  • Publication number: 20160098134
    Abstract: A touch display device comprises a controller to generate a touch sync signal for controlling timing of a touch sensing period and a display period. A touch panel has a plurality of touch electrodes in a display area of the touch display device. The touch panel generates touch sensing signals indicating whether or not a touch occurs during the touch sensing period. A gate driver supplies gate pulses to gate lines of the touch panel during the display period and supplies a gate line auxiliary drive signal from the first transfer line onto the gate lines during the touch sensing period that mimics the touch drive signal. One or more auxiliary lines supply a supplemental auxiliary drive signal during the touch sensing period that mimics the touch drive signal.

  • Publication number: 20150343903
    Abstract: Disclosed are a safety system of a fuel cell vehicle and a control method for the safety system. A safety system of a fuel cell vehicle using a fuel cell and a high voltage battery as a power source may include: a power switch disposed on a power wire connecting the power source and a power load to each other; an insulation resistance measuring device measuring an insulation resistance between the power wire and a chassis; and a controller controlling an operation of the power switch based on a measured insulation resistance measured by the insulation resistance measuring device. When the measured insulation resistance is equal to or less than a reference resistance, the controller enters a safe mode and the power switch is turned off to thereby block power supplied to the power load.
