SINGAPORE: Computer users may soon be able to work on screens with displays

that give the appearance of being three-dimensional. The DVI actualdepth

monitors, developed by a private New Zealand-based research company Deep Video

Imaging, displays images on two physical planes to create a depth of field.

"People have tried like crazy to get the illusion of depth and the

closest you can have is wearing (3-D) goggles and standing at a particular

position," DVI director Lim Soon Hock said on the sidelines of a news

conference to launch the product. The monitor, which uses multiple layers of

liquid crystal display (LCD) screens to create depth, allows users to work

across what appears to be a foreground and background seamlessly, without the

need for 3-D glasses or specialized software.

"We have not come across anything which comes close to a DVI

monitor," Fong Yew Chan, an engineer and business development director for

the Singapore government-funded Institute of High Performance Computing told

Reuters. The institute, focused on high-end simulation research, is

collaborating with DVI on applications for the monitor.

"There are technological challenges to be overcome before you can have

this kind of display (which) not even the LCD manufacturers could overcome so

easily," Fong said. A rainbow effect called moire interference, which

occurs when two LCD screens are placed one behind the other, was one problem.

The "window box" effect where the side portion between the two

planes can been seen had to be eliminated, along with the reflection of the

screens off each other, DVI executive chairman David Hancock said. The monitors,

which are thinner than conventional cathode ray tube displays, are compatible

with all operating systems.

DVI has filed for several worldwide patents and spent about US$3.5 million in

research and development. The company, funded by New Zealand and Singapore

capital, will not manufacture the monitors itself, but hopes to license the

technology to others. The company plans to make prototypes for desktop computers

by next year. The monitors are currently available as manufacturing modules in

different screen sizes.
