The display screen rotating layer by layer mainly comprises a base 1, a top seat 13, a column (a small section can be seen from the top in the figure), two electric drivers (respectively arranged in the base 1 and the top seat 13) and 24 rotating units 4. The outer surface of the rotating unit 4 is covered with display components provided with LEDs, and the display components are respectively stacked on the upright posts layer by layer and can rotate around the upright posts respectively. The shape (radial section) of the rotating unit 4 is oval, but can be made into other shapes, such as rectangle, triangle, polygon, and can present colorful visual effect when rotating.

Fig. 2 is a schematic diagram of a part of the internal structure of embodiment 1, please refer to fig. 2. The upright 2 is vertically mounted between the base 1 and the top seat 13, and the two electric drives 3 are respectively mounted in the base 1 and the top seat 13 and are respectively electrically connected to a rotation controller (mounted elsewhere, not shown in the figures). The rotary units 4 are divided into two groups, an upper group 15 and a lower group 16, each group showing 3 rotary units 4, respectively, wherein the middle rotary unit of the lower group 16 has the display module and the display module support removed. The rotary units 4 are respectively mounted on the uprights 2 one by one and are rotatable about the uprights 2. The two ends of the rotating units 4 are respectively provided with face gears 11, and in each group, the rotating units are respectively meshed and driven by adjacent face gears according to set gear gaps; there is no drive connection between the upper set 15 and the lower set 16. The electric drive 3 is connected via a face gear 11 to drive the face gear 11 of the closest rotary unit 4. In this case, the electric drive 3 comprises, as components, a stepping motor, a reduction gear and a drive gear set, which is connected to the drive face gear 11. Display units 5 (5 are shown in the figure) are respectively fixedly installed on the outer surface of the rotating unit to rotate around the column 2 with the rotating unit 4.
