Abstract

A capacitive touch panel includes a first substrate and a second substrate arranged relative to the first substrate. A plurality of drive electrodes are arranged on the first substrate, wherein each drive electrode comprises a first drive electrode section and a second drive electrode section. In addition, a plurality of sense electrodes are arranged on the second substrate, the plurality of sense electrodes including touch sensing electrodes and force sensing electrodes. At least part of a sense electrode of the plurality of sense electrodes forms a force sensitive coupling capacitance with a second drive electrode section and not with a first drive electrode section.
