and light uniformity simultaneously.
