Abstract
A mutually capacitive touch sensor includes a first capacitor electrode and a second capacitor electrode. The second capacitor electrode is adjacent and spatially separated from the first capacitor electrode. An inner region is disposed between the first capacitor electrode and the second capacitor electrode, wherein the first capacitor electrode and the second capacitor electrode are arranged to surround the inner region. The inner region may include a hole for a backlight.
