Global TV manufacturers, distributors and academic institutions formed an alliance to work together to boost the QLED TV market in China, the world’s biggest TV market.
The alliance was set at the first ever QLED International Forum held in Beijing on 13th April and among other manufacturers take part in it: Samsung, TCL, and HiSense.
“QLED TV achieved 100% annual growth rate in the Chinese market and will increase from 600,000 products in 2016 to 1.2 million in 2017,” CECC -Chinese Electronics Chamber of Commerce- Vice Chairman, Liu Yufeng, said on his opening remarks at the Forum. “At the same time, the sales at the world’s market will also increase from 3 million to 6 million units. Quantum dot technology will be the major trend of the TV industry.”
Market research firm DisplaySearch estimates that global sales of Quantum dot TVs will exceed 18 million units by 2018.
Professor Peng Xiaogang of Zhejiang University summed up the significance of Quantum dots’ development quite succinctly. “Quantum dots are the best lighting material that mankind has ever found,” he explained. “The pure color representations, brightness and other features of Quantum dots are characteristics that other display technologies would have difficulties to take over.”

Samsung launched first QLED TV screens in 2016 and introduced its latest generation of QLED TVs in 2017. The South Korean company also showcased first ever QLED curved monitor at CES 2017.
However, as Liu Junguang, Samsung Electronics’ Vice President of Visual Display Business explained, an ability to portray vivid, accurate colors is not the only reason Quantum dot technology represents the future of TV.
“Because Quantum dots use inorganic materials, our displays can provide the utmost display quality without problems that leave marks on the screen, such as burn-in, or affect the lifespan of the product,” said Liu.
“It is the most suitable material for making displays,” he continued. “2017 is going to be the year when the global TV manufacturers works together to promote the QLED TV market.”
Nanosys, the leading developer of Quantum dot technology, delivered a presentation that revealed QLED’s superior visual performance. The forum also provided a venue for TV manufacturers, display industry experts and academics to discuss the state of Quantum dot technology and QLED TV’s development.

After the attending the first QLED International Forum, where companies operating in this market were hosted by The China Electronics Chamber of Commerce (CECC), distributors shared their strategies for vitalizing QLED TV sales. Samsung Electronics and other TV manufacturers signed contracts with GOME Electrical Appliances, Suning Commerce Group, JD.com, Five Star, Sundan and other distributors with the aim of boosting the QLED TV market.
Established and registered by the Ministry of Civil Affairs of P.R.C in 1988, China Electronics Chamber of Commerce (CECC) is a national corporate organization of electronic industry incorporated on a voluntary basis with companies and organizations dealing in electronic products across China.
Serving more than 4000 members including direct affiliated members, members of local branches and members of special committees, the annual sales value realized by the over 4,000 CECC members amounted in 2004 to more than 800 billion (In RMB).
Why are quantum dots so googd for TV sets?
Quantum dots are nano-sized crystals made of semiconductor materials. A nanometer (nm) is one billionth of a meter, which means these extra-small particles are smaller than 1/10,000 of a single strand of human hair.
Quantum dots can be made of different kinds of elements, but when regulated down to a size small enough, the quantum dot possesses physical properties that make it suitable for many different applications. For example, quantum dots are very efficient in absorbing and then emitting light. Based on this quality, quantum dot technology is being researched in areas such as solar panels, bioimaging, and, of course, display.
Quantum dots are photo-active; they absorb, and then emit light. And when they do, even if the dots are made of the same material, the light each quantum dot emits is a specific color (or wavelength) depending on the size of its core. For example, a quantum dot with a core of 2nm will emit a blue light while one with a 6~7nm core will emit red. The color of light each quantum dot gives off is also very stable and pure.

Quantum dots can show precise colors while the light from conventional materials ends up getting mixed with adjacent colors. This is because the spectral line width (width of each peak in the graph below) of the light from quantum dots is much narrower than that from conventional materials.
As a result, the 3 primary colors can be more clearly distinguished in comparison to conventional TVs, which helps the quantum dot display show a wide range of colors more accurately.
Another advantage of these light-emitting quantum dots is that they’re very efficient. Compared to phosphors in conventional TVs, not only are they able to produce more colors, but the photo-active property allows for better light efficiency.
