Samsung Applies Metal Coating to Boost QLED TV Color Performance

News Source: 

Samsung Electronics is making it clear that quantum dot (QD) technology will be at the center front of its 2017 TV product lineup, reported ZDnet.

The Korean electronic manufacturer shed some further light on its TV range, stating the reliability of its new QD material allows a color in a wider range matching those reached at higher brightness levels or those reached in OLED TVs.

Titled the “Q Project,” the business set a target resolution for 2017 that tests quantum dot materials through various methods.

The company introduced a ‘metal coating’ process, where metal is coated around the nanocrystals to form a shield to keep it more stable, circular and the same size, they said.

The crystals circular shape and size are important for raising color accuracy, insiders declined to comment on the metal used stating it was a trade secret.

TVs also hit the High Dynamic Range (HDR) at peak brightness of 1,500 nits, they added. There are no trade-offs between color and brightness. Increased brightness will affect the color volume, and vice-versa. New models are able to achieve a wide color volume—covering all of DCI-P3 standard color space—even at 1,500 nits, they said.


The new QD TVs are capable of achieving a wide color volume that covers all of DCI-P3 standard color space, even at 1,500 nits, they added. Compared to traditional WRGB displays’ 67%, using QD enabled Samsung to achieve 104% color space of the standard, they added.

The TVs will be branded QLED, while the SUHD used for 2015 and 2016 models will be the dropped. The new brand represents the quantum dot's importance, functions and advantage over rival technologies better, they said.

The world’s largest TV maker, Samsung, launched QD LCD TV as a premium line-up at CES 2015 that it branded as SUHD TV. Runner up LG Electronics also used OLED for its high end TVs, while Sony plans to launch OLED TVs, using LG Display panels.

Using QD materials advantages over OLEDs include they are less costly to make, QD process can be added to existing LCD production lights, have a longer lifespan, and do not suffer “burn-in” issues. Although, OLEDs are excellent at displaying black, OLEDs main issue is high costs, long playing time that results in images burnt in on the screen.

OLED is a diode emitting light that does not require backlight, and the name QLED indicates some speculation on whether Samsung succeeded in making the crystals emit light in a similar fashion as OLEDs.

Samsung confirmed with ZDNet that the quantum dots are not self-emitting lights. The new TVs similar to predecessors will have a QD film layer atop a LCD with LED as the backlight.

Company insiders commented TV manufacturers are showing strong interest in QD technology and making preparations, they expect after CES more companies will join the “QD camp”. Samsung is willing to collaborate with these firms, they said, suggesting they should supply QD materials.

Chinese TV makers TCL and Hisense that rank respectively in third and fourth place among top TV vendors, are also making progress in QD TVs.

Samsung is investing in QD technology and acquired QD Vision in late November for US $70 million.

The South Korean tech giant is developing quantum dot nanocrystals that do not use the hazardous component Cadmium.

Quantum dots are applied in monitors as well as in curved monitors to be unveiled at CES next year.
