Abstract:
A method for transmitting and detecting touch sensing signals in a touch device having a set of parallel conducting lines includes: providing a work signal and a touch sensing signal to a selected portion of the conducting lines that serve as touch sensing lines and that cooperate to define a touch sensing area; 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. 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.
