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.

Abstract: A display device includes a first communication interface which is communicatively connected with a source device, a second communication interface that communicates with a remote control device, and a processor configured to identify whether a first signal is received from the source device when a power-on signal of the display device is received from the display device, to identify whether the first signal includes a specified image when the first signal is received from the source device, and to transmit a power-on request signal of the source device via the first communication interface or the second communication interface when the first signal is not received from the source device or when the first signal includes an image.
