<P>PROBLEM TO BE SOLVED: To provide a wireless charging device and a wireless charging system which can simultaneously perform charging and data transmission in parallel by only putting an electronic device within the electric power transmittable distance of the charging device without cable connection and which are highly convenient by eliminating complexity of preparing separate chargers. <P>SOLUTION: A wireless charging system comprises a power supply device 40 capable of supplying electric power wirelessly and a display device 22. The power supply device 40 includes an electric power generation unit 44 for generating electric power to be supplied, a power transmission element part 41 for transmitting electric power generated by the electric power generation unit; and wireless communication units 450 and 460 capable of transmitting and receiving data wirelessly. The display device is capable of displaying at least either of data transferred by a charging target device and received through the wireless communication units or information about a charging state received as a response to electric power transmitted for charging. <P>COPYRIGHT: (C)2012,JPO&INPIT |
