Electrode sheet and touch input device

摘要

A touch input device capable of detecting a pressure of a touch on a touch surface may be provided that includes: a display panel; and an electrode disposed under the display panel. When a pressure is applied to the touch surface, a distance between the electrode and a reference potential layer is changed. A capacitance which is detected at the electrode is changed according to the distance change. The display panel includes a first area and a second area. Under a same distance change condition, a capacitance change amount detected at the electrode disposed under the second area is greater than a capacitance change amount detected at the electrode disposed under the first area.

1. A touch input device capable of detecting a pressure of a touch on a touch surface, the touch input device comprising:
a display panel; and an electrode disposed under the display panel; wherein, when a pressure is applied to the touch surface, a distance between the electrode and a reference potential layer is changed; wherein a capacitance which is detected at the electrode is changed according to the distance change; wherein the display panel comprises a first area and a second area; wherein a change of the distance between the electrode disposed under the second area and the reference potential layer when a pressure is applied to the second area is less than a change of the distance between the electrode disposed under the first area and the reference potential layer when the same amount of the pressure is applied to the first area; and wherein, under a same distance change condition for the distance between the electrode and the reference potential layer, a change amount of the capacitance detected at the electrode disposed under the second area is greater than a change amount of the capacitance detected at the electrode disposed under the first area.
