  • Patent number: 8199517
    Abstract: Provided are a flexible printed circuit board (PCB), which can contribute to the reduction of damage to wiring layers and wiring defects regardless of a decrease in the width of wiring layers and can thus contribute to the miniaturization of various products, a method of fabricating the flexible PCB, and a display device having the flexible PCB. The flexible PCB includes a base film, one or more first pad patterns formed on the base film, one or more second pad patterns formed on the base film and connected to the one or more first pad patterns, a cover film formed on the one or more first pad patterns and the base film and exposing the one or more second patterns, and a plurality of expanded portions corresponding to the boundaries between the one or more first pad patterns and the one or more second pad patterns and having a greater width than the one or more first pad patterns and the one or more second pad patterns.

  • Publication number: 20070182683
    Abstract: In an apparatus for generating a gamma voltage to enhance a display quality and a display device having the apparatus, the apparatus of the display device having a display panel and a plurality of driving chips mounted on the display panel, each of the driving chips having a data driving part for outputting a data signal, includes a plurality of gamma resistors, output terminals and a stabilizing circuit part. The gamma resistors are serially coupled between a power terminal and a ground terminal. The output terminals are directly connected to a data driving part for outputting distributed gamma voltages. The stabilizing circuit part is electrically connected to the output terminals and is mounted on a printed circuit board disposed on a side of the display panel for stabilizing the gamma voltages. Therefore, an output deviation among the driving chips is removed, so that the display quality can be enhanced.
