Xiaojia Wang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Microcup compositions having improved flexure resistance and release properties
    Publication number: 20030175481
    Abstract: This invention relates to a novel composition suitable for use in the manufacture of electrophoretic display cells. The mechanical properties of the cells are significantly improved with this composition in which a rubber material is incorporated.
    Type: Application

    Inventors: Xianhai Chen, Mary B. Chan-Park, Xiaojia Wang, Rong-Chang Liang
  • Process for roll-to-roll manufacture of a display by synchronized photolithographic exposure on a substrate web
    Publication number: 20030152849
    Abstract: This invention relates to an electrophoretic display or a liquid crystal display and novel processes for its manufacture. The electrophoretic display (EPD) of the present invention comprises microcups of well-defined shape, size and aspect ratio and the microcups are filled with charged pigment particles dispersed in an optically contrasting dielectric solvent. The liquid crystal display (LCD) of this invention comprises well-defined microcups filled with at least a liquid crystal composition having its ordinary refractive index matched to that of the isotropic cup material. A novel roll-to-roll process and apparatus of the invention permits the display manufacture to be carried out continuously by a synchronized photo-lithographic process.
