Display Backlighting


Nanosys is changing the way we see things. Our quantum dot technology creates a visual experience that is truer to reality by enabling LCDs to display 3 times more color than they can today. This means richer, more viscerally alive reds, a deeper palette of greens (the color the human eye sees more intensely than any other color) and vivid blues. Browsing through photos on a tablet is now more like holding a stack of high quality, professional prints. Watching a movie on a big screen in the living room is more akin to attending a private screening at a Hollywood studio.



How does it work?

QDEF™ (Quantum Dot Enhancement Film) is composed of Nanosys’ proprietary, high efficiency quantum dot phosphors. Larger than a water molecule, but smaller than a virus, these tiny phosphors convert blue light from a standard GaN LED into different wavelengths based upon their size. Larger dots emit longer wavelengths (red), while smaller dots emit shorter wavelengths (green). Blending together a mix of dot colors allows Nanosys to engineer a new spectrum of light. This allows LCD manufacturers to accurately match their LED backlight to their LCD color filters to achieve the best possible color and efficiency performance. The result is professional photo and cinema level color performance in the palm of your hand or on your living room wall.

While other advanced display technologies promise good color, most lack sufficient brightness to be used outdoors and are not scalable to high volume or large panel sizes. Smartphone, tablet, notebook computer and television manufacturers can turn to QDEF™ based displays instead – yielding eye-catching products, available today using existing LCD panel manufacturing infrastructure.

Process-ready components like QDEF™ integrate easily and affordably on a mass scale with existing LCD BLU manufacturing processes. Nanosys has formed definitive commercial agreements with cutting edge electronics component manufacturers including LG Innotek (LGIT) and Samsung for the first commercial application of quantum dots in consumer electronics. With the need for brighter, cheaper, better LED displays in everything from HD televisions to tablet PCs, Nanosys materials are unlocking the barriers to an enhanced color experience.

What’s the difference?

QDEF™ The QDEF™ is an optical film component for LED-driven LCD backlight units that can be scaled to any size, from tablets to large format televisions. Designed to replace the functionality of a diffuser sheet while actively converting color, QDEF™ can simply be added to the stack with little change in overall thickness or manufacturing process.
