Hi.
A friend is looking, as part of an art project, to set up a large
number of mini LCD screens, ideally about the size of those found on
consumer videocameras (3 inch or so). these would i believe be fed by
a video source and form a sort of multi-mini-video wall.

I am trying to investigate the feasibility of this and if so, how
best to realise it from a technical standpoint.

Assuming one could get hold of said 3 inch screens (as camera spare
parts - As far as i know, screens this small are not commercially
available as are, say, those found in in-car dvd players and GPS
systems, which seem to be about 6 or 7 inches in size), I am assuming
they would need a few things added to be able to function without a
camera. Do most designs (panasonics etc) have the backlight , inverter
and driver chips as part of the fold out panel unit and would require
the addition of a power supply and video processing circuitry?

My initial reaction to this is that it would either be too hard to
obtain the screens in the first place and even if not so, would
require painstaking work to be able to get them running independently
of the camera for which they were designed. Plan B would be to source
small screens already premade, as consumer independent units - any
suggestions? maybe GPS/portrable dvd/modified video-surveillance set
(as in: http://www.fermax.com/frames.asp?idm...2&n2=52&n3=241 )

any thoughts welcomed.

Seems these would eliminate the any need for external circuitry. No
pricing info available on the sight though. But it gives you an idea of
what else is out there.
