  • Publication number: 20090103019
    Abstract: A color filter substrate having a substrate, a black matrix layer, a first filter layer and a second filter layer is provided. The black matrix layer is disposed on the substrate, and multiple pixel areas is defined on the substrate by the black matrix layer. Each pixel area includes a first sub-pixel area and a second sub-pixel area. The first and second filter layer are disposed in the pixel area, and the second filter layer covers the first filter layer. A refractive index of the second filter layer is greater than that of the first filter layer, such that light emitting direction of the first sub-pixel area is different from that of the second sub-pixel area. Besides, a fabricating method of the color filter substrate and an LCD panel with the color filter substrate are provided. The LCD panel with 3D image display or dual-view function can be easily manufactured.

  • Publication number: 20080145613
    Abstract: A method is provided for making extensible artificial leather. In the method, a substrate is supported on in-extensible woven cloth and locating the substrate firmly on a coating machine. Foamy highly solid-containing water-based polyurethane resin is coated on the substrate for forming a middle layer with tiny open cells. The middle layer is dried and the woven cloth is removed from the substrate. A superficial layer of polyurethane is attached to the middle layer in a dry process so that the extensible artificial leather is made with excellent strength against peeling, abrasion and dissolution.

  • Publication number: 20080095945
    Abstract: A method for making a macromolecular laminate is disclosed. Firstly, a high solid-content polyurethane resin is prepared. The high solid-content polyurethane resin has a solid content higher than 80% by weight and a viscosity from 20000 to 60000 cps/30° C. The high solid-content polyurethane resin is liquid at the room temperature. The high solid-content polyurethane resin is mixed with additives to form a first type of polyurethane resin compound with a solid content higher than 50% by weight and a viscosity from 20000 to 60000 cps/30° C. The first type of polyurethane resin compound is liquid at room temperature and has a pot life of at least three hours at room temperature. The first type of polyurethane resin compound is coated on a releasing paper to make a main layer. Then, the releasing paper is removed from the main layer to make a laminate.

  • Publication number: 20080075938
    Abstract: A macromolecular laminate includes a main layer made of a first type of polyurethane resin compound that is liquid at room temperature. The first type of polyurethane resin compound is made through mixing polyurethane resin with solid content higher than 50% by weight with additives. An auxiliary layer may be formed on the main layer and made of a second type of polyurethane resin compound different from the first type of polyurethane resin compound.

  • Publication number: 20050181190
    Abstract: A method for making a macromolecular laminate is disclosed. Firstly, polyurethane resin with solid content higher than 50% is mixed with additives in order to form polyurethane resin compound that is liquid at the normal temperature. Then, the polyurethane resin compound is coated on releasing paper and dried. Then, the releasing paper is removed in order to make a substrate. Then, the substrate is put in a physical vapor deposition system in which metal is used as a target. Finally, the metal is sputtered to the substrate in order to form a metallic film, thus making a macromolecular laminate.
