1. A touch screen sensor, comprising:
- a visible light transparent substrate; and
a plurality of spaced apart substantially parallel electrically conductive mesh bars disposed on or in the visible light transparent substrate, each mesh bar comprising a plurality of first traces having a first width and defining a plurality of enclosed open areas, the mesh bar electrically connected to an electrically conductive second trace having a second width greater than the first width for making contact with an electronic device, the second trace comprising a first portion extending along a first direction and a second portion extending along a different second direction, wherein the mesh bar, and the first and second portions of the second trace include a same metal at approximately a same thickness.

Abstract
A touch screen sensor includes a visible light transparent substrate and an electrically conductive micropattern disposed on or in the visible light transparent substrate. The micropattern includes a first region micropattern within a touch sensing area and a second region micropattern. The first region micropattern has a first sheet resistance value in a first direction, is visible light transparent, and has at least 90% open area. The second region micropattern has a second sheet resistance value in the first direction. The first sheet resistance value is different from the second sheet resistance value.
