Abstract: A display apparatus is provided. In the display apparatus, a touch electrode may be disposed on the encapsulating element covering a light-emitting device, and a touch pad may be disposed on the outside of the encapsulating element. A touch line may be connected to the touch electrode. The touch line may be connected to the touch pad by a first touch link and a second touch link. The first touch link may include a first end connected to the second touch link, and a second end connected to the touch line. The first end of the first touch link may overlap with the encapsulating element. Thus, in the display apparatus, the reliability for a touch of a user or a tool may be improved.

Abstract: Disclosed is a display device having a reduced bezel area. The display device includes a plurality of touch lines electrically connected to a plurality of touch electrodes and display link lines electrically connected to a light-emitting element, the display link lines being disposed in a non-active area of a substrate, wherein a minimum of M touch lines (M being a natural number greater than 1 and less than N) is disposed with respect to a minimum of N display link lines (N being a natural number greater than 1), among the plurality of display link lines, in the non-active area. Consequently, a narrow bezel may be realized.

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.

Abstract: A display device having a touch sensor that enables the size of a bezel area to be reduced is disclosed. The display device is configured such that a display area is spatially divided into first and second touch areas, and first sensing-routing lines, connected to touch electrodes in the first touch area, and second sensing-routing lines, connected to touch electrodes in the second touch area, are not disposed in side and upper bezel areas but are alternately disposed in a lower bezel area. Consequently, it is possible to reduce the size of the side bezel area and the upper bezel area.

Abstract: An organic light-emitting display device having a touch sensor is discussed. The organic light-emitting display device can include a touch sensor formed in a single-layer structure and disposed on a touch insulating film overlapping 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 touch insulating film, thereby simplifying the structure thereof and reducing costs.

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.
