Patent ID: 8564542

Claim:
A multi-touch detecting method adapted for detecting touched points on a touch panel, the touch panel including first and second conductive films insulated from each other and coupled electrically to each other through touch, the first conductive film exhibiting electric anisotropy, and having a lower resistivity in a first direction, the multi-touch detecting method comprising: applying a first voltage to the first conductive film; applying a second voltage greater than the first voltage to the second conductive film; obtaining a first local maximum voltage, a second local maximum voltage and a local minimum voltage from voltages measured at a plurality of different measuring points of the first conductive film, the measuring point corresponding to the local minimum voltage being located between the measuring point corresponding to the first local maximum voltage and the measuring point corresponding to the second local maximum voltage; determining a first location of the touched points in a second direction transverse to the first direction based on a location of the measuring point corresponding to the first local maximum voltage in the second direction; and determining a second location of the touched points in the second direction based on a location of the measuring point corresponding to the second local maximum voltage in the second direction.
