Abstract
A touch input device capable of detecting a pressure of a touch on a touch surface includes: a display module including a display panel; a substrate which is located under the display module and is spaced apart from the display module by a spacer layer; and a pressure electrode. An electrical signal, which is changed according to a capacitance between the pressure electrode and the substrate, is detected from the pressure electrode, and the capacitance changes depend on a change of a relative distance between the pressure electrode and the substrate, such that the pressure of the touch is detected based on the capacitance.
