  • Flat panel display
    Patent number: 8740447
    Abstract: In a flat panel display having integral frame structure, features of a metal frame and a plastic support, which support, position, and fix each component, are incorporated as an integral frame structure, such that no additional structure component is needed for the flat panel display to assemble the backlight module and the panel module. The frame structure is assembled to the bottom cover via screw that can reduce defectiveness of repetitive processing. A concave section at the bottom of the frame structure can contain a control circuit board for the panel cell such that the control circuit board can be rerouted downward to the bottom of the frame structure. The space required at the light source side of the flat panel display can be reduced, hence leading to the flat panel display with thin frame at the light source side.
