<p><P>PROBLEM TO BE SOLVED: To correct deviation of a touch position at an electrostatic capacity type touch panel device detecting a touch position to a sensor panel with a finger or by a coordinate indicator. <P>SOLUTION: To detect a touch position by setting a phase and an AC voltage when a finger touches a panel as contact vector signals and by setting a scalar amount calculated by using the cosine rule from the phase difference and the amplitude of both signals as an AC signal generated by touch with an original finger, a phase correction type touch panel device is characterized in that the AC voltage generated by a parasitic signal when the finger is not present near a surface resistor and the phase difference between both signals with a finger of a capacitive ground human body or a resistive ground human body are eliminated. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
