Patent ID: 10684716

Abstract:
A stretchable panel and a flexible display device are provided. The stretchable panel includes a stretchable substrate and an electrode layer. The stretchable substrate includes multiple island-like structures arranged in an array, and any two adjacent island-like structures are separated from each other and connected via a bridge. The electrode layer includes one or more first sub-electrodes and one or more second sub-electrodes located on the multiple island-like structures. The first sub-electrode is insulated from the second sub-electrode. First sub-electrodes in at least one column of island-like structures are electrically connected sequentially to form a first electrode, and second sub-electrodes on at least one row of island-like structures are electrically connected sequentially to form a second electrode. A touch position and/or a stretched state can be determined based on the change in capacitance between the first electrode and the second electrode.
