  • Noise-reduced mobile communication apparatus
    Patent number: 7505072
    Abstract: A mobile communication apparatus that comprises an image pickup device (or camera module) comprising a lens driver (or AF motor), a display device (comprising a main display and a sub-display), and a display driver (comprising liquid crystal drivers) are disposed on a circuit board. The display driver and the image pickup device are disposed on the opposite sides, respectively, of the display device. Thus, the display driver and the lens driver of the image pickup device are distant from each other, thereby avoiding mutual interference by electromagnetic waves that may be produced by them.
