Abstract
A display device includes a first communication unit connected to one or more peripheral devices, a second communication unit that communicates with a remote controller, and a processor. If the processor is initialized in response to a power-on instruction through the second communication unit, the processor verifies whether a first peripheral device, which is selected as a source device that provides at least one source of video and audio signals, among the one or more peripheral devices is powered on within a first threshold time. If the first peripheral device is not powered on within the first threshold time, the processor transmits a power-on request for allowing the remote controller to power on the first peripheral device, to the remote controller through the second communication unit.
