LG and the United States QD Vision today announced they will jointly develop quantum dot-based LED (QLED) nano-technology active matrix display.
Compared to the current screen, the new display screen to enhance brightness and brightness while reducing power consumption. QD Vision will provide a quantum dot technology, LG is responsible for the actual products.
Because the production process more streamlined, QLED screen manufacturers can further reduce the production cost, and the quantum dots of inorganic semiconductor materials can achieve the same with the stability and reliability.
QD Vision said that under the same quality, QLED expected to reach the energy saving OLED screen, twice the rate of increase while the light-emitting 30-40%.

Generally speaking, quantum dots by zinc, cadmium, selenium and sulfur combination. 1983 Bell Labs scientists have for the first time the U.S. was carried out research, but "forgot" to give it a name, a few years Houye Lu University physicist Mark Reed will be officially named this as the semiconductor micro-block " quantum dots, "and still in use.
Quantum dot has an unusual feature: When stimulated by light or electricity, quantum dots will be issued colored light, the color of the light from the quantum dot size and shape the composition of material and decided that the features that make quantum dots can change the source emitted light color.
MIT graduates in 2005 to create QD Vision. Sullivan, co-founder Cole introduced his company has completely mastered the quantum dots of light and color control technology, from the working principle that the quantum dots with YAG phosphor is similar to quantum dots by light stimulation of several types of divergence color combinations, and ultimately to LED lights emit white light.
It should be noted that quantum dots can be issued by the blue LED light source into a completely white, rather than the YAG phosphor can absorb only a part of that, which means that the same lamp brightness, the required quantum dots of blue LED lights less light in the electro-optical conversion of the natural need less power, more efficient performance make it superior in terms of energy saving.
