Abstract:
The present disclosure provides a display device having a touch sensor for securing improved touch-sensing performance. The display device having a touch sensor includes a shield electrode and a touch electrode, which are sequentially disposed on an encapsulation unit covering a light-emitting element. While a touch-driving signal is applied to the touch electrode, a load free driving signal of which at least one of the phase or the amplitude is the same as that of the touch-driving signal is supplied to the shield electrode, thereby securing improved touch-sensing performance.
