At present, there are two main sources of LED display video content in the market. One is the project contractor, and the LED display manufacturer contracts to produce video content. One is a professional video content production team to output video content required by customers.
Take the naked eye 3dled large screen, which is hot again at present, for example. Let’s talk about the technical supply required for naked eye 3D effect presentation first.
The first is the hardware. The picture content played by the naked eye 3dled display has a strong visual impact. To achieve such an impressive effect, the display should pay more attention to high refresh, high gray scale, high dynamic contrast and smooth transition of surface / corner. In addition, in order to realize the normal playback of the picture on the large screen, it also needs the support of a hardware facility, that is, the playback server. The playback server needs to be connected to a professional graphics workstation and equipped with multi graphics card frame synchronization card to complete the perfect transfer of the picture from the computer to the large screen.
After that, let’s talk about the software requirements. In order to realize the naked eye 3D effect on the large screen with radian, a more professional decoder is required, and the decoder must be able to support the material mapping and correction function of the special-shaped display carrier, and support the low-level optimization of high bitstream decoding.

With the continuous development of technology, at present, the hardware and software of LED display technology can realize the playback of 3D video source, but the playback material can not be supplied freely.

The first is the single broadcast material. Some content materials only highlight the shock of 3D effect in the selection, or meet the advertising needs of customers. The successful cases of The led display company Optoelectronics in the field of naked eye 3D have attracted the attention of the industry in recent years. The 3D spaceship led giant screen located in taiguli, Chengdu. The picture of the video source is taken from the famous science fiction film star trek. The shocking picture of the spaceship “flying out” stimulates people’s senses and attracts the attention of tourists. Similarly, The led display company optoelectronics hosted and provided the 3D naked eye led giant screen in Chongqing The led display company square. The led display company also customized the picture contents of astronauts and orbital crossing buildings for it. The dazzling effect attracted tens of thousands of citizens to punch in. However, it is not difficult to see that the content of these pictures is still small compared with the amount of video resources in Shanghai.
The main reason for the lack of resources for these specific pictures is that these contents are too difficult to produce, the cycle is long, and there are few teams specializing in the production of such contents in the market. For the production of 3D naked eye video material, the main viewing angle needs to be selected from the audience’s perspective. At the same time, the three-dimensional structure is made according to the perspective relationship of the display shape of the on-site LED display screen, and the video content is customized point-to-point according to the resolution, so as to ensure the best display effect of the video. This is a fine project, which can also be said to take into account the dual cooperation of art and science and technology.

Such video works with both cultural connotation and high-tech content need professional video modelers and content selectors in the team. However, at present, this kind of market has not developed, or the market in the subdivided field of differentiated screen is still in the development stage. It is noted that the population volume of this market is still small. At present, the production of such video content in the market is still dominated by dazzling technology, with a sense of science fiction and future. The screen shape is also gorgeous and changeable, but the display content integrating urban style and cultural connotation is still very scarce.
This is still in the case of taking the naked eye 3D LED display screen as the carrier, and the curvature and shape of the screen are not exaggerated enough. Some special-shaped screens, such as spherical screen and conical screen, are deformed into more unrestrained screens. The video content required by these screens is more scarce, and sometimes there is only one set of video source for repeated playback.

It has to be said that this situation is unavoidable at present. The progress of LED display technology catalyzes the birth of this phenomenon from another point of view. The progress of science and technology has greatly improved the production level of video materials, and also led to the artistry of the structural modeling of LED display screen, which makes the LED screen no longer limited to the traditional flat screen and has more imagination space, which further catalyzes the demand for video content in the LED industry. People who have seen future sci-fi films can contact the relationship between the holographic world and the game warehouse or the game helmet / glasses. Without the game warehouse, the holographic world cannot be loaded, and the construction of the holographic world and the composition of the game warehouse are a necessary prerequisite. The two complement each other and are indispensable.

With the upgrading of LED display technology, the demand for high-quality video content will also increase. In order to further upgrade the display technology, the demand of screen enterprises for such display content will also increase. There is a concept in high school political economics that is very consistent with the relationship between the two: the two commodities can not replace each other and have mutual needs, and they need to be combined to play a role. The two commodities are complementary to each other. The most essential function of LED display screen is display function. The demand for various display contents is the essential requirement of products, especially the display products whose main function is display function, such as 3D naked eye large screen, special-shaped screen, immersive experience hall, visual exhibition hall, etc. With the rise of night travel economy and cultural tourism industry, high-quality LED video content production may become the next market that needs attention and exploration of LED industry.
