The inventive concept discloses a capacitive touch system and a coordinate extraction method thereof. The coordinate extraction method has operations of phases 1 and 2.First and second axis coordinates of a first frame are obtained by providing driving signals in a first direction selected in the first phase and performing a sensing in a second direction different from the first direction. First and second axis coordinates of a second frame are obtained by providing driving signals in a second direction selected in the second phase and performing a sensing in the first direction. First and second axis coordinates having a relatively high coordinate precision among the first and second axis coordinates may be finally determined as a touch coordinate. According to the inventive concept, since a touch sensing precision is improved to be strong against a noise, a touch coordinate is more precisely obtained.
