As the production of content such as movies, TV series, advertising and live broadcasts continues to develop towards digital and immersive directions, virtual production is becoming a new trend in film and television production. Against this background, high refresh rate LED screens are playing an irreplaceable role as key components in virtual shooting. This article will conduct in-depth analysis of the technical needs of virtual production for LED displays, especially the importance of high refresh rates, and the application trends of such display technologies in the global market.
- Core technical requirements for LED screens in virtual production
Virtual production combines LED background walls and real-time rendering technology (such as Unreal Engine) to simulate complex scenes, thereby reducing the cost of post-production green screen synthesis and improving shooting efficiency and realism. In this process, LED screens are not only the "background image", but also the dominant player in dynamic light sources and on-site atmosphere. Virtual shooting + LED display reshapes film and television creation!
In virtual production, LED displays usually need to meet the following core technical indicators:
High refresh rate (≥3840Hz)
The higher the refresh rate, the less the picture flickers. It is especially suitable for high-speed photography (such as 120fps) or mobile shooting scenes, which can avoid image problems such as ripple and black bars.
High grayscale and high contrast
Delicate dark performance is crucial to the authenticity of virtual scenes, and grayscale performance directly affects color restoration and light and shadow effects.
Low latency and high frame synchronization
Frame Sync with the camera can ensure that the captured picture is consistent with the screen playback content in real time, improving synthesis efficiency.
HDR and wide color gamut support
When it is necessary to create special effects light and shadow, extreme weather or interstellar scenes, HDR capabilities make the picture more realistic and deep. How to achieve Hollywood-level color restoration on LED virtual shooting screens?
- Why do high refresh rate LED screens become the core?
In traditional LED applications (such as advertising and information display), the impact of the refresh rate is mainly on the naked eye's view and anti-interference ability; while in virtual production, the high refresh rate directly determines the "photoability" of the picture. If the refresh rate is not enough, even if the problem cannot be seen with the naked eye, the pictures taken by the camera will have scan lines, strobes, color drifts, etc., which greatly reduces the quality of the content. Here is the XR LED Background Wall: High Frame Rate and Low Latency Optimization Guide.
For example, when shooting LED background movies, the leading international film and television production companies usually choose screens with a refresh rate of no less than 7680Hz to cope with high-speed camera needs and complex multi-camera shooting processes.
- Global market trend: demand for high refresh LED screens continues to rise
According to data released by market research company Omdia, the global LED virtual shooting market size has exceeded US$1.5 billion in 2024, of which the screen-to-body ratio of high refresh rate LED displays exceeds 60%. Especially in large production institutions such as Hollywood, the British Songlin Studio, and South Korea's CJ ENM, high refresh COB/Mini LED screens are becoming the mainstream.

Chinese LED screen companies such as Leyard, Zhouming Technology, SoStron, Abbisen, Lehman Optoelectronics, etc. are also actively planning virtual shooting tracks, launching "small-pitch LED screens" or "XR virtual shooting solutions" with high refresh rate and high contrast to serve domestic and foreign crews and studios.
- Procurement suggestions and selection references
For virtual production users or studio purchasing personnel, it is recommended to focus on the following parameters when selecting LED screens:
Refresh rate: at least 3840Hz, recommended 7680Hz and above
Grayscale: above 14 bits, which helps restore low-bright scenes
Pixel spacing: P1.5 or less to meet close-up HD shooting
Control system: Support Genlock frame lock function
Width brightness adjustment range: compatible with different light scenes
At the same time, the supporting rendering server, graphics synchronization system and photography lights should also match the performance of the LED screen to build an integrated virtual shooting system.
Conclusion
High refresh rate LED screens are becoming an indispensable and important infrastructure in virtual production. From a technical perspective, it not only improves the quality of content shooting, but also promotes changes in film and television production. From a market perspective, the growth of global film and television industry and virtual shooting demand will continue to drive the iteration and application of high-performance LED displays. In the future, with the reduction of technical thresholds and cost optimization, the penetration rate of high refresh rate LED screens in virtual shooting, digital stage design, online live broadcast and other fields will continue to increase, becoming the visual engine in the digital imaging era.
