1. A touch input device comprising:
- a cover layer;
a touch sensor;
a display panel which is located under the cover layer;
a pressure electrode which is located under the display panel; and
a first converter which converts a signal comprising information for electrical characteristics outputted from the pressure electrode to a digital signal;
wherein a driving signal is applied to the touch sensor and a touch position is detected from a sensing signal which is outputted from the touch sensor; and
wherein a magnitude of a touch pressure is detected from the digital signal converted by the first converter.
