Abstract:
An electrode sheet including an electrode layer and a support layer may be provided. The electrode layer includes a first electrode and a second electrode. The electrode sheet is used to detect a capacitance change between the first electrode and the second electrode, which is changed according to a relative distance change between the electrode layer and a reference potential layer disposed apart from the electrode sheet. The support layer is made of a material which is bent when a pressure is applied thereto and which is restored to its original state when the pressure is released therefrom.

In one embodiment, a touch input device capable of detecting a pressure of a touch on a touch surface includes a display panel and an electrode disposed under the display panel. An electrical characteristic detected at the electrode is changed by the bending of the display panel.

A pressure detection sensitivity of the first area is higher than a pressure detection sensitivity of the second area. When the first area and the second are bens to the same degree, a change amount of the electrical characteristic detected when a pressure is applied to the second area is greater than a change amount of the electrical characteristic detected when a pressure is applied to the second area.
Abstract:
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.
