The 3D holographic advertising machine is a display device composed of LED light strips that looks like a fan. Its imaging effect uses the principle of human eye persistence, so that viewers can see graphics, animation and video imaging effects.
When imaging, all the content we see is LED light, and other surrounding content is relatively dark, so when the 3D holographic advertising machine is working, the user will only receive the stay of the bright light subconsciously, and ignore the dark light. present, so as to see the three-dimensional effect suspended in the air.
What technology does the holographic projection advertising machine rely on?
The working principle of 3D holographic advertising machine mainly uses POV technology, that is, portrait persistence technology. The holographic fan realizes imaging through high-speed rotating LED light strips. After that, it will remain for a while. The time required to see the image from the human eye and then transmit the image to the brain through the optic nerve is twenty-fourths of a second; when the 3D holographic advertising machine is running fast, the frame rate is generally maintained at about thirty frames per second, which means that each picture The freeze-frame time is one-thirtieth of a second. When the transformation speed of multiple freeze-frame pictures exceeds the frame rate displayed by the human eye, a continuous picture can be formed, so that the imaging effect is realized.
The advantages and prospects of 3D holographic advertising machine。
1. High brightness, no fear of day and night
The 3D holographic advertising machine is densely arranged by hundreds of high-quality LED lamp beads. It is a luminous product itself, and it can be seen in the dark without the help of other lighting equipment. It is a very dazzling device. Its brightness can make the device still clearly visible during the day, so there is no problem for businesses to use the 3D holographic advertising machine during the day.
2. Various sizes and models, multiple screens can be connected
There are eleven models of 3D holographic advertising machines, and the size of a single unit ranges from 30cm-100cm. A variety of models support multi-screen display of equipment, and can form a 5-meter square giant screen.
3, a variety of operation methods, content supports various formats
The 3D holographic advertising machine supports TF card, mobile phone and computer control, and the content is easily replaced. The TF card only needs to convert the content into bin format and import it into the TF card, then insert it into the device, and then use the remote control to control it; download and install the corresponding software on the mobile phone, open the software and connect to the running device WiFi, and then the operation of the device can be controlled. Follow the instructions to upload the content on your phone. Content supported formats are MP4, AVI, RMVB, MKV, GIF, JPG, PNG.
The advantage is that the power consumption is low and the effect is cool. Of course, there are still some problems, such as insufficient clarity.
Application fields of holographic projection technology
It is suitable for expressing individual items with rich details or internal structure, such as famous watches, famous cars, jewelry, industrial products, characters, cartoons, etc., giving the audience a completely three-dimensional feeling.
This display method requires the use of a pyramid-shaped projection glass, and a screen is placed at the apex of the pyramid, which is reflected through the four planes of the pyramid, creating the illusion that the projection is suspended in the hollow part of the pyramid. Because the four planes project images of four angles of the object, and the object is generally kept rotated, although this display method is also 2D, the sense of reality is even stronger than true 3D.
