Abstract: A detachable display device includes a main box including a microphone and a main processor, and a display including an amplifier configured to amplify an audio signal received from the main processor and a speaker configured to convert the amplified audio signal into a sound and output the sound. The main processor is configured to perform acoustic echo cancellation (AEC) on the audio signal based on the audio signal output by the main processor, equalization information, and volume information.

Abstract: A display device having a display, a device interface to permit communication with an external device using at least one wireless communication protocol, a network interface for coupling to a network and a controller. The controller is configured to: cause the display to display data mirroring data displayed on an external device; receive a request for playback of content, wherein the request for playback of the content is received from the external device via the device interface; obtain the content from a storage unit when the content is non-streaming content; obtain the content from a source, via the network interface, when the content is streaming content; cause the display to display the content obtained from either the storage unit or the source; and transmit, via the device interface, a first message to the external device to cause the external device to enter a standby mode.

Abstract: Provided is a display device. The display device includes a wireless communication unit configured to transmit/receive a packet according to a wireless communication manner, a storage unit configured to store information of at least one wake-up registration device, and a controller configured to allow the wireless communication unit to operate in a wake-up mode when power of the display device is turned off. The wireless communication unit outputs a first packet including information of the display device as operating in the wake-up mode, receives a second packet corresponding to a response of the outputted first packet, and turns on the power of the display device on the basis of the received second packet.
