Stretchable display devices and touch display devices

Abstract

The invention relates to a stretchable display device and a touch display device. The stretchable display device comprises a display panel for displaying images and a touch panel positioned on top of the display panel. The touch panel contains a first sensing line extending in the first direction and a second sensing line extending in the second direction. The first and second sensing lines are of a chain-like shape in which multiple loops are connected, allowing the sensing lines to accommodate deformation while maintaining electrical performance. This construction supports reliable touch detection when the display unit is stretched, bent, or otherwise deformed, and can be applied to various stretchable display configurations.
