TOUCH SENSOR PANEL, TOUCH DETECTION DEVICE AND TOUCH INPUT DEVICE COMPRISING SAME

摘要

In one embodiment, a touch input device includes a first electrode; a second electrode located on one side of the first electrode; a display disposed on one side of the first electrode opposite to the second electrode; and a spacer layer between the first electrode and the second electrode. One of the first electrode and the second electrode is a drive electrode, and the other is a receiving electrode that receives the drive signal by a mutual capacitance between the first electrode and the second electrode. When an external pressure is applied to the first electrode through the display, the first electrode is concavely bent toward the second electrode. The mutual capacitance between the electrodes changes according to a distance between the electrodes. The magnitude of the external pressure according to the change of the capacitance between the electrodes is detected.
