Abstract
A touch panel system includes a touch panel having sense lines, and drive lines which intersect the sense lines and form capacitance with the sense lines, a touch panel controller for processing signals of the sense lines, and a drive line driving circuit for driving the drive lines in parallel. The touch panel controller includes a subtracting section for finding differences in signals between the sense lines adjacent to each other, a decoding section for calculating a distribution of differences between the capacitances by calculating an inner product of code sequences for driving the drive lines in parallel and difference output sequences which correspond to the code sequences, a touch detecting section for obtaining touch information based on the distribution of differences between the capacitances calculated by the decoding section, and a region setting section for setting an effective region in the touch panel based on the touch information.
