Head to your nearest mall and you're sure to see some sort of video wall that is made up of smaller screens showing a portion of the overall picture. Samsung has shown off a 21.6-inch square display, which features a 1:1 aspect ratio and more importantly a 5.5mm bezel so that they can be stacked and installed next to each other to make up a bigger surface.

It's also reportedly much more efficient than slamming a TV onto your wall as they automatically adjust brightness and can save up to 30 percent in power. Along with this innovation, Samsung is unveiling the NL22B, which is a transparent screen in the shape of a case. This builds on the see-through tech presented at CES.

The idea here is that the case can show facts and figures while the merchandise is still visible behind. It would likely be used at that high class jeweler you like to shop so much. Imagine the screen enticing you to buy that $6,000 watch with its cool interactivity and other features.

Both will be shown at IFA, but don't expect them to be for sale, not just yet, anyway.
