Da-Lite 28844V 92" 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 28844V 92" Parallax Pure Screen-ALR is an innovative product that enhances your viewing experience by providing an optimal display in brightly lit environments. Unlike regular screens, this ambient light-rejecting technology features a micro-layered optical lens system that rejects light, mimicking the look of a television whether it is on or off. With the elimination of glare from windows or lighting fixtures, you can enjoy a clear and vibrant image.

One of the standout features of this screen is its flexibility and ease of installation. It ships in a roll, making it convenient to transport and assemble. Each layer of the Parallax Pure surface plays a role in preserving the image that is reflected back to the viewer in high ambient light environments. Some layers absorb light, while a special microscopic saw-tooth layer blocks light from above, resulting in high-contrast, bright images even in brightly lit spaces.

Unlike regular screens that reflect light uniformly in all directions, the Parallax Pure screen selectively reflects light back to the audience. This is achieved by positioning the projector and screen in a way that the projector's light is directed towards the audience, while other light in the room is reflected away. This advanced technology ensures that you get the brightest image possible.

It is important to note that ambient light-rejecting screens work best when the ambient lighting is coming from a different direction than the projector. This means that if your projector is positioned near other light sources that are also aiming towards the screen, the ALR surface will not effectively eliminate the additional lighting. To fully benefit from the ALR screen, the ambient light source should come from a different direction or angle, such as reflections off white walls, overhead or recessed lighting, or windows on the side of the room.

The Da-Lite 28844V 92" Parallax Pure Screen-ALR is designed to be fire retardant and mildew resistant, making it a durable and reliable choice. The package includes standard wall-mounting brackets, ensuring easy and secure installation.

Experience the next level of viewing with the Da-Lite 28844V 92" Parallax Pure Screen-ALR. With its HD progressive surfaces designed for 1080p, 4K, and Ultra HD, this screen delivers immersive visuals with no glare or speckles.
