Original Abstract Submitted

this document describes systems and techniques directed at extending touch-sensitive regions in electronic devices. in aspects, an electronic device includes a cover layer, a touch sensor panel, and an electronic visual display panel (“display panel”). the cover layer includes a top face and a side face. the touch sensor panel has a first sensing region corresponding to a surface of the top face and a second sensing region at least partially corresponding to a second surface of the side face. the display panel has an active area corresponding at least partially to the first surface of the top face. the active area of the touch sensor panel is greater than an active area of the display panel. despite the display panel and the touch sensor panel having different active area sizes, an integrated circuit is configured to control both of them, maximizing an internal volumetric efficiency.
