Abstract
Touch sensor panels/screens can include negative temperature coefficient materials in the stack-up and routing traces with expanded areas to reduce thermal drift and minimize the detection of false touches. In some examples, the touch sensor panels/screens can include a plurality of touch electrodes in a first layer. In some examples, the sensor panels/screens can include one or more dielectric materials in a second layer, the one or more dielectric materials including a negative temperature coefficient material. In some examples, the touch sensor panels/screens can include a plurality of routing traces in a third layer, the plurality of routing traces routing the plurality of touch electrodes to a touch controller chip.
