  • Publication number: 20090202838
    Abstract: A self-assembling optical film structure and a method of manufacturing the same are provided herein. The manufacturing method includes spreading a coating liquid formed with blending an acrylic resin, a fluothane-grafted acrylic resin, and a siloxane-grafted acrylic resin, or the liquid can be formed with an acrylic resin containing a fluorine compound or a silicon compound, so as to form a self-assembling optical film structure on a coated film surface, thus significantly reducing the cost. As a result, random and irregular array is generated during spreading the coating liquid, so we can effectively reduce the generation of optical interference due to the regular structure, and the product thereby has better brightness enhancement property and can be composed of relatively less layers of optical films.

  • Patent number: 7023520
    Abstract: A method and a system for fabricating a liquid crystal film are proposed. First of all, mechanical rubbing is performed on a surface of a plastic substrate. The surface of the substrate is applied with dispersed liquid crystal material over the substrate. At least one cycle annealing treatment is performed to orientate liquid crystal molecules in a fixed direction, so that a liquid crystal solid film is formed by curing the liquid crystal molecules. In addition, a method for fabricating a brightening film using the liquid crystal solid film is also proposed. The method is applicable to a continuous process for forming a cholesteric liquid crystal film on the plastic substrate, and fabricating a reflective cholesteric liquid crystal brightening film using the cholesteric liquid crystal film, so that light transmittivity and intensity are effectively increased under the same backlight source.
