Kyoto-based company Rohm impressed us at last year's CEATEC with a mega-tiny OLED display but it didn't rest on its laurels. A larger prototype exhibited this year emitted ambient light at 3,000 to 4,000cd/m² and a brief flash at 100,000cd/m² -- that's respectively 10 and 250 times the brightness of a typical LCD display. But the impressive bit was this: nothing illuminated cast a shadow. Obviously a light like that is a poor match for a haunted house or romantic restaurant, but surgeons use shadowless lamps at the operating table, so there are applications. The short shelf life of OLED materials is still a nagging disadvantage, but as Dr. Eldon Tyrell would say: "the light that burns twice as bright burns half as long, and you have burned so very, very brightly." Then again, he was talking about cybernetic killing machines, so, maybe not such a great endorsement.
