A touch sensor is disclosed. The touch sensor includes a touch panel including a plurality of sensing nodes in columns and rows and sensing lines connected to the sensing nodes, a touch sensing unit configured to provide a driving signal to at least one of sensing lines to charge at least one of the sensing nodes during a first time period and discharge voltages on the sensing nodes during a second period, and a charge sharer or equalizer configured to short-circuit the sensing lines during the second time period. |
