The 1,800 cd/m2-capable B-series was developed with Sony Pictures specifically for use as a studio backdrop without showing reflections, while the C-Series is more for installation in lobbies or showrooms. They use the same processing as Sony’s TVs, with the ability to handle HDR, 120 fps and 3D video sources.

Still, finding more uses for the technology, which uses ultrafine LED elements mounted to each color for practically unmatched contrast, could make it slightly more realistic for installation in a home theater setup.
