Zusammenfassung: | A touch driving circuit and a touch display device are disclosed. A group sensing control switch connected between lines connected to sensing units included in a touch driving circuit is disposed, thereby providing a structure in which one sensing unit can drive a touch electrode driven by another sensing unit. One sensing unit simultaneously drives two or more touch electrodes according to an operation state of a group sensing control switch to perform touch sensing, thereby providing a touch driving circuit and a touch display device capable of maintaining the resolution of touch sensing and improving touch sensitivity according to a driving environment. |
