ABSTRACT:
A component for an information display device has a transparent substrate having a surface that has a first refractive index. The surface is selectively coated in a pattern comprising a transparent electrically conductive layer disposed at least at a first region of the surface and at a second region of the surface. The first region of the surface is separated from the second region by a third region that is devoid of the transparent conductive layer. The transparent conductive layer has a second refractive index that is higher than the first refractive index. The first, second and third regions are commonly overcoated with a transparent layer comprising non-conductive nanoparticles, the overcoating layer being disposed over the transparent conductive layer at the first and second regions and also disposed over the third region that is devoid of the transparent conductive layer. The refractive index of the layer comprising nanoparticles is higher than the first refractive index.
