Abstract

The present disclosure relates to a touch circuit and a touch sensing method. A touch circuit may include a driving circuit configured to transmit a driving signal to a touch electrode, a sensing circuit configured to sense a change in capacitance generated in the touch electrode, and a touch control circuit configured to control a polarity of the driving signal transmitted by the driving circuit. The polarity of the driving signal controlled by the touch control circuit may be determined based on a location of the touch electrode. Touch sensitivity can be improved by differently controlling a polarity of a driving signal transmitted to an adjacent touch electrode.
