Abstract: In one embodiment, a touch input device capable of detecting a pressure of a touch on a touch surface is disclosed. The touch input device includes a substrate and a display module. A common voltage electrode is disposed within the display module. The touch input device further comprises an electrode which is disposed at a position where a distance between the electrode and the common voltage electrode changes according to the touch on the touch surface. The distance changes according to a magnitude of the pressure of the touch. Further, an electric signal depending on the distance is outputted from the electrode.

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.

Abstract: A fingerprint sensing method based on touch pressure in a black screen mode of a touch input device according to the embodiment of the present invention includes: sensing first pressure which has a value equal to or greater than a first predetermined threshold value and is applied by an object in the black screen mode; determining continuously after sensing the first pressure whether second pressure which has a value equal to or greater than a second predetermined threshold value and is different from the first pressure is sensed or not; recognizing a fingerprint of the object when the second pressure is sensed; determining whether or not the recognized fingerprint is identical to a fingerprint previously registered in the touch input device; and performing a predetermined operation when the recognized fingerprint is identical to the previously registered fingerprint.

Abstract: A smartphone may include a first cover layer and an LCD panel located under the first cover layer. The smartphone may include a backlight unit which may be located under the LCD panel. The smartphone may include a touch sensor which may sense touch in a capacitive manner. The backlight unit may include a pressure sensor and a spacer layer. The pressure sensor may include one or more electrodes formed in a single layer attached on the second cover layer and spaced apart from the reflective sheet. A driving signal may be applied to the touch sensor. A touch position may be detected by a sensing signal which may be output from the touch sensor. A magnitude of a touch pressure may be detected based on a change amount of capacitance which may be output from the pressure sensor.
