- Background
- The motivation for this project was to build a high resolution desktop
display which would
allow a viewer to look at a high resolution image (namely larger than
1280x1024). Such
images are created routinely by scientists but also in the world. For
instance the highest resolution on a standard Kodak Photo CD is called
16Base
(3072 x 2048) and cannot be displayed on a conventional monitor. A Kodak Pro Photo CD allows
for even
higher resolutions.
While computer chips and networks have increased
exponentially in performance, displays have remained stuck to the 1
million pixels (1 Mpixels) barrier (1280x1024).
This is primarely due to the limitations of CRT
technology which requires a bulky cathode ray tube for higher
resolutions.
With the advent of Liquid Crystal Displays
(LCD)
projectors and displays, and Digital Light
Processing (DLP) projectors, resolution is getting better however
technological problems remain. To this date high resolution at a
reasonable price is still achieved by CRT's.
- Related work
- One way to increase the resolution of a display is to
"tile" several projectors such as
done in Power Walls and project
the composite image
onto a screen.
- Several groups have worked on this type of
project:
- Paul
Woodward et al: Powerwall
- DeFanti
et al: Infinity Wall
- Pat
Hanrahan et al: Interactive Mural from the Stanford Interactive
Workspaces Project
- Kai
