As shown in Figure 1 to Figure 3, a kind of 3D holography lenticular display that the utility model preferred embodiment provides, packet Include: rotary drive mechanism 100, the driving of rotary drive mechanism 100 have a fixed disk 200, are arranged in the fixed disk 200 There is an indication mechanism 300；The indication mechanism 300 includes: lower frame 301, with the lower frame 301 upper side frame disposed in parallel 302, two lamp bars 303 of 302 end of lower frame 301 and upper side frame are set；The outer surface of two lamp bars 303 is all arranged The RGB LED304, any RGB LED304 for having several columns linearly to arrange include that LED driving chip 314 and setting exist LED drives the LED unit array 324 on chip 314；The LED unit array 324 includes red LED element, green LED member Part 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, two lamp bars 303 form a 3D holography cylinder, are all it can be seen that 3D holography cylinder at 360 degree The 3D rendering of upper display.

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 two 303 lamp bars of lamp bar are by certain track movement, since each RGB LED will form a track Line, these trajectory lines just will form a track plane, revolve in cycle turnover in two lamp bars 303, each RGB LED it Can all have in trajectory line one it is corresponding at the time of it is corresponding, then track plane that lamp bar is formed and need picture one to be shown a pair of It answers, the lamp bar that movement is lighted according to needed for picture 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 utility model, as shown in Fig. 2, the length of two lamp bars 303 is all 517mm, the width of two lamp bars 303 are 10-15mm, and the length of the LED unit array 324 is 500mm, two neighboring The distance between LED unit is 1mm.

In the further preferred embodiment of the utility model, the RGB LED304 is provided with 10 column, each column RGB LED setting There are 500.

In the further preferred embodiment of the utility model, as shown in Figure 3 and Figure 4, main control is provided in the lamp bar 303 Plate 400, the master board 400 include that microprocessor 401, wireless communication module 402, data processing module 403 and SD card are read Modulus block 404.

When it is implemented, by the way that the picture of required broadcasting or video are sent master board by SD card or mobile terminal 400, the picture or video data are read in the master board 400, and are shown by RGB LED304, meanwhile, rotation is driven Motivation structure 100 drives indication mechanism 300 to rotate, so that indication mechanism 300 forms a cylindrical surface when rotated, on the cylindrical surface On the 3D picture that can show or photo, advertising results it is splendid.

When it is implemented, the indication mechanism 300 is particularly shown process are as follows: first by terminal (including mobile phone terminal and Web terminal etc.) with the master board 400 (wireless communication module 402) is communicated, the then downloading of master board 400 is uploaded from distal end Video, data processing module 403 is decoded these data after completion to be downloaded, and passing through data processing module 403 will The video of downloading be decoded into the lenticular display can with cognizance code (common video frame number than lenticular display know Other frame number wants low, public 1 second 16 frame of video, and our video then needs 24 frames), last master board 400 is receiving To after play instruction, these videos are played out.

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 decoding becomes 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 of ARM Cortex-A7 Processor can be with the various workloads of efficient process and background task, such as social media and email synchronization, audio or video Play and other be switched on always, networking tasks always, especially in video playing task with very big advantage.

In the further preferred embodiment of the utility model, the wireless communication module 402 is Wi-Fi module, Li-Fi mould Block, bluetooth module, NB-IOT communication module or 4G, 5G communication module.

Wi-Fi is a kind of technology for allowing electronic equipment to be connected to a wireless lan (wlan), usually using 2.4G UHF or 5G SHFISM radio frequency band.Being connected to WLAN is usually to have cryptoguard；But can also be it is open, this Sample allows for any equipment within the scope of WLAN can connect.

Li-Fi is a kind of completely new wireless data transmission technology, is the abbreviation of Light Fidelity, by German physics Family's Harald Haas (Herald Haas) is researched and developed.It carries out data by changing the flicker frequency of room illumination light Transmission, the data of transmission per second are more than 10Mb, equally matched with typical broadband connection.In other words user opens room electric light 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.

In the further preferred embodiment of the utility model, as shown in figure 5, the rotary drive mechanism 100 includes: driving electricity Machine 101, and for power supply to be converted into power control board 102 used in driving motor 101.

Assuming that the frequency of RGB LED304 is 30, then the revolution number in one minute of the driving motor 101 is 30* 60/2=900.Assuming that the time required for each image is 1 second/60=16.66 milliseconds in per second in 60 images.

In the further preferred embodiment of the utility model, the DC voltage of 12V is converted into 5V's by the power control board DC voltage.
