主权项

1. A touchscreen comprising:
a liquid crystal display having an upper surface area and a lower surface area; a capacitive array adjacent said lower surface area; an optically transparent electrically conductive layer deposited between said lower surface area and said capacitive array, said layer including:
a first area electrically isolating said liquid crystal display and said capacitive array, said first area including less than said upper surface area, and a second area permitting electrical transmission between said upper surface area and said capacitive array.
