  • Patent number: 10775928
    Abstract: A force detection apparatus includes: a force detector that includes an electrode and a conductor facing the electrode across a first and a second layers and outputs a force signal value before correction; and a force detection controller outputting a force signal value after correction having a linear relationship with a force. In a first range of force in which the first layer is deformed and the second layer is not deformed, the force detection controller calculates the force signal value after correction, based on a product of the force and a first constant. In a second range of force in which the first and second layers are deformed, the force detection controller calculates the force signal value after correction, based on a sum of a product of a threshold and the first constant and a product of a difference between the force and the threshold and a second constant.

  • Patent number: 10768755
    Abstract: A common electrode for a display, which is originally provided in a liquid crystal display element, is also used as one (drive electrode) of a pair of electrodes for a touch sensor, and the other (detection-electrode-for-the-sensor) of the pair of electrodes is newly formed. An existing common drive signal as a drive signal for display is used in common for a drive signal for the touch sensor. A capacitance is formed between the common electrode and the detection-electrode-for-the-sensor, and touch detection is performed by utilizing a change of this capacitance caused by a finger touch of a user. Thus, a display device with a touch sensor is also applicable to a mobile device in which electric potential of the user is inconstant in many cases. The newly-provided electrode is only the detection-electrode-for-the-sensor, and it is unnecessary to newly prepare a drive signal for the touch sensor.
