  • Publication number: 20060232197
    Abstract: A structure to prevent lines of the device from being damaged or scratched by outside objects or to prevent short circuits from occurring is disclosed. The structure may be utilized in light emitting displays such as an organic electroluminescent panel. The structure includes a cell section, data lines, and scan lines. The cell section includes a plurality of pixels formed in luminescent area that are intersection areas of anode electrode layers and cathode electrode layers. The data lines each are connected to the anode electrode layers. The scan lines each are connected to cathode electrode layers. Here, insulating layers are formed to protect a subset of the data lines and/or a subset of the scan lines. Some of the lines are left uncovered so that inspection process may be carried out.

  • Publication number: 20060154602
    Abstract: A satellite signal reception system accurately receives a specific satellite signal without being affected by other set-top boxes when it is connected to a plurality of set-top boxes. The satellite signal reception system minimizes the distortion of a specific signal by set-top boxes connected to other output ports of a multi-switch without changing a circuit configuration of the multi-switch to another. The satellite signal reception apparatus comprises a multi-switch for switching a plurality of received satellite signals, and transmitting the switched satellite signals to a plurality of receivers; and an adapter which is connected between the multi-switch and a first receiver from among the receivers, and removes noise of a specific satellite signal to be received in the first receiver.
