Touch input device

A touch input device comprising:

• an organic light emitting display module comprising a reference potential layer;
• a substrate located under the organic light emitting display module, spaced apart from the organic light emitting display module;
• a pressure sensor comprising a pressure electrode outputting a first sensing signal for detecting a touch pressure and which is attached on the substrate;
• a touch sensor comprising a plurality of drive electrodes to which a driving signal is applied and a plurality of receiving electrodes outputting a second sensing signal for detecting a touch position;
• and
• a controller which detects a magnitude of the touch pressure based on the first sensing signal,
• wherein the organic light emitting display module is bent by the touch pressure,
• wherein a distance between the pressure electrode and the reference potential layer is change according to a bending of the organic light emitting display module, and
• wherein the first sensing signal comprises an electrical characteristics information changed according to the distance.
