  • Publication number: 20100053527
    Abstract: A method for manufacturing a liquid crystal display (LCD) panel is provided. The method comprises the following steps. Firstly, an upper substrate and a lower substrate are provided. Next, a liquid crystal material is interposed between the upper and lower substrates. The liquid crystal material comprises at least one liquid crystal molecule and at least two photosensitive monomers, and the absorption peak of at least one photosensitive monomer is larger than 300 nm. Then, a voltage is applied between the upper substrate and the lower substrate, and a ultra-violet with a first wavelength is used for irradiation so as to allow most photosensitive monomers to be polymerized as polymer. Lastly, a ultra-violet with a second wavelength is used for irradiation, wherein the second wavelength is larger than the first wavelength so as to allow residual photosensitive monomers to be polymerized.

  • Publication number: 20090056853
    Abstract: A liquid crystal (LC) medium for polymerization alignment process includes at least a set of LC molecules, at least a set of reactive monomers, and at least one inhibitor at a concentration in a range of 0.01-1% wt of the reactive monomer. The inhibitor quenches polymerization of radicals of the reactive monomers, which is triggered by light or heat before the polymerization alignment process. Therefore influence on the reactive monomers before the polymerization alignment process is reduced and stability of the LC medium is improved.

  • Patent number: 7262858
    Abstract: An apparatus accesses and processes reflection images detected from microarray biochips with sidewalls. The apparatus uses a movable system to carry an optical module and a microtiter plate to achieve relative movement in different directions, so that pattern images of all wells in the microtiter plate can be retrieved during a single scanning process. Scanned image data are further compared with pre-defined patterns by a computer program for analysis.
