Direct connect single layer touch panel
First Claim
1. An apparatus, comprising:
- a connecting board including a plurality of pads, the connecting board configured to be electrically coupled to a first substrate at the plurality of pads, the connecting board comprising a second substrate, different from the first substrate; and
routing formed on the connecting board and coupled to the pads, the routing arranged to electrically connect each of a plurality of discrete sensor elements in a row of the first substrate to one another while providing electrical isolation from sensor elements and traces associated with other rows.

Abstract
A substantially transparent touch sensor panel having co-planar single-layer touch sensors and traces fabricated on a single side of a substrate for detecting single or multi-touch events. The touch sensor elements can be fabricated in columns and rows, with each sensor element in a row adjacent to a sensor element in a column. By using a board as the dielectric to connect traces from multiple sensor elements in each row, rather than using a dielectric layer on the substrate upon which the sensor elements and traces are formed, the sensor elements and traces on the substrate can be formed by simply patterning a single layer of conductive material on the substrate, which can simplify the manufacturing process of the substrate from a complexity and cost perspective.
