Quantum Dot Enhancement Film For LCDs

Nanostart’s Nanosys launches new LCD technology for display manufacturers and promises all kinds of colors with nanotechnology. To create QDEF, Nanosys’ engineers suspended a blend of quantum dots within optical film and applied it to a blue LED, which helped get the nanocrystals excited and the dots emitted high-quality white light and a rich, wide color gamut, without consuming as much power as white LED-based materials………

 

Nanosys Inc., an advanced materials architect announced that its next generation LCD technology, the Quantum Dot Enhancement Film (QDEFTM), is available to display manufacturers. Device designers can now increase color gamut by as much as three times without making the trade offs in cost, size and brightness they’ve had to make in the past. This means richer, more viscerally vibrant reds and a deeper palette of greens the color the human eye sees more intensely than any other color. QDEFTM represents the first time that quantum dot technology is available to display makers in an optical film, which can be scaled to any size including large televisions. The current generation of displays in smartphones, tablets, laptops and large format TVs can only express 20 to 35 percent of the colors the human eye can see. QDEFTM displays will unleash a whole new level of content creation and revolutionize user experience by delivering over 60 percent of visible colors. “We believe color will be a significant differentiator for early adopters of quantum dot technology; and, QDEFTM will give display makers a competitive edge by providing consumers with a color quality experience they have only seen in movie theaters and professionally printed photos,” said Jason Hartlove, president and CEO of Nanosys. “Almost all content available today has to be dialed down to match the limited capabilities of current displays, but with a QDEFTM enabled display developers and producers can create a photo-quality color experience for the user.”

 

Designed to be process-ready, display makers can easily integrate QDEFTM into current manufacturing operations without retooling an existing line, as is the case with other technologies. This not only extends the life of their current capital expenditures, it allows for the reuse of equipment, reducing industrial waste. QDEFTM is engineered using Nanosys‘ patented quantum dot materials dispersed in a polymer matrix and suspended within an optical film. The advanced material creates an improved quality white light with an unprecedented range of hues when excited by an energy-efficient blue LED. This results in better color and less power consumption than when using white LEDs. Last year, Nanosys commercialized its quantum dot technology with the QuantumRail, a process-ready component for smaller format LCDs that improves color gamut and power efficiency. The company plans to expand its manufacturing capacity as it continues to commercialize its LCD and energy storage technologies.
