    Abstract: A control method for a display device includes: receiving a user distance, and determining whether the user distance is smaller than a preset distance: if so, transmitting a first control command to a display screen to control the display screen to enter a local display state, and a second control command to a player to control the player to output local image data; receiving the local image data; and transmitting the local image data to the display screen. The user distance is a distance from the user to a reference surface in a direction perpendicular to the reference surface, and the reference surface is a display surface of the display screen or a plane parallel to the display surface. The preset distance is a minimum distance from the user to the reference surface in a case where the field of view of the user covers the entire active area.
