  • Patent number: 8816483
    Abstract: A method for fixing a semiconductor chip on a circuit board is provided, which includes following steps. The circuit board is provided, which sequentially includes a substrate having a chip connecting portion, at least one metal wire and an insulating layer. An organic insulating material is formed on the insulating layer of the outside edge of the chip connecting portion. An anisotropic conductive film (ACF) is then formed to cover the chip connecting portion and a portion of the organic insulating material. Finally, a semiconductor chip is hot-pressed on the ACF. The organic insulating material formed on the insulating layer is used to prevent the metal wires beneath the insulating layer from occurring of corrosion. A semiconductor chip package structure is also provided.

  • Patent number: 8766957
    Abstract: A display device and a repairing method for the same are disclosed. The display device includes a substrate, a pixel array, at least one gate driver unit, at least one source driver unit, a first repair line, a second repair line, a first dummy line, and a second dummy line. The first repair line is disposed between the pixel array and the source driver unit. The second repair line is disposed opposite to the first repair line on the pixel array. The first dummy line and the second dummy line are respectively disposed at two sides of the pixel array and crossing the gate lines, the first repair line, and the second repair line. A signal transmission is not required to go around the outmost periphery of the gate driver unit in a repairing process. As a result, the signal attenuation can be decreased effectively.

  • Patent number: 8325288
    Abstract: A display panel having a repair structure utilizes floating repair lines integrated into the display panel. Each of the floating repair lines bridges across each of any two adjacent pixels so as to be used for the repair of open lines on scan lines, data lines and common lines in the display panel as required. The display panel of the present invention having a repair structure integrates each of the floating repair lines between each of any two adjacent pixels so as to form new substitutional signal transmission routes of various types of open lines. The substitutional signal transmission route is able to reduce the resistive-capacitive delay of the repaired display panel and the impedance of repaired lines, and avoid signal decay and distortion.
