1. A method for transmitting and detecting touch sensing signals in a touch device having a set of parallel conducting lines, said method comprising:

  • providing a work signal to a selected portion of the conducting lines that serve as touch sensing lines and that cooperate to define a touch sensing area;

    providing, by a touch sensor circuit electrically coupled to each of the touch sensing lines, a touch sensing signal to the touch sensing lines;

    wherein, for each of the touch sensing lines, the work signal is provided during a first time interval and the touch sensing signal is provided during a second time interval; and

    detecting the touch sensing lines to obtain a detecting signal that corresponds to the touch sensing signal and that indicates occurrence of a touch event, so as to determine at least one of a position and an intensity of the touch event.
