Abstract

A wireless power transmission system includes an electronic device and an array display device. The array display device includes a display surface and an array substrate. The array substrate has a substrate and an array which is disposed at one side of the substrate. The array substrate emits an electric power signal coupled to the electronic device from the display surface. The electronic device manages the electric power signal for operation.
