Abstract
The present disclosure provides a touch panel and a method for manufacturing the same, and an electronic device. The touch panel includes a display area and a non-display area. The non-display area includes a bending area and a wire-switching area. By disposing an edge of the inorganic layer between the display area and the wire-switching area, disposing an edge of the encapsulation layer between an edge of the inorganic layer and the bending area, and disposing a plurality of wire-switching holes in the wire-switching area, so that signal traces are exposed by the wire-switching holes, thus preventing materials of the encapsulation layer from remaining in the wire-switching holes.
