PROBLEM TO BE SOLVED: To provide an electronic device, a noncontact power transmission system, and the like capable of appropriately executing display rewrite of a display unit at arbitrary rewrite request timing.SOLUTION: An electronic device includes: a power receiving unit 10 receiving electric power over noncontact power transmission; a circuit device 90; a display unit 150; a processing unit 120 exerting a display control over the display unit 150; and a receiving unit 122 receiving a display rewrite request for the display unit 150. The circuit device 90 controls a charge accumulation unit 92 to accumulate electric charge, and determines whether the charge accumulation unit 92 accumulates the charge by as much as a charge amount necessary to rewrite display of the display unit 150 at write request timing identified by the display rewrite request and a charge amount necessary for power consumption before the rewrite request timing. The processing unit 120 performs a display rewrite process on the display unit 150 at the rewrite request timing. |
