Abstract
A touch-controlled electronic device with a wireless communication function and a method for reducing wireless signal interference to a touch sensing function are disclosed. The electronic device includes a wireless communication module, a touch sensing module and a synchronous signal interface. By the synchronous signal interface, a synchronous signal is transmitted between the wireless communication module and the touch sensing module and, accordingly, the transmission of the wireless signal is staggered from the timing that receiver electrodes of the touch sensing module receive sensed signals. Thus, wireless signal interference to the touch sensing function of the touch sensing module is suppressed.
