    Abstract: A display device includes a flexible display panel, a sensing scan driver, and a sensing signal processor. The display panel includes a plurality of flexible touch input electrodes arranged in a first direction and a plurality of flexible touch output electrodes arranged in a second direction. The sensing scan driver supplies sensing input signals to the flexible touch input electrodes. The sensing signal processor receives sensing output signals through the flexible touch output electrodes. The display panel includes a plurality of touch sensing areas. One of the touch input electrodes and a pair of the touch output electrodes correspond to one of the touch sensing areas when the display panel stretches in the first direction by a predetermined first threshold value or more.

    Abstract: A touch screen panel includes a first touch electrode part, a second touch electrode part, a first touch router, a second touch router and plural third touch routers. The first touch electrode part includes plural first touch units. The second touch electrode part is substantially parallel to the first touch electrode part. The second touch electrode part includes plural second touch units. The first touch router is disposed adjacent to the first touch electrode part and is connected to one of an even-numbered first touch unit and an odd-numbered first touch unit of the first touch units. The second touch router is disposed adjacent to the first touch electrode part and is connected to the other of the even-numbered first touch unit and the odd-numbered first touch unit of the first touch units. The third touch routers are connected to each of the second touch units, respectively.
