Abstract
A touch detection circuit includes a plurality of driving signal generators. The driving signal generators are divided into a plurality of driving signal generator groups, and each of the driving signal generator groups comprises at least one of the driving signal generators. The driving signal generators respectively generate a plurality of driving signals, and a frequency of each of the driving signals in one of the driving signal generator groups is different from a frequency of each of the driving signals in another one of the driving signal generator groups.
