  • Patent number: 10664085
    Abstract: A display device with a touch detection function includes a touch detection electrode, first and second electrodes, a touch detection controller, and a force detection controller. The force detection controller performs interpolation processing on reference values to calculate an interpolation value when a reference force is applied to a position in an input surface at which a force has been applied by an object and calculates a force detection value based on a ratio of a detection value detected based on capacitance between first and second electrodes to the interpolation value. The position at which the force is applied is specified based on a position detected by the touch detection controller as a position of contact with the input surface by the object. The reference values are detected based on the capacitance between the first and second electrodes when the reference force is applied to reference positions.
