This work is done in collaboration with JVC USA.
While computer chips and networks have increased
exponentially in performance, displays have remained
stuck to the 1 million pixels (1 Mpixels) barrier
In collaboration with JVC, we built a
4 mega pixels high resolution desktop display at UC San Diego and
at the University of Sydney.
Although the idea of tiling displays is not new, we solved
the problem of uniform illumaination and colors across the tiled
Variations can be due to the light sources, the optical components
(filters, mirrors, ...) or the chip inside each projector. As a result, the image
produced is not uniform: variations of colors and/or intensity
We solved the problem by using a common light source for the projectors.
The white light is created by a Xe arc lamp, passes through a set
of red, green , blue dichroic filters. A bundle of optical fibers
guide the red, green , blue light to each projector D-ILA chips.
Desktop size was achieved by the use of short throw lens
fitted on each projector. The image created by one projector
is 21 inch diagonal. The total image area for a 3 x 1 display is
50.4 inches by 12.6 inches.
The Sydney display is driven by a PC cluster with graphics cards; the
UCSD display by a three Infinite Reality 2 SGI Onyx2.
The UCSD display was extended from a 1 x 3 display
to a 3 x 3 display by Steve Reinsch (JVC) during 2001.
Research in Sydney is proceeding independently from UCSD. It
will focus on improving the optics of the display and on a thorough
characterisation of the display.
The display is currently available to researchers and students.
