Since
the evolution of Interactive Plasma Displays,
most manufacturers have discontinued the production
of Rear Projection Interactive Whiteboards.
Please look at our collection of Interactive
Plasma Displays if you need a high quality
display or if you do not want to use a projector
with your interactive whiteboard.

Plasma Displays
A plasma
screen is a large widescreen monitor, from 32"
to 84" in size, which has the advantage
of being very thin so that it can be hung on
walls. Plasma screens can be used with computers
and video recorders/DVD players etc. A plasma
screen overlay is a device that fits over a
plasma screen. Plasma screens that have an interactive
overlay on them work in exactly the same way
as interactive whiteboards. The advantage of
using a plasma screen is that a shadow is not
cast by the presenter, unlike front projection
interactive whiteboards.
What
am I missing ?
Rear
projection interactive whiteboards work similarly
to the front projection whiteboards. In rear
projection interactive whiteboards, the projector
is mounted behind the whiteboard and a series
of mirrors project the image on the screen.
The advantage of rear projection over front
projection is that the presenter does not have
to look into the projector light when speaking
to the audience and the presenter also does
not cast a shadow on the board. The disadvantage
is that these systems are usually 5 times more
expensive than front projection whiteboards.
They also take up more space, as the back is
bulkier due to housing the projector. Therefore,
for obvious reasons they are now obsolete. Please

for all the features and benefits of a rear
projection interactive whiteboard with high
picture quality at an affordable price.
