[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

Where there is no conflict, embodiments of the present invention and the various features thereof can be combined with each other, all of which are within the scope of protection of the present invention.

[0064] Example 1

[0065] like Figure 1 As shown, this embodiment provides a dynamic display method for an LED rotating ribbon screen. The LED rotating ribbon screen includes a front display screen and a rear display screen arranged opposite to each other. The method includes the following steps:

[0066] S1: Monitors and dynamically displays trigger signals;

[0067] The dynamic display mode of the LED rotating ribbon screen in this embodiment can be activated as needed, specifically by using a trigger signal to control the activation of the dynamic display mode.

[0068] The dynamic display trigger signal can be generated by the sound around the LED rotating ribbon screen.

[0069] For example, when the sound around the rotating LED ribbon screen exceeds a preset decibel level, it indicates that there are many active spectators around the screen. In this case, a dynamic display trigger signal can be generated, causing the LED ribbon screen to start its dynamic display. Besides generating trigger signals based on sound volume, trigger signals can also be generated based on voice commands. For instance, a dynamic display trigger signal can be generated when a spectator issues a voice command that meets the trigger conditions.

[0070] The dynamic display trigger signal can also be generated by the lighting around the LED rotating ribbon screen. For example, a dynamic display trigger signal can be generated when the illuminance around the LED rotating ribbon screen exceeds a preset value.

[0071] The dynamic display trigger signal can also be generated by vibrations around the rotating LED ribbon screen. When the audience around the rotating LED ribbon screen is active, the vibrations generated are also greater. Therefore, in this embodiment, a dynamic display trigger signal can be generated when the detected vibration exceeds a preset value.

[0072] The dynamic display trigger signal can also be generated by the gestures of the audience around the rotating LED ribbon screen. This way, when an audience member's gesture meets preset conditions, the rotating LED ribbon screen can be triggered to start the dynamic display mode.

[0073] S2: After detecting the trigger signal, acquire scene information around the LED rotating ribbon screen, including ambient brightness and audience position distribution;

[0074] The scene information surrounding the LED rotating ribbon screen indicates the environment around the screen. The audience location distribution indicates the number of audience members in different locations around the LED rotating ribbon screen.

[0075] S3: Obtain the display content of the LED rotating ribbon display screen;

[0076] The content displayed on the LED rotating ribbon display screen is pre-selected as needed, and the content includes, but is not limited to, text, images, and videos.

[0077] S4: Determine the display mode based on the display content. The display modes include single-sided area display, single-sided full-screen display, double-sided area display, and double-sided full-screen display.

[0078] This embodiment uses a rotating LED ribbon screen that can display content from both the front and back, providing a relatively long display area on both sides. Therefore, different display modes can be selected as needed. Single-sided area display means that only a portion of the front or back display screen is used to display the content. Single-sided full-screen display means that the entire display area of ​​either the front or back display screen of the rotating LED ribbon screen is used to display the content. Double-sided area display means that a portion of both the front and back display screens of the rotating LED ribbon screen displays the content. Double-sided full-screen display means that the entire display area of ​​both the front and back display screens of the rotating LED ribbon screen displays the content.

[0079] S5: Control the LED rotating ribbon screen to rotate and display the display content according to the scene information, the display mode and the display content.

[0080] This step allows the LED rotating ribbon screen to display the content while rotating, creating a dynamic effect as the display process accompanies the rotation of the LED rotating ribbon screen.

[0081] like Figure 2 As shown, as an optional but advantageous implementation, in this embodiment, S5: controlling the LED rotating ribbon screen to rotate and display the display content according to the scene information, the display mode, and the display content further includes the following steps:

[0082] S51: Obtain the image data to be displayed based on the displayed content;

[0083] The content displayed on an LED display screen can be represented in the form of image data. In this embodiment, image data refers to the data used to represent the displayed content.

[0084] S52: Determine the target rotation angle position and target rotation angle velocity of the LED rotating ribbon screen based on the scene information, the display mode, and the display content;

[0085] This step controls the target rotation angle position and target rotation angular velocity of the LED rotating ribbon screen to make the dynamic display effect of the LED rotating ribbon screen adapt to the scene information, the display mode, and the display content.

