Da-Lite 28845V 100" Parallax Pure Screen-ALR
Overview
Features HD Progressive surfaces designed for 1080p, 4K and Ultra HD! Ambient Light Rejecting Material!
Parallax Pure is an ambient light-rejecting technology that features a micro-layered optical lens system that rejects light. This new technology mimics the look of a television when it is on and when it is off, but without the glare from windows or lighting fixtures. With extremely wide viewing angles, no speckle and no glare, the surface is ideal for applications in Pro AV as well as Home Theater. Additionally, the surface is flexible, ships in a roll and is easy to install. Each layer of Parallax Pure plays a role in preserving the image that is reflected back to the viewer in high ambient light environments. Some layers absorb light while one special layer is shaped like a microscopic saw-tooth that blocks light from above resulting in the preservation of high-contrast, bright images in brightly lit environments.
Ambient Light Rejecting (ALR) screens differ from a regular screens in several ways. The most common screen surfaces reflect the incoming light uniformly in all directions.
These screen surfaces are referred to as diffuse reflectors. The light is reflected back in many angles, rather than just at one angle. Surfaces that reflect back at only one angle are referred to specular reflectors - they reflect light at an angle precisely opposite the one at which that light arrived, such as a mirror.
Some projector screens may not be purely diffuse reflectors in the sense that they may reflect light back in one direction more than other directions. This is often done to increase the brightness of the reflected image (gain) within a certain area (viewing angle).
An ALR screen works by selectively reflecting light back to the audience. This effect is achieved by positioning the projector and screen in such a way that the projector's light is bounced towards the audience, while the other light in the room is reflected back in some other direction.
Some ALR screens work due to a principal referred to as Angular Reflectivity. This means that your projected image will reflect back to the audience at the mirror-opposite angle to the projector hitting the screen. I.e. if the projector is angled down at a 15 degree angle, the audience will get the brightest image while viewing the screen looking up at 15 degrees.
Whichever the ALR technology that your surface is using, there will still be some ambient light that cannot be negated. ALR screens only work if the ambient lighting is NOT hitting the screen from the same direction the projector. I.E. if you have your projector positioned at the back of the room near other light sources that are also aiming towards your screen, the ALR surface will not do anything to negate that other lighting.
The ambient light source must be coming from a different direction/angle than your projector such as reflections off of white walls, overhead or recessed lighting or from windows on the side of your room in order to get the benefit of an ALR screen.
It will be fire retardant and mildew resistant, plus standard wall-mounting brackets will be included.

The Da-Lite 28845V 100" Parallax Pure Screen-ALR is a revolutionary piece of technology that will enhance your viewing experience. Designed for use with 1080p, 4K, and Ultra HD projectors, this screen features HD progressive surfaces that deliver stunning image quality.
What sets this screen apart is its ambient light-rejecting technology. The micro-layered optical lens system effectively rejects light, eliminating glare from windows or lighting fixtures. This technology creates a TV-like viewing experience, both when the projector is on and when it is off. With wide viewing angles, no speckle, and no glare, this screen is perfect for both professional audiovisual applications and home theaters.
The Parallax Pure surface is not only high-performing but also extremely flexible. It ships in a roll and is easy to install, making the setup process a breeze. Each layer of Parallax Pure contributes to preserving the image quality in high ambient light environments. Some layers absorb light, while one special layer is shaped like a microscopic saw-tooth, effectively blocking light from above. This design preserves high-contrast, bright images even in brightly lit surroundings.
Unlike regular screens, the ambient light-rejecting screens work by selectively reflecting light back to the audience. This means that the projector's light is directed towards the audience, while other ambient light in the room is reflected away. Whether it's achieved through Angular Reflectivity or another ALR technology, the result is a clear and bright image for the viewers.
The Da-Lite 28845V 100" Parallax Pure Screen-ALR is not only high-performing but also durable. It is fire retardant and mildew resistant, ensuring years of reliable use. The package includes standard wall-mounting brackets, making the installation process even more convenient.
Key features of this screen include the Parallax Pure surface options for different throw projectors, micro-layers that block and absorb light, glare and speckle-free viewing experience, easy installation, and a standard frame with Pro-Trim® finish to absorb surrounding light.
Upgrade your viewing experience with the Da-Lite 28845V 100" Parallax Pure Screen-ALR. Whether you're watching movies, sports, or presentations, this screen will deliver exceptional image quality, even in brightly lit environments. Experience the future of projection technology with this innovative product.
