Abstract
A touch pad with a feedback function and a touch device using the same are provided. The provided touch pad includes a touch sensing film layer and a vibration film layer, where the vibration film layer is disposed above the touch sensing film layer and includes a permanent charge layer. Moreover, the vibration film layer is configured for generating vibration in response to a touch event on the touch sensing film layer.
Claims25
A touch pad with a feedback function, comprising:
- a touch sensing film layer;
- and
- a vibration film layer, disposed with the touch sensing film layer and comprising a permanent charge layer, wherein the vibration film layer is configured for generating vibration in response to a touch event on the touch sensing film layer.
A touch device, comprising:
- a display module, configured to be served as a display interface of the touch device;
- and
- a touch pad with a feedback function, comprising:
- a touch sensing film layer, disposed above the display module, configured to be served as an input interface of the touch device;
- and
- a vibration film layer, disposed above the touch sensing film layer and comprising a permanent charge layer, wherein the vibration film layer is configured for generating vibration in response to a touch event on the touch sensing film layer.
A vibration film layer, suitable for a touch pad, and the vibration film layer comprising:
- a first electrode layer, disposed above a touch sensing film layer of the touch pad;
- a spacer layer, disposed above the first electrode layer;
- a permanent charge layer, disposed above the spacer layer;
- and
- a second electrode layer, disposed above the permanent charge layer,
- wherein the first and the second electrode layers coordinate with the permanent charge layer to generate vibration in response to a touch event on the touch sensing film layer.
