View Resource How an OLED Works

From the website How Stuff Works, this is a collection of visuals on the manufacture, performance, and function of OLEDs, which are new high definition televisions using a technology called organic light-emitting diodes.

View Resource Light Emitting Diode (LED) Simulation

This interactive website from the State University of New York at Buffalo provides a Light Emitting Diode (LED) Simulation. Users may select different factors and view the resulting outputs.

View Resource Working with LEDs: Estimating Semiconductor Band Gap Using LEDs

The Materials Science and Technology Teacher's Workshop (MAST) provides this activity for classes learning about semiconductors and LEDs (light-emitting diodes). The class will observe visible LEDs in simple electrical circuits, relate the composition of semiconductor materials with their behavior and estimate the band gap of a semiconductor material. The lesson includes step by step...

View Resource Light Up with Technology: LED Circuit Application: Middle School Lesson Plan

This activity from the Florida Advanced Technological Education (FLATE) Center asks students to "engineer and manufacture a light-emitting diodeĀ (LED) using a simple circuit." The class reviews electrical circuit concepts before studying circuit diagrams and then building a circuit in groups. Finally, groups compare their experiences and results and report on their findings, including ...

View Resource LED and Transmitter Characteristics

In this video from the ICT Center, learn about fiber optic transmitters. Explore the components of a fiber optic transmitter, including a source, a modulator, an electrical driving circuit, and fiber coupling mechanics. Animations illustrate how the process of spontaneous emission converts electrical information to an optical signal in a light-emitting diode, or LED. In addition, learn about...
