LCD Projections
Projection displays look to hang in new niches
By David Lieberman, EE Times
New York -- Today's biggest market for LCD-based electronic projectors
is corporate presentations, but tomorrow's market will be really big: the
rear-projection TV. Until that tomorrow arrives, a number of applications
are emerging in which LCD projectors will carve out a niche.
According to one startup specializing in LCD rear projectors, Clarity Visual
Systems Inc. (Wilsonville, Ore.), the opportunities for rear projectors in
"dynamic signage" cut across entertainment, business and retail-market
applications.
Clarity and others have visions of big displays going into many different
venues. With diagonals of 40 or 50 inches, and sometimes "tiled" together
to form even bigger displays, projection display "cubes" will be installed
in department stores, according to big-display boosters, to present images
of models showing off the latest fashions; at kiosks in airports to pace
us visually through the room selection at nearby hotels, and at neighborhood
theaters to dish up short clips of the movies currently playing. One of the
first installations of a video wall of tiled Clarity displays, though, is
not in such leading-edge applications, but in a market segment that's been
an early adopter of advanced displays, both on desktops and on trading-room
walls: the financial community.
Clarity concluded an OEM agreement in the spring with video wall specialist
Imtech Corp. (Denville, N.J.), whose previous installations--nearly 1,000
of them--have used CRT-based rear projectors from Pioneer and Sony. These
include what Imtech claims is "the world's most sophisticated digital financial
information display," the 100-CRT, 55-foot-long, 11-foot-high display system
at the Nasdaq stock market. Imtech will be using Clarity's 40-inch VideoBanner
and 52-inch VideoWall LCD projection displays in future installations, starting
with a matrix of 52-inchers (four across, two high) on the Global Foreign
Exchange trading floor at Credit Suisse First Boston (New York).
But why use projection cubes based on LCDs instead of conventional projection
CRTs? "Frankly, for the form factor," he said.
Clarity's cubes "range in depth from 18 to 28 inches," said Paul Noble, founder
and chief executive of Imtech, "and so require only half the floor space
of other cubes. Many businesses have considered the addition of a video wall
in conference rooms, trading rooms or lobbies, but have decided against it
because of a lack of floor
space." (Next article.)
