3M and Nanosys team-up to roll out quantum dot-enhanced LCDs
Nanosys' eye-popping QDEF (Quantum Dot Enhancement Film) might be inching closer to a display near you. A new partnership with 3M aims to get the color-loving tech commercialized and into mainstream products. The film uses quantum dots to create an LCD with a wider color gamut -- apparently translating to up to 50 percent more color. The quantum dots are packed onto this film in their trillions (yes, trillions) which is then fitted within the backlight. As the new layer would replace the existing one within LCDs, Nanosys' solution aims to avoid the need for new equipment or processes. However, we're still waiting for high-color QDEF to become that "ecosystem changer" we were promised.
Nanosys QDEF screen technology ships in Q4, slips into iPad at SID 2011 (video)
We dropped by Nanosys' nook at SID 2011, and not only was it showing off its new Quantum Dot Enhancement Film, but had hacked the tech into an off-the-shelf iPad. A company representative presented the modified slate as an example of how quickly QDEF's high color gamut magic could be integrated into existing devices, offering "OLED color depth without OLED power consumption and OLED price." Sure enough, we were told to expect to see QDEF in a "mobile device," probably an Android tablet, sometime in Q4; when pushed for details, our rep could only tell us that the device would come from a Korean firm. (LG or Samsung, take your pick.) Integrating QDEF into new devices may be a snap, but company representatives told us the film could add as much as 100 microns to a screen's thickness, suggesting that smartphone manufactures aren't too keen on the idea of a thicker display. Still, Nanosys has high hopes for the new film and told us that it expects high-color QDEF to become an "ecosystem changer," as industry-altering as HDTV. The firm even suggested "wide color gamut" apps could be in our near future -- we love our color depth here at Engadget, but somehow it's hard to see Angry Birds: High Color (its suggestion, not ours) taking off.

Nanosys unveils Quantum Dot Enhancement Film for LCDs, promises all kinds of colors
Another day, another step closer to quantum dot reality. Today, Nanosys unveiled its new Quantum Dot Enhancement Film (QDEF), marking the first time that the nanotechnology is available for LCD manufacturers. According to the company, its optical film can deliver up to 60 percent of all colors visible to the human eye, compared with the 20 to 25 percent that most displays offer. 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. Once they started hopping around, the dots emitted high-quality white light and a rich, wide color gamut, without consuming as much power as white LED-based materials. No word yet on when we can expect to see QDEF in consumer displays, but Nanosys claims that the film is "process-ready" and easy for manufacturers to integrate. For now, you can amuse yourselves by comparing the two frogs pictured above and guessing which one is covered in quantum dots. Full PR after the break.
