The thing I find amazing is not so much that they were able to use colour refracting to overlay invisible messages on bad LCDs... it's looking at the problem in "creative-reversedness" (yes I just made that up).
We all would look at the limited viewing angle as a problem. Not enough people can see the TV, colour is bad, blah blah. But if we were to look at the problem in reverse - Too many people can see the screen from all angles, colour acuracy is not that important for all applications, and so on... we actually define a product that we can fit in the banking, HR, etc roles.
The next feat of genius was looking at what was causing the original problem and then leveraging it to create the new fuctional solution. Many just use the polar lenses, now you can just create a app that overlays invisible ink.

Great job.
