Da-Lite 28851V 109" Parallax Pure Screen

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 28851V 109" Parallax Pure Screen-ALR is an innovative projection screen that enhances the visual experience in both professional audiovisual settings and home theaters. Featuring HD progressive surfaces designed for 1080p, 4K, and Ultra HD, this screen ensures stunning image quality with exceptional clarity and detail.

One of the standout features of the Parallax Pure technology is its ambient light-rejecting capabilities. The micro-layered optical lens system in this screen effectively rejects any unwanted light, producing an image that is free from glare and speckles. This means that even in brightly lit environments, you can enjoy high-contrast, bright images without any distractions.

The Parallax Pure surface is designed to mimic the look of a television, whether it is turned on or off. This creates a seamless integration with your viewing experience, enhancing the immersion and realism. Additionally, the surface is flexible, allowing it to be shipped in a roll and easily installed in any space.

The construction of the Parallax Pure screen involves multiple layers that play a specific role in preserving the image in high ambient light environments. Some layers absorb light while one special layer is shaped like a microscopic saw-tooth, blocking light from above. This unique design ensures that the screen maintains its image quality even in brightly lit spaces.

Unlike regular screens, which reflect light uniformly in all directions, the Da-Lite 28851V 109" Parallax Pure Screen-ALR is an ambient light rejecting screen. It selectively reflects light back toward the viewer, resulting in a brighter image within a certain viewing angle. This means that the projected image will reflect back to the audience at the mirror-opposite angle to the projector hitting the screen, maximizing brightness and clarity.

It is important to note that the ambient light source must be coming from a different direction or angle than the projector for the ALR screen to be effective. The screen is fire retardant and mildew resistant, ensuring its durability and longevity. Standard wall-mounting brackets are included for easy installation.

With its exceptional image quality, glare-free surface, and innovative ambient light-rejecting technology, the Da-Lite 28851V 109" Parallax Pure Screen-ALR is the perfect choice for anyone looking to enhance their viewing experience in any setting. Whether you're watching movies, giving presentations, or gaming, this screen will deliver stunning visuals that captivate and impress.
