Abstract: Elements are provided that mitigate the effects of at least one of charger noise, display noise, and non-grounding in a capacitive touch panel system. Such elements may include an array of sense lines made up of sense electrodes that are shaped differently from drive electrodes making up an array of drive lines, where the area occupied by the sense electrodes is substantially less than that taken up by the drive electrodes. Additionally, the shape of the sense electrodes, despite mitigating the aforementioned effects of charger noise, display noise, and non-grounding, maintains touch detection sensitivity.

Abstract: According to an exemplary implementation, a touch sensor includes a plurality of traces situated between first and second columns of transmitter pads on a substrate. Each trace in the plurality of traces is routed from one extremity of the substrate and ends at a corresponding transmitter pad thereby creating an available area between the first and second columns of transmitter pads for one or more remaining traces of the plurality of traces. In some implementations, for at least one trace in the plurality of traces, each of the one or more remaining traces have an expanded width in the available area. Furthermore, at least one dummy pad can be situated in the available area for at least one trace in the plurality of traces.
