Abstract

A display device includes a display, a wireless charging coil, a wireless charging control module, and a wireless communications module. When the wireless charging control module detects an external device which matches with the wireless charging control module through the wireless charging coil, the wireless charging control module obtains a charging specification of the external device by exchanging messages with the external device through the wireless charging coil, and the wireless charging control module transmits the connection information of the wireless communications module to the external device through the wireless charging coil. The external device establishes a wireless connection to the wireless communications module according to the connection information.
