The superb video performance of the Reference series screen comes from EluneVIsion’s R&D efforts in creating a material that is 100% transparent to the user, and designed for maximum detail clarity when used with 1080p and 4K projectors. The material is a near perfect lambertian diffuser, which means that the light is dispersed evenly in a hemispherical distribution, allowing for a balanced and smooth light reflection. The smooth and even light reflection means that there is no hot spotting and or texturing. Furthermore, the material provides a near perfect white field uniformity and an extremely large viewing cone.
Our Reference Studio 4K Tab-Tensioned motorized screens have a very long expected life of 15-20 years, due to the use of our Pure Flat Tab-Tensioning system, which involves the use of a large asymmetrical roller tube, heavy weight bar, and precisely tensioned tabs at the sides of the screen. This long life, combined with our Reference Studio 4K 100EL material that performs at the studio/reference level, ensures that this screen can be used for many iterations of projector upgrades.
The projector technology today is advancing by leaps and bounds, which means that every 3-4 years is the optimum time to upgrade your projector. Because our screens perform at the highest level, you will be able to enjoy each improvement in performance to the fullest level on the Reference Studio 4K screens. All but the most expensive competitors are currently unable to fully support a 1080p image, which means by purchasing a non-Reference screen, you are effectively wasting the performance of your 1080p projector.
Due to our texturless surface and lambertian design, even when the resolution eventually increases to 4K pixel resolution, each pixel will be rendered accurately. Our competitors’ non-Reference class screens effectively down-sample today’s high-resolution 1080p projector to a lower-resolution image (as you will see in the tests/demonstration images below), and they will do it even more for tomorrow’s higher resolution 4K projectors. Whether you are purchasing a screen to get the most performance out of your projector today, or you are purchasing a screen that will work with video resolutions of tomorrow – the Reference Studio 4K series is the best solution.
The Reference Studio 4K series of screens is designed to maximize detail, resolution and uniformity for both 2D and 3D projection. To get the best 3D immersive experience, the screen must be free from artifacts, hot spots and textures. Any flaw in the material and in the reproduction will contribute to a loss of immersion and viewer fatigue due to increased cross talk.
At EluneVision, much effort was spent designing a projection material that is texture free. The result is the Reference Studio 4K 100EL material, which is completely free of texture, giving a completely smooth and pit free surface. EluneVision Reference Studio 4K screens have the highest clarity, sharpness and definition of any projection screen released to date. This means, simply, that the geometry of each projected pixel remains as the projector manufacturer intended.
To illustrate this point, see the screen material texture comparison below, showing our Reference Studio 4K 100EL material beside Stewart’s (widely considered the gold standard, but at a much higher cost), as well as two other more expensive competitors.
The lack of texture leaves pixel geometry perfectly intact with our material. Why is this important? With 1080p projectors now standard and 4K projectors becoming more affordable, EluneVision’s Aurora 4K UHD material ensures that the effective resolution remains at 1080p, while other (more expensive) competitors degrade the pixel geometry to the point that the effective resolution is no longer even close to 1080p. Also due to the fact that there is zero texturing and perfect preservation of detail clarity, the Aurora 4K UHD material will perfectly resolve 4K and 8K resolution, saving you a screen upgrade and thus saving a lot of money.
Due to the use of a smooth and, our screen has absolutely no sparkles. The Aurora 4K UHD material will easily pass any of the common sparkle tests, which include fast action bright scenes in movies as well as hockey, footbal, and other sports. This means that viewer will always see the image displayed on the screen as the projector manufacturer intended, and will never see the annoying imperfections present on competitors’ screen materials.
When an image’s pixel pattern does not match that of the textured surface it is displayed on, moire is created. The mismatch causes a wavy, non-uniform, interference pattern which degrades projected image quality and uniformity.
The Aurora 4K UHD material completely eliminates this problem because the screen material is texture free, which means that there is no textured surface pattern that could cause the creation of the interference patterns. Furthermore, the Aurora 4K UHD material has been tested with LCD, DLP, D-ILA and SXRD projectors to ensure a moire-free picture at various throw distances and viewing angles.
To the left is an example of how moire can impact picture quality. When you zoom in, you see that the competitor’s screen creates moire on the woman’s dress, causing artifacting patterns that are not supposed to be on the image. Furthermore, the moire pattern also causes discoloration, as green hues are introduced on what is supposed to be a completely blue dress in the competitor’s image.
At EluneVision, we believe the perfect screen is one where you never notice the screen surface under any conditions. In many poorly designed projection materials, the screen texture and surface will become visible to the viewer, taking away from what is being projected. In order to design a material that can be called Reference, we engineered a material that is a near perfect lambertian diffuser.
The surface of a material exhibits Lambertian reflectance if the viewer sees the same image or brightness regardless of the viewer’s angle. From a more technical perspective, this means the incident light is scattered in all directions equally. A good example of this is an unfinished block of wood, where no matter what angle you view it, the luminance is roughly equal. In contrast, finished wood with a glossy coat of polyurethane exhibits specular highlights, which are areas of brighter luminance when viewing at different angles. While this glossy finish may be beneficial on furniture, it is the cause of numerous problems in projection screens.
A big problem that you see with all but the best screens is an issue known as hot spotting. Hot spotting is described as an area of the screen where, instead of acting like a perfect diffuser of light, the screen acts as a mirror, i.e. reflects the light back in-line with the conical light path of the projector. The end result of this is an area at the center of the screen with high glare and light, surrounded by too dark of an image at the top, bottom and sides of the screen. As seen below, this results in a very unnatural image. Note: this is not a phenomenon that only cheap screens suffer from – Stewart’s much more expensive Firehawk Reference G3 screen severely suffers from this problem, for example, serving as a testament to the high quality and attention to details of EluneVision’s materials engineering team.
