  • Patent number: 9336702
    Abstract: A display apparatus includes an image data comparator which receives first, second and third color image data, extracts first, second and third image data from the first, second and third color image date by comparing gray scale values of the first, second and third color image date such that each of grayscale values of the second and third image data is greater than or equal to a gray scale value of the first image data, and compares the gray scale value of the first image data with a predetermined gray scale value, a driving circuit which generates a gray scale signal based on a result of the comparison and generates first and second color signals based on the first, second or third image data, and a pixel including a first sub-pixel which receives the gray scale signal, second and third sub-pixels which receive the first and second color signals, respectively.

  • Patent number: 8446662
    Abstract: A method of manufacturing is disclosed for an electrophoretic display apparatus that includes an array substrate and an electrophoretic film laminated to the array substrate. A thermally activated adhesive is used to adhesively attach the electrophoretic film to the array substrate. The electrophoretic film is first aligned to and flattened against the array substrate and then a substantially stronger than original adhesion property of the adhesive is activated by annealing at a high temperature that is substantially greater than room temperature. Rework prior to annealing is therefore possible when alignment errors occur between the electrophoretic film and the array substrate.

  • Patent number: 8400438
    Abstract: A display apparatus includes a display panel on which a pad part is formed, a driving chip including bumps making contact with the pad part, and a non-conductive adhesive film disposed between the display panel and the driving chip attaching the driving chip to the pad part. Each of the bumps includes a step-difference portion including a non-conductive elastic polymer and a bump line formed on the step-difference portion. The bump line is provided with a fine pattern through which a portion of the step-difference portion is exposed, and the bump line makes contact with the pad part. Accordingly, the reliability of the electrical connection between the driving chip and the display panel may be increased.

  • Patent number: 8293564
    Abstract: A thin film transistor substrate includes a color filter layer and a gate line. The color filter layer has a reverse taper shape, which is used to pattern the gate line without a separate mask. Thus, the total number of masks used to manufacture the thin film transistor substrate can be reduced, thereby reducing the manufacturing cost and improving the productivity.

  • Publication number: 20110175856
    Abstract: An electrophoretic display panel includes a first member, a second member, an electrophoretic layer and an outer member. The first member includes a first substrate and a pixel electrode formed on the first substrate. The first substrate has a display area and a dummy area disposed outside of the display area. The second member includes a second substrate facing the first substrate and a common electrode formed on a first surface of the second substrate. The electrophoretic layer is disposed between the first member and the second member and displays an image by an electric field generated between the pixel electrode and the common electrode. The outer member covers the dummy area and blocks light, so that display quality is improved.
