LED made from carbon-based molecules, not semiconductors.

A light emitting device similar to a LED, but where the semiconductors were replaced by one or a stacked layer of organic thin films. The organic molecules emit light when a current is applied. Unlike the leds the OLED technology provides the possibility for the production of high resolution displays. Displays based on oleds are supposed to be faster, lighter, brighter and cheaper than the common LCD displays.

Is 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 â€" size. The carbon-based molecules are much smaller. And according to a paper written by dr. Uwe hoffmann, dr. Jutta trube and andreas kl?ppel, entitled oled - a bright new idea for flat panel displays "oled is brighter, thinner, lighter, and faster than the normal liquid crystal (lcd) display in use today. They also need less power to run, offer higher contrast, look just as bright from all viewing angles and are - potentially - a lot cheaper to produce than lcd screens." see also lcd and led.
