Abstract: The present disclosure relates to a touch pad device and a portable computer including the same, and more particularly, to a touch pad device capable of sensing an inputted push of an object, and a portable computer including the same. A touch pad device according to one embodiment includes: a touch pad cover; a substrate disposed under the touch pad cover and including a pressure sensor; and a frame configured to support the substrate, in which a magnitude of a pressure inputted to the touch pad cover is detected on the basis of a change in electrical characteristics outputted from the pressure sensor in response to bending of the substrate.

Abstract: A touch input device may be provided that includes a cover layer; a display module disposed under the cover layer; a substrate disposed apart from the display module at a predetermined distance; and a flexible printed circuit board (FPCB) on which a control circuit for controlling the operation of the display module is mounted. A pressure sensor for sensing touch pressure of an object is formed in a partial area of the FPCB.
