The establishment of the Xiong'an New District has made the "News Network" a fire. It is obvious that it is important to read the news and understand the news. A few days ago, another column of CCTV, "Night News", focused on a small screen, praising quantum dot technology. What signal was released this time?
CCTV's "Night News" column praises quantum dot technology
According to reports, as a very advanced nanomaterial, the color of light emitted by quantum dots is more pure, and the color can be restored more accurately. At the same time, quantum dots also have the characteristics of stable performance and long life. In fact, in addition to the features mentioned in the report, quantum dot technology has the advantages of wider color gamut and higher brightness. Peng Xiaogang, a professor at Zhejiang University and a senior expert in quantum dots, said with excitement that "quantum dots are probably the best luminescent materials ever discovered by humans."
Although it has not yet reached the height of the "millennial plan", quantum dots, as the most promising future display technology in the industry, have attracted widespread attention from domestic and foreign color TV manufacturers. Samsung, TCL, Hisense and others have successively launched high-end quantum dot TVs, trying to lead color TVs. The industry entered the QLED era.
It is understood that the application of quantum dots in display technology mainly includes two aspects of photoluminescence and electroluminescence. Once the bottleneck of the electroluminescence technology is broken, the display and flexible display can be realized, and the display can be made like a newspaper, so that the media such as clothes and curtains become televisions, realizing the display everywhere and profoundly changing the production and lifestyle of human beings.
Quantum dot materials are not only stable, but also capable of accurately reducing color
In the current photoluminescence stage, Samsung's new QLED TV brings together cutting-edge cutting-edge technology to apply the color of light to the extreme. Samsung has given this brand new TV a resounding name, QLED light quality sub-point TV, meaning magical "quantum light", "color power."
In order to let consumers better understand the characteristics of quantum dots, Samsung has also made a very streamlined summary of its QLED light quality sub-point technology "light, long, wide". In terms of "bright", Samsung QLED TV can display peak brightness of up to 1500-2000 nits, which is 6 times that of ordinary TV and 3 times that of WOLED. In terms of "long time", unlike the organic materials used in WOLED, QLED does not suffer from degradation over time. It is durable and never exhausted, providing near-infinite image life. For "Guang", Samsung QLED Light Quality Sub-TV is not only the world's first TV that can restore 100% color rendering volume, but also has a wider viewing angle.
It is reported that this year Samsung launched a huge QLED TV lineup, including 4 series, 8 models, spanning from 55 inches to 88 inches and other size segments, and the curve is optional, fully leading the development of quantum dot TV. Thanks to Samsung's unremitting efforts and vigorous promotion, quantum dot TV penetration is increasing, showing a more promising potential than OLED TV.

According to data from NPD DisplaySearch, the global market demand for quantum dot materials will increase from less than 2.5 million square meters in 2015 to nearly 25 million square meters in 2020, with an average annual compound growth rate of over 50%; to the global quantum dot market by 2020 The scale will reach 2.5 billion US dollars, and the growth potential is huge.
In order to compete for this huge market dividend, Samsung, TCL and other manufacturers have accelerated the pace of the layout. Among them, Samsung acquired US QD Vision, one of the world's three largest sub-point material manufacturers, and further integrated its industrial chain in the field of quantum dots. Liu Junguang, vice president of color TV marketing for Samsung Electronics Greater China, said that Samsung is one of the most complete companies in the world in the entire TV industry chain. He said: "From patent technology, material research and development to quantum dot display production, to the manufacture of terminal products such as quantum dot TV, Samsung has dominated all fields of television technology." TCL also invested in Zhejiang University's Najing Technology many years ago, and is committed to the research, manufacturing and application technology and product development of new quantum dot materials.
Quantum dots are very promising in the field of display
In fact, quantum dot technology has changed not only in TV products, but also in biomedicine, food testing, lighting, communications and other fields. The QLED print display is also listed as a key technology in the 13th Five-Year Plan of the Ministry of Science and Technology. It is foreseeable that in the near future, quantum dot technology will completely change people's lifestyles, and a new round of technological revolution will also be staged.
This time, CCTV's "Night News" focused on quantum dots may be releasing signals: in the future, the prospect of quantum dots in display technology will be considerable.
