Projection screens Draper gains ground with TechVision
Draper describes the projection screen market as becoming inundated with low-cost, low-tech products that are causing further commoditisation. InfoComm has tried to help people to distinguish the quality products from the lower-performing alternatives by introducing the Projected Image System Contrast Ratios (PISCR) standard. As the awareness of the standard grows, so does the desire for more sophisticated projection screens, says the company. Draper’s own answer to this comes in the form of the TechVision, a projection screen that is said to surpass the
industry standard of +/-10% tolerances. For example, the TechVision off ers a 1.8 gain ‘white’ that has no half-gain angle. In other words, as the viewer moves off -axis, there is no point where the gain drops to 0.9 or lower. TecVision, which is available in six varieties, features white surfaces with gains ranging from 1.0 to 1.9 over wide
viewing cones, and grey surfaces helping the screens to perform under higher room light levels. The screen is also 4K ready. The Imaging Science Foundation has certifi ed fi ve of the new surfaces for excellent colour reproduction and fi delity. Draper prides itself on the way the screens aren’t mass produced, but rather individually calculated, programmed, produced, and individually tested and re-tested. Every screen is customised through the use of the Pro Calculator – a tool which the customer can input their requirements to select the best TecVision formulation.

dnp off ers screen depth
dnp puts the success of its Supernova range of projection screens down to technologies that facilitate the production of crisp, front projection images – so that, according to the company, it is no longer necessary to dim the lights even in brightly lit rooms. Available in a wide variety of fi nishes, formats and sizes,
the Supernova range can off er up to seven times the contrast and double the image brightness of standard front projection screens. The Supernova screen material comprises an optical lens fi lm
to reduce the impact of ambient light and thereby ensure better image contrast. Other technologies, such as a refl ection layer, black colour
layer and hard surface coating – which means the screen can provide half-gain angles up to +/- 85º, – enhance colour reproduction as well as making the surface scratch resistant with a no-shimmer image. The range off ers multiple dimensions and sizes, with the
largest screen, the Supernova Infi nity, providing a projection area of any height and width – customised as per the customer’s requirements.

The Fullwhite projection screen from AV Stumpfl is the only surface, according to the company, which shows purely the picture. In other words, borders and unused screen depth aren’t visible when the screen is in operation. The secret to the Fullwhite’s ability to ‘fl oat’ lies in the frame of the screen, which is
designed to remain hidden from sight while off ering the appropriate degree of support. The material is fi xed over the sloping 45º profi le of the frame so that it seems to disappear behind the screen. Vinyl surfaces can be stretched easily and attached to the frame with especially developed hooks on the rear. The screen gives the illusion that the projected image is fl oating in mid-air when installed
in fl ying applications. This makes it an attractive option to architects and for environments that rely on aesthetics as much as, if not more than, AV. Adding further feathers to its cap is the screen’s ability to be connected together to make complete walls or even cubes, off ering multiple display options in a given environment. The Fullwhite
can also be made to measure since its modular system consists of a basic frame that can be sized to any format by adding or removing plug elements – a principle that has been successfully used on the company’s Vario mobile projection screens for many decades.

Regardless of how good the projector is, a quality projection surface can make all the diff erence, writes James McGrath
