Touchscreen using oriented microscopic linear conductive elements
First Claim
1. A cover sheet assembly for a touchscreen system overlying a display, said cover sheet assembly comprising:
- an insulating layer having a surface configured to be disposed over an electrically conductive area of a substrate of the touchscreen system; and
an electrically conductive material disposed on at least a portion of the insulating layer surface, the electrically conductive material comprising a plurality of microscopic linear conductive elements arranged in a pattern that is oriented with respect to a first direction of a first polarization of light emitted by the display such that the electrically conductive material is more transparent to the first polarization of light than to a second polarization of light that is polarized in a second direction that is perpendicular to the first direction.

Abstract
A cover sheet assembly is provided for a touchscreen system. The cover sheet assembly includes an insulating layer having a surface configured to be disposed over an electrically conductive area of a substrate of the touchscreen system. An electrically conductive material is disposed on at least a portion of the insulating layer surface. The electrically conductive material includes a plurality of microscopic linear conductive elements arranged in a pattern that is oriented with respect to a first direction of a first polarization of light such that the electrically conductive material is more transparent to the first polarization of light than to a second polarization of light that is polarized in a second direction that is perpendicular to the first direction.
