  • Touch-panel input device
    Patent number: 9760280
    Abstract: A touch-panel input device as disclosed in the specification comprises a touch panel and an input controller capable of switching between a right-hand two-point touch input sensing mode suitable for the placement of right fingers and a left-hand two-point touch input sensing mode suitable for the placement of left fingers, wherein the input controller senses two-point touches on the touch panel in either of these input sensing modes.
    Type: Grant
    Filed: December 22, 2015
    Date of Patent: September 12, 2017
    Assignee: Rohm Co., Ltd.
    Inventors: Sigehide Yano, Kazunori Hisa, Takashi Oki, Masahide Tanaka

  • Control circuit and control method for touch panel to determine coordinates touched by user
    Patent number: 9104286
    Abstract: A first resistive film is arranged such that one edge thereof is connected to a first terminal, and an edge that is opposite to the aforementioned edge is connected to a second terminal. A second resistive film is arranged with a gap between it and the first resistive film such that one edge thereof is connected to a third terminal. A voltage generating unit applies a predetermined first bias voltage and a predetermined second bias voltage to the first terminal and the second terminal, respectively. A voltage detection unit detects a panel voltage that occurs at the third terminal. A current detection unit detects a panel current that flows through a path including the first terminal, the first resistive film, and the second terminal. A computation unit determines the coordinates touched by the user, based upon the values of the panel voltage and the panel current.
