  • Publication number: 20130271705
    Abstract: The present disclosure provides color filter and a manufacturing method thereof, and a liquid crystal panel with the color filter. The color filter includes a substrate, a black matrix formed on the substrate, a number of spacers integrally formed with the black matrix; and a color filter with a thickness thereof being less than that of the black matrix. Color ink is disposed in the black matrix and is hardened to form the color filter layer. The black matrix and the spacers are integrally formed and made of the black film, which simplifies the manufacturing process of the color filter. Additionally, since the color filter layer is formed by the ink jet printing method, the height of the color filter is unlimited, which allows the black matrix and the spacers to be made of conventional material, and improves the yield rate of the color filter.

  • Patent number: 8398901
    Abstract: A new method to produce solid nanocrystalline cellulose (NCC) films containing patterns by differential heating of aqueous suspensions of NCC has been discovered. When acid-form NCC suspensions are dried by heating to temperatures above 50° C., darkening of the NCC can occur, while neutral forms of NCC can produce iridescent chiral nematic films by heating to temperatures up to 105° C. Placing materials of different thermal conductivity beneath the container containing an evaporating NCC suspension results in watermark-like patterns of different iridescent color imprinted within the film structure. Other colloidal rod-like particles can be employed in place of nanocrystalline cellulose (NCC), for example chitin or chitosan.

    Abstract: A method for manufacturing a polarizing lens that can form a uniform polarizing element on a curved surface of a lens base is provided. The polarizing lens is manufactured by the steps of: forming parallel grooves on a convex surface of a lens base by pressing the convex surface of the lens base onto a rotating surface of an elastic body and rotating the elastic body, the rotating surface having a length in a rotary shaft direction larger than a diameter of the lens base and holding abrasive grains; applying a polarizing dye on the convex surface of the lens base on which the parallel grooves have been formed; and fixing the polarizing dye to form a polarizing element on the convex surface of the lens base.
