High-definition large-screen display from combination of nine projectors
|
----Who are your rivals in this field?
Most of the companies that manufacture projectors.
Of those, some companies are trying to achieve a high-quality picture
using just a single projector. The problem with just the one projector
is that a large-screen display inevitably becomes somewhat dark.
Getting that combination of brightness and high definition requires
a lot of expensive technology. Even if you can do it, the costs
shoot up. For the moment, therefore, the display can really only
be used by theaters.
Whichever way you look at it, the demand for
better picture quality is rising. There are essentially two approaches
being taken: the single-projector method, and our approach, which
is to create a large-screen display by stacking projectors in a
box configuration. Both approaches have their pros and cons. With
a single projector, it's quite easy to pick it up and move it around.
But the price you inevitably pay for that is a lack of brightness
and a much lower pixel count. If you try to get round this problem
by constructing a system made up of, say, 50-inch flat-screen television
sets, you have the new problem of a screen with joins and issues
over color consistency between the various screens.
The HDPS100 does not have any joins across
the screen, and yet it still produces a much better picture than
with HDTV. By combining nine relatively inexpensive projectors,
we've managed to create a screen with very high picture quality
overall. Although the projectors are constantly improving, this
type of system has an additional advantage in that we can vary
the type of projector used. So if certain customers have a different
image quality specification, it is possible to change the projectors
and bring down the total cost of the system.
----But aren't the projector suppliers also your competitors?
They are. But they are also our business partners--so
much so that we have a line-up of projectors being offered to us
that they would like to see incorporated into the product. We believe
this is a product with a unique positioning that does not compete
with their own ranges of products.
