Abstract
A frequency controlled electro-optical device includes a substrate having transparent conductive control sections patterned thereon to selectively control the optical state of an electro-optical layer. Each of the control sections are partially electrically isolated from each other by crack lines, which allows for electrical communication between adjacent/proximate control sections to occur. As such, an electrical control signal applied directly to one control section forms an electric field in that control section, and also induces an electrical field in adjacent control sections that are not in direct receipt of the control signal. Therefore, the number of electrical connections required for coupling to a driving circuit to operate the device is minimized, thereby allowing the device to be fabricated with reduced complexity and cost.
