Abstract
In one embodiment, a touch input device includes 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.
