LED takes the lead A
Holovis explains why LED is the future for Flying Theatre screens
t Holovis, we believe the future of Flying Theatre screens for attractions – and indeed, a lot of theme park AV displays – is in Direct-View LED (LED). Projection has ruled this space since the creation of these
attractions, and still has advantages of its own – but, for large-scale screens with these sort of viewing distances, LED should be a top consideration when designing these attractions. There are several reasons why we strongly believe in LED for Flying Theatres.
First, and most obviously, it allows us to have much higher brightness levels inside the theatre than we could previously have. This is both in the power of the diodes themselves but also in the optimization of brightness and contrast ratios. A Flying Theatre is often recreating the sensation of being outside, and LED technology provides a much higher brightness level, better contrast and a more balanced ratio between the two. A key challenge of domed screens is
levelling out the two factors given the cross-talk in bouncing light, which LED technology suppresses dramatically. The technology also allows us to keep the environmental light level high – you could even place one outside and still get a great viewing experience! LED also requires lower general maintenance than projectors for engineers
and technicians. When multiple projectors are blended to create a single large image, that large canvas needs to be maintained. Projector alignment, consistent brightness levels of all colours, uniform black levels in dark scenes and focus are some of the factors technicians have to worry about. Whilst not maintenance free, once LED is built, bedded in and working, there’s generally less worry if the spares inventory is kept appropriately stocked and is well considered during the design and initial procurement phases. Holovis still believe projection is vital in AV installations, and a blend of
technologies will generally continue to be the right choice, but for screen shapes like domes, cylinders and single radial curves, LED is the go-to for Holovis. Projection technology generally has a lower facility impact, a large projected screen surface is still required but it will generally be lighter and will require less PE engineering works, and appropriate power for projectors will be lower. Projection still has superb and superior colour reproduction for high-end applications, giving colours that LED technology cannot truly match just yet. For some clients this might make all the difference in certain applications. For others, the advantages of LED are much more appealing. Historically the big difference has been price – with LED traditionally coming
in at a much higher price point. We are continuingly seeing this price parity shift, and at Holovis, we are very excited to announce that through new technology developed alongside partners, we can provide hemispheric LED wall design and installations at very similar cost to projection. David Wolber, Engineer for Holovis, confirmed that “this means that Holovis can provide an LED screen for your Flying Theatre at a price parity with projection – overtime possibly even working out cheaper due to lower life-time costs”.
