  • Publication number: 20090237579
    Abstract: A liquid crystal display (LCD) panel employed in an LCD device includes an array substrate and an opposite substrate. The array substrate includes a pixel electrode formed in a pixel area including a first sub-pixel area and a second sub-pixel area. The opposite substrate is spaced apart from the array substrate to receive a liquid crystal layer. The opposite substrate includes a first common electrode formed in correspondence with the pixel area, and a second common electrode being floated in correspondence with the second sub-pixel area to form a coupling capacitor.

  • Publication number: 20080196047
    Abstract: An electronic device includes a central processing unit (“CPU”), first and second display panels, and first and second display panel drivers. The CPU provides an image signal and an input control signal. The first and second display panels respectively display images. The first and second display panel drivers drive the first and second display panels according to the image signal and the input control signal. The CPU includes an interface transmission unit outputting an interface signal to control the first and second display panel drivers. The first and second display panel drivers respectively include first and second interface receiving units receiving the interface signal from the interface transmission unit. The interface signal includes a display panel selection bit and a data bit.

  • Publication number: 20060110949
    Abstract: A receiving container for a display device includes a bottom plate, a sidewall and a grounding unit. The sidewall is extended from the bottom plate to define a receiving space. The grounding unit is integrally formed with the bottom plate. The grounding unit includes a grounding member that grounds a circuit board received in the receiving space. The circuit board includes a grounding electrode and the grounding member corresponds to the grounding electrode. The grounding member is formed on a rear surface of the bottom plate. The grounding member may include a protrusion or a projected portion having an elastic structure.
