A: QLED stands for “Quantum Dot Light-Emitting Diode”. It has quantum film and its light-emitting layer is made of quantum dots instead of
phosphor as in conventional LED.
A quantum dot is a nanocrystal made of semiconductor materials. When exposed to visible light or electric currents, it emits bright visible light of pure color spectrum. Quantum dots made of different materials emit different light. According to the range of fluorescence absorption, they can be divided into red-light-emitting, blue-light-emitting, and green-light-emitting quantum dots.
For QLED, blue light is used to excite quantum dots so that they emit red and green light; the efficiency of light emitting can be enhanced by 30-40%. QLED displays have such strengths as pure colors, great stability, less use of electricity, low cost, and wide application, but there are also
problems, including manufacturing process yet to mature, life cycle yet to be prolonged, and environmental impacts.
