Original Abstract Submitted
a touch display device can include a plurality of touch electrodes disposed on or in a display panel; and a touch driving circuit configured to drive the plurality of touch electrodes by outputting a touch driving signal having a first level period and a second level period. also, the touch driving circuit includes a current regulator configured to receive an input current from at least one of the plurality of touch electrodes during at least a partial period of the first level period and at least a partial period of the second level period of the touch driving signal, and scale down the input current to a first current and output the first current; and a converting integrator configured to output a sensing voltage based on the first current or a second current adjusted from the first current.
