It’s for this reason ST is partnering SI to offer this innovation to the Australian market. Through this innovation and products including the Slate range, SI has developed technology that complements Screen Technics’ (ST) product portfolio. The material used in these screens enables a more accurate image representation than a matte white or grey screen in a high ambient light environment. Screen Innovations’ (SI) Black Diamond®, the world’s first and only multidirectional ambient-light-rejecting (ALR) projection screen technology, has been a revolution. This works well and is popular in corporate environments, but it does require a fair amount of real estate behind the screen and for that reason is rarely used in home theatres. Rear projection screens: When the projector is behind the screen in its own dark room and you are sitting in a well-lit room on the other side from the screen.
Projection screens are not really an alternative to televisions.īut there are products supplied by Screen Technics that can assist with ambient light conditions Seek advice.įor the majority of projection screens, the entire theatre room should be as close to dark as possible, as ambient light will wash out the projected image to some extent, and the contrast (the difference between black and white) will diminish. Please note that high gain screens can still have some limited commercial applications. Unity gain disperses the reflected light in multiple directions and this achieves evenness of brightness across the entire screen and has no artificial artifacts interfering with the projected image. But with new, powerful projectors, there is no need for brightness assistance, so why put up with hotspotting? High gain screens always had a hotspot (bright circular centre) with fading brightness at the edges of the screen, which people used to tolerate to achieve overall brightness. This may offer you a great solution in a highly lit environment.

Hey, that sounds great! Well, yes, it used to be great, when projectors were quite underpowered and produced 250 to 400 ANSI lumens of light (10 to 15 years ago), but now the norm, even for cheap end projectors, is 1200 plus ANSI lumens and the requirement for high gain (redirected light) has all but disappeared in favour of unity gain (rated as near 1.0 gain). What high gain does is redirect the light towards a narrower viewing area, thus increasing brightness for viewers sitting in that area, but decreasing it for viewers either side. Because Screen Technics is a manufacturer - not an importer - we can accommodate these custom requirements.Īvailable leader for each screen is noted on this website, if you have any questions about the amount of leader you can purchase for a particular screen please contact the sales office.Įveryone thinks that high gain makes your projection screen brighter - not true.It cannot be ordered after the fact - you need to consider it at the time of purchase.The more leader you have the worse your Lay-Flat becomes on the screen, so seek advice as to what is acceptable before technical problems arise. Say you have a high ceiling and the standard leader length, which alters from product to product, still leaves the image area too high to be viewed with comfort, what do you do? - Order your screen with extra leader! Leader or Top Black Border is the amount of masked (painted black) material that resides above the white picture area on most roll down projection screens.Īll quality projection screens in Video 4:3, HDVT 16:9, 16:10 and 2.35:1 format will have leader above the image area, as this lets you lower the image area down into the room to achieve a comfortable viewing position.
