In fact, the so-called naked-eye 3D means that the eyes can see two pictures with parallax on the display screen without wearing 3D glasses, and the object images are reflected by the brain, so as to achieve a three-dimensional visual effect. The “3D” effect of Coca-Cola’s advertisement is not through technical processing of the playback device, but through the depth-of-field picture with a strong sense of depth and the parallax principle of the human eye, an advertising method that creates a 3D visual illusion.

In the era of eyeball economy, traditional forms of outdoor display have been unable to attract people’s attention. To this end, outdoor 3D advertising came into being. It provides an unimaginable and creative way to bring people a new visual impact. It can be said that 3D outdoor advertising is the most intuitive on-site advertising in the world. It relies on realistic effects and gorgeous visual experience to attract consumers, thereby enhancing brand publicity. It has been used by more and more businesses and has become a new model of outdoor advertising investment.

First of all, 3D outdoor advertising enhances the effect of advertising communication and attracts people’s attention. 3D advertising itself is a visual game, people’s eyes are easily deceived by the illusion it creates, thinking that the scene on the screen is real, making people feel like they are there. Therefore, people are easily attracted to it and stay for a long time, which increases the enthusiasm of people to participate. Secondly, advertising companies and media owners will pay special attention to and apply new media technologies such as 3D technology in order to improve their own level. In addition, the emergence and development of 3D outdoor advertising is the inevitable result of the development of outdoor advertising technology. The emergence and wide application of each new technology will inevitably lead to production changes in related industries and even the entire society, and the outdoor advertising industry is no exception. Nowadays, in terms of outdoor advertising technology, naked-eye 3D technology is constantly maturing and improving, which will inevitably bring outdoor advertising to a higher level on the original basis.

In recent years, LED display screens, as the mainstream outdoor billboards in the market, are almost all over the city’s streets and alleys, becoming the largest media carrier for advertising, but playing 3D advertisements has strict requirements on the effect of LED display screens. As the leader of domestic LED displays, Hua Fucheng has built many high-quality outdoor LED advertising screens. These high-quality LED displays with perfect display and stable effects are fully capable of presenting “3D” effects, which is more conducive to the promotion of advertising brands. spread. Just imagine that the 3D effect advertisement is perfectly presented on the outdoor LED display, and its vivid and lifelike pictures will also play a greater role in decorating the city and become a beautiful landscape!

With the continuous improvement of packaging technology, the dot pitch of full-color LED displays is getting smaller and smaller, the resolution is getting higher and higher, and the color, contrast, viewing angle, etc. are getting better and better, and people are becoming more and more dissatisfied. Since only the display screen is used to display the 2D material, higher requirements are put forward. Therefore, the 3D full-color LED display came into being, and with the ultra-clear small-pitch LED display, it achieved an excellent visual experience. In recent years, various large-color LED display manufacturers have made great efforts to launch various 3D solutions in the field of 3D display.

It is expected that in the near future, LED movie screens will be replaced in cinemas, taking advantage of the high brightness of LEDs and 18-bit grayscale. Compared with traditional projection projection, the 3D solution has outstanding advantages and a full three-dimensional effect. At present, it has been put into use in some countries and regions, such as the Kwai Tsing Theatre in Hong Kong and the Milan World Expo.

At present, 3D cinemas mostly use 3D, a type of polarized 3D, which is based on the visual difference from light. At present, many companies are developing and producing naked-eye 3D full-color LED displays. Many problems will be reflected in this process. The most critical technical point is the “multi-view” design, so that the audience can see the 3D effect no matter where they stand. Now whether it is one, two, four, or eight viewpoints are easy to do, but it will be more difficult to do dozens of viewpoints.

In order to make up for some technical limitations of naked-eye 3D technology, some full-color LED display manufacturers have gradually turned to active 3D technology in the process of research and development from time to time. Active 3D technology can also be called shutter-type 3D technology. It is realized by greatly improving the refresh rate of the picture. It divides the image into two groups according to the frame to form the corresponding picture on the left and right, and continues to interlace the generated images. The synchronized on/off operation of the lenses of the shutter glasses sees a 3D image. Different from polarized 3D, it can restore the original resolution of the picture, and you can easily enjoy full HD 3D images, breaking through the limitations of the original naked-eye D multi-view position.

The application of 3D display technology in full-color LED display has greatly changed people’s visual experience, and it has also had a huge impact on the full-color LED display market. As a full-color LED display manufacturer, the technological innovation from 2D display to 3D display Under the situation, it will also face new challenges and impacts.

