Abstract
A polarizing device has a polarizing layer, a first protection layer, a second protection layer, a conductive layer, an insulating layer, an electrode layer and a hardening coating layer. When a user touches a monitor, which is implemented with the polarizing device, by his/her finger, the coordinate of the touch point will be detected by monitoring the interference caused on the equivalently generated electric filed.
Claims9
A polarizing device integrated with a touch sensor comprising:
- a polarizing layer;
- a first protection layer, positioned on said polarizing layer, made by non-conductive materials;
- a conductive layer, tightly integrated with said first protection layer;
- an electrode layer for propagating electrical signals;
- and
- a hardening coating layer, positioned on the electrode layer, made by non-conductive material,
- wherein electrodes of said electrode layer generates a steady electrical field over said conductive layer.
