Abstract: A pressure detection module may be provided that includes: a first electrode and a second electrode which are located on an insulation layer; and an elastic foam. The elastic foam is located between the first and the second electrodes and a reference potential layer located apart from the pressure detection module. A capacitance between the first electrode and the second electrode is changed according to a relative distance change between the reference potential layer and the first and the second electrodes through a transformation of the elastic foam. A magnitude of a pressure which causes the elastic foam to be transformed is detected according to the capacitance change.

The backlight unit may include a pressure sensor and a spacer layer. The pressure sensor includes a plurality of electrodes formed in a single layer attached on the second cover layer and spaced apart from the reflective sheet. A driving signal is applied to the touch sensor and a touch position is detected by a sensing signal. A magnitude of a touch pressure is detected based on a change amount of capacitance which is output from the pressure sensor and which is changed according to a distance between the pressure sensor and an electrode located within the LCD panel. The pressure sensor is attached on the second cover layer as an integral sheet including insulation layers.

Abstract: A sensitivity compensation method of a touch input device sensing a touch pressure may be provided. The sensitivity compensation method includes: defining reference points spaced apart from each other on a touch sensor panel; generating a reference data corresponding to an electrical characteristic sensed by applying a predetermined pressure to the reference points; generating, on the basis of the reference data, an interpolated data corresponding to an electrical characteristic for a random point present between the reference points; calculating, on the basis of the generated reference data and interpolated data, with respect to the reference point and random point respectively, a compensation factor for compensating a sensitivity of the touch input device to a target value; and compensating uniformly for the sensitivity of the touch input device by applying the calculated compensation factor to each corresponding points.
