Abstract
A wiring harness and a touch sensor incorporating same are disclosed. The touch sensor includes a sensing electrode disposed in a touch sensitive area. The touch sensor further includes a plurality of auxiliary electrodes disposed on a self-supporting dielectric substrate in a border area. The auxiliary electrodes transmit a touch signal to electronics configured to use the touch signal to determine the touch location.
Claims36
A touch sensor comprising:
- a sensor substrate covering a touch sensitive area, the touch sensitive area configured to receive a touch input applied to the touch sensitive area from a front side of the touch sensor;
- a sensing electrode disposed on the sensor substrate in the touch sensitive area;
- a self-supporting dielectric substrate covering a border area, the border area being outside the touch sensitive area the dielectric substrate being disposed between the sensing electrode and the front side of the touch sensor;
- and
- a plurality of auxiliary electrodes disposed on the self-supporting dielectric substrate in the border area, the auxiliary electrodes being capacity coupled to the sensing electrode, the touch sensor generating a touch signal in the sensing electrode in response to the touch input applied to the touch sensitive area front the front side of the touch sensor, the auxiliary electrodes transmitting the touch signal to electronics configured to use the touch signal to determine the touch location.
