See-through wire mesh to ESD/RFI protect LCD?

Hi Joerg,

while i dont know about wire mesh, i do know something that might also help and would be worth a try: RS 264-9382 is supposed to be fairly conductive and more or less transparent. Its very expensive though, probably okay for low volume things but certainly not something you might want to use on cheap, high volume devices...

Thanks, Robert. Had cancelled right away because it should have gone into sci.electronics.design instead but I guess cancels don't work well anymore.

The price would be ok, we have to save an existing (large) base of units. But this film probably can't be glued on easily from the back.

Id glue it on with a strip of doule-sided film and then use aluminium or copper tape with conductive glue to get a electrical contact between the conductive side of the film and the front panel.

Ive seen similar construction on a display unit (probably from a old cash machine) i found at some trash yard.

That's a good idea. As long as this stuff survives "baking" in hot climates without falling off and into the circuit ... bzzzt. These units will sit in the hot sun all day long.

That would be hard to install in a reliable fashion. And the guys in Brussels would be pelting us ;-)

Lead glass window?

Something like this?

Wow, somebody was really determined there. But, quote "Finally, it starts to smoke." ... We can't quite do that here because there is a poly surface on the whole thing.

Not that stuff, but this version would work:

Thanks, Anthony!

Soll das jetzt ein Besipiel dafür sein, warum X/Multi-posts blöd sind?

Nein, ich hatte versehentlich den Knopf gedrueckt, bevor beide Adressen auf den korrekten englischsprachigen Gruppen standen. Gleich geloescht und neuen Post gesetzt, war aber zu spaet. Bitte instaendig um Vergebung.

Mit einem f'up wäre das nicht passiert. Naja, uninteressant ist es ja nicht ;-)

Joerg- google on "ITO film". Not a mesh.

It'll might a challenge to mount that onto the back of a steel panel though. Probably comes with an adhesive but that can stick to the existing polycarbonate that's already there if someone presses it hard enough.

Anthony's hint produced this:

Now I just have to get a sample, find some really good conductive epoxy that will hold up in tropical climates and we'd be home.

Bloss kein rotes :-)
