Claim Text:
1. A method for determining a touch location of a projected capacitive touch sensor, comprising: providing a substrate with a plurality of non-overlapping areas, wherein each non-overlapping area includes a horizontal detection electrode in a first column and a second column with a plurality of vertical detection electrodes; measuring a first mutual capacitance between the horizontal detection electrode and a vertical detection electrode from the plurality of vertical detection electrodes; measuring a second mutual capacitance between the horizontal detection electrode and another vertical detection electrode from the plurality of vertical detection electrodes; determining one or more horizontal detection electrode and vertical detection electrode combinations based on a change in the first mutual capacitance and the second mutual capacitance; determining a digitized capacitance value based on the change in the first and the second mutual capacitances; and determining the touch location based on a location of the one or more determined horizontal detection electrode and vertical electrode combinations and the digital capacitance value.
