Abstract
Row conductors have enhanced sensitivity by having more than one transmitter connected to each of the row conductors. Each of the transmitters can transmit a different signal on more than one of the row conductors. Row groups can be formed by having one of the signals transmitted on a plurality of row conductors, while other signals are also transmitted on the row conductors. This can increase the sensitivity area for a sensor device and further noise present on the sensor device.
Claims20
A sensor device, comprising:
- a plurality of first conductors;
- a plurality of second conductors positioned in proximity to the plurality of first conductors such that a touch event proximate to the sensor device causes a change in coupling between at least one of the plurality of first conductors and at least one of the plurality of second conductors;
- and
- a plurality of transmitters operably connected to each one of the plurality of first conductors, wherein each of the transmitters is adapted to transmit a unique orthogonal signal with respect to each other unique orthogonal transmitted by each one of the plurality of transmitters, wherein at least one of the plurality of transmitters is connected to at least two of the plurality of first conductors and the unique orthogonal signal is transmitted simultaneously on the at least two of the plurality of first conductors.
