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.
Claims15
A patterned substrate, comprising:
- a visible light transparent substrate;
- and
- a plurality of spaced apart regions disposed on or in the visible light transparent substrate, each region comprising an electrically conductive mesh defining a plurality of enclosed open areas, the mesh having an open area greater than about 75 percent and electrically connected to an electrically conductive pad for connection to an electronic device, the mesh and the conductive pad including a same metal at approximately a same thickness.
A patterned substrate, comprising:
- a visible light transparent substrate;
- a first metal mesh disposed on or in the visible light transparent substrate and having a first sheet resistance;
- a second metal mesh disposed on or in the visible light transparent substrate for connection to an electronic device, the second metal mesh electrically connected to the first metal mesh and having a second sheet resistance different than the first sheet resistance, each of the first and second metal meshes having an open area greater than about 75 percent, the first and second metal meshes including a same metal at approximately a same thickness.
A patterned substrate, comprising:
- a visible light transparent substrate;
- an electrically conductive mesh disposed on or in the visible light transparent substrate and comprising a plurality of traces defining a plurality of enclosed open areas, the mesh having an open area greater than about 75 percent;
- and
- a plurality of electrically conductive pad for connection to an electronic device, wherein the mesh and the plurality of conductive pads include a same metal at approximately a same thickness.
