Abstract: A hand-held electronic device including a body, a touch-sensing display area, and a holding area is provided. The touch-sensing display area located at a surface of the body is divided into several sub-touch-sensing areas disposed at a part of a surrounding region of the touch-sensing display area. The sub-touch-sensing areas have at least one access-sensing region. The access-sensing region is used for sensing a touch-control action so as to render the hand-held electronic device to perform a function corresponding to the touch-control action. The holding area is disposed outside the sub-touch-sensing areas. When a user only intends to hold the hand-held electronic device, the user's hands can put on the holding area and the hand-held electronic device would not perform any corresponding function.
