  • Patent number: 8884911
    Abstract: A resistive touch controlling system includes a first sensing module, a second sensing module and a processing circuit. The first sensing module includes a plurality of sensing line groups. The processing circuit is electrically coupled to the first sensing module and the second sensing modules. When the first sensing module senses at least two touch points, the processing circuit takes a combination of touch points sensed by the first and second sensing modules as a first candidate list. After that, the processing circuit turns off some of the sensing line groups of the first sensing module sensing one of the sensed touch points, and takes a touch point(s) sensed by the first sensing module and the second sensing module as the second candidate list. Finally, the processing circuit compares the first candidate list with the second candidate list to determine a current touch sensing result.
