  • Patent number: 8618818
    Abstract: This invention offers an electrostatic capacity type touch sensor that can be calibrated in a short period of time at a moment when a finger of operator or the like does not touch a touch pad. An absolute value of a difference (AD0?AD2) between a first output voltage AD0 and a third output voltage AD2 is compared with a first threshold value Vtr1 in step S10. When the difference (AD0?AD2) between the output voltages is smaller than the first threshold value Vtr1, it is judged that the finger of operator or the like does not touch the touch pad, and it is judged which of an offset in a second output voltage AD1 and an offset in the third output voltage AD2 is smaller than the other. When the offset in the second output voltage AD1 is smaller than the offset in the third output voltage AD2, the modification to the second calibration data X1 is permitted.

  • Publication number: 20110199331
    Abstract: The invention provides an electrostatic capacity type touch sensor that is not influenced by a parasitic capacitor formed between a sensor line connected to a touch sensor pad and other signal line and provides a stable sensor output. A sensor line connected to a touch sensor pad is connected to a non-inverting input terminal (+) of a charge amplifier. An LED is disposed in the touch sensor pad, and the cathode of the LED is connected to an LED signal line. Since the LED signal line is disposed adjacent to the sensor line, a parasitic capacitor is formed between the LED signal line and the sensor line. In order to keep the capacitance of this parasitic capacitor constant, a pull-up resistor is connected to the LED signal line. The LED signal line is biased to a power supply potential Vdd by the pull-up resistor.
