Abbison joins hands with Bocai Media to make the world's largest single LED virtual studio debut

At a time when film and television production technology is rapidly innovating, an industry-shaking achievement has emerged. Recently, the world's largest single LED virtual studio jointly created by Abison, the world's leading brand in LED display technology and applications, and Bosch Media, quickly attracted the attention of inside and outside the industry as soon as it was unveiled, triggering widespread heated discussions.
Since 2019, Abison has been very forward-looking in the technical fields related to virtual production and resolutely launched the research and development journey of the first generation of products. After six years of unremitting research and innovation, products continue to be iteratively upgraded. This time, the Bocai virtual film and television base is the epitome of its latest technological achievements, fully demonstrating the strong technical strength of China display companies in the field of high-end film and television production.

Breaking through spacing accuracy and leading the industry to leap forward

The product spacing for this virtual studio application is P1.8. This value may seem ordinary, but it is actually of great significance. With its strong technical research capabilities, Abbison has achieved the spacing accuracy of ultra-large-area virtual studios below 2mm for the first time in the industry, successfully breaking the existing pattern of the industry and pushing the entire industry to take a big step forward. Abbison CTO Shi Changjin pointed out that the current spacing of LED virtual studios on the market is generally above P2.5, but Abbison's team has faced the difficulties and achieved large-scale application of P1.8 spacing products. This achievement means that 600 million pixels of point-to-point real-time driving can be achieved, achieving the ultimate effect of zero-delay real-time rendering, allowing the camera to zoom in to only 2 meters away from the screen to shoot, providing film and television creators with more flexibility and diversity. Shooting perspective and creative space.

Strict testing standards,

the key essence of virtual shooting to create extreme display performance is what you see is what you get, which puts forward almost stringent requirements on the display performance of the product. In order to meet the ultra-high standards of film content production, Abbison adhered to a rigorous attitude during the project implementation process and carefully organized three large-scale tests from the initial plan design to the final project acceptance. The test content covers the technical indicators of each key dimension of the display, including the realization degree of small spacing, high resolution, and high precision; whether the color gamut requirements in different color spaces meet the standards and how the color temperature accuracy is; whether there is any deviation in gray scale display accuracy in different color spaces; whether high frame rate and high refresh rate can be stably presented; the optimization effect of moire and twill during close-up shooting; and the temperature rise and heat dissipation control status of special greenhouses during operation.
Through comprehensive integration and strict control of world-class standards, Abison products have successfully achieved breakthroughs in multiple core dimensions. In terms of improving HDR image quality, the details of the picture are richer and the contrast between light and dark is more layered; in the optimization of moire and twill, interference patterns are effectively eliminated, making the captured picture pure and natural; wide color gamut coverage ensures that the colors are beautiful and true, and the degree of restoration is extremely high; excellent viewing angle allows the best picture to be obtained from shooting in different positions;24 - 250Hz full frame rate adaptive function allows you to flexibly adapt the frame rate according to the shooting scene to ensure that the picture is smooth and not stuck. In addition, the signal hot backup dual card dual standby design is the first application in the global virtual shooting field. It adds dual insurance to stable signal transmission during the shooting process, greatly reducing the risk of shooting interruption due to signal problems.

Overcoming engineering problems and ensuring stable operation of studios

Abison's products and solutions not only meet film-and-television production standards in terms of display performance, but also demonstrate excellent innovation capabilities in the engineering implementation of ultra-large LED virtual studios, successfully overcoming many problems. This giant LED curved screen of over 1700㎡ has extraordinary strict requirements for load bearing and flatness. Through many simulation tests and optimization adjustments, Abbison's team finally accurately controlled the flatness deviation of the entire screen to within 3mm, and the left-right deviation of the back strips of the steel structure to within 1 cm, ensuring that the giant screen would not produce visual flaws due to structural problems, providing a stable and flat background for film and television shooting.

When such a large-area LED screen is operating at full power, heat dissipation becomes a difficult problem in front of us. Abison service engineers who participated in the project revealed that the project team cleverly divided the entire screen into 54 small areas, carried out targeted heat dissipation design based on the different location, power consumption and other factors of each small area, and carried out point-to-point precise wiring. At the same time, relying on the advanced dynamic thermal correction system, the temperature of each area of the screen is monitored and adjusted in real time to ensure that the entire screen will not affect the display effect due to uneven heat dissipation, and always maintain the consistency of image quality during the shooting process, creating a stable and reliable shooting environment for film and television creators.

Strictly abide by safety standards and escort film and television creation

in terms of safety such as waterproof and fire prevention, the Abbison LED display used in the studio has reached IP41 protection level and successfully passed the national 3C safety certification. It can fully meet the various special requirements in the film and television content production process. The shooting needs of scenes, whether it is in humid environments or scenes involving pyrotechnic special effects, can operate safely and stably. In addition, the product has also passed a series of international authoritative certifications such as CE, RoHS, FCC, and UL. It has comprehensively benchmarked the highest standards in major markets around the world in terms of quality, safety and compliance. It has used excellent product quality and safety performance to provide film and television filming. Protect.
From the early generation of products in 2019 that successfully replaced the traditional green screen with LED displays, opening a new chapter in virtual shooting, to the second and third-generation products that gradually overcome the compatibility problems of different color gamut space standards, achieve high frame rate improvement and optimize moire, etc., to the fourth-generation products achieving a qualitative leap in technical performance, Abbison has always led the industry's development trend. Shen Chenqi, general manager of Bocai Media, said with emotion when reviewing the cooperation process with Abison. From the 150-million-pixel product it cooperated with for the first time, all the way to the ultra-large studio with 600 million pixels today, Abison can always accurately capture customer needs and transform them into practical technological breakthroughs.

The successful construction of the world's largest single LED virtual studio not only sets a new benchmark for the field of LED virtual production, but also demonstrates to the world the strong innovative strength of China display companies in the digital transformation process of the film and television industry. As virtual shooting technology becomes increasingly mature and application scenarios continue to expand and enrich, Abison said that it will continue to increase investment in research and development, accelerate the pace of technology iteration, and strive to provide higher-quality display products and services to film and television content creators around the world., fully accelerate the commercialization of virtual shooting and inject a steady stream of new impetus into the prosperity and development of the film and television industry.
