Abstract: A gate driver includes a plurality of shift registers and a plurality of connection controllers. The shift registers are connected to a plurality of gate lines of a stretchable display panel, respectively. The shift registers are grouped into a plurality of shift register groups. N adjacent shift registers constitute each of the shift register groups, where N is an integer greater than or equal to 2. The connection controllers change a connection structure of the N adjacent shift registers included in the each of the shift register groups according to whether the stretchable display panel is stretched.

Abstract: A display device may include a first touch sensing member on a top surface of a display panel, a second touch sensing member on a bottom surface of the display panel, a main FPCB coupled to the display panel and including first and second connecting portions, a first touch FPCB connected to the first touch sensing member and the first connecting portion, a second touch FPCB connected to the second touch sensing member and the second connecting portion, a first touch driving circuit on the first touch FPCB, and a second touch driving circuit on the second touch FPCB. The first touch driving circuit and the first connecting portion may be positioned opposite to each other with respect to the main FPCB. The second touch driving circuit and the second connecting portion may be positioned opposite to each other with respect to the main FPCB.
