TECHNOLOGY: SHOWCASE Projection screens
What’s a projector without an advanced screen to display the device’s output to the best advantage? asks James McGrath

dnp’s screens move with the times
Next-generation 4K resolution (4,096 x 2,160) is a hot topic in the AV industry. With the large-scale uptake of 3D visualisation technology in professional AV applications proving to be slower than many had hoped, 4K offers a more realistic prospect for the development of visualisation devices such as projectors. Elite Screens’ Peregrine
AcousticPro 4K projection screen (and its curved counterpart, the Lunette AcousticPro 4K) has been designed for compatibility with next-generation 4K sources while providing audibility through an
acoustically transparent material. Available from the company’s CI integrator channel, Elite Prime Vision (EPV), the fixed-frame solution uses a 1.1 gain matte white angular woven AT fabric. This incorporates a high-density weave to meet the demands of projection up to 4K resolution without a moiréeffect. In addition to its visual
performance characteristics, sound breathes through the material with little damping: between 0.91dB and 3dB at 20kHz test frequency. The frame of the screen is
manufactured from high- quality anodised aluminium
and is velour coated – this is said to absorb glare and enhance perceived contrast. The screen is also said to
be easy to assemble and install thanks to its sliding wall mounts, ‘fix plates’ – small plastic clips that hold the material in place without mismatching connections – and a precision-fitting frame. The screen comes in a choice of sizes from 84in to 176in (Lunette up to 250in in Cinemascope aspect ratio), and is available in EPV’s Peregrine line of fixed and curved frame projection screens in either HDTV or Cinemascope aspect ratios.

Modern display applications require aesthetically pleasing solutions that blend neatly into their environments. For example, high-end boardrooms and home theatres often require a tidy, minimalist appearance so as not to detract from the attention to detail that has gone into the interior design. The Supernova Blade from dnp is an ultra-thin frameless version of the company’s Supernova Screen, using the ISF-certified Supernova 08-85 screen material. Its 3mm thickness and frameless design combine to provide an eye-catching screen that ensures the picture from the projector is the only visible thing. It can be installed in either of two ways: wall mounted, so it resembles a window, or suspended from the ceiling to give it the appearance of floating. dnp makes the Supernova Blade in three sizes – 100in, 110in and 120in in a 16:9 aspect ratio – meeting
modern-day requirements for wider, flatter screens, says the company. Custom sizes are also available. Performance-wise the
screen still packs a punch despite its minimalist characteristics. A built-in optical filter in the screen’s material absorbs ambient light and enhances image contrast, purportedly delivering up to seven times higher contrast than conventional front-projection screens. This level of performance enables the screen to work well before dusk and in situations where ambient light is necessary, such as to enable meeting attendees to see what they’re reading. As well as offering a neat solution for boardrooms and home theatres, the Supernova Blade can also provide a suitable canvas for exhibitions, university auditoriums and retail environments.

{} Habitech provides a simple and versatile Projecta screen
Quicker and more efficient screen installations can provide profitable results for integrators, according to Habitech. One product in the UK distributor’s portfolio is Projecta’s Tensioned Descender Electrol. The screen is constructed
in two separate parts: the casing can be supplied to on-site contractors for installation at the first-fix stage of construction; the more expensive screen assembly and motor can be supplied later, once the

screen size and any other custom considerations have been finalised. Both the motor and the screen assembly remain accessible for any fine-tuning adjustments or routine system maintenance throughout the lifetime of the product.
Habitech points out that
the screen does not intrude on the acoustics and aesthetics of a room. The near-silently operating motor is 30% quieter than standard tubular motors,
while the casing is housed almost invisibly inside the ceiling, sitting flush with the surface. Despite this, easy access for maintenance is assured as the lid of the casing can slide off to reveal the inner components.
The tab-tensioned screen
is fully customisable with a range of screen fabrics and powder-coated screen finishes. For instance, the Matte White fabric option would suit many home cinema environments with
good ambient light control, offering a 120º viewing angle. Meanwhile, the High Contrast Cinema Vision
fabric would support applications that require
improved contrast and black levels, while for installations where a more realistic soundstage is required, Projecta’s HD Progressive 1.1 Sound screen fabric allows for the placement of speakers behind the projection surface: specially designed perforations allow sound to pass through the material.
