Something tells us that whenever we do round two of our Time Square signage Engadget Show, Mitsubishi's modular OLED display will be amongst the highlights. Aimed at outdoor applications (but obviously ready for your living room), the scalable prototype shown here at CEATEC was 155-inches in size. The wild part, however, is that it could grow infinitely larger -- at least in theory. The whole panel that you notice from afar is crafted from smaller OLED blocks that snap together like a puzzle; the more you add, the larger your screen can be. Unfortunately, resolution is still relatively low and longevity is a definite concern, but if you can manage to stand a few feet back, the result is simply stunning. Hop on past the break for a new take on "immersive."
