Technology – 4 Fujifilm Z-5000 series projectors. Selected because of the non-offset projection, which allowed the projectors to be mounted close to the ceiling and maitain the image at a high level without having to keystone correct.
Projection vs LCD vs LED – Why projection? While the installation of an LED/ LCD wall would have been possible several fators speak against it. Space: The projection can be done right on to the wall. LED and LCD require mounts and add thickness. This would mean loosing between 10-20cm in room depth. As a result the seating would have to be moved away from the wall and reduce seating capacity. The close up to an LED/ LCD screen may further be unconfortable for the visitor.
Image brightness. The projection set-up provided a comfortable image brightness, which harmonized with the restaurant brightness. As a result the images were not intrusive and could be watched comfortably.
Ambient light effect. Of course the selection and positioning of the room light and any other ambient or intrusive light is critical to avoid interference with the projection.
Operation Temperature power consumption – The overall powerconsumption of the projection is low. On one hand the projectors consume only a small amount of energy and the limited heat generation does not require additional, costly, airconditioning.
Investment and maintenance – Compared to LED, the investment for such a set-up is significantly lower. With 20,000 hr light source life, long operation with minimum maintenance can be expected.
Image processing: The playback can be done using either a single Media Player with a Geobox for image plitting in loop mode or for player synchronized via LAN. The use of four player provide a fall-back in case a player fails. Three screens remain operational. Investment wise there is little difference between single player and image processor or a four player installation.
