First Claim
Patent Images
1. A touch screen sensor having a touch-sensitive surface comprising:
- within a touch sensing area, a electrically conductive micropattern disposed on or in a visible light transparent substrate, wherein the micropattern includes conductive traces with width between about 1 and 10 micrometers; and
one or more light scattering elements in an optically continuous layer of substantially uniform optical density disposed between the micropattern and the touch-sensitive surface, and wherein the light scattering elements comprise microscopic features having a size greater than the width of the conductive traces.
