  • Touch panel system capable of determining a pressing force and display device with the touch panel system
    Patent number: 11972084
    Abstract: A touch panel system includes a touch panel, a cover member overlapping the touch panel, and a controller. The controller includes a position detection unit configured to detect a position of a pointer, based on a signal value obtained from a position detection electrode, an amplification processing unit configured to perform amplification processing on at least one signal value in a pressing force detection range corresponding to the position of the pointer detected by the position detection unit among signal values obtained from a pressing force detection electrode, and a pressing force detection unit configured to calculate magnitude of a pressing force generated by the pointer, based on a signal value after the amplification processing being a signal value in the pressing force detection range including a signal value obtained by amplification by the amplification processing unit.

  • In-cell touch panel
    Patent number: 11947749
    Abstract: An in-cell touch panel device includes a first substrate, a plurality of color filters formed on a layer on an opposite side of a touch surface with respect to the first substrate, a transmitter electrode formed on a layer on an opposite side of the touch surface with respect to the plurality of color filters, a receiver electrode formed on a layer closer to the touch surface side with respect to the plurality of color filters, and a second substrate, a pixel electrode being disposed on the second substrate. The transmitter electrode includes a gap portion formed in a portion overlapping a space between adjacent ones of the plurality of color filters in a plan view.
