This white paper explains how LED displays are transforming virtual production in film and TV by replacing green screens with real-time, immersive backdrops. Productions like *The Mandalorian* use massive LED walls to render dynamic environments, enabling better lighting, faster scene changes, and reduced post-production costs. Directors can view and adjust effects live, eliminating expensive reshoots. Challenges include scan-line artifacts, color loss, and flicker at low brightness, which can be mitigated by matching camera exposure with LED refresh rates. Macroblock driver ICs address these issues, supporting 120 FPS and 7,680 Hz refresh, ensuring seamless, cinematic results.
