As shown in Figure 1 to Figure 3, a kind of 3D holography conical surface display device that present pre-ferred embodiments provide comprising:
Rotary drive mechanism 100, the driving of rotary drive mechanism 100 have a fixed disk 200, are provided with one in the fixed disk 200
Indication mechanism 300；The indication mechanism 300 includes: support plate 301, is separately positioned on a left side for 301 left and right ends of support plate
Lamp bar 302, right lamp bar 303, the left lamp bar 302 intersect at top with right lamp bar 303；The support plate 301, left lamp bar 302
An isosceles triangle is constituted with right lamp bar 303, the angle between the support plate 301 and left lamp bar 302, right lamp bar 303 is all
It is 30 ° to 60 °；The support plate 301, left lamp bar 302, being all connected through a screw thread in right lamp bar 303 between the two；The left side
The outer surface of lamp bar 302 and right lamp bar 303 is disposed with the RGB LED304 that several columns linearly arrange from the top to the bottom,
The columns of the RGB LED304 successively increases from the top to the bottom；Any RGB LED304 includes LED driving chip 314
And the LED unit array 324 on LED driving chip 314 is set；The LED unit array 324 includes red LED element, green
Color LED element and blue-led element.
When it is implemented, the rotary drive mechanism 100 drives fixed disk 200 to rotate, i.e., indication mechanism 300 is around rotation
When driving mechanism 100 rotates, the left lamp bar 302 and right lamp bar 303 can be rotated around the center of fixed disk 200, the left lamp
Under the circumference of the high-speed rotation, left lamp bar 302 and right lamp bar 303 form a rotary cone for item 302 and right lamp bar 303, due to
The effect of RGB LED304, left lamp bar 302 and right lamp bar 303 form a 3D holography conical surface, are all it can be seen that 3D at 360 degree
The 3D rendering shown on the holographic conical surface.
Line, the principle of line forming face in rotation, by several RGB LED according to certain are formed in rotation according to multiple points
Aligned transfer.After the left lamp bar 302 and right lamp bar 303 are moved by certain track, since each RGB LED will form
As soon as trajectory line, these trajectory lines will form a track plane.It is revolved in cycle turnover in left lamp bar 302 and right lamp bar 303, often
One RGB LED can all have in its trajectory line one it is corresponding at the time of it is corresponding, then 303 shape of left lamp bar 302 and right lamp bar
At track plane and need picture to be shown to correspond, the left lamp bar 302 and right lamp bar 303 of movement are lighted according to needed for picture
It is formed by pixel corresponding to track plane, so that it may a picture is formed, to reach the display effect of 3D a kind of.
In the further preferred embodiment of the present invention, as shown in Fig. 2, the length of the left lamp bar 302 and right lamp bar 303 is all
The width of 500-600mm, the left lamp bar and right lamp bar is all 10-15mm, and the length of the LED unit array is 480-
500mm, the distance between two adjacent LEDs unit are 1-2mm.
In the further preferred embodiment of the present invention, the outer surface bottom of the left lamp bar 302 and right lamp bar 303 is set
RGB LED304 quantity has 10 column.
Since left lamp bar 302 and right lamp bar 303 are during rotation, closer to rotary shaft, its speed is bigger, therefore,
In the case where the LED unit of identical quantity, the brightness that the big position of speed is shown is higher than the small brightness of speed, thus makes
It is higher than bottom at the top brightness of conical surface display device, in order to solve the problems, such as brightness irregularities, in left lamp bar 302 and right lamp
When RGB LED304 is arranged in the outer surface of item 303, the columns that the RGB LED304 at top is arranged in, which is greater than, is arranged in middle part
RGB LED304, the columns that the RGB LED304 at middle part is arranged in are greater than RGB LED304 arranged at the bottom.Thus have
Effect solves the problems, such as that display brightness is non-uniform, so that the display brightness of entire conical surface display device is more uniform.
In the further preferred embodiment of the present invention, as shown in Figure 3 and Figure 4, master board is provided in the fixed disk
400, the master board 400 includes that microprocessor 401, wireless communication module 402, data processing module 403 and SD card are read
Module 404.
When it is implemented, by will be required by the mobile terminals such as SD card or mobile phone (certainly also including web page end)
The picture or video of broadcasting send master board 400, and the picture or video data are read in the master board 400, and pass through RGB
LED304 shows, meanwhile, rotary drive mechanism 100 drives indication mechanism 300 to rotate, so that indication mechanism 300 is rotating
When form a circular conical surface, the 3D picture or photo that can be shown on the circular conical surface, advertising results are splendid.
When it is implemented, the indication mechanism 300 is particularly shown process are as follows: first by the terminal (movement such as including mobile phone
Terminal and web terminal etc.) it is communicated with the wireless communication module 402 in the master board 400, then under master board 400
The picture or video uploaded from distal end is carried, data processing module 403 is decoded these data after completion to be downloaded, passes through
The picture of downloading or video data are decoded into the column conical surface display device by data processing module 403 can be with cognizance code
(common video frame number is lower than the frame number that conical surface display device identifies, public 1 second 16 frame of video, and our video is then
Need 24 frames), last master board 400 plays out these videos after receiving play instruction.
In video display process, play mode can be set first, obtained what acquisition once received every five minutes
Listed files (prevents file from updating not in time), then starts a timer and is used for program downloading list, then by downloading
Program data is decoded into the data that indication mechanism 300 can identify, reads and play these data after success to be decoded.
When it is implemented, the master board 400 is embedded with fpga chip, when the revolving speed for determining rotary drive mechanism 100
Afterwards, the time needed for calculating 1 equal part of the every rotation of lamp bar according to the isodisperse of image or video；Lamp bar is in rotary course in correspondence
Position of halving read corresponding equal partial images or video, and LED light bar is driven to be scanned, realizes the display of image.
Certain master board 400 is also embedded with tetra- core processor of ARM Cortex-A7.Tetra- core processor of ARM Cortex-A7 can

While, also access internet.
The basic principle of Li-Fi is the light and shade using light come encoded information.Light source is sent out using the high brightness of new era a kind of
Optical diode (LED) means that 1 when LED is bright, when LED has gone out means that 0.By increasing in the LED bulb in office why not to attract attention
Add a microchip, can control its millions of flashing per second, since frequency is too fast, human eye is never perceived, still
Photosensitive sensor can receive these variations.Like this, binary data are just encoded very quickly into light signal and go forward side by side
Effective transmission is gone.
NB-IOT is cried based on cellular narrowband Internet of Things, is implemented in cellular network, only consumes the bandwidth of about 180KHz,
It can be deployed directly into GSM network, UMTS network or LTE network, to reduce lower deployment cost, realize smooth upgrade.NB-IOT is IOT
The emerging technology in one, field supports low power consuming devices to connect in the cellular data of wide area network, also referred to as low-power consumption wide area network
(LPWA), meanwhile, NB-IOT supports stand-by time length, the efficient connection to network connectivity requirements higher device.
4G network refers to forth generation wireless cell phone communications protocol, is to integrate 3G and WLAN and can transmit high-quality
Measure video image.The main target of 5G network is that terminal user is allowed to be in connected state, the equipment that 5G network is supported in the future always
Running far deeper than is smart phone, it can also support smartwatch, body building wrist strap, intelligent home equipment etc..It is communicated using 4G, 5G
Module makes the communication speed of the lenticular display and client more.
