That is, when the information data includes a plurality of first images having the same size as the first display screen 26 (i.e., the aspect ratio of the first images is substantially the same as the aspect ratio of the first display screen 26), the plurality of first images are in one-to-one correspondence with the plurality of rotation modules 20, and all the first display screens 26 on each rotation module 20 display the corresponding first images.

For convenience of description, taking the case that the rotary display screen is provided with three rotary modules 20, the mounting frame 21 of each rotary module 20 is provided with three mounting sides, each mounting side is provided with one first display screen 26, and the aspect ratio (height: width) of each first display screen 26 is 1:1 as an example, when the received information data includes three first images, if the aspect ratio (height: width) of each first image is 1:1 or is close to 1:1, each first image is correspondingly arranged on the display screen of one rotary module 20, and the corresponding first images are independently displayed on the respective first display screens 26 of the rotary modules 20, at this time, the rotary modules 20 are rotated, so that the first display screens 26 of any two adjacent rotary modules 20 are staggered (refer to fig. 2), and at this time, the matching information between the display positions on the two adjacent rotary modules 20 is irrelevant, or the first display screens 26 of the rotary modules 20 are rotated, so that the first display screens 26 of any two adjacent rotary modules 20 are aligned one by one (refer to fig. 1). Of course, it is also possible to have all the first display screens 26 display the same first image. The first image may be a picture or a video.

In some embodiments, the information data includes a second image, the second image having a height greater than the height of the first display screen 26 and an integral multiple of the height of the first display screen 26, the second image being divided in a height direction thereof to form a plurality of image units, each image unit having a size identical to the size of the first display screen 26; and sequentially arranging a plurality of image units of the second image on the first display screens 26 of the plurality of rotating modules 20 from top to bottom, and rotating the corresponding rotating modules 20 according to the matching information of the plurality of image units of the second image and the position information of each rotating module 20 until the first display screens 26 displaying the corresponding image units are aligned on the plurality of rotating modules 20, so that the first display screens 26 of the plurality of rotating modules 20 jointly display the corresponding second image.

Likewise, for convenience of description, the rotary display screen is provided with three rotary modules 20, the mounting frame 21 of each rotary module 20 is provided with three mounting sides, each mounting side is provided with one first display screen 26, the aspect ratio (height: width) of each second image is 3:1 or is close to 3:1, when the received information data includes three second images, each second image is divided into three matched upper, middle and lower image units (the three image units can be marked and marked data are stored) from top to bottom, the upper image unit is arranged on one first display screen 26 of the upper rotary module 20, the middle image unit is arranged on one first display screen 26 of the middle rotary module 20, the lower image unit is arranged on one first display screen 26 of the lower rotary module 20, and according to the position of each image unit on the rotary module and the position of the rotary module, the first display screen 26 of each rotary module 20 is rotated, so that the first display screens 26 provided with the associated second images in each rotary module 20 are aligned one by one (the position of the two adjacent rotary modules 20 can be matched with each other) and the two other images can be displayed by referring to the position of the first display screen 20 and the other two identical side of the first display module. Thus, three long second images can be displayed by rotating the display screen. Of course, it is also possible to have each side of the rotary display screen display the same second image.

Since each rotary module 20 can rotate independently, a picture can be displayed by the first display screens 26 of some rotary modules 20, and the first display screens 26 of the other rotary modules 20 can display pictures independently, so that the display flexibility is high. Wherein the first image and the second image may be video data or picture data.

In some embodiments, when the information data includes at least one first image(s) and at least one second image(s), the second images are displayed on the rotary display screen according to the display method of the second images until all the second images are displayed on the rotary display screen, then it is determined whether the idle first display screen 26 is still present on the rotary display screen, if the idle first display screen 26 is present, the first images are displayed on the idle first display screen 26 according to the display method of the first images until all the first display screens 26 display images. If the first display screen 26 which is idle does not exist, the first image and the second image are alternately displayed in sequence according to the preset display time. Therefore, the rotary display screen can be fully utilized for displaying.

In some embodiments, when the information data includes the first image and the second image, the first image and the second image are alternately displayed in sequence according to a preset presentation time. In this way, in the process of switching the first image and the second image, the rotating module 20 can be made to rotate, which is beneficial to attracting the attention of tourists, so that the display effect can be improved.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
