![]() Read the full technical white paper on Ambient Light Rejecting Screens and the Laws of Physics HERE. As UHD and HDR become common, with 8K (and 16K) on the roadmap, ALR screens like the revolutionary new Phantom™ HALR™ from Stewart Filmscreen will further enhance your viewing pleasure on the big screen. This translates into the ability to produce surfaces that limit ambient light from intruding on the image. ![]() For the 3D fans out there, Phantom retains polarization for linear or circular 3D displays. In high ambient light conditions, with over 50 foot-candles of ambient light directly on the screen, Phantom meets ANSI industry standards. Phantom is equal to the blackest screens available, leading with over 30:1 contrast for a 2,000-lumen projector and 20 foot-candles of ambient light (from several sources) hitting the screen surface at 40°. In other words, it uniformly performs ambient light rejection across the full screen width and height. This provides an even viewing cone, horizontal and vertical, where others tend to favor the horizontal over the vertical. Phantom is unity gain, where competitors are between 0.8 and 1.3 gain. Testing shows that it is inherently compatible with higher resolutions. It is also available in perf configurations. So, you can see a bright picture even in a bright room. First, Phantom is flexible in sizes up to 40’ x 90’, can be placed in a fixed frame, or put in an electric screen enclosure. The Ambient Light Rejecting Screens (ALR Projector Screens) reject the Ambient Light when it falls on the Screen. The new Stewart Filmscreen Phantom™ HALR™ is an example of the current state of the art. If ALR is used as designed, brightness, contrast, and color saturation are maintained or enhanced in the presence of higher ambient light.Īll ALR screens are not equal. As with traditional gain screens, going beyond these angles will reduce the quality of the image on the screen. In most ALR screens, there are specific horizontal and vertical viewing angles that are the “sweet spot” for the viewer. These microscopic filters actively reflect a projected image while diverting indirect light away from the audience. They are uniquely multi-layered, consisting of a molecular layer that acts as an optical filter to eliminate indirect light, positioned below a contrast-enhancing layer. By selectively reflecting ambient light, you can position the screen so that projector light is directed towards the audience, ambient light is slightly absorbed, and reflected away from the audience.ĪLR screens use a combination of optical filters and dispersion to accomplish this. The concept of controlling incoming light and reflecting it at predetermined angles is the basis for most ALR screens. These screens are typically higher gain, causing projector light to be focused back in a narrower viewing cone. Since this allows managing where incoming light is reflected to, ambient light can be directed away from the audience. Incoming light is reflected along a single direction, where the angle of incidence equals the angle of reflection. In higher ambient light situations, this can render the images unacceptable.Īnother screen type is angular reflective. The problem is that any ambient light present will also diffuse evenly, degrading contrast and color saturation. For projection screens, matte white is the “perfect” diffuser, reflecting incoming light at nearly 180°, for extremely wide viewing angles. This means you can look at art on a wall, and from anywhere it looks virtually identical.
