Abstract: An input device having an anti-static layer coupled to a grounding element such as a cellphone bottom chassis via a current hindering circuit having a resistive circuit element. Without the current hindering circuit having a resistive circuit element, a large amount of the current from an input object would flow through the connection to the grounding element and would not flow to a receiver channel for processing. This decreases the signal strength within the receiver channel, making sensing more difficult to perform. However, with the current hindering circuit having a resistive circuit element, current is hindered from flowing to ground and thus flows to the receiver channel, thereby increasing the signal strength. The current hindering circuit having a resistive circuit element may be a resistor or a Zener diode that is directed to prevent current flow from the anti-static layer to the grounding element until a significant voltage has built up across the Zener diode.

The touch status indicates presence or absence of one of the objects in the selected cell.