[0086] like Figure 3 As shown, as an optional but advantageous implementation, in this embodiment, S52: determining the target rotation angle position and target rotation angular velocity of the LED rotating ribbon screen based on the scene information, the display mode, and the display content further includes the following steps:

[0087] S521: Determine the preferred display location based on the audience location distribution in the scene information;

[0088] When there is only one audience member, that audience member's location is the preferred display location. When there are more than one audience member, the location with the most audience members is the preferred display location. When multiple locations have the same number of audience members, and each location has more audience members than the others, the location closest to the LED ribbon display screen is selected as the preferred display location. In short, the preferred display location is the one that allows the most audience members to easily view the screen.

[0089] S522: Determine the main display area of ​​the LED rotating ribbon screen according to the display mode and the display content;

[0090] If it is a single-sided area display mode, select which part of the display content to display on the front or rear display screen as the main display area.

[0091] If it is a single-sided full-screen display mode, select the area on the front or rear display screen used to display the core content of the display content as the main display area.

[0092] If it is a dual-sided display mode, select the portion of the content displayed on the front screen as the main display area.

[0093] In the dual-sided full-screen display mode, the area on the front display used to display the core content is selected as the main display area. The core content can be manually specified according to display needs.

[0094] S523: Based on the determination of the main display area of ​​the LED rotating ribbon screen and the preferred display position, rotate the main display area to a target rotation angle that faces the preferred display position;

[0095] This step first obtains the target rotation angle as the angle required to rotate the main display area of ​​the LED rotating ribbon screen from its current position to face the preferred display position.

[0096] S524: Determine the target rotation angular velocity of the LED rotating ribbon screen based on the target rotation angle. The target rotation angular velocity includes a first angular velocity and a second angular velocity. The first angular velocity is the angular velocity of the LED rotating ribbon screen rotating from the current angular position to the target rotation angular position. The second angular velocity is the angular velocity of the LED rotating ribbon screen when it continues to rotate from the target angular position.

[0097] S53: Control the rotating ribbon display screen to rotate to the target angular position at the target rotational angular velocity and display the image according to the image data.

[0098] This step involves first rapidly rotating the LED rotating ribbon screen at a first angular velocity until the main display area is directly facing the preferred display position. Then, the LED rotating ribbon screen is slowly rotated at a second angular velocity, allowing viewers in the preferred display position to fully appreciate the display effect. This enables the LED ribbon display screen to provide optimal display based on the scene being depicted.

[0099] like Figure 4 As shown, as an optional but advantageous implementation, the step of controlling the rotating ribbon display screen to rotate to the target angular position at the target rotational angular velocity and displaying the image according to the image data in this embodiment further includes the following steps:

[0100] S531: Obtain the brightness of each light-emitting unit of the LED rotating ribbon screen based on image data;

[0101] The LED rotating ribbon screen uses light-emitting units that emit light at a preset brightness, based on image data. These light-emitting units, acting as individual luminous pixels, form the displayed image. Therefore, the image data determines the brightness of each light-emitting unit.

[0102] S532: Obtain the audience location distribution in the scene information;

[0103] Audience location distribution refers to the number of audience members in each direction represented by the LED rotating display screen.

[0104] S533: Determine the target area in the LED rotating ribbon screen that requires brightness adjustment based on the distribution of audience positions;

[0105] The target area is usually the area directly opposite the rotating LED ribbon screen where the largest number of viewers are located.

[0106] S534: Obtain ambient brightness from scene information;

[0107] Specifically, a light sensor can be selected to detect the brightness of the surrounding environment.

[0108] S535: Adjust the brightness of the light-emitting unit in the target area according to the ambient brightness.

[0109] If the ambient brightness is detected to be high, the brightness of the light-emitting unit will be increased accordingly; if the ambient brightness is detected to be low, the brightness of the light-emitting unit will be decreased accordingly.

