Abstract: A device with touch surface with projected capacitive detection comprising a matrix touchscreen comprises a plurality of conductive rows and of conductive columns, the screen linked to electronic control means generating, for each conductive row and for each conductive column, transmission signals and electronic means for receiving and analysing the reception signals from each conductive row and from each conductive column. Each row of the device comprises, at one of its ends, first means for generating a first transmission signal and first means for receiving a first reception signal and, at its opposite end, second means for generating a second transmission signal and second means for receiving a second reception signal, the first transmission signal and the second transmission signal being synchronous, having the same frequency, the same amplitude and the same phase.
