It can be applied to most projection configurations:
o Simple single-level arrays
o Complex multi-level arrays
o Domes and partial domes
o Front & rear projection
o Collimated displays
There is a slight blurring effect within the blend regions.
GBvi’s blending algorithms have been specifically developed to minimise this effect while still providing high-quality blends.
By way of example, we would allow 5 working days to install and set up a 13-channel Chronos blend solution although it has typically taken 2-3 days when working closely with the integrator.
The alignment processes significantly ease the installation and setup efforts, so even higher channel counts can certainly be supported.
However, if you would like help with display layout or performance analysis, we would be happy to offer this service.
We recommend the use of Chronos Mechanics, since this serves as a carefully designed solution optimised to fit with Chronos blend masks.
Chronos Mechanics are available in two forms: static, and actuated:
Static: fully adjustable by hand, and once it set up, is left permanently. Requires no further action!
Actuated: motorised (moveable) mask to remove the blend from the light path. A solution optimised for systems which show both light and dark scenes for prolonged periods.
This results in high-performance blending, superior to any plain-edge or sawtooth mask solutions that are also used – and it can withstand high light flux without degradation.
We can provide a proposal upon request.
However, with advanced notice and with quick provision of customer design data we can often turn systems around significantly faster.
GBvi does not offer complete display system solutions and integration; our normal mode of operation is to work with integrators and to develop good working relationships with them.
However, for darker scenes, the overlap region will quickly become visible as the leakage light from adjacent channels sums together.
While this could be compensated with ‘infill’, where a deliberate grey scale value is added to video signals to try to match this overlap, this significantly degrades the overall system dynamic range, making dark scenes appear washed out and lacking ‘blackness’.
Quality optical blending can completely eliminate this issue, so that dynamic range is optimised and transitions between ‘day’ and ‘night’ scenes do not need to be carefully managed.
