  • Publication number: 20040085739
    Abstract: A sliding-type portable wireless terminal that has a main body, and a sub body that longitudinally slides on the main body to open from and close into the main body. The sliding-type portable wireless terminal comprises a spring module that is fixed to the main body and includes torsion springs for supplying a sliding force in a direction of closing the sub body into the main body when the sub body is downwardly slid on the main body by a designated distance in the direction of closing the sub body into the main body, and supplying a sliding force in a direction of opening the sub body from the main body when the sub body is upwardly slid on the main body by the designated distance in the direction of opening the sub body from the main body. The sliding-type portable wireless terminal uses the torsion springs as means for sliding the sub body on the main body, thereby ensuring a smooth sliding motion of the sub body.

  • Patent number: 6716660
    Abstract: According to one aspect of the present invention, the thin film transistor array substrate basically includes a gate line assembly based on an Ag alloy. The Ag alloy comprises Ag and at least one of alloy elements and the alloy elements each bearing a low melting point. The gate line assembly comprises a gate electrode and a gate line. A data line assembly crosses over the gate line assembly while being insulated from the gate line assembly. The data line assembly comprises a source electrode, a drain electrode and a data line. A semiconductor layer contacts the source electrode and the drain electrode. The semiconductor layer forms a thin film transistor together with the gate electrode, the source electrode and the drain electrode. A pixel electrode is connected to the drain electrode.

  • Publication number: 20020151174
    Abstract: In a method for fabricating a thin film transistor array substrate, a glass substrate undergoes an oxygen plasma treatment. A silver or silver alloy-based conductive layer is deposited onto the substrate, and patterned to thereby form a gate line assembly proceeding in the horizontal direction. The gate line assembly includes gate lines, gate electrodes, and gate pads. Thereafter, a silicon nitride-based gate insulating layer is deposited onto the substrate, and a semiconductor layer and an ohmic contact layer are sequentially formed on the gate insulating layer. The semiconductor layer and the ohmic contact layer are HF-treated. A silver alloy-based conductive layer is deposited onto the substrate, and patterned to thereby form a data line assembly. The data line assembly includes data lines crossing over the gate lines, source electrodes, drain electrodes, and data pads.
