Abstract:
1. A mutual capacitance touchscreen, comprising: a first set of electrically conductive traces arranged in rows or columns, and a second set of electrically conductive traces arranged in rows or columns arranged at an angle with respect to the rows or columns of the first set; wherein the first and second sets of traces are electrically insulated from another, each cell comprising a plurality of sub-cell rectangular or square drive electrodes electrically connected to one another by first cross-over traces and a plurality of sub-cell rectangular or square sense electrodes electrically connected to one another by second cross-over traces, the sub-cell drive and sense electrodes being interleaved with respect to, and disposed in between, one another within each cell, the sub-cell sense and drive electrodes being separated by gaps within each cell, the first and second sets of electrically conductive traces comprising and being electrically connected to the drive and sense electrodes; wherein the sub-cell rectangular or square drive or sense electrodes each form a pattern having an unfilled empty center surrounded by an electrically conductive material.
