  • Publication number: 20240393910
    Abstract: A touch screen is disclosed having a length and a height, and comprising interspaced and galvanically isolated first and second arrays of touch pads; wherein the first array of touch pads comprises a plurality of first strings of series-connected touch pads, each first string forming a drive line and extending in a first general direction; wherein the second array of touch pads comprises a plurality of second strings of series-connected touch pads, each second string forming a read line and extending in a second general direction, different to said first general direction; wherein the first general direction and the second general direction are each different from the length direction; and wherein the touch screen is configured for capacitive-based sensing which may be based on a change in a mutual capacitance between individual ones of the drive lines and individual ones of the read lines.

  • Publication number: 20240302918
    Abstract: A touch panel system that includes drivers for providing detection signals on a first plurality of electrodes of a touch panel where each detection signal includes one or more frequency signal components with each frequency signal component having a frequency and a phase offset. The detection signals includes at least three phase offsets for at least one frequency of the frequency signal components. Each detection signal has a unique frequency-phase offset combination of the one or more frequency signal components. The unique combinations allow for the determination of a touch at specific locations on the panel by sensing signals on a second set of electrodes.

  • Publication number: 20240302915
    Abstract: A touch panel includes a first plurality of electrodes and a second plurality of electrodes. A plurality of transmitters generate a plurality of transmit signals by modulating a common sine wave signal with a set of orthogonal modulation signals, and drive each transmit signal onto a corresponding electrode of the first plurality of electrodes. Each transmit signal is generated by modulating the common sine wave signal with a unique orthogonal modulation signal of the set of orthogonal modulation signals. At least two of the plurality of transmit signals are not orthogonal. Each receiver of a plurality of receivers senses a receive signal on a corresponding electrode of the second plurality of electrodes and generates a set of correlation signals by correlating the receive signal with each transmit signal of the plurality of transmit signals. The sets of correlation signals are used to detect a touch event on the touch panel.

  • Patent number: 7801498
    Abstract: A circuit of a system-on-chip for the transmission of an analog signal at a given transmission frequency modulated by a digital input signal coded in a number m of bits, includes 2m?1 unit cells each having a first block adapted to receive an activation voltage through an associated switch, and a second block with a first input path coupled to an output path of the first block, a second input path receiving a local oscillator signal, and an output path coupled to the output path of the circuit, with the switches each controlled as a function of the value of a bit of the digital input signal, the bit of index j of the digital input signal where j is between 0 and m?1, controlling the switches respectively associated with 2j unit cells.