[0110] like Figure 5As shown, as an optional but advantageous implementation, the scene information in this embodiment also includes music information played by a multimedia device linked to the LED rotating ribbon screen. Step S52: Determining the target rotation angle position and target rotation angular velocity of the LED rotating ribbon screen based on the scene information, the display mode, and the display content further includes the following steps:

[0111] S521a: Determine the rhythm of the music played in the scene based on the music information in the scene information;

[0112] This embodiment links the background music with the dynamic display of the rotating LED ribbon screen. Specifically, it controls the dynamic display of the rotating LED ribbon screen to match the rhythm of the background music.

[0113] S522a: Determine the target rotational angular velocity of the LED rotating ribbon screen based on the rhythm of the music being played.

[0114] For example, when upbeat and cheerful music is playing in the scene, the faster the tempo of the music, the faster the LED rotating ribbon screen will rotate. Conversely, when soothing and slower music is playing in the scene, the slower the rotation speed of the LED rotating ribbon screen will be.

[0115] This embodiment achieves interaction between the display screen's visual effects and the background music by coordinating the rotation speed of the LED rotating ribbon screen with the rhythm of the music. This enriches the display effects, enhances the fun of the LED rotating ribbon screen interacting with the surrounding scene, and increases its appeal to the audience.

[0116] like Figure 6 As shown, as an optional but advantageous implementation, in this embodiment, the display mode further includes an image shape display mode. When the image shape display mode is used, the display content includes the image to be displayed and the shape of the image. Step S5: Controlling the LED rotating ribbon screen to rotate and display the display content according to the scene information, the display mode, and the display content further includes the following steps:

[0117] S51a: Obtain the external outline of the LED rotating ribbon screen;

[0118] The ribbon display screen is ribbon-shaped, and the shape of the screen varies in different positions.

[0119] S52a: Select the area in the LED rotating ribbon screen whose outer contour is closest to the shape of the image as the target display area based on the shape of the image;

[0120] This step compares the shape of the image to be displayed with various parts of the LED rotating ribbon screen, and selects the part whose outer contour is closest to the shape of the image to be displayed as the target display area.

[0121] S53a: Obtain the displayed image from the displayed content;

[0122] S54a: Control the target display area to display the display image.

[0123] This step displays the image in the target display area selected in the previous steps. Because this embodiment fully utilizes the outer contour of the rotating LED ribbon screen, making the outer contour of the target display area as close as possible to the shape of the image to be displayed, it can present viewers with a seamless visual effect where the image and screen are integrated.

[0124] As an optional but advantageous implementation, in this embodiment, the display mode further includes a target tracking display mode. When the target tracking display mode is used, the display content includes the image to be displayed and the target dynamic image to be tracked, wherein the target dynamic image continuously moves its position on the LED rotating ribbon screen. For example, when the LED rotating ribbon screen displays a ribbon gradually unfolding along the extension direction of the rotating ribbon screen, the image at the front end of the displayed ribbon image is the target dynamic image. As another example, when the LED rotating ribbon screen displays vines growing rapidly along the extension direction of the LED rotating ribbon screen, the image at the front end of the vine growth is the target dynamic image.

[0125] like Figure 7 As shown, step S5: controlling the LED rotating ribbon screen to rotate and display the display content according to the scene information, the display mode, and the display content further includes the following steps:

[0126] S51b: Determine the target viewing location based on the audience location distribution in the scene information;

[0127] This step allows you to select the location with the largest audience as your target viewing location.

[0128] S52b: Determine the starting area for displaying the content on the LED rotating ribbon screen based on the displayed content.

[0129] Generally, the initial position of the target dynamic image when displayed on the LED rotating ribbon screen can be selected as the starting area.

[0130] S53b: Control the LED rotating ribbon screen to rotate until the starting area is directly facing the target viewing position;

[0131] In this embodiment, the starting area of ​​the LED rotating ribbon screen is first aligned with the target viewing position.

[0132] S54b: Obtain the dynamic position of the target dynamic image in the display image when it is displayed on the LED rotating ribbon screen;

[0133] Since the position of the target dynamic image on the LED rotating ribbon screen changes during the display process, this step can obtain the real-time position of the target dynamic image on the LED rotating ribbon screen based on the display content.

