Abstract
A clustered scan method of a capacitive touch device has steps of simultaneously providing driving signals in one driving cycle to multiple driving lines including the (i−j)drive line to the (i+k)drive line, and simultaneously providing driving signals in a next driving cycle to the drive lines including some of the drive lines driven in the previous driving cycle with a sum of the driving signal in each driving cycle greater than zero. When the stimulated drive lines include a bordering drive line, the driving lines are determined according to a relationship among i, j and k. Accordingly, the signal to noise ratio of the touch device can be increased and the adverse effect for common ground occurring between a measuring system and a human body can be reduced so that the multi-finger positioning issue can be resolved.
