    • A field linearization pattern and a touch sensor incorporating same are disclosed. The touch sensor includes a polygonal field linearization pattern disposed around a touch sensitive area. The field linearization pattern includes a first side and a second side that intersect at a first corner. The field linearization pattern further includes an inner row and an outer row of discrete conductive segments. The inner row includes a conductive corner segment at the first corner. The conductive corner segment extends along a portion of the first and second sides of the linearization pattern. The touch sensor further includes electronics configured to detect a location of an input touch applied to the touch sensitive area by generating an electrical current in the linearization pattern. A current flowing from the first side to the second side of the linearization pattern is substantially confined within the linearization pattern.

    • A pattern for linearizing an electric field and a touch sensor incorporating same are disclosed. The touch sensor includes an electrically resistive film that covers a touch sensitive area. The touch sensor further includes two or more substantially parallel polygonal rows of electrically conductive segments disposed on the resistive film and surrounding the touch sensitive area. Each edge of each row has one or more middle electrically conductive segments disposed between two end electrically conductive segments. Gaps separate adjacent conductive segments in a row. A middle conductive segment in a row fully overlaps a middle conductive segment in an adjacent row. The overlap defines a full overlap region. The touch sensor further includes a discrete electrically insulative segment disposed in the resistive film in the full overlap region. The insulative segment increases the electrical resistance between the two middle conductive segments.
    • 公开了一种用于线性化电场的图案和结合其的触摸传感器。 触摸传感器包括覆盖触敏区域的电阻膜。 触摸传感器还包括设置在电阻膜上并包围触摸敏感区域的两个或更多个大致平行的导电段的多边形行。 每行的每个边缘具有设置在两个端部导电段之间的一个或多个中间导电段。 间隔相邻的导电段连续。 行中的中间导电段完全重叠相邻行中的中间导电段。 重叠定义了完全重叠区域。 触摸传感器还包括在完全重叠区域中设置在电阻膜中的分立的电绝缘段。 绝缘段增加两个中间导电段之间的电阻。
