TOUCHSCREEN USING ORIENTED MICROSCOPIC LINEAR CONDUCTIVE ELEMENTS

摘要

A cover sheet assembly (10) is provided for a touchscreen system (200). The cover sheet assembly includes an insulating layer (12) having a surface (14) configured to be disposed over an electrically conductive area of a substrate of the touchscreen system. An electrically conductive material (16) is disposed on at least a portion of the insulating layer surface. The electrically conductive material includes a plurality of microscopic linear conductive elements (22) 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.
