Real life connects with sci fi - Transparent screens

Have you seen the transparent screens in Minority Report or Avatar.

Samsung and others are working on that technology now. So far the tech giant have been able to make their screen 40% transparent.

As you can imagine there will be a lot of future for this sort of technology if they can make it 100% transparent. You could imagine it in cars, your home, electrical devices and lots more.

There are going to happen so many things the 25 years on the tech front that we will not believe it.

That's unbelievably cool, but what on earth would the practical application for that sort of thing be? I could see maybe commercial applications for it (in store advertising), but other than that...

It does look interesting, but not very practical
