In being arranged with multiple LED in same plane and on blade, the vane nose track of adjacent display cell is overlapping.
In the present embodiment, the equidirectional rotation of all display units, that is, be all clockwise, or is all counterclockwise；And rotate
Initial position is all vane tip interface point；Rotary speed is identical, lap, and timesharing enters, the same space, but it is different when
Between, and condition as defined in each vane tip size satisfaction.
As shown in figure 9, similarly O2" movement locus " X=31/2R0sin(-ωt)；Y=31/2R0cos(-ωt)；
The relative movement orbit of P points：
X=31/2R0sin(-ωt)-31/2R0/2；
Y=31/2R0cos(-ωt)+R0/2；
To obtain the final product after elimination ω t：
(X+31/2R0/2)2+(Y-R0/2)2=3R0 2
Blade shape in the present embodiment by the maximum boundary of blade as shown in fig. 7, be arranged to curve (X+31/2R0/2)2+
(Y-R0/2)2=3R0 2In one section, wherein R0For length of blade.When setting three blades in each display unit, when display is single
During first equidirectional rotation, it is ensured that adjacent display cell will not interfere between overlapping region, blade.In the present embodiment
Adjacent three display unit periods of motion schematic diagram is as shown in figure 8, also ensure that adjacent display cell between lap, blade
It will not interfere.But in the manufacturing process of actual blade, width of blade is necessarily narrower than two kinds of situations in embodiment 1,2,
So as to avoid producing interference phenomenon when rotated.
