<p><P>PROBLEM TO BE SOLVED: To provide a capacity type touch panel which can detect an input operation position accurately even if an input operation surface is upsized and resistances of a detection electrode pattern and its wiring pattern are changed. <P>SOLUTION: A detection resister connected to a detection electrode pattern in series and a stray capacity of the detection electrode pattern form a high-pass filter through which a common mode noise generated in an input operation body passes. As an input operation body comes closer and the stray capacity of the detection electrode pattern becomes larger, a level of the common mode noise passing through the high-pass filter rises, so that an input operation position is detected from an arrangement position of the detection electrode pattern at which the level of the common mode noise rises. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
