Abstract
A sensing device includes a substrate, a sensing component and a shielding device. The sensing component is configured to detect a touch capacitance in response to a touch event on the sensing device. The shielding device, between the substrate and the sensing component, is configured to distribute electrical energy, and shield the substrate from the sensing component.
