Nearly here


If made more flexible, this display screen technology can provide wearable active camouflage.

Everyone is so worried about cameras or whatever device being visible from the outside of the camouflage, but I don't see how that would matter. If I suspended a 1/2" diameter camera lens 15 feet from you, while you were walking, would you even notice it? We have trouble finding our keys on a table in front of us sometimes, why would a tiny visible part of the camouflage matter? It is a whole lot better than simply wearing black clothes and walking slowly.

@TheAlchemistPirate - I was thinking the same thing.

Covering airplanes with OLED displays that match the background will make them essentially invisible until they're close enough for it not to matter. As long as you can't see it like 1000 feet away, it will be just fine for combat use.

The thing is, most guided rockets and early detection systems use thermal and radar signatures to track targets. Making a radar-absorbing, environmentally isothermic and isoluminous OLED display will be challenging. It's kind of moot since no respectable nation these days tracks air targets by sight.

Ground vehicles could benefit from this to hide them from air attack. As long as the plane has to be within about 1000 feet to detect a vehicle with the naked eye, the vehicles will be essentially invisible. (Maybe have some air jets to wipe out tire tracks or something, and some way to hide a dust trail)

However, the problem with thermal and radar detection remains.

I can see this put to good use in helicopters which need to operate in areas where there is an abundance of risk from small arms and RPGs, all of which are visually aimed. Otherwise, it is better to worry about radar concealment and make it go fast enough or high enough for visual target acquisition to be ineffective.

There is a glass that you can see through from one side and on the other you can words or a picture, its used a fair bit like an autoque for people talking. Also there is a bank with it on the doors, you see the bank logo on the way in but when inside you can see straight through the glass, its not mirrored or anything.

Yeah. It's a one way mirror.

I made one in a bottle instead of Silvering it properly !

So called "one way mirrors" actually aren't, they just exploit an illusion to appear that way. The trick is that you get a weak mirror that allows a lot of light to pass through. Then (imagining the standard police setting), you set up the lighting so that the interrogation room is brightly lit, and the observation room is dimly lit. From the perspective of someone in the interrogation room, there will be a very small amount of light passing through the mirror, which will be drowned out by the large amount of light being reflected by it, so as such they will not be able to see into the room beyond. From the perspective of someone in the observation room, the opposite will be the case - the small amount of light reflected by the mirror will be drowned out by the large amount passing through it, so they will be able to see into the next room, but they won't be able to see their reflection in the mirror.



Never accept that which can be changed.

If the glass has a polarized transmission filter allowing light to pass from the room being watched but the light in the watching room has opposite polarity , nothing can pass into the room being watched.

This isnt a mirror, its completely clear, they can them somehow show a frosted type text. I will try and dig around to find what I am on about.
Its way more like a clear LCD screen but not exactly the same, god this is frustrating trying to find something you dont know the name of!
