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. | 04-07-2011 |
