  • Patent number: 7414680
    Abstract: A liquid crystal display apparatus includes a liquid crystal display panel, a driver printed circuit board, a backlight assembly and a receiving container. The driver printed circuit board is electrically connected to the liquid crystal display panel to provide the liquid crystal display panel with the image date. The backlight assembly is disposed under the liquid crystal display panel. The receiving container has front side and back side. The front side supports the backlight assembly. First and second protrusion portions are formed on a backside to support the driver printed circuit board, such that the driver printed circuit board is spaced apart from the backside of the receiving container. Thus, a work for lifting up the data PCB to insert the digitizer into between the data PCB and the receiving container is not required, so that productivity is enhanced.
