Abstract
A touch detection device includes a panel including a plurality of electrodes regularly arranged in rows and columns, a switch connected to electrodes arranged in a specific column through connection lines, and a sensor driving unit operably coupled to the switch and configured to perform a control operation so that a driving signal of a voltage waveform of a specific cycle is applied to the electrodes. Lengths of the connection lines are differently set according to positions of electrodes arranged in a specific row. The sensor driving unit applies a second driving signal of a reverse voltage waveform to an electrode of one of two rows adjacent to the specific row when an amount of electromagnetic interference (EMI) radiation of a specific connection line to which the driving signal is applied is less than or equal to a threshold.
