Abstract
Disclosed herein are optical stacks that are stable to light exposure by incorporating one or more UV-blocking layers.
Claims20
A touch sensor comprising:
- a first basic transparent conductor having a first substrate and a first plurality of networking silver nanostructures;
- an OCA layer,
- a second basic transparent conductor having a second substrate and a second plurality of networking silver nanostructures;
- and a third substrate,
- wherein the third substrate has a surface that receives incident light and touch input, the second basic transparent conductor is more proximate to the incident light than the first basic transparent conductor, and
- wherein at least one of the second substrate, the third substrate or the OCA layer is a UV-blocking layer.

A touch screen comprising:
- a first basic transparent conductor having a first substrate and a first plurality of networking silver nanostructures formed on the first substrate;
- an OCA layer, and
- a second basic transparent conductor having a second substrate and a continuous conductive film formed on the second substrate;
- wherein the second substrate has a surface that receives incident light and touch input, the second basic transparent conductor is more proximate to the incident light than the first basic transparent conductor, and
- wherein at least one of the second substrate or the OCA layer is a UV-blocking layer.
