Abstract: A touch display device and a touch display panel. Touch lines and contact pads are disposed between touch electrodes, arranged in touch electrode lines in the touch display panel, and a driver circuit. A total of the area of each touch line and the area of the corresponding contact pad has a predetermined value. Differences in parasitic capacitance among the touch lines according to the positions of the touch electrodes are compensated for. It is possible to prevent the accuracy of sensing from being lowered by differences in parasitic capacitance among the touch electrodes disposed in different positions.

Abstract: The present embodiments generally relate to a display panel and a display device which may recognize touch. A display panel is provided in which a touch sensor and a touch line are disposed in an active area in which a part of an outer edge of the touch line is curved to correspond to a curved shape of the active area in the display panel so that the touch sensing is allowed in display panels having various shapes. Further, a touch display device is provided in which an open area is located between two adjacent touch lines disposed on the display panel so that touch sensing is allowed also in the display panel including an open area such as a hole or a notch.

Abstract: A touch display device and a touch display panel are provided. The touch display panel includes a bend area adjacent to the periphery of the touch display panel, and touch lines disposed in the bend area have zigzag shapes that extend at angles with respect to a bend axis about which the bend area is bent. A first dielectric layer includes a compensation pattern that is located in the bend area and includes an opening that extends in a direction parallel to the bend axis. A second dielectric layer protrudes into the opening of the compensation pattern in a depth direction. During bending of the bend area, this configuration disperses force applied to portions of the touch lines and the dielectric layers in the bend area. This can consequently prevent both cracking due to bending and moisture permeation due to cracks.
