Abstract: Provided is a touch sensing circuit configured to sense an approach of a conductive object toward a sensor capacitor through measuring a sensor response signal generated by the sensor capacitor in response to a sensing wave signal applied to the sensor capacitor. The touch sensing circuit is connectable to a conversion circuit and a touch detection circuit. The conversion circuit calculates a response signal vector for a frequency component of the sensing wave signal by converting the response signal into a frequency domain representation. The touch sensing circuit includes a baseline vector manager circuit holding a baseline vector and a vector subtraction circuit, and calculates a delta vector which is the vector difference between the baseline vector and the response signal vector received from the conversion circuit. The touch detection circuit detects an approach of a conductive object towards the sensor capacitor on the basis of the calculated delta vector.

Abstract: A touch sensing circuit operable to sense a conductor approaching a sensor capacitance by measuring a response signal obtained from the sensor capacitance according to an applied detection signal includes an A/D converter and a Fourier transform device. The A/D converter samples the response signal with a predetermined cycle, followed by conversion to a digital value and outputs as time-series response data. The Fourier transform device calculates, from the time-series response data, a result of transformation at a detection frequency representing the reciprocal of a cycle of the detection signal and outputs it. The touch sensing circuit converts the response signal to the frequency domain, calculates only components (harmonics or others as needed) of a frequency equal to that of the detection signal required for touch sensing, and supplies them for a touch coordinate calculation process in a subsequent stage.

Abstract: A system and method for input sensing comprises a display device having at least one piezoresistive sensing transistor. During a first period, a first resulting signal is received with a first data line by driving a first piezoresistive sensing transistor of a first subpixel of the display device with a first select signal. The first resulting signal corresponds to a change in resistance of the first piezoresistive sensing transistor. Further, at least one of force information and positional information associated with an input object may be determined at least partially based on the change in resistance.
