Abstract

A display device ( 1 ), a container system, and a method for controlling the display device ( 1 ) are provided. The display device ( 1 ) includes: a display screen ( 10 ) including a display surface ( 101 ) and a back surface ( 102 ) opposite to the display surface ( 101 ); a depth camera component ( 11 ) configured to obtain image information in front of the display screen ( 10 ) in real time, the image information including distance information between a user and the display screen; and a processing component ( 12 ) electrically connected to the depth camera component ( 11 ) and configured to control switching of display content and/or format of the display screen ( 10 ) according to the distance information between the user and the display screen ( 10 ) determined by means of the obtained image information.

First claim

The invention claimed is:

1. A display device, comprising:
a display screen, comprising a display surface and a back surface opposite to the display surface;
a depth photographing component, configured to acquire image information in front of the display screen in real time, wherein the image information contains distance information between a user and the display screen; and
a processing component, electrically connected to the depth photographing component and configured to control display contents and/or formats switching of the display screen according to the distance information between the user and the display screen determined by the acquired image information, wherein:
the display device further comprises a microphone component and a photoelectric sensing component;
the photoelectric sensing component is a sensing control switch of the microphone component, the microphone component is turned on through a gesture sensed by the photoelectric sensing component, the photoelectric sensing component and the microphone component are assembled integrally at a close distance;
the display device further comprises a first photographing component, configured to acquire user image information in real time;
the display device further comprises an assembly support frame fixed on a side of the display screen;
an extension direction of a main body of the assembly support frame is the same as an extension direction of a side edge fixed on the display screen, and the assembly support frame comprises a first through groove, a second through groove and a third through groove arranged sequentially along the extension direction of the main body of the assembly support frame;
the first photographing component is embedded in the first through groove to be fixed with the display screen; the photoelectric sensing component is embedded in the second through groove to be fixed with the display screen; and the microphone component is embedded in the third through groove to be fixed with the display screen; and
the processing component is disposed at a lower side of the display screen, a power supply is disposed at a same side as the processing component, the power supply and the processing component are disposed at the lower side of the display screen.

2. The display device according to claim 1 , wherein the processing component is configured to:
control the display screen to display different advertisement images sequentially when a distance between the user and the display screen is determined to be greater than a first distance value; and
control the display screen to display a first display image including commodity information in a container and prompting selection of goods information when the distance between user and the display screen is determined to be less than the first distance value.

3. The display device according to claim 2 , wherein
the photoelectric sensing component is configured to sense human body action information in real time;
the microphone component is configured to receive voice information of the user when receiving a first instruction; and
the processing component is further configured to, when the human body action information sensed by the photoelectric sensing component is acquired, send the first instruction to the microphone component, acquire voice information of the microphone component, and control the display screen to display a second display image including an goods information introduction corresponding to the voice information.

4. The display device according to claim 2 , wherein the processing component is further configured to count a quantity of viewers and a duration of stay of the viewers during a display period of a corresponding advertising image when the distance between the user and the display screen is determined to be greater than the first distance value and less than the second distance value.

5. The display device according to claim 4 , wherein the processing component is configured to:
read the quantity of human body contours in a range of a distance from the display screen which is larger than the first distance value and smaller than the second distance value before the display period of the current advertisement image;
increase the quantity of human body contours by one when a human body contour is determined to be moved into a range of the second distance value during the display period of the current advertisement image; and
reduce the quantity of human body contours by one when a human body contour is determined to be moved out of the range of the second distance value during the display period of the current advertisement image.

6. The display device according to claim 1 , wherein the photoelectric sensing component comprises a plurality of first lugs on a side away from the display surface, and the microphone component comprises a plurality of second lugs on a side away from the display surface;
the assembly support frame comprises a plurality of first grooves on a side away from the display surface, the assembly support frame comprises a plurality of second grooves on the side away from the display surface, and the first lugs are embedded in the first grooves one by one to limit the photoelectric sensing component; and the second lugs are embedded in the second grooves one by one to limit the microphone component.

7. The display device according to claim 6 , further comprising a protective cover plate located on a side of the assembly support frame away from the display surface, and a buffer double-sided thermal conductive adhesive located between the assembly support frame and the protective cover plate, wherein the protective cover plate and the buffer double-sided thermal conductive adhesive are fixed to the assembly support frame through an assembly component.

8. The display device according to claim 6 , further comprising a first photographing cover plate covering a photographing surface of the first photographing component, and a first photographing double-sided buffer adhesive located between the first photographing component and the first photographing cover plate, wherein the first photographing double-sided buffer adhesive comprises a hollow in a region corresponding to the first photographing component.

9. The display device according to claim 1 , wherein:
the display screen is used for being arranged on a door body or directly acting as the door body; the display device comprises at least one second photographing component arranged on the back surface and a first sensor;
the first sensor is configured to detect an opening angle of the display screen relative to the door body of the container in real time;
the second photographing component is configured to photograph goods in the container when a photographing instruction is received; and
the processing component is further configured to acquire an opening angle of a door body of the first sensor, and send the photographing instruction to the second photographing component when the opening angle of the door body is determined to be a first angle.