Reference Studio 4K 100EL material provides perfect white field uniformity due to the material’s lambertian diffuser nature. The brightness will be even across the entire screen and there will not be areas of the screen which are brighter or dark to the viewer at any viewing angle. When projecting a pure white scene, the white level will be even from edge to edge, with absolutely no hot-spotting or texturing, demonstrating a reference level of performance and image quality.
EluneVision’s new Reference Studio 4K 100EL material is designed specifically to achieve the highest level of colour reproduction. To achieve this, the material is designed for a completely neutral colour reproduction. The lambertian diffuser property, in addition to a specially designed white base colour, maintains colour accuracy across the entire colour gamut. Many other projection materials in the market today will exhibit a shift in hue, either to the blue, green or red. This creates an unnatural balance to the colours and will decrease the colour uniformity and vibrancy.
Above, we see a demonstration of this phenomenon. The top zoom-in shows the competitor’s screen versus our EluneVision Reference Studio 4K screen. Note the color shifts that the competitor exhibits, as well as the minimization color shifts of the EluneVision Reference Studio 4K 100EL material. This results in the color accuracy of the whites and the reds you see in the EluneVision Reference Studio 4K image.
Due to the near perfect lambertian diffuser properties of the Reference Studio 4K 100EL material, the viewing angle is a full 180 degrees, allowing seats to be placed off axis without any changes in brightness or white field uniformity. The image on the Reference Studio 4K material is consistent from edge-to-edge at all viewing angles.
To demonstrate this, photos were taken and posted below (the images were not re-touched). The first one shows a projected movie in a front view, while the second shows the movie at fairly extreme side view. Though the user would not normally sit this far off center, the photos below demonstrate the fact that in any way that you decide to arrange seating, the screen will perform with perfection from any view-point. This performance extends to the height and location that you decide to mount the projector. Whether ceiling mounted and centered to the screen, or table mounted to far to the left/right of the screen, the image the screen projects back to the viewer will not degrade.
EluneVision Reference Studio 4K Tab-Tensioned motorized screens use our specially designed tensioning system known as Pure-Flat Tensioning system. The first stage of our Pure-Flat Tensioning system involves using an extremely heavy weight bar at the bottom. The bar is made of solid steel and its weight ensures that the screen is under great tension in the vertical direction, thus eliminating swaying from vibrations or moving air.
The second stage of the tensioning system involves the use of tensioned tabs at each side. This system allows tension to be applied horizontally, ensuring a flat surface. Our specially designed system ensures a smooth flat surface and prevents curling. Year after year, the screen will be flat and wave free.
For the video connoisseur who needs a motorized screen, the only choice would be a tensioned screen, as flatness is key to preserving the media as it was meant to be seen. A surface that is wrinkle-free and without any distortions is the ideal to which a movie will be projected. This is where the Pure-Flat Tab-Tension system really shines.
The screen material is rolled onto a large diameter roller tube, making the screen surface flatter, as there is less curvature in the material when it is rolled up, versus the smaller roller tubes commonly employed by most screen manufacturers.
In order to bring you a flat picture, major design innovations had to be employed in the design and engineering of the screens:
– As the fabric is rolled into the roller tube, where the fabric first meets the tube will cause a slight indentation that will repeat at regular intervals across the material. This problem is solved by using a symmetrical roller tube with a grove for where the material is first placed into. This ensures there are no repeating horizontal indentations in the material.
– The Reference Studio 4K 100EL fabric is slightly elastic and therefore works perfectly, as it can be tensioned to create a perfectly flat canvas for your movies.
– An extremely heavy weight bar is used as the bottom bar. The bar is made of solid steel, to ensure that the screen is under great vertical tension and eliminates swaying from vibrations or air movement in the room.
The tensioning system involves the use of tensioned tabs at each side. This system allows tension to be applied horizontally ensuring a flat surface.
– The tension of the screen can be adjusted using adjustment knobs located at the end of the bottom bar.
Professional All-Aluminum Housing
The Reference Studio 4K series screens have a sleek, matte black aluminum housing that is both durable and attractive.
Our heavy-duty housing allow easy access to screen components and installation with a pop-off screen casing cover.
The matte black aluminum frame is made from aluminum and fire-resistant materials.
Support for in Ceiling Installation
The screen is specially designed with RF receiver built into the screen housing. This receiver allows the use of RF remote control and wireless trigger unit. This means that the screen can be hidden away for in-ceiling installations.
Universal Wireless Trigger (Optional)
Numerous screens come with the availability of 12V trigger port; however in many circumstances the conventional 12V wireless trigger may not be sufficient to satisfy all the needs. Introducing the high performance and versatile Universal Wireless Trigger, it is a specially designed wireless trigger for Reference Studio Tab-tensioned motorized screens. The Universal Wireless Trigger is connected by IEC C13 and C14 instead of 3.5mm trigger port, it triggers from the change of power usage through the connect line. Plug this unit between your projector and its power cord and the trigger will memorize the power difference the projector uses between ON and OFF, thus triggering the screen DOWN or UP. This feature is tested and proved reliable with various brands of projectors.
Your projector does not have a 3.5mm trigger port? No problem! The Universal Wireless Trigger is designed to work with projectors without trigger port, and that’s not just it. The Universal Wireless Trigger, can be used on other devices as well, because it uses C13 and C14 power plug instead of 3.5mm trigger port.
What’s more amazing is that, the Universal Wireless Trigger itself is powered by 120V AC instead of batteries, offering exceptional range for up to 50m. The signal is also strong enough to go through household walls and bulkheads, without the worries of changing batteries ever again.
