Reduced contrast improved transmission conductively coated transparent substrate
First Claim
1. A reduced contrast, increased transmission, conductively coated panel, comprising:
- a transparent substrate having a first surface and a second surface;
a transparent, conductive layer on at least one surface of said substrate, said conductive layer being in a predetermined pattern such that there is at least one area having a conductive layer thereon and a second area without a conductive layer on said one substrate surface;
a transparent layer of metal oxide overlying said one and said second areas of said one substrate surface whereby visible contrast between said one area and said second area is reduced and light transmission through said coated panel is increased; and
wherein said coated panel is adapted for use in an interactive device.

Abstract
A conductively coated panel for inclusion in a transparent interactive input device useful with an electro-optic display includes a transparent substrate having a transparent, conductive layer on at least one surface. The conductive layer is applied in a predetermined pattern with at least one area having a conductive layer thereon and a second area without a conductive layer. A transparent layer of a metal oxide such as silicon dioxide overlies both areas whereby visible contrast between the areas is reduced and light transmission through the coated panel is increased. An interactive device, and a method for forming an interactive device with the conductively coated panel, are also disclosed.