[0134] S55b: Control the LED rotating ribbon screen to rotate according to the target viewing position and the dynamic position so that the target dynamic image is facing the target viewing position during the dynamic display process.

[0135] This step involves rotating the LED rotating ribbon screen in conjunction with the display of the target dynamic image, ensuring that the target dynamic image is always positioned comfortably for the viewer at the target viewing location. This allows the viewer to follow the perspective of the target image as it dynamically moves across the screen. Furthermore, the rotation of the LED ribbon screen allows the viewer to perceive the surrounding scene dynamically changing as they follow the target image, thus making the display effect of the rotating screen more vivid.

[0136] Because the curvature of the LED rotating ribbon screen varies at different locations, the density of LED light-emitting units at each location also varies. If the LED rotating ribbon screen rotates at a constant speed, the number of light-emitting units passing through different locations per unit time will differ. Since the light-emitting units are pixels for displaying images, this will create the impression for viewers that the image movement speed is inconsistent. Therefore, as an optional but advantageous implementation in this embodiment, the displayed content includes displayed images, such as... Figure 8 As shown in S5: Controlling the LED rotating ribbon screen to rotate and display the display content according to the scene information, the display mode, and the display content further includes the following steps:

[0137] S51c: Determine the target viewing location based on the audience location distribution in the scene information;

[0138] This step allows you to select the location with the largest audience as your target viewing location.

[0139] S52c: Determine the target display area for the LED rotating ribbon display screen to display the content based on the content being displayed.

[0140] The target display area is the area within the LED rotating ribbon screen where the displayed image is located.

[0141] S53c: Obtain the curvature of each position in the target display area on the LED rotating ribbon screen;

[0142] The curvature of each position of the LED rotating ribbon screen can be detected in advance, and then the curvature of each position of the target display area can be obtained accordingly.

[0143] S54c: Determine the density of LED light-emitting units at each position of the target display area based on the curvature of each position on the LED rotating ribbon screen;

[0144] The density of LED light-emitting units refers to the number of light-emitting units per unit area. The correspondence between various curvatures and the density of LED light-emitting units can be pre-established, and then the density of LED light-emitting units corresponding to the curvature at each position can be found using this correspondence.

[0145] S55c: Determine the rotational angular velocity of each position in the target display area of ​​the LED rotating ribbon screen as it passes the target viewing position based on the density of the LED light-emitting units at each position in the target display area;

[0146] S56c: Control the LED rotating ribbon screen to display the content and rotate at the rotational angular velocity so that each position of the target display area passes through the target viewing position in sequence.

[0147] When a region with high curvature in the target display area passes the target viewing position, the rotational angular velocity can be slowed down to prevent an increase in the number of light-emitting units passing the target viewing position per unit time. Conversely, when a region with low curvature in the target display area passes the target viewing position, the rotational angular velocity can be increased to prevent an insufficient number of light-emitting units passing the target viewing position per unit time. Using the aforementioned control method can improve the situation where image movement is inconsistent in speed.

[0148] In one preferred embodiment, the rotational angular velocity of each position in the target display area as it passes the target viewing position is inversely proportional to the density of the LED light-emitting units at each position. Let the density of the LED light-emitting units be M, and the rotational angular velocity be V, then V = k / M, where the coefficient k is a real number and can be set empirically. By employing the aforementioned control method, the image movement speed (the number of light-emitting units passing through per unit time) of each position in the target display area as it sequentially passes the target viewing position is the same, thereby further improving the display effect of the LED rotating ribbon screen.

[0149] Example 2

The ribbon screen 1 is mounted on the rotating base 2. The control circuit is electrically connected to the ribbon screen 1 and the rotating base 2 respectively. The control circuit includes at least one processor, at least one memory, and computer program instructions stored in the memory. When the computer program instructions are executed by the processor, the method described in Embodiment 1 is implemented.

[0151] The rotating base 2 includes a drive motor, a reduction mechanism, and a main body. The ribbon screen 1 is mounted on the main body. The output end of the drive motor is connected to the input end of the reduction mechanism, and the output end of the reduction mechanism is connected to the main body. The reduction mechanism can be a planetary gear reduction mechanism to increase the transmission ratio.
