Single-layer touch sensor

摘要

In one embodiment, a touch sensor includes a first electrode and a second electrode. At least a portion of the second electrode is interdigitated with the first electrode. The first electrode includes a base portion, a digit and an extent. The digit includes a first end and a second end, connects to the base portion at the first end, and extends from the base portion in a first direction along a first axis. The extent connects to the digit at the second end and extends from the digit along a second axis that is substantially perpendicular to the first axis.
