<p><P>PROBLEM TO BE SOLVED: To improve a detection resolution of a display device that employs an electrostatic capacity coupling type touch panel equipped with a transparent conductive film serving as a detection film. <P>SOLUTION: A plurality of electrode terminals 102 is provided such that at least three electrode terminals 102 are aligned in each side of the detection transparent conductive film 101. A touch panel control circuit is provided for selecting one of two to four numbers of electrode terminals from among the plurality of electrode terminal 102 of the detection transparent conductive film 101, applying an AC signal provided from a signal source 105 through a current detection resistor (r) 103, and then detecting a current that flows through each of the selected electrode terminals. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
