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.

Pressure detectable touch input device including display module

A touch input device may be provided which includes at least one cover and a display module disposed under the cover, and detects a pressure of a touch input to the cover. The touch input device includes: a housing which includes a bottom plate on which a battery and a mainboard are disposed; and a mid-frame which is disposed within the housing, is disposed under the display module, and is disposed on the battery and on the mainboard. The mid-frame includes a guide member which is disposed on a bottom surface of the mid-frame and is coupled to the bottom plate of the housing.

Touch input device for detecting touch pressure

A touch pressure sensitivity correction method may be provided that includes: defining a plurality of reference points on a touch sensor panel; generating a reference data for a capacitance change amount sensed by applying the same pressure to the plurality of reference points; generating an interpolated data corresponding to a capacitance change amount for a random point present between the plurality of reference points; calculating, on the basis of the reference data and interpolated data, with respect to the reference points and the random point respectively, a correction factor for correcting a sensitivity of a touch input device to a target value; and correcting uniformly for the touch pressure sensitivity of the touch input device by applying the calculated correction factor to each corresponding point.
