There are levels of complexity when it comes to invisibility, so I will start out simple and get more complex as I go along.
to start I will give the most simple way to invisiblize something. all you need is a camera and a new kind of screen called a PAPER LCD screen.
basically all you do is wrap your paper lcd screens around the bottom of an air craft and have a camera pointing upward into the sky and project the image of the sky onto the bottom of the craft, depending on how high you are off the ground the camera will have more or less zoom.
imagine for a moment how that concept would work, a similar invisibility device has been used on a car this video shows that car, it doesn't use paper lcds but it's basically the same concept.
holy crap right, Now that screen had terrible resolution and color. The paper lcds have hd capability, also that invisibility isn't as good as it looks, it's all about "forced perspective" if you weren't looking at the car STRAIGHT ON
then it wouldn't look invisible.
Full on invisibility, now imagine the paper lcds covering an entire vehicle like the car you saw but all the way around, on top of the car will sit what is known as a panoramic camera it will be able to make a image which can see everything around the car. The camera would be able to identify a target such as a human face and lock onto it, determine his or her distance from the car and line up what the person would be seeing behind the car then the image would be distorted to match the curves and angles of the car as to correctly match the line of sight of the target so no matter were you or the target moves the forced perspective remains in sync so that the car still appears to be invisible to that one person again it's all about forced perspective.
an invisibility cloak for a human. unlike a car, tank or plane, when a human moves his shape changes, so if you were to have an invisibility cloak and you were running around with it then the screens would flap around and greatly bend and move into different shapes. you must compensate for this by using a computer program which can tell what shape the cloak is in, in real time. picture a cloak in a video game, inorder for the cloak to look realistic it must flap around, through the use of a technology similar to motion capture you can make the clock move realistically. then the distortion would flex and bend correctly as the person moves, but other then that the concept remains the same, little electrodes on the inside of the cloak would be connected to a computer to create a cgi, digital cloak that moves as the real cloak moves using this you can accurately distort the image as the cloak bends and moves around.
panoramic camera mounted on the head which can lock onto a human face, determine the target's distance, line up and properly zoom the image behind you and project it onto the front of you and distort the image to match the bends and curves of your body.
It's all about forced perspective, you will appear invisivible to the person your locked onto but if someone was not locked, say someone on the side of you, he would see a strange distorted image. one at a time only
but still, it could prove quite awesome still, it is a type of invisible I guess.
If you or your vehicle are completely covered in lcd screens then how would you see out of the dang thing?
the answer is augmented reality, you guys have heard of that new "ocular" virtual reality goggles right, well instead of playing video games with those you can hook it up to the panoramic camera, you can see pretty much see right through your car. you could also put in heads up display information while you wear the goggles, even a translucent cgi frame of your car so you know exactly were the car is. Im talking epic ass future cop shiz, this thing would be so high tech it's ridiculous, no actually it would be freaking redonkulous.

One may get some benefit from the LCD screen, but the view changes based on where the observer is. So, if you look at a chair in the middle of your room. The chair will obscure different parts of the room depending on where you are observing it from.
Gross changes such as a 90° angle, and you could take a photo of a different point in a room. However, even what is obscured is determined by how tall you are, whether you are sitting, or how close you are to it.
Now, an airplane viewed from the ground might do well with a flat blue paint, or perhaps a fairly simple color scheme that will adjust to blue sky vs clouds, and adjust the contrast and brightness a bit.
A truck driving along the ground would have a lot of troubles maintaining invisibility for multiple observers. Now, if there is just one guard or guard station one is concerned with, it might work, as one could optimize the view for the single guard.
You might look up virtual windows that actually track the observer, and change the scene based on the movement of the observer.

CliffordK you got the right Idea, like I said one at a time only. :-'( It's got it's short comings but it's only the first one, I think it would work, the technology already exists (barely) But all in all do you think it's possible?
I see it used on jet fighters, in dog fights, in that type of scenario there would only be a few targets to lock onto, and it would make it really, really hard for the enemy to keep up with you because he can't see you an actual "stealth" fighter. you have to admit though, it would be bad ass, am I wrong?
