A certain number of LED lamp beads are lighted in some fixed position of pearl on Plane of rotation, at the same by the refreshing of certain frequency come
Realize that the variation of image will generate persistence of vision phenomenon, people when refreshing frequency reaches certain range in the vision of people
Eyes will see the action less than refreshing, but in the case where the residual vision imaging of upper width picture disappears not yet
The picture of a new width is seen again；To produce visual illusion, that is, form successional picture.But existing POV is flat
The display module of face rotating display device is substantially linear type setting, and PCB circuit board is to carry out the strip of integral cutting,
Due to the display module only with linear type, can be limited by LED drive chip so that its picture display frequency is relatively low, and reaches
Less than corresponding display fluency, in order to improve the refreshing frequency of display module, that is, reach corresponding display fluency, people make
It is assembled into display module with multiple small unit display modules, but multiple unit display modules are often produced when carrying out assembled
The raw mutually cause property that symmetrically differs, can make display device when rotated disequilibrium and vibrate；If multiple junior units shown
Show that the PCB circuit board of component carries out integral cutting molding, but the leftover pieces that PCB circuit board generates after dicing can be made more,
It is i.e. more serious to the waste of PCB circuit board base material, to improve the production cost of display module, while integral cutting
PCB circuit board then needs to replace entire display module when being damaged in use, so that POV planes
The maintenance cost of rotating display device is higher.

And interconnecting piece and PCB circuit board are integrally formed, the PCB circuit board is provided with one piece or more, and the interconnecting piece of PCB circuit board with
The center of circle of fixed seat is basic point, and is integrally attached in fixed seat in 360 degree successively, and the LED light emitting diodes are provided with one
More than a, and linearly it is sequentially arranged in PCB circuit board and interconnecting piece.
Preferably, the interconnecting piece is arranged in fan-shaped, and the angle of interconnecting piece radius is 90 degree, contribute to interconnecting piece it
Between complement each other to form entirety, avoid display module assembling after asymmetry and cause rotation when vibration.
Preferably, the LED light emitting diodes are three-primary color LED light emitting diode, and LED light emitting diodes and PCB
Circuit board is fixedly connected with interconnecting piece, the image for contributing to display colored.
The utility model has the technical effect that following aspect：Due to being shown provided with several split type units
Then a unit display module is assembled into complete display module by component again, therefore avoid the PCB circuits to display module
Plate generates more leftover pieces after carrying out integral cutting, to reduce the waste to PCB circuit board motherboard, that is, reduces aobvious
Show the production cost of component；Due to being provided with interconnecting piece, and interconnecting piece is arranged in 90 degree of sector, and interconnecting piece is with fixed seat
For the center of circle being basic point is integrally attached in 360 degree in fixed seat, therefore avoids display module in assembly because of asymmetry,
Display device is set to cause unbalance vibration at work；Since provided with split type display module, such as single display module exists
When being damaged during use, then the single display module of damage is only needed replacing, and avoids monoblock type display group
The integral replacing of part reduces corresponding maintenance cost.
