Sealing Of Liquid Crystal Patents (Class 349/190)
  • Patent number: 8908142
    Abstract: A manufacturing method of a liquid crystal panel, including: manufacturing a first substrate and a second substrate; mixing sealant with alloy particles having low melting points, coating the mixture on the first substrate, and dropping liquid crystals on the first substrate; and bonding the first substrate and the second substrate, heating the two bonded substrates, and then cooling the substrates. Therefore, the manufacturing method can prevent the present golden balls from piercing the common electrodes and further prevent the short circuit of the circuit on the substrate, which improves the yield rate of the liquid crystal panel. Additionally, since the alloy particles are small sized, after the separate alloy particles melt, contacting points between the alloy particles and the common electrodes are increased.

    Abstract: Apparatus and methods are provided for resizing an electronic display that includes front and back plates, a perimeter seal spacing apart the plates and defining an enclosed cell area between the plates that includes an original display image area, image-generating medium sealed in the enclosed cell area, and electrical circuits on inner surfaces of the plates extending throughout the original display image area. For example, a cut line may be identified that intersects across the original display image area of the display. A laser may be directed adjacent the cut line to heat and/or separate leads of the electrical circuits adjacent the cut line. The display may be cut adjacent the cut line, e.g., before or after separating leads along the cut line, resulting in a target display portion with an exposed edge, and an excess display portion, and then the exposed edge may be sealed.

    Abstract: In a liquid crystal device, a shoulder portion configured to increase the distance between a element-substrate-side substrate body and a opposed-substrate-side substrate body is provided on the opposed-substrate-side substrate body in an area overlapped with a sealing material including a gap material. Therefore, in an area inside the sealing material, the gap between the element substrate and the opposed substrate is smaller than the gap therebetween in the area overlapped with the sealing material. Therefore, the layer thickness of the liquid crystal layer can be reduced without reducing the size of the gap material.

  • Patent number: 8864541
    Abstract: Pre-manufactured electronic displays and, in particular, liquid crystal flat-panel displays, may be cut to a new size and resealed while preserving their originally-manufactured properties. A display may be cut, and the exposed edge of a target portion may be sealed, e.g., to preserve the integrity of the target portion of the display. It may be desirable to cause a sealant to go in between the plates of the panel, e.g., to achieve improved yield, chemical isolation, dimensional integrity, and/or strength of the seal. Apparatus and methods are disclosed where the sealant is injected or otherwise forced into the region between the plates adjacent the exposed edge. This sealing process may achieve more sealant surface contact area inside the panel in between the plates, e.g., to achieve better bonding strength, chemical isolation, and/or improved yield.

  • Patent number: 8665414
    Abstract: Thermochromic liquid crystal filters are fabricated by providing two polarizers oriented at offset polarity with respect to each other; providing alignment structures adjacent the inner surfaces of the polarizers; placing a plurality of spacers between the polarizers; and filling a space created by the spacers with a thermotropic liquid crystal that acts as a depolarizer in a nematic state. The filter acts as a wave block when the liquid crystal is in an isotropic state. Alternatively, the filters can be created by encapsulating a thermochromic liquid crystal with a polymer material to form a flexible film and orienting the thermochromic liquid crystal in the polymer material to create a structure that functions as a thermochromic optical filter. Such filters can control the flow of light and radiant heat through selective reflection, transmission, absorption, and/or re-emission. The filters have particular application in passive or active light-regulating and temperature-regulating films and materials.

  • Patent number: 8665411
    Abstract: Techniques are provided for unifying steps of sealing material so that the yield and the reliability of a liquid-crystal display device become high. A starting film of scanning lines is patterned so that prismatic dummy wirings 301 for the first layer which are not electrically connected are formed in regions R1 and R2, and wirings 302 extending from the pixel section are formed in a region R3, and wirings 303 having connection end portions 303a are formed in a region R4. After an interlayer insulation film is formed, the starting film of the signal lines is patterned so that the dummy wirings 304 for the second layer are formed to embed the gaps between the wirings 301 to 303, and also the wirings 305 and the wirings 303 which extend from the pixel portion are connected to each other. This permits unification of the cross-sectional structure of the sealing material formation region.

    Abstract: Apparatus and methods for resizing COTS AMLCDs or other electronic displays, as well as resized displays made using these apparatus and methods, are provided. The electronic display includes a front plate, a back plate, a perimeter seal spacing the front and back plates apart, and image-generating medium contained in an area between the front and back plates. A target portion of the display may be identified and separated from an excess portion of the display, e.g., by cutting and breaking the plates of the display, thereby creating an exposed edge along the target portion. The plates of the target portion are pressed towards one another, e.g., to stabilize or compress the target portion. An adhesive is applied to the exposed edge, and the pressure is released to draw the adhesive between the plates along the exposed edge.
