Abstract
A technique for reading the columns and rows of a touch sensor provides several advantages, including scalability to touch sensors with high column/row counts. Reading the touch sensor relies on combining the row or column outputs of the touch sensor, during column and/or row excitation of the touch sensor, with the resulting combined signal or signals transformed into the frequency domain and touch detection based on evaluation of the frequency-domain values corresponding to the excitation frequencies.
