QDX quantum dots do not degrade under the high temperatures used to apply film, silicon and polymer and allow for creative LCD display and LED lighting engineering as well as lowering protective barrier film costs.

Quantum Materials has already begun QDX quantum dot production using the company’s patented continuous-flow production system and assessment quantities have begun being shipped to the company’s largest potential customers.

"Our QDX Quantum Dots represent a game-changing development in advancing next generation display and lighting applications," claimed Quantum Materials Corp CEO Stephen Squires. "Their stability under high heat allows for more effective high temperature dispersion onto LCD display thin-film. In Solid-State Lighting, QDX Quantum Dots used in QD-LEDs will give better performance and effective life in high-heat and moisture-laden environments without degradation. We are excited to see QDX Quantum Dots unleash the engineering and design teams of our customers to facilitate advances in display and lighting applications never before possible."

QDX quantum dots have been tested to withstand heat resistance to 150 degrees centigrade for four hours with no oxidation performance degradation in an open air environment. Quantum Materials believes that QDX attributes and availability in commercial quantities will lead to large-scale mass-production of QD-LCD displays in the near future.

For Quantum Dot Liquid Crystal Display (QDLCD) manufacturing, QDX quantum dots reduce the need for expensive barrier films currently needed to prevent quantum dot degradation from moisture and oxygen. Custom characteristics can also be incorporated into QDX, including large Stokes shift to reduce re-absorption loss for increased luminescence and better color purity.

QDX Quantum Dots are ideal for LED lighting development because they claim to be more stable than organic phosphors and their high heat resistance enables better LED manufacturing capability, high illumination performance, long lifetime and resistance to power spike damage. Solid-state lighting made with QDX LED’s will require fewer heat sinks or baffles and bring new and simpler design form factors to the lighting.
