    Abstract: According to an embodiment of the present disclosure, a display device includes a microphone, a wake-up word recognition unit configured to determine whether a voice wake-up word received through the microphone is recognized, and a main processor configured to, when recognition of the voice wake-up word is successful in the wake-up word recognition unit, determine whether the voice wake-up word is a normal wake-up word based on feature information of the voice wake-up word, and, when it is determined that the voice wake-up word is the normal wake-up word, perform a function corresponding to a received speech command as the speech command is received through the microphone.

    Abstract: Disclosed herein is a display apparatus configured to rotate around a fixed axis. The display apparatus includes: a display configured to rotate around the fixed axis and display an image; and a controller configured to process an original image and control the display to display the original image, wherein the original image is stored in a memory or received through wired or wireless communication. The controller is configured to: obtain an output image by processing a central area including an object in the original image to be suitable for a rotation state of the display and a resolution of the display; and control the display to display the obtained output image.

    Abstract: The present invention may provide a display device that automatically configures a remote controller so that an external device connected to the display device can be controlled. According to the present display device, a power control code can be recognized on the basis of a response of a connected external device, and a control code set corresponding to the power control code can be received through a server. When there are a plurality of control code sets corresponding to the power control code, the corresponding control code sets can be received through the server by performing comparison with a user interface included in the video image received from the external device.
