  • Patent number: 11768548
    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.
    Type: Grant

  • Patent number: 10481714
    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.

  • Publication number: 20190243485
    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.

  • Patent number: 8320534
    Abstract: A method for connecting a calling terminal to a called terminal includes establishing a first session to a video server and a call connection request to the called terminal, receiving ringback tone (RBT) video data from the video server using the established first session during a waiting time before a response from the called terminal for the request is received, generating a setup flag to set a connection environment with the called terminal to perform a fast setup between the calling terminal and the called terminal, and transmitting the generated setup flag to the called terminal through a second session established by the called terminal. A system to perform the method includes an establishing unit to establish the first session, an RBT video data receiving unit to receive the RBT video data, a setup flag generating unit, and a setup flag transmitting unit.
