How can LED screen companies rise up and seize the high ground in the field of radio and television?

LED display screens have emerged in the field of radio and television as early as ten years ago. In recent years, with the outbreak of small spacing, they have blossomed in the field of radio and television. Nowadays, with the improvement of people’s requirements for visual enjoyment, the digital construction of TV stations has entered a new stage of development. The studios of TV stations have changed from a traditional single background to LED display screens, which are used more and more frequently. The rise has also promoted the market demand for LED display screens used in studios. Facing the blue ocean in the field of radio and television, how should LED screen companies take advantage of the small pitch and seize the high ground in the field of radio and television?

 

LED display helps the studio's digital transformation

 

In order to promote the digital transformation of video, domestic TV stations have introduced LED displays into studios. In the past, LED displays were used as studio backgrounds in the field of radio and television. Now with the construction of virtual studios, the application of LED displays in studios has changed. More extensively. Traditional studios need to arrange the scenes to achieve the program effect. The traditional studios use a single background to run through the main program, while the virtual studio built with LED displays does not require cumbersome scene layout, only need to import the required materials. The virtual background is automatically generated to make the screen display richer and more real and delicate. As LED display screens are widely used in studios, due to the unique needs of the broadcasting industry, relevant agencies have issued "Technical Requirements and Measurement Methods for LED Display Screens for Studios". The introduction of this standard has made it clear to screen companies and users Understanding the standards for the application of LED displays in studios has strongly promoted the application of LED displays in the radio and television application market.

In fact, with the significant increase in the brightness and refresh rate of LED displays, small-pitch LED displays have already occupied part of the market share in the field of radio and television. In recent years, the dot pitch record of LED displays has been constantly refreshed. Small-pitch displays can better meet the resolution requirements of large indoor screens, and can be compatible with high-definition images in multiple formats such as DVD, SD, HD, SXGA+, and so on. At the same time, we can also see that although this market is large, the barriers to entry are also high. The radio and television industry, as a market segment with high requirements for product technical indicators in display applications, is also a lucrative market. It is one of the markets where LED companies compete fiercely. However, due to the rigor of the radio and television industry, users are more interested in large-screen display products. Performance requirements have always been very strict, which has led to the long-term occupation of the radio and television market by DLP. However, with the advancement of LED display packaging technology, the birth of seamless splicing, and the rise of small spacing, DLP has long occupied the market. The inherent pattern of small spacing has been broken, especially the small spacing has been positioned in the high-end market since its birth, and the small spacing itself has seamless splicing and brightness adjustment. Because the small spacing products are spliced ​​by the box, the size can theoretically be The many advantages of infinite, small-pitch products are very suitable for the field of radio and television, and practitioners engaged in R&D and production of small-pitch products also regard the field of radio and television as a high ground that must be seized.

 

What are the obstacles to the penetration of LED displays in the field of radio and television?

 

With the in-depth development of indoor small-pitch LED displays, more and more keen companies are aware of market opportunities and understand that the industry will take advantage of the small-pitch "east wind" to usher in new development opportunities. Spacing the market, in order to cut into the field of radio and television. In the face of such a market with product advantages, why can't LED displays be widely used in the field of radio and television? From a technical point of view, in terms of brightness, traditional studios need to use lighting as an auxiliary during the recording process. The LED display has the advantages of high brightness and self-illumination, but due to the optical response, the surface of the screen during long-term shooting Reflective light spots including moiré will be generated. How to suppress moiré is one of the problems that LED screen companies must solve in the R&D studio of LED display products. With the increasing and complexity of the back-end monitoring signals of the studio, especially the continuous improvement of the level of digitization, how to better realize the real-time transmission and monitoring of video signals, and cooperate with other digital signal transmission and other new technical issues to challenge traditional monitoring time and time again. Technology and equipment, this has also become a problem that the radio and television industry must face and innovate. Since the control signals of most LED large screen systems are connected in series with LED display boxes, if one of the boxes is broken or there is a problem with the control signal, it will cause all the LED boxes after the broken screen box to lose control. The signal appears partially black. This has a greater impact on the security of live programs. Therefore, the application of LED screens in the live broadcast of the studio should have dual redundancy and dual backup systems. For program live broadcasts, the stability of the display screen is ranked first at all times, and any small failure of the display screen may cause a broadcast accident.

Virtual studio is a unique TV program production technology developed. Its essence is to digitally synthesize the virtual three-dimensional scene produced by the computer and the live image of the character shot by the TV camera in real time, so that the character and the virtual background can change simultaneously, so as to achieve the fusion of the two to obtain a perfect composite picture. The virtual studio system uses camera tracking technology to obtain real camera data and combine it with the computer-generated background. The background imaging is based on the lens parameters obtained by the real camera shooting, so it is completely consistent with the actor's three-dimensional perspective relationship. The feeling of unreal and unnatural. At present, because of its infinite charm and its development prospects that cannot be underestimated, it has been paid attention to by more and more program producers and related personnel. However, the cost of building a virtual studio is high, and the maintenance cost is high and the process is complicated. Many small studios still choose traditional static scenery. A traditional studio mainly uses static wallpapers or static scenery. This method is very cheap, does not require high venues, and is relatively simple to operate. Generally, two cameras and a relatively small space can meet the minimum requirements for live broadcast. Compared with traditional studios, virtual studios that use a large number of LED displays as the display end can be changed freely according to the input material in the background, which greatly enriches the content of the program. Nowadays, with the development of technology, LED virtual studios can remotely communicate with guests. It can also provide first-hand information for the live audience in time to facilitate interactive Q&A needs. It can also create scenes that do not exist or are difficult to produce, and can change the scene in an instant, making it impossible to achieve in a real studio. The effect is that the space is not restricted by physical space, which allows the director to get rid of the constraints of time, space and prop production to a large extent, and obtain a larger creative imagination space.

At present, as the fine-pitch technology becomes more mature and vigorous, and has many advantages, if the cost of the standardization advances over time, LED display products will definitely be widely used in the field of radio and television.

 

It is undeniable that the recognition by users of the radio and television industry for the LED display used in studios is a good for the market expansion of LED display companies. However, it is not a convenient door. After all, there are already many DLP splicing companies, and even LCD companies are here. This area has been occupied for a long time and has the advantage of being a first mover. In particular, DLP splicing companies have rich experience in the radio and television field itself, and have a strong ability to provide comprehensive solutions. The radio and television industry, as a high-standard and strict industry, just pays more attention to comprehensive service capabilities, and the dominant position is not mentioned. Yu. In the face of the rapidly expanding radio and television application market, whether LED display companies can seize the opportunity depends on whether the "internal strength" training is in place. In the future, the application of small-pitch LED display systems in the field of radio and television is an inevitable development trend, and LED screen companies need to seize the opportunity to provide more professional LED display solutions for the upgrading and transformation of radio and television industry studios with better quality and services. , To accelerate the upgrading and transformation of digital radio and television studios.
