The downside of course, is that each display is surrounded by a bezel, which creates a screen door effect on a massive scale.  But as televisions get more and more streamlined, multi-screen displays are looking a lot better.

Sharp's latest multi-screen has a total of 6.5mm between each set.  It's the smallest bezel ever, and it's done by making the individual televisions just a bit off.  The left and top sides of the PN-V601 hold most of the wiring and other components, resulting in a 4.1mm bezel.  The right and bottom sides only need a 2.4mm bezel.

The new displays will hit in Japan this August with a US release date yet to be announced.
