Abstract
Provided is a display device including a display, a speaker, a communicator comprising communication circuitry configured to perform wireless communication, a memory configured to store one or more instructions, and a controller including at least one processor configured to execute at least one of the one or more instructions. Based on a wireless connection request for audio transmission being received from an external device while the display device is in a power-off state, the communicator is further configured to transmit, to the external device, a response indicating acceptance of the wireless connection request, and to operate to wake up the controller to a state requiring wireless connection.
