The venerable incandescent lamp is under assault–rightly or wrongly–as an inefficient blight on our environment (note: we're not discussing the validity of that argument here). Some incandescent ...

Coming soon to a television near you: next generation, quantum dot light-emitting diodes (QD-LEDs) that will illuminate displays without using cadmium, a toxic metal. Researchers led by Eunjoo Jang of ...

Researchers at Linköping University, Sweden, have developed a digital display screen where the LEDs themselves react to touch, light, fingerprints and the user’s pulse, among other things. Their ...
