  • Patent number: 7857468
    Abstract: The present invention provides an antiglare film, which includes a transparent resin layer, a plurality of transparent hollow particles and a plurality of transparent solid particles. The hollow particles and the solid particles are distributed in the transparent resin layer, while the hollow particles are partially exposed thereon. The refraction index of the hollow particles and the refraction index of the solid particles are different from the refraction index of the transparent resin layer. Applying both the solid particles and the hollow particles mixed together can lead the antiglare film to have an excellent antiglare property, a high contrast and a great clarity.

  • Publication number: 20100104851
    Abstract: A low reflective, anti-static and anti-fouling optical film, and a forming method thereof are disclosed. The forming method includes mixing an alkoxy silane, a fluoride-modified alkoxy silane, a conductive material and a pores formation agent to form a coating composition. Subsequently, the coating composition is solidified to form an optical film. The optical film includes a silicon oxide compound with fluorine element, the conductive material mixed therein, and a plurality of three-dimensional mesoporous. Therefore, the optical film of the present invention can simultaneously provide a low reflection, an anti-static effect and an anti-fouling effect.

  • Publication number: 20100068504
    Abstract: The present invention relates to a multiple-coating particle and an anti-glare film having the same. The anti-glare film includes a transparent resin and a plurality of multiple-coating particles. The multiple-coating particles are evenly distributed in the transparent resin. The multiple-coating particle is composed of at least two layers of the distinct transparent materials so as to scatter and refract light due to different refractive indexes and to provide anti-glaring effect.

  • Publication number: 20090128915
    Abstract: The present invention relates to an antiglare film, which comprises a cured transparent resin layer and a type of transparent hollow particles. The hollow particles are distributed in the transparent resin layer and partially exposed therefrom. The ratio of the inner diameter to the outer diameter of the hollow particle is within a range of 0.1 to 0.9, and the ratio of the outer diameter of the hollow particle to the thickness of the transparent resin layer is within a range of 0.1 5 to 1. The hollow particle and the transparent resin layer have different refractive indexes. The hollow particles are partially exposed from the surface of the transparent resin layer, leading the antiglare film to have excellent antiglare properties.

  • Publication number: 20080305302
    Abstract: A low reflection film and the forming method for making the same are disclosed. The low reflection film includes at least one siloxane resin and a plurality of silicon dioxide particles. The siloxane resin has at least two alkoxylates. The silicon dioxide particles are fixed by the siloxane resin and protrude from the surface of the siloxane resin. The method includes preparing a first solution by adding a first solvent to a mixture of a catalyst and a siloxane resin after sol-gel reaction, preparing a second solution by mixing the first solution with silicon dioxide particles, coating the second solution onto a surface, and performing a drying process to form the low reflection film.
