摘要： An indicator position detecting device and method are provided, which allow accurate position detection without the influence of noise in detection of the position of an indicator (e.g., a finger, a stylus pen) by a capacitive coupling system. To a conductor pattern in which plural conductors for signal transmission and plural conductors for signal reception intersect with each other, signals with frequencies different from each other are simultaneously supplied to the plural conductors on the transmission side, and signals of respective frequencies corresponding to the plural signals with the different frequencies are detected on the reception side, to thereby detect the position of an indicator on the conductor pattern. The amount of noise of each of the detected frequencies is detected. Any frequency that cannot be properly detected due to noise is switched to another frequency, and detection is carried out based on the newly selected frequency.

The detection sensor includes a plurality of first conductors disposed in a first direction, a plurality of second conductors disposed in a second direction crossing with the first direction, and a pressure sensitive material disposed between the first and second conductors and having a variable resistance characteristic.

When the pressure applied to the detection sensor is higher than the threshold, detection signals corresponding to variation in resistance characteristic of the pressure sensitive material are supplied.
