Title:
PRODUCING CAPACITIVE IMAGES COMPRISING NON-CONNECTION VALUES
Document Type and Number:
WIPO Patent Application WO/2012/012299
Kind Code:
A3
Abstract:
Apparatus and method for producing capacitive images of a sensing region of a sensor electrode are disclosed. The sensor electrode comprises a plurality of connection sections and a non-connection section. The sensor electrode is connected to sensor circuitry at a plurality of connection locations located in the plurality of connection sections and not the non-connection section. The apparatus is operated by transmitting a transmitter signal into the sensor electrode at a connection location of the plurality of connection locations, receiving a plurality of resulting signals from the sensor electrode at multiple connection locations of the plurality of connection locations, and producing a capacitive image using the plurality of resulting signals. The plurality of resulting signals includes effects of the transmitter signal propagating through the sensor electrode to the multiple connection locations. The capacitive image comprising a non-connection value associated with the non-connection section.
