Og den består af et lag en film og blå LED lys. Det skulle give bedre farver fra en LCD skærm.

Det ser nu ikke ud til at være en ny LCD teknologi, men derimod en ny type baggrundsbelysning (backlight).

Typisk anvendes i dag CCFL eller W-LED backlights. W-LED backlights er lidt mere strømbesparende ift. CCFL backlights, men giver til gengæld ikke så stort farverum.

QDEF ser ud til at kunne ændre dette, og åbenbart ved lavere strømforbrug ift. W-LED.

Ganske spændende i øvrigt.

Det er faktisk ikke en type backlight, men i stedet en optisk film. Den forklares således:

"Nanosys makes QDEF technology with its patented quantum dot materials. It disperses them in a polymer matrix and suspends them within an opitcal film. The material makes it easier to create a high-quality white light with a wide range of hues when hit with an energy efficient blue light-emitting diode.

Larger than a water molecule, but smaller than a virus, the tiny phosphors in the Nanosys quantum dots can convert blue light from a standard gallium nitride 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. Nanosys basically adds a new layer of material to an LCD screen during manufacturing.

This allows LCD manufacturers to accurately match their LED backlight to their LCD color filters to achieve the best possible color and efficiency performance.

Nanosys first commercialized the quantum dot technology with QuantumRail, a component that improved the quality of small-size LCDs. That technology has been licensed to LG Innotek."

Dvs. at i stedet for de typiske pseudo-white LEDs i LED backlights, der jo er blå LEDs overtrukket med gul fosfor, så dropper man fosforet og smider sådan et QDEF panel ind i stedet?

Alt andet lige er det vel også snarere til en ny type backlight, eller i al fald en anden måde at lave LED backlights på.

Synes faktisk det kunne være en forsidehistorie værd...
