Scientific Image - Organic Light-Emitting Diode

This is a photograph of an organic light-emitting diode (OLED). OLEDs are being used in the newest generation of television screens. An OLED is comprised of a thin organic film held between conductors. When electrical current is applied to the conductors, the film emits a bright light. Because OLEDs emit light, OLED-based displays do not require backlighting. That's why these displays are both thinner and more efficient than today’s common LCD screens, which require an additional internal light source.

Organic Light-Emitting Diodes (OLEDs): Cart Version

In this cart demo, visitors learn about organic light-emitting diodes (OLEDs). Prior to presenting this demo, an OLED should be made in a chemistry lab. This OLED is shown to visitors during the cart demo. During the demo, visitors learn how OLEDs work and what devices currently use OLEDs. Additionally, this activity includes a demonstration of spin coating, which is a process used to make OLEDs.
