The difference among hologram fan / projection / cabinet
Holographic cabinet, 3D holographic fan, and holographic projection are one of the most widely used products in the exhibition and display industry, and we occasionally see them in our daily life. Although all holographic products can display naked-eye 3D effects without wearing polarized glasses, there are big differences in practical applications. Next, let us explain the technology and characteristics of this model to everyone.
The concept of three items
1. What is a holographic cabinet
The holographic cabinet is a 3D technology that uses holographic projection without wearing glasses, and the audience can see 3D virtual characters. This technology is widely used in some museums and stages, and it is more popular on the stage in Japan. Holographic 3D projection equipment is not realized by using digital technology, but projection equipment projects images from different angles onto a holographic film imported from abroad, allowing you to see other images that do not belong to your own angle, thus realizing the real holographic 3D image.
2. What is a hologram fan
Hologram led fan are also called 3d led fan, 3d fan, 3d hologram fan and holographic advertising machine. The principle of 3D fan screen imaging is commonly referred to as "POV" (visual persistence) display technology. The rotating display crystal constantly changes, utilizing the principle of visual persistence of the human eye to form a complete and continuous image, achieving a 3D holographic imaging effect.
The phenomenon of visual persistence means that when the human eye is observing the scenery, the light signal is transmitted to the brain nerve, which takes a short time. After the end of the role of light, the visual image does not disappear immediately. This residual vision is called "after image", and this phenomenon of vision is called "visual persistence".
Movies use this visual persistence to quickly transform static scenes into active images.
The 3D effect naked eye 3D fan screen utilizes this principle, which is a 3D effect that can be seen on the screen without wearing professional glasses,
It is small in size, low in power consumption, and has an extremely high turnover rate. One click transfer of mobile app, convenient and fast, creating the coolest visual effects.
3. What is holographic projection
Holographic projection technology (front-projected holographic display) is a kind of 3D technology, which originally refers to the technology of recording and reproducing the real 3D image of an object by using the principle of interference. Later, with the guidance of sci-fi movies and commercial promotion, the concept of holographic projection gradually extended to commercial activities such as stage performances and exhibitions. But the holography we usually know is often not a holographic projection in the strict sense, but a kind of holographic projection technology that uses methods such as Pepper's phantom and edge blanking to achieve 3D effects.
Application of three items
1. Price of hologram fan / projection / cabinet
One of the difference between the 3d holographic led fan, holographic projection and holographic cabinet is cost-effectiveness. In addition to the product price, the later maintenance and display screen of the product are also one of them. On the current market, the price of general holographic fan is around 500 USD, while the price of the holographic cabinet is nearly 2,000 USD, and the price of the holographic projection is nearly 5,000 USD. In terms of the fidelity of the display screen, hologram fan can achieve high-definition and ultra-clear picture quality, while the holographic cabinet and holographic projection are slightly behind. Compared with holographic cabinet and holographic projection, 3d led fan also have great advantages in later maintenance. When holographic fan don't work, only precise location maintenance is required to solve the problem. When the holographic cabinet and holographic projection don't work, they can only be replaced as a whole.
2. Application field
In the field of application, holographic cabinet tend to be used in shopping malls, exhibition halls, museums and other scenes for single display, while holographic projection is the most widely used in stage performances. The application scenarios of holographic fan are comprehensive. At present, the market of holographic fan is not limited to entertainment, shopping malls, and exhibition halls. It is also involved in offline advertising display and brand promotion. The application fields are not only extensive, but also in The display is also diverse, and the size of the display screen can be changed at any time, which cannot be achieved by holographic cabinet and holographic projection.
3. Commercial
In the most important commercial aspect, the difference between the hologram fan and the holographic projection of the holographic cabinet is also very obvious. Although the holographic cabinet is large in size, its display area is small, and the display area ratio is less than 50%. At the same time, due to its large size, it takes up a lot of space in the market and is not easy to place. For holographic projection, although the display area can be adjusted, due to the principle of holographic projection, it cannot be blocked during the projection process, so it also has limitations. As for the hologram fan, although the body is small, it has a large display area ratio. At the same time, it is not easy to attract attention when it is placed statically. Only after it is running, consumers will find out that it is extremely commercial.
No matter in terms of cost performance, application field, or commerciality, there are obvious differences between 3D hologram fan, holographic cabinet and holographic projection, which are closer to market demand and investment benefits. At present, the carrier of hologram fan has became the star on the market, and is developing in the direction of life and popularity. Industry insiders believe that with the development of science and technology, hologram fan technology has been rapidly improved. At present, it has shown a trend of gradually replacing flat screen display. In the future, people may no longer choose professional theaters and professional equipment to watch 3D movies. Hologram fan will enter life, and with the application of 5G, more intelligent human-computer interaction will be realized. In business and life, hologram fan will show strong adaptability and become a new generation of unicorns in the market.
