  • Publication number: 20070002270
    Abstract: A method that uses at least one hydrogen ion beam for alignment of liquid crystal molecules is proposed in the present invention. The method of the present invention is proposed to resolve the problems of physical destruction and surface deterioration of the alignment films caused by the conventional method using argon ions beams. The method of the present invention directly uses at least one hydrogen ion beam to impact the alignment film. Hence, the physical destruction of the alignment film is reduced. In addition, via the reaction between hydrogen ions and the alignment films, the quality of the alignment film is improved.

  • Patent number: 7060420
    Abstract: A fabrication method for a liquid crystal display. A pair of substrates is provided. An alignment layer is formed on the respective substrates. An energy beam is irradiated on a predetermined area of at least one of the alignment layers. The alignment layer is rubbed to form a first pretilt-angle area in the predetermined area exposed to the energy beam, and a second pretilt-angle area not exposed to the energy beam. The pair of substrates are bonded with a preset gap therebetween, and a liquid crystal layer is inserted between the substrates. The liquid crystals corresponding to the first pretilt angle area have a first pretilt angle of ?1, while those corresponding to the second pretilt angle area have a second pretilt angle of ?2.

  • Publication number: 20050064116
    Abstract: A polymer gel display, fabrication method and operating structure thereof. Display is enabled by utilizing the flexing characteristic of a polymer-gel sheet. A pair of substrates is separated by a predetermined gap, and a polymer-gel sheet of a first color disposed therebetween, having two ends fixed, a center area flexible and contacting no more than one of the substrates. A fluid layer of a second color is disposed between the substrates, displaying its color via the substrate not contacting the polymer-gel sheet. An external electric field is applied to the polymer-gel sheet, flexing the polymer-gel sheet toward the substrate until making contact and the first color of the polymer-gel sheet is displayed via the substrate.

  • Publication number: 20050045478
    Abstract: a manufacturing method for an electrophoretic display applying optical polymer material is provided. The main characteristic is that the charged pigment particles are confined with optical polymer material so as to achieve electrophoretic display. In the manufacturing process, a first layer of optical polymer material is coated on an auxiliary substrate having a buffer layer for performing an optical polymerization manufacturing process. After the polymerization, on the first layer of the optical polymer material layer, the manufacturing process required by the electrophoretic display is further performed. After a second layer of optical polymer material is coated on a substrate required by the electrophoretic display having a plurality of electrode patterns, by using a mask exposure, the optical polymer material is solidified to form a polymer wall, or a molding method is applied with ultraviolet irradiation for solidifying the optical polymer material so as to form the polymer wall.
