Linear device value estimating method, capacitance detecting method, integrated circuit, touch sensor system, and electronic device

Abstract

A touch sensor panel includes vertical & horizontal electrodes each respectively including a repeat of first & second basic shapes connected to one another in a vertical & horizontal directions, the first & second basic shapes each including a fine wire, respectively provided on vertical & horizontal electrode surfaces, and arranged at intervals; and a plurality of linear devices at respective intersections of the electrodes. A method includes driving the vertical electrodes in parallel on a basis of code sequences di for each of the linear devices so as to output, along the horizontal electrodes, linear sums of respective outputs corresponding to the linear devices; and estimating respective values of the linear devices along the horizontal electrodes on a basis of an inner product operation of (i) the linear sums outputted along the horizontal electrodes and (ii) the code sequences di.
