Before LED lights were introduced, many auto companies used halogen bulbs to light up the road, typically producing 900 to 1,000 lumens of light. LED bulbs however produce from 3,600 to 4,500 ...

Since the technology is better, all LCD TVs now use LED lights and are colloquially considered ... QD-OLED TVs combine a quantum dot layer (just like a QLED) with OLED, to deliver richer colors ...

We have achieved high color purity luminescence through improvements to the material and light-emitting diode structure using quantum dots that do not include toxic elements such as cadmium or lead.

QLEDs, employing quantum dots, offer enhanced color performance and brightness, bridging the gap between LED and OLED technologies in terms of color saturation and energy efficiency. While LEDs are ...

One alternative, quantum-dot light-emitting electrochemical cells (QD-LECs), incorporates ... “We report another class of EL devices, which is called QD-electrolyte LED,” the researchers explain. “The ...
