  • Patent number: 7974103
    Abstract: A signal transfer member for a liquid crystal display (LCD) apparatus includes a power line for receiving power from an external source and for driving a semiconductor chip disposed on the transfer member or the display apparatus. The power line is bent so as to incorporate a serpentine structure, which enables the length of the power line to be easily adjusted and results in the line being longer than a power line formed with a relatively straight structure. Accordingly, the length of the power line can be adjusted to take into account the respective impedances of the chip and the external source so as to suppress electromagnetic waves in the power line. This prevents the creation of noise, distortion of signals, damage to the semiconductor chip, and disconnection of the input interconnection thereof that are caused by the electromagnetic waves, so that product yields are thereby improved.

  • Patent number: 7953052
    Abstract: A handoff method in a communication system where BSs providing different radio access interfaces to an MS are connected to an IP-based network through routers. A handoff from a first BS to a second BS is decided for an MS that receives IP service data from the first BS and an L2 connection is established between the MS and the second BS. During the L2 connection establishment, movement of the MS in the IP network is detected. Handoff negotiations are conducted between the first and second BSs by IP signaling. If the handoff is available according to the negotiations, mobility management control is performed considering movement of the MS. The IP service data is transmitted to the MS in a network path reset to the second BS by the mobility management control and an L2 connection is released between the MS and the first BS.

  • Patent number: 7943931
    Abstract: A substrate includes an array area and a data pad area adjacent to the array area. A gate line, a data line and a switching device are formed in the array area of the substrate. A data pad extending from an end of the data line and a supporter provided between the substrate and the data pad are provided in a data pad area to allow the data pad to be placed at a higher position than a passivation layer. Thus, a contact resistance occurring between an anisotropic conductive film and a bump and a contact resistance occurring between the anisotropic conductive film and the data pad are reduced.

  • Publication number: 20100265435
    Abstract: In a display apparatus according to an embodiment, a variable diffuser film is disposed between a backlight unit generating light and a display panel displaying an image. The variable diffuser film transmits or scatters the light from the backlight unit in response to an electrical signal to control a viewing angle. The variable diffuser film is disposed between the first and second transparent layers and includes a polymer layer in which liquid crystal molecules transmitting or scattering the light according to the electrical signal are dispersed. The polymer layer has a thickness of about 3 micrometers to about 15 micrometers, and the liquid crystal molecules have an anisotropic refractive index (?n) of about 0.15 to about 0.25. In one aspect, the display apparatus may automatically switch a narrow viewing angle mode and a wide viewing angle mode, thereby reducing power consumption necessary to switch the narrow and wide viewing angle modes.
