LED: Unstoppable Application Trends in Broadcasting Industry

On August 24th - 27th, 2011, the annual radio and television industry event, the Beijing International Broadcasting Film and Television Equipment Exhibition (BIRTV) was successfully held at the Beijing International Exhibition Center. As the most authoritative comprehensive exhibition for radio, film, and television equipment in China, the number of exhibitors, the degree of advancement of exhibits, the total area of ​​exhibitions, the number of visitors visited, and the degree of professionalism in the past two decades have been established. China has always been a leader in the same type of exhibition.

In this exhibition, the application of advanced technologies such as triple play, 3D, and 4K undoubtedly became the focus of the show. But in addition, almost all LED products throughout the venue and outside the venue are highlights that should not be overlooked. With the constant improvement of technical indicators such as LED brightness and light efficiency, the necessary products for LED film and television stage lighting, LED display and other video studios continue to emerge. The radio, film and television industry has also become an important application field of LED products. LED has also become an unstoppable application trend in the broadcast television industry.

The editors visited the exhibition halls and discovered that whether the type of products they exhibited or the booth settings were passed on to the editors was a clear message that the main products were distinctive. Although many exhibitors do not have many types of exhibitions, they have clearly introduced their own flagship products. This has made all visitors have to focus on the main products. This targeted promotion strategy has also received good results. The exhibiting effect of the exhibition also reflects the self-confidence of exhibitors on their products. Into the starlight film and television booth, a LED three-action digital spotlight of “All Lights” attracts the editor’s eyeballs immediately, creating an impulse to understand this product in detail; This kind of concept has been brought into full play. You will find that there are only two products in the Vicence booth. Among them, the LED high score studio wall system occupying the whole wall of the exhibition stand is the most eye-catching.

For the radio and television industry, LED's main application products are LED film stage lighting and LED background display for performances and studios.

LED stage lighting leads the low-carbon trend of film and television lighting As the broadcasting industry has high requirements for technical indicators such as light brightness and luminous efficiency, combined with the fact that LED technology is not very mature, the application of LED film stage lighting has gone from doubt to acceptance to trial Inspection, from the small-scale promotion to the large-scale application process, this process, LED technology and manufacturers have experienced harsh technical verification and test of the broadcasting industry. Fortunately, with the continuous maturation of LED production technology, the advantages of LED stage lighting in comparison with traditional stage lighting have clearly emerged, and their application range has continued to expand and deepen, especially the national advocacy for low-carbon energy conservation. For the radio and television industry with large power consumption, the application of LED is even more unstoppable.

LED technology represents the development trend of energy saving and environmental protection, green and low-carbon. In the field of film and television lighting, although LED lamps and lanterns are still in a stage of perfect development, with their unique principle advantages, they will gradually replace traditional tungsten lamps and lanterns.

LED display studio monitoring market's "darling"

In the context of triple play, with the ever-increasing number and complexity of monitoring signals at the back end of the studio, especially the ever-increasing level of digitization, how to better achieve real-time transmission monitoring of video signals and cooperating with other new digital signal transfer problems? Once again, the challenger has traditional surveillance technology and equipment. This has also become a problem that the broadcasting and TV industry must face and innovate. With the rapid development of video and audio technologies such as 3D, 4K, and triple-play, the matching display terminals should keep pace with the times in terms of brightness, stability, color reproduction, signal processing, and transmission. The large-scale splicing, LED background walls and other technical products that have continuously emerged from major manufacturers are well adapted to the needs of video and audio technologies. It can be said that the big screen industry has played a role in boosting the upgrade of the broadcasting industry.

LED light sources have become popular in the large-screen splicing market due to their rich colors, long life, and simple maintenance, and various manufacturers have also launched their own LED light source background display products.

The Dehao Technology's bringing together the LCD splicing product 47WV30 brought by LG Electronics is the only LED backlight IPS LCD splicing in China, and it also cooperates with Dehao Technology's own brand processors to form a studio monitoring broadcast display system. Its 6.3mm ultra-narrow bezel leading process achieves perfect seamless splicing; LED backlight technology brings higher contrast and better picture quality; and the application of IPS hard screen makes the picture more tough and never "dragging water" "; 178 * 178 view angle, then allow users to get a wider viewing range. It is believed that the launch of the 47WV30 will fundamentally promote the technological innovation of the studio monitoring system.

Guangdong Weichuang launched its high-grade studio backdrop system, which is very mature in its application. The LED light source DLP splicing wall technology adopted by the LED light source can fully meet the broadcast demand of the live broadcast program for all indicators 24 hours a day, and overcome the defects of the past technology in color temperature mode and environment mode. When viewed on the entire screen, the screen has a clear hierarchy, and each detail and outline can be clearly reproduced. The user can experience vivid and delicate colors and image effects, which greatly improves the perfect reproduction of the splicing system in natural colors such as display effect and picture quality. This is a great advantage for the broadcasting and TV market with extremely high color requirements. Tan Anlin, senior manager of Weichuang Marketing Department, stated: “The LED light source has the characteristics of brighter display, strong stability, long service life, zero maintenance cost, and adjustable characteristics. In the industry, these characteristics determine that it will be used by the Radio and TV. In this case, we, as manufacturers, must adapt to this demand of the television station and continue to follow up technically."

As the large-screen display application in the broadcasting and TV industry, the highest-required segmentation market is also the most lucrative market. The broadcasting and television market has also been one of the most intense markets for LED enterprise competition products. In the past, foreign brands occupied a huge share of this area, but with the progress of the domestic LED display industry, this phenomenon is gradually changing. With the continuous improvement of the LED display technology and the continuous reduction of the price, the LED display market will be more widely used in the broadcasting and TV industry.
