  • Patent number: 8184254
    Abstract: A liquid crystal display and a method of fabricating the same is capable of strengthening adhesion between a sealant and a lower plate in a panel with a high aperture ratio to which an organic protective film is applied. The organic protective film and a gate insulating film are patterned in such a manner that the sealant comes into contact with a substrate directly. Accordingly, the organic protective film or the gate insulating film at the area coated with the sealant is partially or entirely removed to directly contact the sealant with the gate insulating film or the lower glass, thereby strengthening the adhesion between the sealant and the lower plate.

  • Patent number: 7151586
    Abstract: A liquid crystal display device is provided wherein an adhesive force between a seal and a lower plate is improved upon bonding of an upper plate to the lower plate. In high aperture liquid crystal display panels, organic protective films are used to reduce dielectric constants. However, the seal, used when bonding the upper and lower plates of the liquid crystal panel, generally do not adhere well to organic materials. In this invention, holes are generated in the organic protective film so that the seal bonds with inorganic materials such as the lower glass plate or the gate insulating film.

  • Patent number: 6535244
    Abstract: An image stabilizing apparatus for correcting motion of an image recording apparatus by using a bit-plane matching technique, and an image stabilizing method thereof. In the image stabilizing apparatus, a field memory stores input digital image information. A motion detecting circuit calculates an amount of movement of input image information between two screens by using bit-plane matching technique and outputs a motion vector of the image recording apparatus. A motion correcting circuit corrects the motion of the image recording apparatus by moving image information stored in the field memory in an opposite direction to the direction of the motion vector.

  • Patent number: 6122319
    Abstract: An apparatus and method for detecting a motion vector by converting an input image into gradient pattern information and comparing gradient pattern information in a motion detection area of a current field with representative pattern information of a previous field. A gradient pattern converter converts a gray level of each pixel in a motion detection area in an input image into a gradient bit pattern by comparing differences between the gray level of the pixel and gray levels of its adjacent pixels with an arbitrary threshold value. A motion vector detector forms a search area sequentially in the motion detection area, compares a gradient bit pattern of the search area with a representative bit pattern of a previous image to calculate and accumulate correlation values, and determines a difference of coordinates of a search area which results in a maximum correlation value and coordinates of the representative bit pattern as a motion vector.
