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.
