Claim Text:
1. A clustered scan method of a capacitive touch device with n drive lines and m sense lines, the method comprising steps of: simultaneously driving multiple drive lines selected from the n drive lines in a driving cycle, wherein the multiple drive lines include the drive lines of a (i−j) incrementing i by one and resuming the step of simultaneously driving the multiple drive lines; wherein i is a positive integer between 1 and n, and j and k are zero or positive integers, each of the multiple drive lines is driven by a driving signal, and a sum of all the driving signals in the driving cycle is greater than zero; when a number of the multiple drive lines simultaneously driven in the driving cycle is odd, k and j are equal positive integers; wherein when (i−j) is less than 1, the first drive line is driven only or the first drive line to the (i+k) when (i+k) is greater than n, the (i−j)
