    摘要: A touch method, a touch circuit and a touch device are provided. The touch method includes: in an ath touch time period, providing a touch driving signal to an ath touch driving electrode; wherein a is a positive integer, a is less than or equal to A, and A is a positive integer; in an ath background data detection time period, providing a touch accompanying signal to N touch driving electrodes adjacent to the ath touch driving electrode; wherein N is a positive integer; and performing touch detection according to an ath touch sensing signal on touch sensing electrodes in the ath touch time period and an ath background data voltage signal on the touch sensing electrodes in the ath background data detection time period; wherein an amplitude of the touch accompanying signal is less than an amplitude of the touch driving signal.
