Targeting next-generation handheld devices with curved control and display surfaces, a flexible LED-based backlight is approximately 1 mm thick and can be bent with a 5-mm radius over 40 mm of display ...

Electroluminescent light emitting devices constitute an important class of optoelectronic components that directly convert electrical energy into light. These devices have evolved from early systems ...

With OLED-equipped TVs, monitors, and other gadgets slowly becoming more readily available at lower prices, attention is turning to what the next landmark consumer display tech will be. Quantum dots ...

Why it matters: Manufacturers have included quantum dots in LED displays for a while now, but they're working on screens that exclusively use them. The technology could become efficient and cheap ...

Proposed multijunction electroluminescent cooling system, consisting of multiple semiconductor layers with different band gaps (the energy needed to move an electron so it can conduct electricity).

Many of us have become disillusioned with screens in cars, and it’s little mystery why: they can be overwhelming, unsafe, and make simple tasks just plain annoying. They’ve also replaced the intricate ...

Lanthanide nanocrystals offer ultrahigh color purity and high stability, but their insulating nature has long blocked ...

(Nanowerk News) Electroluminescence is the phenomenon behind how LEDs work. It involves adding charge carriers, either electrons or holes, to a semiconductor. This changes the semiconductor’s ...
