Displays grow big, thin and organic

摘要

The Panasonic half-ton, £50,000, 150in plasma screen, pictured on page 11, got a lot of attention at CES, but more important was the emergence of large, organic light-emitting diode (OLED) screens.These use polymer semiconductors instead of the usual silicon and are inherently brighter and more efficient, but have previously been available only in small sizes for camera and phone displays.
