Abstract

Disclosed is a touch sensitive display apparatus comprising a sensor comprising an input array of electrodes and, capacitively coupled thereto, an output array of electrodes. The apparatus also comprises a plurality of reception circuits (for example three), each reception circuit being operable to simultaneously receive a signal from a different electrode of said output array of electrodes. The reception circuits each comprise an analogue to digital converter.
