Abstract:
A polarizer integrated with conductive material and a process for forming a polarizer integrated with conductive material are disclosed. A polarizer can be integrated with conductive material to form a portion of a touch sensor panel. In one example, a layer of conductive film forming either the row or column traces can be patterned on a surface of a substrate in the polarizer. In another example, the layer of conductive film can be patterned on a viewing angle compensation film of the polarizer. One or more of the polarizer's polarizing layer, protective substrates or viewing angle compensation film can act as a dielectric between the conductive material forming the rows and column traces in the stack-up. As a result, the clear polymer spacer acting as a dielectric in touch panels can be removed, reducing the thickness of the touch screen stack-up.
