Abstract
A capacitive touch panel includes elongated drive electrodes arranged next to one another and elongated sensor electrodes arranged next to one another across the drive electrodes. Together, the drive electrodes and the sensor electrodes define a coordinate system where each coordinate location comprises a capacitor formed at an intersection between one of the drive electrodes and one of the sensor electrodes. In implementations, the drive electrodes and/or the sensor electrodes are configured to block capacitance between a touch at a coordinate location and the drive electrodes during a floating condition for the panel. In other implementations, the drive electrodes and/or the sensor electrodes are configured to exaggerate capacitance between a touch at a coordinate location and the drive electrodes during a floating condition for the panel.
