Abstract

A touch panel module has a touch panel, a sensation feedback panel, a control unit and a stimulating signal generating circuit. The sensation feedback panel is mounted on the touch panel and has multiple stimulating circuits arranged in a matrix configuration or a non-overlap configuration. The stimulating signal generating circuit electrically connects to the stimulating circuits and the control unit. When the control unit receives a touch signal produced by the touch panel, it controls the stimulating signal generating circuit to output stimulating currents to the stimulating circuits. When a user touches the stimulating circuits, the stimulating current can flow through the user'"'"'s finger to electrically stimulate nerve, thereby achieving the sensation feedback effect to notice the user that the touch panel has been pressed properly to activate desired function.