The application of 3D technology will effectively avoid industry homogeneous competition. The application of 3D technology to full-color LED displays is a brand new field that only a few companies in the mainland are developing. It can be said that the application of 3D technology on the full-color LED display will add additional value to the full-color LED display products. Win the market initiative in the competition. In addition, because the application of 3D technology in LED is a new thing, there is no problem that the market will be dominated by some large production areas or large enterprises in the mainland, and this new field will take the lead.

Secondly, full-color LED display manufacturers need to seek diversified expansion. Affected by 3D display technology, the first to bear the brunt is the conservative 2D display technology screen suppliers. As the market such as participating in the exhibition is more inclined to the needs of content differentiation and personalized image, and more or less turn to 3D technology. , which is bound to affect the aggressive business of traditional 2D suppliers. Therefore, in the face of such a positive and powerful attack, most screen suppliers need to change the strategic direction of their product lines, face challenges in a diversified and differentiated form, and cooperate with 3D full-color LED display manufacturers and institutions to expand Product line, adhere to the vitality of competition, and keep pace with the times

As a leading LED display provider in the country, LED scree provides users with the most suitable 3D display solutions for LED displays with its consistently leading innovation and development capabilities.

The 3D display control solution we use can solve various problems that users are likely to encounter in actual use, and provide display users with flexible and convenient system solutions, simple and intuitive operating software, high-quality film sources, and interference-free 3D glasses. . While adding highlights to the display, it relieves everyone’s worries.

At present, the mainstream 3D display has occupied most of the country, and the known 3D display devices include stereo vision, helmet-mounted display, CAVE, naked-eye stereo display and true 3D display. The main 3D stereoscopic display technologies are as follows.

Glasses 3D Display Technology

Glasses-based 3D technology can be subdivided into three main types: chromatic aberration, polarized light, and active shutter, which are commonly referred to as color separation, light separation, and time division.

Anaglyphic 3D technology (Anaglyphic3D): It is used with passive red-blue (or red-green, red-cyan) filter 3D glasses. This technology has the longest history, the imaging principle is simple, and the implementation cost is quite low. The cost of glasses is only a few dollars, but the 3D picture effect is also the worst.

Polarization 3D Technology (Polarization 3D)
It’s also known as polarized 3D technology, and it works with passive polarized glasses. Polarized 3D uses the principle that light has a “vibration direction” to decompose the original image. First, the image is divided into two groups of vertically polarized light and horizontal polarized light, and then the left and right 3D glasses use polarized lenses with different polarization directions. , so that the left and right eyes of the person can receive two sets of pictures, and then the brain can synthesize the three-dimensional image.

Shutter 3D Technology

This 3D technology is most widely used in TVs and projectors, with relatively more resources and excellent image effects. It is respected and adopted by many manufacturers, but its matching 3D glasses are expensive. At present, 3D TVs launched by LG, Samsung, Panasonic, Skyworth and other brands all use active shutter 3D technology.

3D Display Technology Development Trend

Display technology has gone through a process from black and white display to color display, and from ordinary color display to high-definition color display. At present, flat display technology has made great achievements. But because the objective world is a three-dimensional world, any object has the three-dimensionality of x, y and z. In order to pursue the maximum true reproduction, one of the main ways is to achieve three-dimensional sense.

At present, the mainstream 3D display has occupied most of the country, and the known 3D display devices include stereoscopic vision, helmet-mounted display, CAVE, naked-eye stereoscopic display and true 3D display.

In 3D stereoscopic display technology, it will gradually develop from active glasses and polarized glasses to naked eye 3D and true 3D stereoscopic display technology.

It should be mentioned that many people do not know the difference between naked-eye 3D LED display and holographic projection. They feel that they are very similar, but in fact, there are still many differences between the two.

The difference between naked eye 3D led display and holographic projection

3D special effects are display effects that have become popular in recent years. Since the movie “Avatar”, 3D display has entered people’s field of vision. Up to now, 3D technology has been used in many fields, and the LED display industry can also achieve 3D effects. In fact, there are many 3D technologies, holographic projection and naked eye 3D are one of them, so what is the difference between these two technologies?

Glasses-free 3D technology is currently in the development stage, and its development is divided into two major directions, one is the development of hardware equipment, and the other is the processing mechanism for displaying content. In fact, naked-eye 3D led displays have been launched from time to time in recent years, but in general, due to technical limitations, manufacturers that can independently develop naked-eye 3D led displays are one in a hundred.

Because of the difficulties, the naked-eye 3D LED display in the true sense cannot be applied on a large scale at present. There are some manufacturers in the industry that have realized the industrialization of naked-eye 3D LEDs through acquisition or cooperation. At present, all naked-eye 3D led displays are realized indoors, and most manufacturers do not have the ability to develop outdoor naked-eye 3D led displays.

