More Information
Summary:The disclosure is related to a touch display device, a shield electrode separated from a common electrode of a light-emitting element can be disposed on an area overlapping a touch electrode under an encapsulation layer, and a shield driving signal corresponding to a signal supplied to the touch electrode can be supplied to the shield electrode. Thus, the shield electrode prevents or at least reduces formation of a parasitic capacitance between an electrode or a signal line for a display driving and the touch electrode, and a touch detection performance can be improved by implementing a noise blocking function by the shield electrode.
