  • Patent number: 8493680
    Abstract: An electronic device includes a power supply line connected between a DC power supply and an integrated circuit, and a first electronic element and a second electronic element serially connected between the power supply line and ground. The second electronic element is open when the first electronic element is short-circuited due to an overvoltage induced in the power supply line. When the overvoltage exceeds a breakdown voltage of the first electronic element, the first electronic element supplies an overcurrent induced in the power supply line to the second electronic element.
    Type: Grant

  • Publication number: 20070081118
    Abstract: Disclosed is an LCD device and a method for fabricating the same, capable of preventing defects derived from a defective UV-curing of a sealant while employing one-drop fill technology. The LCD device includes an array substrate having a metal signal line, a thin film transistor and a pixel electrode, a color filter substrate having a light shielding pattern and a color filter, a sealant interposed between the substrates and cured in order to fixedly combine the array substrate with the color filter substrate, and a liquid crystal layer interposed between the array substrate and the color filter substrate through one-drop fill technology. The shielding pattern is made of resin including a transparent heat-sensitive pigment, in which a color of the heat-sensitive pigment is changed to black through a heat-sensitive reaction and UV light passes through the heat-sensitive pigment.