This also restricts the implementation of naked-eye 3D led displays.
Nevertheless, LED display manufacturers have never given up on the development of naked-eye 3D, storage technology, and talent training are the most important things for enterprises at present. If you want to be invincible in the future 3D competition, you must plan ahead.

Different from the naked-eye 3D LED display display method is holographic projection, which is a technology that presents videos or images in the air. Simply put, it is a three-dimensional image technology that uses optical principles such as interference and diffraction to record and reproduce the image of an object.

The holographic projection methods commonly used in the market can be roughly divided into two categories: one is the rear projection method, the projector directly projects the content to be projected onto the holographic film; the other is the use of reflection, which reflects the projection or LED image onto the holographic film On the holographic film placed at 45 degrees, the effect will be more realistic, but the cost and cost will be higher. For example, this method is often used in large-scale parties.

In fact, it is a special projection screen. This kind of projection screen uses a transparent film base, and a sandwich is sandwiched between the production of the film base. The result of this is that those who watch from a distance can only see floating in the air. content, and the transparent film base is basically invisible. This creates a visual hallucination, feeling that the content is very peculiarly separated from the display medium and exists in the air.

Another common holographic statement is the holographic projection of space. This display method is more advanced and more realistic, as if it were on the scene. This is probably the expression method that thousands of people dream of, and many people claim that they are saw the future.
Regardless of the above methods, it is closely related to the LED display. After understanding some technologies related to 3D LED display, many customers may still want to know how much the naked eye 3D LED display generally costs.

How much is the naked eye 3D LED display?

The price of naked-eye 3D LED display includes two aspects, one is the screen body and the other is the material. The price of the screen depends on the model, and the material depends on the display content.

The price of the led display screen is directly linked to the model. The smaller the model, the higher the price (under the same configuration). In addition to the model, the price of the entire screen from ordering to display also includes the following: screen, control system, installation and debugging, logistics and transportation, structure…

The materials are made by professional companies or teams, customized according to customer needs, and the cost is not low. Although the screen is used as a carrier, the naked-eye 3Dled display has no matching materials, and no matter how good the screen is, it cannot show the corresponding effect.

LED scree is a manufacturer of LED display screens, but in addition to providing screens, it also has a professional production team for naked-eye 3D materials, naked-eye 3D led displays, and one-stop all-inclusive screen materials.

Regarding the cost of the naked eye 3dled display screen, the naked eye 3dled display screen used in outdoor advertising is more than a few hundred square meters, and the entire project is in the tens of millions. Shenzhen’s first vertical 3D giant screen built by Dayuan Intelligent, the model selected is P6, the entire screen area is 670 square meters, and the cost is also more than 10 million. Regarding the price of naked-eye 3Dled display, take the class as a reference.

The naked-eye 3D large screen “Light of Asia” on Guanyinqiao Pedestrian Street in Chongqing

It is reported that the naked-eye 3D large screen “Light of Asia” on Chongqing Guanyinqiao Pedestrian Street was built by Leyard, a well-known company in the industry. The project takes into account the design concept of “architectural aesthetics and business circle environment”. While looking forward to the prosperity of the city, it also places people’s vision in the best viewing area, so as to bring people an immersive visual experience.

There are many classic cases similar to the “Chongqing Guanyin Bridge Pedestrian Street Spaceship”, such as the earlier “Chengdu Taikoo Li Spaceship”, “Guangzhou Beijing Road Naked Eye 3D Curved Screen” and “Shanghai Aosuo Future City”. Once this type of display project is displayed, it can often achieve unexpected results and cause great sensation. The flexibility and charm of LED display can be fully displayed outdoors or in other specific places, which has the incomparable advantages of other displays.

However, once upon a time, we were still worried about the development prospects of outdoor LED displays. Since outdoor advertising is being cleaned up everywhere, it also affects the development of outdoor displays, and many outdoor displays have become the object of cleaning. The audience has long been surprised by the outdoor LED display, lacking freshness, and even complaints caused by light pollution and quality accidents have occurred frequently. For a period of time, the outdoor LED display has a very poor reputation.

The concentrated appearance of display projects like “Light of Asia” this time has brought pedestrians’ attention to the LED display again, which has indeed turned a corner for the outdoor LED display industry. Why can outdoor LED displays attract people’s attention again? The reason is that this type of screen incorporates a new design concept, combined with naked-eye 3D display technology, giving people a supernatural and extreme viewing experience Sexual visual sensory experience. The great success of these cases also shows that the visual sensory experience is the necessary factor to determine the “Light of Asia” to stand out.

