  • Publication number: 20080311479
    Abstract: Disclosed is an electrode having a current collector coated with an electrode active material, wherein non-coated regions of the electrode and boundary regions of intermittently pattern-coated electrodes are coated with a porous active layer including a mixture of inorganic particles and a binder polymer. The electrode of the present invention may be useful to improve safety of a battery and also minimize reduction in the capacity of a battery by introducing the porous active layer onto non-coated regions of the electrode and/or boundary regions of the intermittently pattern-coated electrodes to prevent internal short circuit caused by the contact between both electrodes, wherein the boundary regions are coated with the electrode active material but vulnerable to the electrical short circuit.

  • Publication number: 20080292968
    Abstract: Disclosed is an organic/inorganic composite separator including: a porous substrate having pores; and a porous active layer containing a mixture of inorganic particles and a binder polymer with which at least one surface of the porous substrate is coated. The organic/inorganic composite separator of the present invention may be useful to enhance peeling and scratch resistances and improve a lamination characteristic by introducing a porous active layer onto a porous substrate having pores, the porous active layer having heterogeneity of morphology toward a thickness direction in which a content ratio of the binder polymer/inorganic particles present in a surface layer is higher than that of the binder polymer/inorganic particles present inside the surface layer. Accordingly, the stability and performances of a battery can be improved together since the detachment of inorganic particles from the porous active layer may be reduced during the assembly process of the electrochemical device.

  • Publication number: 20080068313
    Abstract: A display device includes a display panel provided with an electrode pad, a light source to emit light to the display panel, a mold frame to support the light source; a bottom chassis to accommodate the mold frame, a driving part to apply a driving signal to the display panel connected to the electrode pad, and a driving circuit part that controls the driving part. The driving circuit part includes a first driving circuit board connected to the driving part and on which circuit components are mounted toward the mold frame, and a second driving circuit board connected to the first driving circuit board. The display device further includes a flexible circuit board to connect the first driving circuit board and the second driving circuit board.

  • Publication number: 20070200589
    Abstract: A test apparatus for a Liquid Crystal Display (LCD) device receives a mode input signal representing whether the LCD device is driven in a normal voltage driving mode or a high voltage driving mode. The test apparatus transmits a voltage to the LCD device and transmits a control signal to a high voltage applying module, which turns on to transmit a high voltage to the LCD device or turns off according to a level of the control signal. The LCD device may remain coupled with the high voltage applying module while the LCD device operation is shifted between a high voltage driving mode and a normal voltage driving mode during a manufacturing process thereof, so manufacturing time for the LCD device may be reduced.
