  • Method of making accurate dimension alignment film for LCD
    Patent number: 6099786
    Abstract: A method of making accurate alignment layers in a liquid crystal display (LCD) cell is provided so that the LCD seal band can be placed as close to the pixel as possible. This method is implemented by ablating the apolyimide film on the glass substrates of the LCD cell to remove the alignment film where the sealing material is to be dispersed later. Thus, the sealing band can butt against the liquid crystal mixture without any clearance. In so doing, the display area is increased, and the reliability of the seal is improved.

  • LCD having trench formed on the substrate(s) to stop sealing material flowing to display areas
    Patent number: 6018380
    Abstract: A liquid crystal display device having a sealing material close to display area while maintaining a uniform liquid crystal cell gap is disclosed. The liquid crystal display comprises two transparent electrode substrates having a trench near the display area to stop the sealing material overflowing to display pixels. Thus, the effective display area of a liquid crystal display device is increased by dispensing a sealing material to a trench area at a predetermined position surrounding the display area. A spacer used in the sealing material is larger in size than that used in the display area to compensate the depth of the trench. After the liquid crystal is injected into the space surrounded by the substrates and a sealing material, a uniform liquid crystal cell gap over the entire display area is obtained.

  • Method of making counter electrode for liquid crystal displays
    Patent number: 5966194
    Abstract: The display area of a liquid crystal display cell is increased by placing conductive epoxy within the boundary which seals the liquid crystal to connect the top glass plate with the bottom glass plate, in contrast with the conventional method of making the electrical connection outside the display area. The conductive epoxy is dispensed in areas not occupied by the liquid crystal patterns. The conductive epoxy can be in the form of particles of spheres or rods serving as spacers for maintaining the gap dimension between the two glass plates. The conductive epoxy can also be integrated with the boundary sealing epoxy or fill a notch cut in the boundary sealing epoxy.
