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