BRIGHTER, flatter, less power-hungry display screens are on the way thanks to
a new breed of organic light-emitting diodes, researchers told a meeting of the
Materials Research Society in San Francisco last week.
For years, organic light-emitting materials have looked like a good bet for
making anything from flexible computer screens to colour displays for
cellphones. Screens based on these materials operate at low voltages, give good
colour contrast, and can be viewed from an oblique angle. However, they have
never been very efficient at converting electricity into light.
But now researchers have announced that they can make ultra-efficient organic…
