Classification: CPC G | IPC G

Claim 0:
1. A touch display device, comprising:
a plurality of touch electrodes; and
an overcurrent detection circuit configured to detect a current flowing through at least one touch pad electrically connected with at least one touch electrode among the plurality of touch electrodes;
a touch driving circuit outputting a touch driving signal; and
a level shifter including a plurality of output pins, the level shifter generating a voltage level-controlled touch driving signal by controlling a voltage level of the touch driving signal, and outputting the voltage level-controlled touch driving signal to the at least one touch pad,
wherein the overcurrent detection circuit is electrically connected to at least one output pin among the plurality of output pins,
wherein the level shifter further includes a feedback signal output pin that outputs a feedback signal which has a different value when an overcurrent flows through any one output pin among the plurality of output pins than when the overcurrent does not flow through the any one output pin.
