  • Patent number: 11146780
    Abstract: An artificial window is provided. The artificial window includes a window having a frame, and a display device disposed at a back side of the window. The display device is used to display images. An image capturing device may be disposed on the window to obtain a viewer image of a viewer. Thus, a viewing direction of the viewer may be determined based on the viewer image, and the images being displayed on the display device may be changed based on the location of the viewer. The display device may be a curved display device, which is wider than the frame. Alternatively, the display device may be a flat display device, and a lenticular array formed by lenticular lenses is disposed between the window and the flat display device. Each of the lenticular lenses is focused on or close to a display surface of the flat display device.

  • Patent number: 10935853
    Abstract: A display cell structure includes a first substrate and a second substrate spaced apart from each other, and a polarizer layer disposed between the two substrates, forming a first cell gaps between the first substrate and the polarizer layer, and a second cell gap between the second substrate and the polarizer layer. A first display structure is disposed in the first cell gap, and a second display structure is disposed in the second cell gap. The first display structure includes a plurality of first signal lines, forming a first signal line pattern. The second display structure includes a plurality of second signal lines, forming a second signal line pattern. The second signal line is different from the first signal line pattern. The polarizer layer may be a wire grid polarizer layer.

  • Patent number: 10712616
    Abstract: A display cell structure includes a first liquid crystal display (LCD) panel and a second LCD panel. The first LCD panel includes a first polarizer layer, a second polarizer layer and a first liquid crystal layer, and liquid crystal molecules in the first liquid crystal layer have a first liquid crystal retardation. The second LCD panel includes a third polarizer layer, a fourth polarizer layer and a second liquid crystal layer, and liquid crystal molecules in the second liquid crystal layer have a second liquid crystal retardation. In some cases, the second liquid crystal retardation is different from the first liquid crystal retardation. In some cases, the third polarizer layer is a carbon nano-tube polarizer layer.

  • Patent number: 6862072
    Abstract: An ODF liquid crystal display panel is formed of a pair of mutually spaced-apart substrates. A liquid crystal layer is contained between the substrates. A first sealing member joins the substrates and defines an enclosed non-peripheral region in which the liquid crystal is contained. A second sealing member also joins the substrates. The second sealing member has a plurality of breaks, and is positioned inside the non-peripheral region defined by the first sealing member and divides the non-peripheral region into a display region and a buffer region in fluid communication with the display region. The gap between the substrates in the buffer region is larger than the gap between the substrates in the display region. The panel is formed by forming drops of liquid crystal in the display region and then joining the substrates using the sealing members. Excess liquid crystal flows through the breaks of the second sealing member into the buffer region.

  • 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.

  • 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.

  • 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.
