Abstract
An analog touch panel comprising two flexible elements, each comprising a flexible membrane coated with a thin layer of conductive material. The elements are oriented so that the conductive coatings are facing each other when the touch panel is assembled. A network of diametrically opposite segmented busbars is formed on the conductive surface of each membrane by screening a conductive ink thereon. Patterned conductive trace members electrically couple the busbars to a conductive trunk, the tail end of which terminates at a connector device. The traces are patterned in a manner such that compensation is provided for positionally caused differences in resistance which otherwise would occur due to the use of conductive inks.
