Touch input device which detects a magnitude of a touch pressure

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;
• a first converter which converts an analogue signal to a digital signal, the analogue signal comprising information for electrical characteristics outputted from the pressure electrode;
• a drive unit which applies a driving signal to the touch sensor;
• a sensing unit which receives a sensing signal from the touch sensor and detects a touch position;
• and
• a pressure detector which detects a magnitude of a touch pressure from the digital signal converted by the first converter;
• wherein the first converter and the pressure detector are provided as separate components;
• and
• wherein the sensing signal is passed through an integrator or an amplifier and then is converted into a digital signal by a second converter, the second converter being separate from the first converter.
