摘要:
A multi-touch detecting method is adapted for detecting touched points on a touch panel that includes first and second conductive films. The first conductive film exhibits electric anisotropy, and has a lower resistivity in a first direction. The multi-touch detecting method includes: applying a first voltage to the first conductive film; applying a second voltage greater than the first voltage to the second conductive film; measuring sequentially voltages at different measuring points of the first conductive film; obtaining a first local maximum voltage, a second local maximum voltage and a local minimum voltage from the measured voltages; determining a first location of the touched points based on a location of the measuring point corresponding to the first local maximum voltage; and determining a second location of the touched points based on a location of the measuring point corresponding to the second local maximum voltage.
