2. The display device according to claim 1, wherein in response to receiving the second packet, the wireless communication unit to identify the terminal that provides the second packet, and

wherein after the controller determines that the identified terminal corresponds to the at least one registered wake-up device, the power of the display device is turned on.

3. The display device according to claim 2, wherein the information of the at least one registered wake-up device includes a media access control (MAC) address of the at least one registered wake-up device or a Bluetooth device address of the at least one registered wake-up device, and

the wireless communication unit is configured to identify the terminal that provides the second packet based on the MAC address of the terminal or the Bluetooth device address of the terminal, which is provided in the second packet.

4. The display device according to claim 3, wherein the wireless communication unit is configured to identify the terminal that provides the second packet when information of the display device is provided in the second packet.

5. The display device according to claim 1, wherein in response to receiving the second packet, the wireless communication unit to identify a terminal that provides the second packet based on information within the second packet, and the wireless communication unit is to transmit, to the controller, a trigger signal to turn on the power of the display device based on the received second packet.

6. The display device according to claim 1, comprising a power supply to supply power to the display device,

wherein the wireless communication unit is configured to control the power supply to turn on the power of the display device based on the received second packet.

7. The display device according to claim 1, wherein the second packet includes information regarding a specific function of the display device or an application execution request of the display device, and

wherein when the power of the display device is turned on, the controller is to execute the specific function or the application.

8. The display device according to claim 7, comprising a display,

wherein the second packet includes a screen mirroring execution request, and

wherein when the controller receives, from the terminal providing the second packet, image data corresponding to a screen displayed on the terminal when the power of the display device is turned on, the controller is to control the display to display a mirroring screen based on the received image data.

9. The display device according to claim 1, wherein the first packet includes encoding information, and

the wireless communication unit is configured to decode information of the received second packet based on the encoding information and turn on the power of the display device based on the decoded information of the received second packet.

10. The display device according to claim 9, wherein when the wireless communication unit is operating in the wake-up mode, the wireless communication unit is to periodically output the first packet including the encoding information, and

the outputted encoding information is to change each time the first packet is outputted from the wireless communication unit.

11. The display device according to claim 10, wherein the wireless communication unit is configured to decode the received second packet based on a plurality of encoding information within a plurality of first packets.
