ELECTRODE SHEET AND TOUCH INPUT DEVICE
First Claim
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,and wherein, 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.

Abstract
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.

11. An electrode sheet comprising:
-
a first insulation layer and a second insulation layer; and an electrode located between the first insulation layer and the second insulation layer, wherein a capacitance which is detected at the electrode is changed according to a relative distance change between the electrode sheet and a reference potential layer which is disposed apart from the electrode sheet, wherein the electrode sheet comprises a first area and a second area, and wherein, under a same distance change condition, a capacitance change amount detected at the electrode disposed in the second area is greater than a capacitance change amount detected at the electrode disposed in the first area. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
