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 for detecting a touch pressure including: a display panel; a pressure sensing unit to detect the touch pressure; a pressure sensor controller connected to the pressure sensing unit; and a first PCB. The pressure sensor is formed on the display panel. A first connection line pattern having a first access portion formed at one end is formed on the first PCB. The other end is connected to the pressure sensor controller. A conductive trace which extends from the pressure sensor and includes a second access portion formed on one end is formed on the display panel. The first access portion of the first connection line pattern and the second access portion of the conductive trace are connected to each other by a conductive adhesive member disposed between the first access portion of the first connection line pattern and the second access portion of the conductive trace.
