    Abstract: In one embodiment, a touch sensor includes a first electrode, a second electrode, and a spacer layer located between the first electrode and the second electrode. One of the first electrode and the second electrode is a drive electrode to which a drive signal is applied. The other one of the first electrode and the second electrode is a receiving electrode that receives the drive signal by a mutual capacitance between the first electrode and the second electrode. When an external pressure is applied to the first electrode through a display, the first electrode is concavely bent toward the second electrode. The mutual capacitance between the first electrode and the second electrode changes according to a distance between the first electrode and the second electrode. The magnitude of the external pressure according to the change of the capacitance between the first electrode and the second electrode is detected.

    Abstract: A touch input device which includes a display module and is capable of detecting a pressure may be provided. The touch input device includes: a display module including a flat portion and at least one curved portion which extends from the flat portion and is curved with a predetermined curvature; and a pressure detection module which is formed under the display module and detects a touch pressure applied to a surface of the display module. The pressure detection module detects the touch pressure on the basis of a capacitance change amount according to a distance change between a reference potential layer and the pressure detection module. As a result, the touch input device including various types and forms of the display modules is capable of efficiently detecting the touch position and touch pressure.

    Abstract: A sensitivity compensation method of a touch input device sensing a touch pressure may be provided. The sensitivity compensation method includes: detecting a capacitance change amount by applying a pressure to a plurality of points defined on a touch sensor panel; generating a raw data for the capacitance change amount of the defined point; generating a decimal value data for each of the sets by dividing a data value within the set by a maximum value within the set; calculating an average value of each defined point; generating a representative value data by calculating a value corresponding to all the points of the touch sensor panel; calculating a balance factor on the basis of the representative value data; and compensating for a touch pressure sensitivity of the touch input device by using the balance factor.
