Abstract
A portable electronic device includes a touch sensing circuit, a substrate, a conductive layer on the substrate, a resistance measuring circuit and a control circuit. The conductive layer includes a plurality of sensing electrodes. The touch sensing circuit determines whether a touch point occurs according to a plurality of capacitance changes of the plurality of sensing electrodes. The resistance measuring circuit measures a resistance value of at least a part of the conductive layer. The control circuit determines whether the touch sensing circuit should enter a correction mode according to the resistance value.
