Transparent conductive coating for capacitive touch panel or the like |
摘要 |
This invention relates to a transparent conductive coating that is substantially transparent to visible light and is designed to have a visible reflectance which more closely matches that the visible reflectance of the underlying substrate. In certain example embodiments, the transparent conductive multilayer coating includes a silver layer(s) and may be used as an electrode(s) in a capacitive touch panel so as to provide for an electrode(s) transparent to visible light but without much visibility due to the substantial matching visible reflection design. |

1. A capacitive touch panel, comprising:
a substrate; a multi-layer transparent conductive coating supported by the substrate, wherein the multi-layer transparent conductive coating comprises at least one conductive layer comprising silver located between at least a first dielectric layer and a second dielectric layer, wherein the multi-layer transparent conductive coating, comprising at least the conductive layer comprising silver located between at least the first dielectric layer and the second dielectric layer is patterned into a plurality of electrodes for the touch panel; a processor which measures capacitance between electrodes in detecting touch position on the touch panel, wherein the electrodes formed from the multi-layer transparent conductive coating are formed substantially in a common plane substantially parallel to the substrate, and wherein there is no more than a 2.0 difference at 600 nm between (a) a glass side visible reflectance percentage of the multi-layer transparent conductive coating on the substrate in areas where the coating is present, and (b) a visible reflectance percentage of the substrate in at least some areas where the multi-layer transparent conductive coating is not present. |
