Touch input device

A touch input device which detects a pressure of a touch on a touch surface, the touch input device comprising:

• a display module;
• a substrate for blocking electrical noise or for separating the display module from a circuit board or battery for operation of the touch input device;
• and
• a first electrode disposed on the display module and a second electrode disposed on the substrate,
• wherein a spacer layer is disposed between the first electrode and the second electrode,
• wherein a pressure magnitude of the touch is detected based on a capacitance between the first electrode and the second electrode, and the capacitance is changed depending on the distance between the first electrode and the second electrode,
• wherein the display module is bent by the touch, and the distance between the first electrode and the second electrode is changed due to the bending of the display module,
• wherein the first electrode is disposed on a bendable surface of the display module, and
• wherein the spacer layer is maintained with a predetermined thickness only by a supporting structure which is made of inelastic material and located only in an edge portion of the substrate, and
• wherein the supporting structure is located between the display module and the substrate which is under the display module,
• wherein the second electrode is positioned between a first insulation layer and a second insulation layer, and the second electrode, together with the first insulation layer and the second insulation layer, is fixed as an integral electrode sheet to the substrate.
