IN-VEHICLE INPUT DEVICE

摘要

An in-vehicle input device includes a touch panel including a lower electrode, an upper electrode, and a spacer, and is capable of detecting a capacitance between the lower electrode and the upper electrode. The device has an operation surface located above the upper electrode. The operation surface includes a plurality of operation areas. The spacer has a plurality of openings that coincide with the operation areas in plan view. The device further includes a suppression layer that is disposed between the operation surface and the upper electrode or disposed on an upper surface of the operation surface. The suppression layer eliminates or reduces formation of a capacitance between the upper electrode and an operator. The device detects an input operation based on a change in distance between the lower electrode and the upper electrode in response to pressing any of the operation areas by the operator.

1. An on-vehicle input device comprising:
a touch panel including:
a lower electrode;an upper electrode facing the lower electrode;an operation surface located above the upper electrode, the operation surface including a plurality of operation areas;a spacer disposed between the lower electrode and the upper electrode, the spacer having a plurality of openings disposed under the operation areas such that the operation areas are superimposed on the corresponding operation areas in plan view; and a suppression layer disposed between the operation surface and the upper electrode, or disposed on an upper surface of the operation surface, the suppression layer eliminating or reducing formation of a capacitance between the upper electrode and an operator, wherein the device is configured to detect an input operation by an operator, based on a change in a distance between the lower electrode and the upper electrode in the openings in response to the operator's pressing any of the operation areas.
