Abstract
An electronic touch screen has a substrate having a glass transition temperature Tg below 300° C. The touch screen additionally has a first refractive index matched conductive layer formed on the substrate, a dielectric layer formed on the first index matched conductive layer, and a second index matched conductive layer formed on the dielectric layer. Further, the electronic touch screen has a set of contacts operatively coupled to the first and second index matched conductive layers, which are coupleable to an electronic circuit.
