Abstract
There is provided a capacitive sensing system including multiple sensor electrodes, an insulating layer and a single active shielding metal. The single active shielding metal has an overlapped region with each of the multiple sensor electrodes. The insulating layer is arranged between the single active shielding metal and the multiple sensor electrodes. When one of the multiple sensor electrodes is driven by a driving signal, the rest of the multiple sensor electrodes are grounded or receive an active shielding signal, and the single active shielding metal receives the active shielding signal.
