Abstract

A shadeless touch hand-held electronic device includes a panel, a memory unit, a touch-sensing cover and a control unit. The touch-sensing cover has a cover and a touch-sensing structure. The cover is disposed on the side of the hand-held electronic device opposite the panel, partial or total area of the touch-sensing structure is disposed on the cover, and the touch-sensing structure has an activation area. The control unit is electrically connected to the touch-sensing structure and the memory unit. After the activation area being triggered, the shadeless touch hand-held electronic device is activated to an operative state.
