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.
Claims26
A touch sensor comprising:
- a plurality of traces situated between first and second columns of transmitter pads on a substrate;
- each trace in said plurality of traces being routed from one extremity of said substrate and ending at a corresponding transmitter pad thereby creating an available area between said first and second columns of transmitter pads for one or more remaining traces of said plurality of traces.
A touch sensor comprising:
- a terminating trace and one or more remaining traces situated between first and second columns of transmitter pads on a substrate;
- said terminating trace being routed from one extremity of said substrate and ending at a corresponding transmitter pad thereby creating an available area between said first and second columns of transmitter pads;
- wherein each of said one or more remaining traces have an expanded width provided by said available area.
A touch sensor comprising:
- first and second pluralities of traces situated between first and second columns of transmitter pads on a substrate;
- each trace in said first plurality of traces being routed from one extremity of said substrate and ending at a corresponding upper transmitter pad;
- each trace in said second plurality of traces being routed from another extremity of said substrate and ending at a corresponding lower transmitter pad.
A touch sensor comprising:
- a combined trace routed from one extremity of a substrate to another extremity of said substrate;
- a first plurality of traces situated between first and second columns of transmitter pads on said substrate;
- a second plurality of traces situated between said second column of transmitter pads and a third column of transmitter pads on said substrate;
- each trace in said first and second plurality of traces being routed from said another extremity of said substrate and ending at a corresponding transmitter pad;
- wherein at least one of said first plurality of traces and at least one of said second plurality of traces are coupled into said combined trace at said another extremity of said substrate.
