TV displays in 2015 will constitute 52 percent of the wide-color-gamut market as measured by total display space, the company said. That percentage is forecast to rise to 86 percent in 2020.Read More
The International Telecommunications Union’s (ITU) Rec. 2020 standard for wide color gamut, which has been set as a target for next-generation 4K Ultra HDTV displays and is included in the recently published Ultra HD Blu-ray specification, may be achievable more quickly than many industry experts thought.
That was the assessment of quantum dot technology specialists from 3M’s Display Materials and Systems Division attending last week’s SID Display Week show. The company intended its statements and demonstrations at the show to contribute to a discussion on how to set guidelines for displays to qualify as Rec. 2020 complaint.Read More
With Quantum Dot Enhancement Film, LCD makers now have an efficient mechanism for integrating quantum dots into their manufacturing processes.
After decades of research and development, the first liquid-crystal displays containing quantum dots (QDs)—molecule-sized spheres of semiconductor materials—are coming to market. These displays will have the ability to express as much as 50% more color than earlier LCDs, resulting in color performance approximately equal to or exceeding that offered by commercialized organic light-emitting diode (OLED) displays.
LCD makers are exploring several technologies for integrating QDs into their manufacturing processes. 3M's Quantum Dot Enhancement Film (3M QDEF) is proving to be an efficient and durable mechanism.Read More
Quantum Dots provide an amazing super high technology performance enhancement for LCDs through a unique application of Quantum Physics. By incorporating them within the Backlight the LCDs then produce highly saturated primary colors that are similar to those produced by OLED displays, plus they also improve the brightness and power efficiency at the same time. Instead of using existing White LEDs (which have yellow phosphors) that produce a broad light spectrum that makes it hard to efficiently produce saturated colors, Quantum Dots directly convert the light from Blue LEDs into highly saturated narrow band primary colors for LCDs. And the icing on the cake is that their colors are precisely tunable during manufacture, which means they can produce the exact colors needed for high image and picture color accuracy. This eliminates the lopsided Color Gamuts and White Point errors that are present in most existing displays.Read More
ST. PAUL, Minn.--3M announced today it is in the final stages of scale-up for its new 3M™ Quantum Dot Enhancement Film (QDEF). The new film allows up to 50 percent more color than current levels in liquid crystal display (LCD) devices. 3M has teamed with Nanosys, Inc., to produce the 3M QDEF solution specifically to deliver more color, and to make devices such as smart phones, tablets and televisions, lighter, brighter and more energy efficient.Read More
Companies to Develop Quantum Dot Technology for LCDs
Palo Alto, Calif., and St. Paul, Minn., June 6, 2012 – Nanosys Inc. and the Optical Systems Division of 3M Company are joining technologies to provide wide color gamut technology for consumer electronic displays, allowing Liquid Crystal Displays (“LCDs”) to display 50 percent more color.
3M and Nanosys will work together to commercialize Nanosys’ Quantum Dot Enhancement Film™ (“QDEF”) technology. QDEF is a drop-in film that LCD manufacturers can integrate with existing production processes. It utilizes the light emitting properties of quantum dots to create an ideal backlight for LCDs -- one of the most critical factors in the color and efficiency performance of LCDs.Read More
