A surface treatment having plural layers of dichroic materials is formed on the substrate. The layers are tapered in thickness, increasing from about a lower edge to about an upper edge. A spectral band of incident photonic energy is concentrated on a target by way of the surface treatment. The spectral band is consistent for a range of angles of incidence to the surface treatment.Type: ApplicationFiled: April 28, 2011Publication date: November 1, 2012Inventor: Angus Wu

Patent number: 8264466Abstract: Disclosed is a transparent touch screen construction that includes a pattern of layer stacks disposed on a substrate. The layer stacks each include a transparent conductor layer and an intermediate layer positioned between the substrate and the transparent conductor layer. The intermediate layer has a refractive index that is lower than that of the transparent conductor layer and that of the substrate. The construction of the layer stacks reduces the difference in visible light transmission between the areas of the substrate covered by the stacks and the areas of the substrate left exposed by the stacks. Also disclosed are methods for reducing the visibility of a patterned transparent conductor in a touch screen by disposing an intermediate layer pattern between a substrate and a transparent conductor pattern, the intermediate layer pattern and transparent conductor pattern being coincident.Type: GrantFiled: March 31, 2006Date of Patent: September 11, 2012Assignee: 3M Innovative Properties CompanyInventors: Jonathan P.
