A rotary connector module for displays has at least one stem and rotor parts. A rotary rotation system containing a stator part base is disposed atop a winding and a magnetic system of the rotor part, the magnetic system disposed above or outside of primary and secondary winding members. An electrical power transmitter carries wireless electrical power from stem to rotor part, with the diameter of each stem or rotor part smaller than the diameter of the magnetic system. A wireless transmission system contains a hollow shaft disposed in the at least one rotor part, an at least one signal transmitter disposed on the at least one stator part, and an at least one signal receiver disposed on the at least one rotor part, with the signal receiver at the end of and below a base of the hollow shaft.
