Abstract
A touch input device capable of detecting a pressure of a touch on a touch surface includes: a display module and a pressure electrode. The display module includes a display panel and a reference potential layer. An electrical signal, which is changed according to a capacitance between the pressure electrode and the reference potential layer, is detected from the pressure electrode and the capacitance changes depend on a change of a relative distance between the pressure electrode and the reference potential layer, such that the pressure of the touch is detected based on the capacitance.
