  • Publication number: 20020125232
    Abstract: The present invention disclose a laser cutter for cutting an object being cut such as a two glasses-attached panel for LCD using a laser beam. The laser cutter includes a laser unit for irradiating a laser beam with a specific wavelength along a marked cutting line of the object, a pre-scriber for forming a pre-cut groove at starting edge of the marked cutting line, and a cooling unit for cooling the cutting line which said laser beam has been irradiated.

  • Publication number: 20020027629
    Abstract: Disclosed is a liquid crystal display panel capable of being cut by a laser light. The liquid crystal display panel according to the present invention includes a substrate having a buffer layer between a conducting layer and an inner surface of the substrate, in which the buffer layer is disposed along a cutting line and spreads a crack and edges of the conducting layer is positioned in a region defined by the cutting line. Further, a method for manufacturing the liquid crystal display panel is disclosed, in which the liquid crystal display panel is machined by a laser cutter and a laser grinder.

  • Patent number: 6204909
    Abstract: A device and method for injecting liquid crystal material into a liquid crystal cell. The device includes a container for holding the liquid crystal material and a stand disposed in the container. The stand has an upper surface and at least one side having a plurality of furrows formed therein. The liquid crystal material is transported by capillary action to the upper surface where it is contacted with an injection hole of the cell. The method provides for removal of air from the liquid crystal material and injection of the liquid crystal material in an isotropic state.

  • Patent number: 6086443
    Abstract: Liquid crystal displays are manufactured by securing overlying first and second substrates with an intermediate sealant together such that they form a cell cavity with an injection opening. In one embodiment, a plurality of over-sized spacers are disposed intermediate the first and second substrates in the cell cavity. The first and second substrates are structurally secured by heat compressing the layers together with a pressure in the range of about 0.4-0.55 kg/cm.sup.2. A quantity of liquid crystal material is injected into the cell cavity through the injection opening to expand the substrate layers to a non-planar configuration. A second sealant is applied proximate to the injection opening and a second compressing step is used to facilitate the proper positioning of the second sealant into injection opening. The second compressing step employs a pressure about 0.1-1.0 kg/cm.sup.2 greater than the pressure in the first compressing step.
