HDTV Test: Do 4K Blu-ray Discs Contain Colours Outside DCI-P3?

TV reviewer and professional calibrator Vincent Teoh wanted to find out if there are any examples of Hollywood-produced content that take advantage of the full BT.2020 color gamut capabilities of the UHD Blu Ray format. Using the out-of-gamut color mode on the Sony HX310, he went looking for “zebra stripes” (a warning that the content falls outside of the monitor’s DCI-P3 gamut) in popular content.

The results may suprise you.

Nanosys invites consumers to explore the beautiful world of Quantum Dot colors with abstract short film “Quantum Flows”

New York, NY, June 11, 2019 – The abstract short film “Quantum Flows,” debuts today at the 8K Display Summit 2019 in New York City. Shot entirely in stunning Rec.2020 8K HDR by Director Phil Holland, the film explores the vividly colorful world of Nanosys’ Quantum Dot nanocrystals few consumers have seen.

Nanosys Quantum Dot technology is typically used to produce high quality, vibrant images on Quantum Dot televisions from top brands including Samsung, Hisense, TCL and Vizio. For the first time, this film shows the nanomaterials in their vividly colorful natural state, outside of the TV.

HD Guru: Rec. 2020 Color Gamut Achievable Soon with Quantum Dots

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.

Advances in Displays: Quantum dot film lets LCDs express 50% more color

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.

"Quantum Dots are going to revolutionize and reenergize LCDs for the next 5+ years," Dr. Ray Soneira of DisplayMate

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.

3M and Nanosys to Bring More Color to Consumer Electronic Devices

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.
