1. A touch screen apparatus comprising:
- a first touch panel having a first touch sensor whose capacitance is changed by a user'"'"'s touch;
a second touch panel having a second touch sensor whose resistance value is changed by a user'"'"'s touch; and
a touch sensing circuit for generating and outputting three-dimensional (3D) touch information by sensing a touch position through the first touch sensor and sensing a touch force through the second touch sensor on the basis of a touch synchronization signal.
