Embodiment
Do further detailed explanation below in conjunction with accompanying drawing and embodiment specific embodiments of the invention, but should not limit protection scope of the present invention with this.
Among Fig. 1-8,1-wireless network module, 2-transceiver module, 3-control and broadcast module, 4-data storage and buffer module, 5-LED display module, 6-motor, 7-machinery mount, 8-rotating shaft, 9-high precision frequency converter, 10-case, 11-slip ring.
Shown in Figure 1 is that each ingredient of swept-volume three-dimensional display apparatus of the present invention connects synoptic diagram, comprising wireless network module 1, transceiver module 2, control and broadcast module 3, data storing and buffer module 4, LED display module 5, motor 6.
Like Fig. 2, Fig. 3, shown in Figure 4, the length of whole LED display module is 480 millimeters, and wide is 640 millimeters, is made up of 8 LED screens, and each LED screen is made up of with the LED panel data storing and buffer module 4, links together through contact pin between the two.LED screen installation process is following:
Step 1 a: blocks of data is stored and buffer module 4 and a LED panel utilize contact pin to link together, form a sub-LED screen.
Step 2: form other 7 sub-LED screens according to method in the step 1;
