[0002] As disclosed in the patent with the application number 202323441815.7, a liftable annular LED large screen includes an annular LED large screen assembly and a guiding assembly. The annular LED large screen assembly is arranged on the main stage. The annular LED large screen assembly can move up and down along the height direction of the main stage through a driving mechanism. The annular LED large screen assembly includes an annular LED large screen body and a mounting frame. The annular LED large screen body is spliced by a plurality of arc-shaped LED screens. The mounting frame is arranged in an arc shape. The inner side wall of the mounting frame is attached to the installation surface of the annular LED large screen body. The annular LED large screen body is fixed to the mounting frame. Through the arranged driving mechanism, sling assembly and guiding assembly, the annular LED large screen assembly can be stably lifted, and thus the height of the screen can be adjusted in real time according to the stage design requirements, thereby effectively improving the display effect of the stage.

[0003] However, the above solution has the following defects: a plurality of LED screens are all fixed on the same mounting frame, the distance between the LED screens is fixed, and the imaging effect of the performance shown is single; whether it is to cooperate with the performance or to repair and replace the LED screen, the entire LED large screen needs to be lifted, which is rather troublesome.

The moving trajectories of the two corresponding left and right LED screens are concentric. At least two left LED screen assemblies or / and right LED screen assemblies are provided. One of the adjacent two LED screens in the left LED screen assembly or / and right LED screen assembly is located on the circumferential inner side of the other LED screen.

[0006] Multiple LED screens can be independently controlled, providing higher flexibility and creativity.

Through the above settings, the two LED screens in the middle can form a continuous display picture.

[0012] Preferably, when two adjacent LED screens of the left LED screen assembly or the right LED screen assembly move away from each other, the end of one of the two adjacent LED screens is directly in front of the end of the other LED screen. Through the above settings, the neat arrangement of the screen can be maintained, ensuring that the audience in front of the LED screen can see the display picture.

[0013] Preferably, the arc length of one of the adjacent two LED screens in the left LED screen assembly or the right LED screen assembly is greater than that of the other LED screen. Through the above settings, different visual effects can be created and different stage layouts can be adapted.

[0024] The present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] As shown by Figure 1 , Figure 2 , Figure 7 and Figure 8 , this embodiment discloses a combined LED screen system, which includes three left LED screen assemblies 110 on the left side and three right LED screen assemblies 120 on the right side. Each left LED screen assembly 110 and right LED screen assembly 120 includes a walking track 1, a movable frame 2, and an LED screen 3 which is arranged on the lower side of the movable frame 2 and is arc-shaped. A walking driver 21 for moving the movable frame 2 along the extending direction of the walking track 1 is provided at the movable frame 2, and a lifting driver 22 for lifting the LED screen 3 is also provided at the movable frame 2. Among them, the LED screens 3 of the three left LED screen assemblies 110 in this embodiment are the first left LED screen 111, the second left LED screen 112, and the third left LED screen 113 respectively, and the LED screens of the three right LED screen assemblies 120 are the first right LED screen 121, the second right LED screen 122, and the third right LED screen 123 respectively. Among them, the arc length of the second left LED screen 112 in this embodiment is greater than the arc lengths of the first left LED screen 111 and the third left LED screen 113.

[0026] The height and left-right position of all the LED screens 3 can be adjusted according to actual needs, so as to obtain arrangement effects including but not limited to Figures 3 to 6 as shown. Figure 3 and Figure 6 are schematic diagrams of the combined LED screen that can be seen by the audience sitting in front of the LED screen.

[0027] The walking track 1 in this embodiment is fixed on the theater building structure. Adjacent walking tracks 1 are independent of each other and not connected. The movement between the movable frame 2 and the walking track 1 is realized through the interaction force between the walking driver 21 and the walking track 1. The walking driver 21 uses a walking motor, and the lifting driver 22 uses a winch and is equipped with a pulley assembly. Each LED screen 3 can correspond to independent screen section parameters and display contents, and can be uniformly adjusted into an overall display picture according to the combination form; all the LED screens 3 and the walking drivers 21 and lifting drivers 22 of the corresponding movable frames 2 are controlled by a central control system, so as to realize synchronous and coordinated movement and lifting actions after debugging.

[0028] The walking track 1 has a supporting part 11. Both the front and rear edges of the supporting part 11 have guiding parts 12 extending upward. The supporting part 11 has a slot 10 that penetrates up and down and extends along the length direction of the walking track. The movable frame 2 has a plurality of extending parts 23 extending above the supporting part 11. A walking wheel 24 and a guiding wheel 25 are rotatably fixed on the extending part 23. The walking wheel 24 is supported on the supporting part 11, and the guiding wheel 25 is in contact with the side wall of the guiding part 12. Among them, a guiding wheel 25 is provided on each side of the walking wheel 24, and the axis of the walking wheel 24 is perpendicular to the axis of the guiding wheel 25.

[0029] As Figures 1 to 6 described, the walking track of each left LED screen assembly 110 corresponds to the walking track of a right LED screen assembly 120 and is symmetric about the center axis of the stage left and right. The moving trajectories of all the LED screens 3 share the same center. One of the adjacent two LED screens in the left LED screen assembly 110 is relatively located inside the circumferential direction of the other LED screen. One of the adjacent two LED screens in the right LED screen assembly 120 is relatively located inside the circumferential direction of the other LED screen. As Figure 1 shown, the left first LED screen 111 is located outside the circumferential direction (rear side) of the left second LED screen 112. The left second LED screen 112 is located outside the circumferential direction (rear side) of the left third LED screen 113. The right first LED screen 121 is located outside the circumferential direction (rear side) of the right second LED screen 122. The right second LED screen 122 is located outside the circumferential direction (rear side) of the right third LED screen 123.

[0030] As Figure 1 shown, when the left first LED screen 111 of the left LED screen assembly 110 and the right first LED screen 121 of the right LED screen assembly 120 approach each other to the limit position, the corresponding left first LED screen 111 and right first LED screen 121 are in contact. As Figure 2 shown, when the adjacent two LED screens of the left LED screen assembly 110 move away from each other, the end of one of the adjacent two LED screens of the left LED screen assembly 110 is located directly in front of the end of the other LED screen; when the adjacent two LED screens of the right LED screen assembly 120 move away from each other, the end of one of the adjacent two LED screens of the right LED screen assembly 120 is located directly in front of the end of the other LED screen, that is, one end of the left third LED screen 113 is located directly in front of one end of the left second LED screen 112, and the other end of the left second LED screen 112 is located directly in front of one end of the left first LED screen 111.

[0031] This embodiment can provide higher flexibility and creativity, so that the screen layout and shape can be changed according to the performance needs, and more different performance imaging effects can be demonstrated. Moreover, a simpler mechanical structure can be adopted to ensure stability during movement, and a lifting drive and a walking drive with lower costs can be used, which has the advantage of reducing the stage use cost.
