When TCL became the world's top three television manufacturer with over 20 million TV shipments in 2016, it was the glory of the world's top TV manufacturers, and the "Quantum of Lights" jointly organized by the China Electronic Chamber of Commerce and the TV Technology Innovation Alliance. Bright Vision - The 2017 International Quantum Dots Display Industry Development Forum was the center of the stage. The OLED builders were exploring the conclusions of the forum on quantum dot display technology.
As a quantum dot competitor, OLED has gained a good reputation in the past two years. TV manufacturers headed by Skyworth and Sony are proactively optimistic about the OLED or future market technology.
Any innovation in color TV technology is accompanied by great controversy. The root cause lies in the fact that each of them hopes to use new technologies to build their right to speak and lead the industry. Between OLED and quantum dots, this controversy divided from the domestic enterprise camp. Later, Samsung and Sony respectively joined quantum dots and OLEDs. The technical schools between China and Japan and China and Japan are divided.
It is not yet possible to determine who must be the winner. After all, this new technology needs to be polished and it needs market recognition. If the global color TV industry is dominated by Samsung’s technological trends, quantum dots are the future technology representatives. There are indications that Samsung is working on quantum dot technology.
European and American companies that lead quantum dot technology may usher in the best era. One of the signs is Samsung’s acquisition of US QDVision. One of the topics that must be mentioned is that Samsung's dominance of color TV in the world lies in its superior insight and its grasp of industry trends. Therefore, after Samsung acquired the US QDVision, international public opinion generally believes that quantum dots may be the mainstream of future technology.
It is understood that there are three manufacturers of sub-point materials in the world: British Nanoco, German Nanosys, and American QDVision (acquired by Samsung), among which Nanosys holds more than 300 patents related to quantum dots. In the domestic panel companies, such as BOE, China Star Optoelectronics, Longteng Optoelectronics, etc., have related research and development and production of quantum dot technology. It is believed that with the active promotion of Quantum Dot upstream enterprises and complete machine manufacturers, 2017 will be the year that QD TV will accelerate its popularity.
In addition to Samsung, Chinese companies Hisense and TCL have captured the future of quantum dot technology. Therefore, Hisense and TCL, who possess quantum dot technology, already have the “killer†that challenges the world.
Like the rebirth of the eagle, TCL rushed into the air at a faster rate. In 2016, TCL launched the industry's high-end sub-brand XESS, the top flagship XESS X1 QD TV, and won a number of international awards at the 2017 CES show.
Shortly afterwards, on the spring of March 29th, the TCL XESS X2/X3 third-generation inorganic trichromatic quantum dot TV, C2 theatre TV, and P3 gold curved TV high-end series unveiled, covering quantum dot technology, top-quality sound, curved HDR, etc. Multiple areas constitute the strongest spring product camp.
The new products were also recognized by the industry as soon as they were released, and they included “2017 German iF International Design Awardâ€, “CITE Innovative Product and Application Gold Award†and “Red Diamond Awardâ€. As the leading brand of quantum dot technology, such a high-frequency application of the latest technology and the introduction of the first product, TCL announced the return of the king with the maturity of the quantum dot display.
As early as the end of 2014, TCL launched the first TV equipped with quantum dot technology in China. It is a service that Quantum TV has become the representative of emerging display technologies.
The remarkable feature of the quantum dot technology is that the solution nanocrystals have unique photoelectric properties, which are stimulated by electricity or light and emit very pure high-quality monochromatic light of various colors according to the diameter of the quantum dots.
Peng Xiaogang, professor of chemistry at Zhejiang University, said: The inherent instability of OLEDs has led to problems such as longevity and light efficiency that cannot be harmonized at present, and the yield rate has yet to meet commercialization requirements. The quantum dots are solution semiconductor nanocrystals, which only need to be changed in size to be able to bring out the desired color, and the color purity is very high, and the stability of the crystal is also very high. This is difficult for other materials to reach, and there is no need to worry about using it. Life problem. Quantum dots may be the best luminous material that humans have ever discovered.
