| 摘要 |
A laminated capacitive touch-pad having a thin film touch-plate electrode deposited upon a first (exterior) surface of a first, relatively thin dielectric layer and having spaced transmitter and receiver electrodes deposited upon a second surface of the first layer within the outline of and opposite to the touch electrode, with a relatively thick backing layer of dielectric material laminated upon the second surface to provide a total thickness, as measured between the furthest opposed surfaces of the first and second layers, as required for high voltage insulation purposes and to provide additional impact strength. The touch, transmitter and receiver electrodes may be of thin film construction.
