US 2019/0155438 A1 · TOUCH INPUT DEVICE

Abstract

A touch input device may be provided that includes: a first cover layer; a spacer layer; a display panel which includes a first substrate layer and a second substrate layer disposed under the first substrate layer; a first electrode and a second electrode which are disposed between the first substrate layer and the second substrate layer; and a third electrode and a fourth electrode which are disposed on the display panel. At least one of the first electrode and the second electrode is used to drive the display panel. A touch position is detected based on a capacitance which changes as an object approaches a touch sensor including at least one of the first electrode, the second electrode, the third electrode, and the fourth electrode and which is detected from the touch sensor. A touch pressure is detected based on a capacitance which is changed by change of a distance between the object and a pressure sensor including at least one of the first electrode, the second electrode, the third electrode, and the fourth electrode and which is detected from the pressure sensor. The spacer layer is disposed between the first cover layer and the pressure sensor.
