Companies Partner for QLED Printable Platform

WATERTOWN, Mass., Nov. 12, 2010 — QD Vision Inc. and Solvay have signed an agreement under which they will develop a printable electroluminescent platform for quantum dot LEDs (QLEDs) that will lead to a new generation of solid state lighting products.

Developed by QD Vision, QLEDs are a reliable, energy efficient, tunable color solution for display and lighting applications. They reduce manufacturing costs, while employing ultra-thin, transparent or flexible materials.

QLEDs utilize printing technologies to enable the manufacture of electroluminescent lighting devices in a wide variety of form factors including thin, lightweight, and flexible substrates. These new solid state lighting devices can be produced efficiently in high volume and at low cost.

Quantum dots provide the stability and reliability of inorganic semiconductor materials, and can be processed in solution. This unique capability enables the efficient manufacture of next generation electroluminescent solid state light sources with extraordinary color quality, efficiency, and stability.

“Our strategic partnership with Solvay is the first step in creating an ecosystem of solutions required to commercialize the QLED materials that will lead to a new generation of energy-efficient, solid state lighting products,” said Jason Carlson, president and CEO of QD Vision.

QD Vision is a quantum dot product company that delivers highly differentiated lighting and display solutions. Its Quantum Light platform enables step-change advances in current generation solutions, such as LCDs, LEDs and even OLEDs, and ultimately a significant leap over these technologies. Leveraging a first-tier patent position in nanotechnology originating at MIT, QD Vision is a privately held company based in Watertown, Mass.

Glossary

electroluminescence: The nonthermal conversion of electrical energy into light in a liquid or solid substance. The photon emission resulting from electron-hole recombination in a PN junction is one example. This is the mechanism employed by the injection laser.
nano: An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
nanotechnology: The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
quantum dots: A quantum dot is a nanoscale semiconductor structure, typically composed of materials like cadmium selenide or indium arsenide, that exhibits unique quantum mechanical properties. These properties arise from the confinement of electrons within the dot, leading to discrete energy levels, or "quantization" of energy, similar to the behavior of individual atoms or molecules. Quantum dots have a size on the order of a few nanometers and can emit or absorb photons (light) with precise wavelengths,...
