not made of semiconductors. It's made from carbon-based molecules.
That is the key science
factor that leads to potentially eliminating leds' biggest drawback �"
size. The carbon-based
molecules are much smaller. And according to a

entitled oled - a bright new idea for flat panel displays "oled is
