It seemed like most screen companies were highlighting ambient light-rejecting (ALR) screens at CEDIA this year. Seymour-Screen Excellence showed its new Ambient-Visionaire material, which is available with three gain values: 1.2, 1.3, and 2.1. The 1.3 version has a 70° half-gain angle—Chris Seymour calls this version the videophile's ALR screen—while the 1.2 version (pictured above) has a 45° half-gain angle. Notice that the left side of the screen is darker than the right side, which is at a shallower angle to the camera. The company claims there is no color shift at any angle, which seemed to be the case.
The material includes a layer of randomly oriented nanomirrors—over a billion on the surface of the 120" (diagonal) demo screen seen above. Seymour-Screen Excellence claims this is a more-efficient way to filter ambient light than other approaches, and it eliminates sparkles. In addition, carbon particles between the mirrors absorb light, which, along with a dark substrate, results in a dark gray screen when no image is being shown.
Randomly oriented nanomirrors cover the surface of the Ambient-Visionaire material, surrounded by carbon particles, all on a light-absorbing substrate.
This is a very interesting approach to ALR screens; I hope to get Chris Seymour and his French counterpart at Screen Excellence on the Home Theater Geeks podcast to talk about it in more depth.
