Mitsubishi Electric has confirmed that it will show a 149" prototype OLED screen at ISE 2010. Believed to be the world's first scalable OLED screen technology, the new system aroused considerable world-wide interest when it was revealed at last October's CEATEC show in Tokyo. A world-leader in outdoor LED screen technology with its Diamond Vision screens, the company believes OLED has the potential to similarly revolutionise its indoor commercial displays business.
