Behold the 155-inch OLED TV

For a couple years now, 150 inches has been as big as a television can get.

So how did Mitsubishi one-up the record with a 155-inch TV -- using the notoriously expensive and generally quite tiny OLED technology, to boot?

The secret: They cheated.

Mitsubishi's enormous OLED television is actually built from hundreds of tiny OLED panels, each a minuscule 1.5 square inches in size. By putting the tiles together in a checkerboard pattern, the mega-TV is created.

This approach is common with other technologies where multiple panels are placed next to each other to create a larger set, but those typically have borders that leave seams in the image. The OLED TV has a much smoother appearance in comparison.

So it's not really a "new record" television, but it does have some advantages. The modules can be curved or wrapped around uneven surfaces, and thanks to the underlying OLED technology the set is incredibly bright: Three times as bright as an LCD TV, at least initially (as OLEDs degrade over time and become progressively less bright). The set is also not limited to 155 inches in size. Additional squares can be added to the mix as needed, so the television can get infinitely large.

Mitsubishi's set is just a prototype right now, but the underlying technology is fairly simple, so there's no real obstacle keeping it from becoming a commercial reality... except for what is probably a rather exorbitant cost.
