Because of the reason of rotation, the number of lamp beads needs to be increased for increasing display pixels, if the number of lamp beads is increased, then, the wind resistance is increased, in order to ensure the display effect, and reduce the wind resistance again, we have adopted the mode of moving mechanism moving lamp bead plate 11 to realize, moving mechanism adopts high-frequency response electro-magnet 13, high-frequency response electro-magnet 13 symmetry is installed on upper beam 301 and lower beam 302 of lamp bead mount 3, telescopic link 14 and lamp bead plate 11 upper and lower end fixed connection of high-frequency response electro-magnet 13, all offer the guide slot that is used for lamp bead plate 11 to slide on left montant 303 and the right montant 304 of lamp bead mount 3.

If a cylinder is to be shown, then lamp pearl from the bottom up is whole to light, because rotatory relation, a very fast 3D cylinder has just shown, no matter from the preceding left and right sides direction looks, all is a cylinder to because under the effect of 3 rotations of lamp pearl mount and high bright lamp pearls, lamp pearl mount 3 can disappear from people's eyes, thereby only sees a 3D cylinder, and the display effect is better.
If a cube is to be displayed, the Hall sensor 7 is used in the working flow of the lamp beads to provide information of an original point and 180 degrees of rotation, and the opening and closing sequence of each row of the lamp beads can be calculated from the information of the original point and 180 degrees and the rotation time of each circle, so that the cube can be displayed by circulating the operation of each circle of the lamp beads. For example: the lamp pearl of the bottom row, when crossing original point and 180 degrees, as the diagonal of cube, the lamp pearl is just lighted all this moment, because every circle rotational speed is unanimous, if 360 parts are divided into equally to a round, just can calculate the quantity of the lamp pearl of lighting up at every moment, and the lamp pearl is with corresponding reduction and increase at different moments, forms a cube. As shown in fig. 3, when the zero-crossing point is reached, the corresponding lamp beads are lighted, when the lamp beads are operated to the second position, the number of the lamp bead displays is updated, and so on, and after one rotation, the operation is restarted.
The embodiment further provides a rotating L ED stereoscopic display method, which includes the following steps:

Step S13, after the central control board is powered on, the main control chip FPGA17 receives program information to be displayed through the WIFI module 18, and the main control chip FPGA17 stores RGB data in corresponding storage chips respectively.
Step S14, when the Hall sensor 7 detects that the lamp bead plate 11 is at 0 degree, the main control chip FPGA17 starts to refresh data in a new round, and the lamp beads are regularly lightened by the lamp bead driving chip 28.
Step S15, when the Hall sensor 7 detects that the lamp bead plate 11 rotates to 180 degrees, the moving mechanism at the upper end drives the lamp bead plate 11 to lift upwards for a certain distance, and the main control chip FPGA17 regularly lights the lamp beads through the lamp bead driving chip 28; 0 ~ 180 scan a screen data earlier, promote the screen 180 in, 180 ~ 360 scan another screen data again, after rotating 360 like this, just constituted the higher image of a pixel, guaranteed display effect to owing to reduced lamp pearl quantity, reduced the windage. For example: the first 180 degrees is equivalent to scanning the dot matrixes of the 1 st, 3 rd, 5 th and 7 th rows, the lamp bead plate 11 is lifted (the lifting distance is 5 mm) at 180 degrees, the second 180 degrees is equivalent to scanning the dot matrixes of the 2 nd, 4 th, 6 th and 8 th rows, and after the rotation of 360 degrees, the dot matrixes of the 1 st, 2 nd, 3 th, 4 th, 5 th, 6 th, 7 th and 8 th rows form a picture, so that the distance between the lamp beads is 10 x 5mm (10 is the row spacing, and 5 is the column spacing), and the same effect as 5 x 5mm can be displayed.
Step S16, after the lamp bead fixing frame 3 rotates 360 degrees, a complete three-dimensional image is formed, and the moving mechanism at the lower end drives the lamp bead plate 11 to return to the original position downward.
The moving mechanism mentioned in the method can use the high-frequency response electromagnet 13 in the embodiment, and can also use a push-pull mechanism such as an electric push rod, a hydraulic cylinder, an air cylinder and the like, but the movement is not as fast as the high-frequency response electromagnet 13.
In order to ensure the display effect and reduce the wind resistance, besides the mode of using the above moving mechanism to move the lamp bead plate 11, another method can be used to implement the method, namely: the moving mechanism is removed, the whole lamp bead plate 11 is divided into a left half screen and a right half screen from the middle, the left half screen is provided with lamp beads (line/column … 1, 3 and 5) in odd rows, the right half screen is provided with lamp beads (line/column … 2, 4 and 6) in even rows, and under the condition of improving the rotating speed of the motor 2, a better display effect can be realized, and the wind resistance is reduced. It should be emphasized that any method of displaying beads in odd and even rows/columns to form a whole image falls within the scope of the present invention.
The invention can be watched from different angles, can watch real three-dimensional effect, greatly enhances the visual appreciation, is wholly appreciated by people in a mode of an appreciation column, and is suitable for occasions such as squares, scenic spots, indoor halls and the like.
