Display device and operating method thereof

A display device, comprising:

• at least one speaker;
• a moveable display configured to be moved from a first position to a second position, wherein the display has a first spatial physical relationship with the at least one speaker at the first position and has a second spatial physical relationship with the at least one speaker at the second position;
• and
• a processor configured to:
• output audio from the at least one speaker, when the display is in the first position,
• receive an information signal indicating the display has been moved to the second position from the first position, and
• change the output of the audio from the at least one speaker based on the second spatial physical relationship,
• wherein a spatial physical relationship between the display and the at least one speaker includes an overlapped spatial physical relationship in which an output direction of audio output by the at least one speaker overlaps with the display and a distance between the display and the at least one speaker, and
• wherein the processor is configured to define an operational mode of the display based on the spatial physical relationship between the display and the at least one speaker.
