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.

Abstract: Disclosed is a touch display device capable of reducing deterioration in touch performance. The touch display device includes a plurality of first touch electrodes disposed in an active area of a substrate and a plurality of second touch electrodes disposed in the active area of the substrate, the plurality of second touch electrodes having different shapes from the plurality of first touch electrodes, wherein at least one of the plurality of second touch electrodes is formed by connecting at least two sub-electrodes having smaller areas than each of the first touch electrodes to each other. Consequently, the areas of the first and second touch electrodes are similar to each other, whereby it is possible to reduce touch performance deteriorated due to deviation in area between the touch electrodes.

Abstract: An organic light-emitting display device having a touch sensor is discussed. The organic light-emitting display device includes a touch sensor formed in a single-layer structure and disposed on an encapsulation unit disposed on a light-emitting element. First and second bridges and first and second touch electrodes included in the touch sensor having a single-layer structure are formed of the same material as each other in the same plane, e.g., on the uppermost layer of the encapsulation unit, thereby simplifying the structure thereof and reducing costs.

Abstract: A display apparatus is provided. The display apparatus includes touch electrodes on an encapsulating element. Each of the touch electrodes can be connected to a first touch line extending in a direction, and a second touch line extending in a direction opposite to the first touch line. Each of the touch electrodes can be connected to one of touch pads by one of the first touch lines. The second touch line can include an end on the encapsulating element. Thus, in the display apparatus, the reliability for the touch of a user or tool can be improved.
