PLEDs? Think Invisible Warriors - Think Predator!

Quite a while back I had this idea for creating a product that could be used to sell to our Department of Defense. I’m writing this article because I found out that such a technology is already in place, unfortunately for me. Let me introduce Polymer Light Emitting Diodes also known as PLEDs. A company by the name of Cambridge Display Technologies has been working on such a technology for years. PLEDs gives the ability to display images on thin-flexible material. Think of all the many uses this technology could give us. Remember that movie Minority Report with the moving video on the cereal box or newspaper? PLEDs could be just the technology that would allow for this.
My idea, a little different. Take this PLED technology and develop some type of body suit that is wrapped with it. On this body suit there could be hundreds if not thousands of small cameras and PLED displays. Imagine for every piece of PLED display there is a small camera that is assigned to it. So, in a basic example, imagine on the front of your body suit you would have PLED displays that correspond with unique cameras that are on the back of your suit. Each PLED panel would display the image that is captured by its assigned camera. Now imagine hundreds or thousands of these PLED displays and cameras working in conjunction at the same time - each showing an image from which the camera is directed. Ultimately, you can make an invisible object.
If you were looking at an object right in front of you that is really a display showing an object behind it (captured by the cameras) you wouldn’t be able to distinguish the object in the middle because you are seeing what’s behind it. See my example, below:
Take this example above and picture it with a person as the object in the middle. This person would be in a body suit with PLED displays and cameras. If you were to look at this person, you wouldn’t see him - you would only see his surroundings or whatever images the cameras pick up. Ultimately, I don’t think it would every be perfect whereas the object would be completely invisible, but I do think you could get it close enough so that it would more so resemble the creature in the movie, Predator - where he is not completely invisible because you can see a vague outline of his body. Imagine this technology applied to our Specials Ops and Armed Forces. We could have invisible stealth warriors.

[John Pendry, a physicist at the Imperial College London] and his co-authors propose using metamaterials because they can be tuned to bend electromagnetic radiation — radio waves and visible light, for example — in any direction.
A cloak made of those materials, with a structure designed down to the submicroscopic scale, would neither reflect light nor cast a shadow.
Instead, like a river streaming around a smooth boulder, light and all other forms of electromagnetic radiation would strike the cloak and simply flow around it, continuing on as if it never bumped up against an obstacle. That would give an onlooker the apparent ability to peer right through the cloak, with everything tucked inside concealed from view.
