At the CEATEC show currently ongoing in Japan, Mitsubishi Electric showed off a 155-inch prototype OLED TV that is modular and can be upsized at will. It is composed of 720 OLED blocks, each sized at 1.5 square inches, but can be made bigger or smaller as necessary. This could be used in outdoor displays, like in ballpark stadiums and on buildings for advertising.

The modular nature also means the large screens can be curved in large installations, to follow the curvature of a building, wall or wherever else it's installed. Thanks to the OLED technology used in the creation of this system, brightness is said to be three times greater than in regular LCD TVs. Organic compounds in the pixels degrade over time, however, with the set's life rated at 20,000 hours of continuous use.

Mitsubishi has not released pricing nor a shipping date for the modular OLED technology.
