    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 analyzing 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.

    Abstract: A touch surface includes an array of rows of electrodes, an input point on a row for injecting an input voltage (VDRIVE), measuring an output voltage (VSENSE) at a second point in the row, p being the number of pitch spacings of the array separating the two points, the portion of the array between the first point and the second point being akin to an electric dipole of resistance (R(p)) and of capacitance (C), the output voltage (VSENSE) being equal to the product of the input voltage (VDRIVE) and a transfer function represented by a complex function (HSENSE). The measurement includes extracting the amplitude (G) and the phase (φ) from the transfer function; and calculating a hybrid function (S(G, φ)) of the amplitude and of the phase, the hybrid function minimizing a sum (Σ) defined by Σ i ∈ [ 0 , p ] ⁡ ( δ ⁢ ⁢ S δ ⁢ ⁢ R ⁢ ( G ⁡ ( R i ) , φ ⁡ ( R i ) ) ) .

    Abstract: The general field of the invention is that of touchscreen devices with projected capacitive detection comprising a touch-sensitive matrix panel comprising a plurality of conductive rows and conductive columns, said panel being connected to electronic control means. The electronic control means generate two periodic transmission voltages transmitted at two different frequencies. Analysis of the reception voltages is used to determine the positions of presses on the touch-sensitive panel, including when a row or column is cut. Pressing on a cut row or column is basically determined by calculating the barycenters of ‘virtual’ hollows in the reception voltages corresponding to this cut row or column.
