Abstract
A touch detection device supplies driving signals generated based on orthogonal carriers and a CDMA scheme to driving electrodes. A touch driving circuit drives the driving electrodes in groups including a first group and a second group, supplies first driving signals based on a designated first frequency and first orthogonal codes set to correspond to the driving electrodes of the first group, respectively, to the driving electrodes of the first group, and supplies second multiple driving signals based on a second frequency orthogonal to the first frequency and second orthogonal codes set to correspond to the driving electrodes of the second group, respectively, to the driving electrodes of the second group.
