Abstract
There are provided a touch display device, a touch driving circuit, and a touch sensing method. More specifically, a touch display device includes a touch screen panel including a plurality of touch electrodes and a touch driving circuit configured to output a touch driving signal to at least a portion of the plurality of touch electrodes for sensing a touch. Upon detection of an event in which at least one first area of the touch screen panel is set as a touch sensing area and at least one second area of the touch screen panel is set as a non-touch sensing area, the touch driving circuit is configured to output the touch driving signal to one or more of the plurality of touch electrodes that correspond to the at least one first area of the touch screen panel.