The market is the most impartial referee. In terms of market, the actual performance of quantum dot TV is much better than the early introduction of OLED TV in the past two years. According to the data from China Yikang, the retail sales of quantum dot TVs in 2016 were more than seven times higher than those of OLED TVs. In the first week of 2017, QD TV's retail penetration rate reached 4.77% in the color TV market, while OLED TVs only achieved a 1.22% retail penetration rate during the same period.
Relatively speaking, OLED TVs have been on the market four years ago. The advantages of promotion and publicity are even greater, but they are still ranked by QD TV. This shows that the same is an emerging display technology. In the aspect of consumer concern, OLED is organic. The inherent short lifespan of materials and the low yield rate are doomed to difficult quantum dot technology. TV companies have been destined to be widely accepted by the market when choosing next-generation display technologies.
Zhang Shaoyong, manager of TCL Multimedia Product Center, stated that quantum dot technology significantly improves the quality of color, brightness, and screen life, and directly brings consumers a unique visual experience.
In the intense game of color TV technology, the advantages of quantum dot display technology are favored. Taking TCL spring XESS as an example, the third-generation inorganic trichromatic quantum dot display materials on its X2/X3 series have the advantages of “high, pure, longâ€.
"High" means high color gamut. A new generation of ultra-thin quantum dot TVs uses inorganic trichromatic quantum dot luminescent materials. The color gamut coverage is as high as 157% (BT709) and can represent 1.07 billion colors. Pure is color purity. The purity is about 37.5% higher than that of OLED, which is 58.3% higher than that of ordinary TV. The “long†color is long and the inorganic three-color quantum dot luminescent material can ensure the color does not fade for a long time and the color lasts for 60,000 hours.
The stability of quantum dots will not allow Chinese companies to miss opportunities. Therefore, using Quantum Dot Technology together with Samsung and Hisense to shake the future will build an era in which the future belongs to them.
Interestingly, Samsung, TCL and Hisense occupied three of the top five global TV sales in 2016. They jointly raised the flag quantum dot technology, and their intention and the affirmation of this technology are self-evident.
Actually, quantum dot technology will not only change television products, but will also change aspects such as biomedical care and lighting related to the future of humankind. It is a revolutionary technological breakthrough in the long course of human history evolution and represents the real future of science and technology. .
As a revolutionary technology influencing the history of humankind, quantum dot technology will completely change people’s way of life. At the same time, a new round of scientific and technological revolution will also be staged.
The height of the nation being implemented is that TCL and Hisense are shouldering the mission of the country. Quantum dot display technology has been given the focus of the national "13th Five-Year Plan." "QDs light-emitting display of key materials and devices" selected "strategy" "Advanced electronic materials" key special projects.
When other color TV companies are still standing in the OLED or quantum dot technology team, TCL has already stood in the first camp in the world.

Divide an optical jumper into two to become two optical pigtails.
The optical jumper refers to the optical connection line with the optical fiber movable connector installed at both ends of the optical fiber or optical cable. It is usually used for fiber patching or switching in distribution equipment or between optical equipment, and the length is usually no more than 10 meters.
It is a popular and common saying in the industry that when the connecting wire is an optical cable (indoor optical cable), it is called an optical fiber jumper, and when the connecting wire is an optical fiber, it is called an optical fiber jumper.
In mobile communications, coaxial cable jumpers have special product standards, while optical jumpers are different. Optical jumpers do not have special product standards. Because the attenuation of optical fibers is very small, and the length of optical jumpers is not long, the optical fiber attenuation is negligible. Therefore, the optical fiber movable connector standard is also used as the optical patch cord standard in practice. Some content of the optical fiber movable connector is different from the optical patch cord. However, in the long run, the industry has already considered the optical fiber movable connector standard That is, it is the standard for optical patch cords.
