Touch Panel with Multi-Touch Function and Method for Detecting Multi-Touch Thereof

Abstract

A touch panel with a multi-touch function and a method for detecting a multi-touch thereof are provided. The touch panel includes transparent conductive substrate, a transparent conductive film, first conducting wires, second conducting wires and a main detecting module. The transparent conductive film is disposed on the transparent conductive substrate. The two first conducting wires and second conducting wires are disposed at four corresponding sides of the transparent conductive substrate, to provide a constant voltage. A dividing voltage corresponding to the constant voltage is generated while the transparent conductive film is touched to conduct the transparent conductive film and transparent conductive substrate. The main detecting module obtains a touch resistance value based on the constant voltage and the dividing voltage, compares the touch resistance value with a preset resistance value and determines that a multi-touch mode is executed when the touch resistance value is less than the preset resistance value.
