Da-Lite 28850V 94" 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 28850V 94" Parallax Pure Screen is the perfect addition to your home theater or Pro AV setup. This screen features innovative Parallax Pure technology, which is an ambient light-rejecting material that mimics the look of a television when it is on and off, without any glare from windows or lighting fixtures. With its micro-layered optical lens system, this screen rejects light and provides extremely wide viewing angles, allowing you to enjoy your favorite movies and presentations with no speckle or glare.

What sets the Parallax Pure Screen apart from regular screens is its ability to selectively reflect light back to the audience. Unlike diffuse reflectors, this screen reflects light back at only one angle, resulting in a high-contrast, bright image that is preserved even in brightly lit environments. Whether you're using a standard throw projector or an ultra short-throw projector, there is a Parallax Pure surface available for you. The screen is flexible, ships in a roll, and is easy to install.

One important thing to note is that the ambient light source must be coming from a different direction/angle than your projector in order to fully benefit from the ALR screen. If your projector is positioned near other light sources that are also aiming towards the screen, the ALR surface may not be able to negate that other lighting. However, if the ambient lighting is coming from reflections off white walls, overhead or recessed lighting, or windows on the side of the room, you will experience the full benefits of the Parallax Pure Screen.

In addition to its superior performance, the DA-LITE 28850V 94" Parallax Pure Screen is fire retardant and mildew resistant, making it a durable and long-lasting investment for your home theater or Pro AV setup. The screen comes with standard wall-mounting brackets for easy installation, and its standard frame features a Pro-Trim finish to absorb light surrounding the viewing area, further enhancing your viewing experience.

With its HD progressive surfaces designed for 1080p, 4K, and Ultra HD, the DA-LITE 28850V 94" Parallax Pure Screen is the perfect choice for anyone looking to elevate their movie-watching or presentation experience. Enjoy the benefits of an ambient light-rejecting material and immerse yourself in stunning visuals with this top-of-the-line screen.
