Abstract
According to one embodiment, there is provided 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 right angles with respect to the rows or columns of the first set, where the first and second sets of traces are electrically insulated from and interdigitated respecting one another, and gaps between the first and second sets of traces form boundaries between the first and second sets of traces that undulate and that are not straight or linear. Other embodiments of a mutual capacitance touchscreen are also disclosed, such as 'mini-diamond' sensor array patterns and sensor array patterns that may be manufactured at low cost.
