A touch electrode line is divided in the active area in a structure in which touch routing lines are coupled to both sides of the touch electrode line, so that resistance and parasitic capacitance may be reduced due to the touch electrode line and the touch routing line. In addition, a dummy pattern is disposed between the divided touch electrode lines, so that it is possible to easily implement an arrangement structure of the touch electrode line with improved touch sensing performance by preventing a short circuit defect between the divided touch electrode lines due to static electricity.

Touch display device

A touch display device can include at least one transistor on a substrate; an organic light-emitting diode on the at least one transistor; an encapsulation layer on the organic light-emitting diode; a touch buffer on the encapsulation layer; touch electrodes comprising at least one X-touch electrode and at least one Y-touch electrode on the touch buffer; a touch sensing circuit electrically connected with the touch electrodes; a black matrix on the touch electrodes; and color filters on the black matrix. Also, the touch display device can include at least one dummy metal disposed adjacent the at least one X-touch electrode and disconnected from the at least one X-touch electrode; in which each of the at least one X-touch electrode and the at least one Y-touch electrode has a body portion and a plurality of wing portions connected to the body portion.

A touch display device includes a touch planarization film. The touch planarization film may be disposed on an inclined portion of an encapsulation layer in a non-active area of a display panel, and a touch routing line may be disposed on the planarized area of the touch planarization film, so that it is possible to reduce parasitic capacitance between the touch routing line and a display signal line located under the encapsulation layer without increasing dimensions of the non-active area. Therefore, it is possible to easily adjust a width of the touch routing line and reduce the parasitic capacitance deviation between the touch routing lines, thereby improving the performance of the touch sensing.

Embodiments of the present disclosure provide a touch display device. A body portion and a wing portion of a touch electrode are formed by cutting the electrode metal along the direction in which the electrode metal is arranged. The body portion, the wing portion and a dummy metal located therein are irregularly formed, so that it is possible to improve the performance of touch sensing and improve the visibility of the electrode metal. In addition, in the case of a large-area touch display device, by dividing the touch electrode line and forming a cutting pattern corresponding to the divided boundary of the touch electrode line inside the touch electrode line, it is possible to prevent the divided boundary of the touch electrode line from being recognized and reduce a load on the touch electrode line, thereby improving the performance of touch sensing.

A display device includes a flexible display panel, an ultrasonic fingerprint sensor which is disposed below a rear surface of an active area of the flexible display panel and has a first thickness and a first width, a cushion structure which is disposed below the rear surface of the flexible display panel, surrounds the periphery of the ultrasonic fingerprint sensor, and has a second thickness larger than the first thickness, and a circuit board which is electrically connected to the ultrasonic fingerprint sensor and has a second width larger than the first width.
