Three major display technologies create a three-dimensional immersive "view"

The world is three-dimensional, and people are three-dimensional. We also need a three-dimensional vision. In today's smart era, we are tired of flat scenes. How can we make our flat visual horizon more dimensional? Realize the fantasy vision we have seen in mythological stories or science fiction movies. It is no longer difficult for technology in the smart era. There are holographic projection technologies based on projection and holographic technology, VR devices presented through wearable devices, and even 3D scenes that can be realized with only a simple display device. Naked-eye 3D technology, what are the differences and developments among these three?

Wearable VR devices are not new to most people. The only thing we are familiar with is VR glasses. With the development of technology, most of today’s VR glasses can already be displayed online, without the need to set up the device as in the past. Insert relevant playback equipment and realize 3D resource viewing by loading a specific APP. All you need to do is search for relevant resources online and watch them. However, the current 3D resources are very limited, coupled with the visual fatigue caused by long-term use of wearable devices, which has also led to the embarrassing situation of "hot but not explosive" in the VR industry today.

Holographic projection. The holographic projection technologies that have been realized today are mainly divided into three types. One is air projection and interactive technology: A 29-year-old polytechnic graduate student named Chad Dyne in Massachusetts invented an air projection and interactive technology. This is a display technology. A milestone in technology, it can project interactive images on walls formed by airflow. This technology is derived from the principle of mirage, which projects images onto small water droplets formed by liquefaction of water vapor. Due to the uneven vibration of molecules, an image with strong layers and three-dimensionality can be formed. The second is a laser beam that projects a 3D image of an entity: This technology uses nitrogen and oxygen to disperse in the air, and the mixed gas turns into a hot slurry and forms a short-lived 3D image in the air. This method is mainly achieved by continuously carrying out small explosions in the air. The third is a 360-degree holographic display: This technology projects images on a high-speed rotating mirror to achieve a three-dimensional image.

Today's holographic projection technology is mainly used on the stage. It can not only produce three-dimensional aerial illusions, but also allow the illusions to interact with the performers to complete the performance together, producing shocking performance effects.

Naked-eye 3D technology. Compared with holographic projection and wearable VR devices, naked-eye 3D technology is not understood by most people. In the industry, the prospects for the future application of naked-eye 3D technology are also mixed. As for its display effect, it is recognized by most people. The 3D effect that can be achieved without the use of any other equipment other than display equipment has also attracted many companies' silent attention.

However, its shortcomings are also obvious. First, there is a lack of 3D resources. Similar to the embarrassing situation of VR, the lack of 3D film sources has caused related hardware to become a "baking meal without rice". No matter how clever you are, there is nothing you can do. Although some manufacturers have developed 2D to 3D technology, the results are not satisfactory. However, the number of 3D film source manufacturers is gradually increasing, which may be an opportunity for development for the industry. Second, cost. Whether for businesses or consumers, price is always a factor that needs to be considered. The scarcity of technology and the lack of film sources will undoubtedly lead to an increase in the cost of related resources, making it difficult for ordinary consumers to consume. In the future, its cost may decrease, but its early "loss-making investment" is still a big test for manufacturers.

For cost control, the main way manufacturers currently use 2D to 3D technology is to meet the needs of general consumers; to use pure 3D technology to meet the needs of high-end consumers. Third, environment. Because 3D space is not a plane project according to environmental classification, but a space construction. As a result, its application scenarios are mainly used in indoor spaces such as teaching, medical care, theaters, and stages, as well as home scenarios that have potential but still struggle to see much market demand. Due to the high cost, the main way to construct three-dimensional scenes today is holographic projection. This will become the main factor hindering the development of naked-eye 3D.

In the author's opinion, naked-eye 3D scenes are likely to be entered into educational scenes. After the main cost factor is overcome, part of the holographic projection market may be captured, forming two pillar technologies for indoor three-dimensional scene construction. For wearable VR devices, through its unique way of linking to the virtual world, it has achieved good results in the gaming industry, film industry, VR shopping and other fields. This is also the core advantage of VR equipment that is unique from the other two types of three-dimensional scene construction technologies. Outdoors, naked-eye 3D technology may be the only one that can be practical. However, in outdoor areas with complex people and traffic, it is still uncertain whether the realization of 3D effects is necessary.

Some people say that the emergence of naked-eye 3D comes at the wrong time. In fact, this is not the case. After all, very few companies can become industry pioneers, and most prefer to become entrepreneurs after the industry has become brilliant. As for the three major three-dimensional display technologies of holographic projection, naked-eye 3D, and VR, naked-eye 3D is a "dark horse" that people cannot see through. It has the blessing and development of international high-end companies like Kangdexin. Everyone, maybe you Be careful!
