Capacitive touch panel

A capacitive touch panel comprising:

• a touch panel having a conductive plane and plural detecting points;
• a multiplex selector electrically connected to the plural detecting points of the touch panel;
• a first switch electrically connected to the above multiplex selector;
• a first resistor having a first resistance value;
• a second switch electrically connected to the first resistor and the first switch;
• a capacitor having a capacitance value, the capacitor electrically connected to the above first switch and the second switch;
• a third switch electrically connected to the capacitor;
• an analog to digital converter;
• a fourth switch electrically connected to the analog to digital converter and the third switch;
• and
• an integrating circuit electrically connected to the second switch and the fourth switch,
• wherein the third switch is switched to a DC power source and the switch is switched to such capacitor for charging such capacitor;
• the touching point and the conductive plane of plural detecting points, there is a conductive resistor existed individually between each detecting point and the touching point;
• there the conductive resistors have an individual resistance value;
• the third switch is switched to the fourth switch so to make the analog to digital converter electrically connect to the capacitor to read a first voltage value after the capacitor is charged;
• the first switch is switched to the capacitor so to make the capacitor charge a floating capacitor applied to a contacting point on the touch panel;
• and the integrating circuit records an absolute value of a current flowing through the first resistor.