“Chengdu Taikoo Li Spaceship” naked-eye 3D display

In recent years, thanks to the development of 5G, AR/VR and other technologies, people’s requirements for display have been continuously improved, and they are no longer limited to traditional flat-panel display, but a three-dimensional, high-definition, interactive visual sensory experience. The “Light of Asia” project created by Leyard is a classic case. According to reports, the “Light of Asia” project is an outdoor display project completed by Leyard in 2019.

However, after delivery and operation, it was only used to play some print advertising content, not from the perspective of visual sensory experience, which made the “Light of Asia” display project in a state of obscurity one year after the completion of the project.

There are countless LED displays that are as cool and hot as the “Light of Asia”. Although these displays have originality in shape or appearance, they are often “absent from the crowd” due to their monotonous content and lack of visual sensory experience. . It has to be said that this is also the most realistic portrayal of outdoor LED displays in the past.

Since the emergence of the wave tank “wave” in Seoul, South Korea, this “rule” has been broken. It is understood that the wave tank “wave” simulates the amazing effect of the waves rolling in the building, and through the form of sound effects, light and shadow blending, it gives people an immersive feeling. The wave tank “wave” received widespread attention and praise as soon as it was launched.

It is also because of the first test of the “wave” of the ocean water tank that LED display companies in the industry have launched their own LED displays with the ultimate visual sensory experience. These include “Chengdu Taikoo Li Spaceship” and “Guangzhou Beijing Road Naked Eye 3D Curved Screen” in the text.

However, this 3D display technology is actually applied in China earlier than in foreign countries. In 2016, Shanghai Sansi created a 3D effect screen in Beijing Juntai Department Store. Since then, due to the lack of visual materials, quite a number of LED displays with 3D display effects have been “bright pearl dark projection” and are willing to be ordinary.

Glasses-free 3D curved screen in Beijing Road, Guangzhou

From the wave water tank “wave” in Seoul, South Korea to the various types of naked-eye 3D displays that have appeared recently in China, it can be seen that the visual sensory experience is gradually becoming a “hard indicator” in the development process of LED displays, which is accepted and adopted by enterprises. . As one of the main application scenarios of LED display, stage rental is also inseparable from the performance of visual sensory experience. For example, this year’s “Shendu Month, Chinese Love” 2020 Gengzi Year CCTV Mid-Autumn Festival Gala LED display pays special attention to people’s visual sensory experience. The waterscape, rhythm, ancient buildings, full moon and other scenes are outlined vividly and vividly, giving people an immersive experience. It is foreseeable that the visual sensory experience will cover the entire LED display industry in the future.

Visual sensory experience is a “generic word” with rich meanings. To achieve this effect, technology and creativity are essential factors. “Chengdu Taikoo Li Spaceship” was jointly created by Lianjian Optoelectronics and FLINT WALK, a visual art conception company. Lianjian Optoelectronics used 90° seamless corner module technology, outdoor high-brightness wide-angle display panel technology, Advanced technologies such as high-contrast light-absorbing masks instantly inject “new life” into the overall wall.

The Flint Company is responsible for visual arts, using the focus of young people today. Entering the space station through the depths of the universe and then exiting the screen means a new beginning and debut.

It is also the perfect cooperation between Lianjian Optoelectronics and Flint Group that made the stunning appearance of “Chengdu Taikoo Li Spaceship”. It is understood that on October 2 alone, “Chengdu Taikoo Li Spaceship” was listed on Weibo’s national real-time hot search list TOP5, with 320 million views and 56,000 discussions. In addition, on the Douyin platform, “Chengdu Taikoo Li Spaceship” is also very popular, with 200,000 likes for a single video and tens of millions of views.

Through this, we can know that the LED display screen is in a stage of “transformation”, and the traditional large outdoor display screen is gradually becoming a “landscape point” in the city, thereby increasing the vitality of the city. At the same time, it can also be known that people’s pursuit of vision must be “new, strange, clever and interesting”, rather than a single boring flat display.

Therefore, when we carry out the scene application of the LED display, we must not only realize the integration of technology and creativity, but also pay attention to the development of the scene. Only in this way can we give the LED display an extremely rich visual sensory experience.

The centralized swiping of several Internet celebrity outdoor display projects not only makes the outdoor display take a long breath, but also makes LED display companies who are blindly working on the display hardware understand the truth that a good horse is matched with a good saddle. If you can’t achieve a combination of soft and hard, no matter how good the technical strength is, you can’t show it to your heart’s content.

The naked eye 3D craze, which is based on the Korean wave screen, shows that sometimes creativity and content are more important. there is nothing you can not do, only something you can not think of. After the Korean waves pierced this layer of window paper, we should think about where our gap is when we are in a state of enlightenment? With the widespread application of 5G and 8K technologies, the future of LED display is even more immeasurable. Jump out of the well and look up at the sky.
