Abstract
An electro-optic element including: (i) an electrochromic medium; (a) a first electro-optic conductive layer that is substantially transparent disposed to one side of the electrochromic medium; (b) a second electro-optic conductive layer disposed to another side of the electrochromic medium; (c) a capacitive touchscreen conductive layer disposed on an opposite side of the first electro-optic conductive layer as the electrochromic medium, the capacitive touchscreen conductive layer comprising a pattern and being substantially transparent; (d) a capacitive touchscreen insulating layer disposed between the capacitive touchscreen conductive layer and the first electro-optic conductive layer; and (e) electrical circuitry configured (i) to drive the capacitive touchscreen conductive layer and at least one of the first electro-optic conductive layer and the second electro-optic conductive layer together with substantially in-phase AC voltage and (ii) to provide an input DC voltage difference between the first electro-optic conductive layer and second electro-optic conductive layer is substantially constant.
