21. In 2009, Brookings, South Dakota-based Daktronics installed light emitting diode ( LED ) displays at the stadium. 22. He owns intellectual property in the area of material processing and die architecture of light emitting diodes . 23. In modern sense, OWC uses either laser s or light emitting diodes ( LEDs ) as transmitters. 24. The LED display module has an array of light emitting diodes mounted thereon, and a longitudinal axis. 25. Recent developments in semiconductor technology allows for the development of UV-C Light Emitting Diodes ( LEDs ). 26. The reverse process to photoinduced electron transfer is displayed by light emitting diodes ( LED ) and chemiluminescence. 27. Neutral doping ( i-type ) is required to produce devices such as light emitting diodes ( LEDs ). 28. This voltage ranges from 0.3 V for germanium diodes up to about 3 volts for certain light emitting diodes . 29. The screen displays 1 million LEDs ( light emitting diodes ), or high-tech light bulbs, and 150, 000 pixels. 30. Another chemist stole information from DuPont on Organic Light Emitting Diodes or OLED technology used for display and lighting applications.
