Quantum dot display technology has been available since the 1990s, but it has only recently become popular in the television market. LCD panels have been developed for several decades. The main improvement is the development of backlight technology. LED backlighting has now become mainstream and has better display effect than traditional cold cathode fluorescent lamp backlights. Obviously, LED backlighting is not a panacea. The so-called “White LED†spectral range is very wide. Therefore, in order to display more saturated red, green, and blue, more precise dimming technology is needed, and there are also bottlenecks. Considering that quantum dot technology can bring higher energy efficiency and color performance while reducing costs, it may soon become the hottest trend in the high-end TV market.
The self-luminous OLEDs have better color reproduction effects, but the cost is very high, the market acceptance is low, and mass production on a large scale is not realistic. Quantum dots are a more efficient display technology in LCD technology. Quantum dots can convert pure blue light sources to red and green, suppress color casts, and achieve a more balanced three-primary output. At the same time, its power consumption and cost are lower than those of OLEDs.
The so-called quantum dot is a kind of nano material, a kind of special attribute semiconductor material. Its role is to decompose light in a highly efficient manner and produce "very real" colors. At the same time, quantum dots are a low cost, but higher quality alternative technology. At present, there are several different ways to integrate quantum dots into the display. LG, Samsung, and 3M use quantum dots diffused on a thin film and then stacked on the film under the display; the other way is to smear the quantum dots on thin tubes, which are mainly used in sidelights. LCD backlight.
In traditional LCD TVs, white light passes through color filters and generates images by bending red, green, and blue light, and projects them on pixels. However, this method has its own limitations, and quantum dots can enhance the claimed white light of LEDs.
The idea behind this technique is that the color produced by the light passing through the quantum dots changes depending on the width of the dots. Since the size of quantum dots can now be precisely controlled, the light they present will be just right.
Quantum-dot TV market has huge business opportunities
According to the latest research from IHS DisplaySearch, in order to increase the consumer value of the LCD TV market, 4K Ultra High Definition (UHD) enhanced color LCD TVs adopting QD (Quantum Dot abbreviation) technology will be launched in 2015, and global shipments are expected to reach 130 Million. By 2018, QD TV shipments will increase to 18.7 million units.

According to industry analysts, LCD technology continues to innovate in order to bring more added value to consumers, although LCD technology arbitrarily dominates the television industry. With more and more rich and colorful television content, the launch of 4K ultra high-definition television is bound to set off a new wave of technological innovation.
For QD TV, Paul Gray, director of European research at IHS DisplaySearch, believes that it is an innovative technology used by the LCD industry to create more realistic images that are very close to the full human eye. The broadcaster is finalizing the content of the ultra-high definition television, but it is certain that they want to provide more TV content for UHD picture quality, not just pixel enhancement. Regardless of a person's visual acuity, richer colors can be applied to any size screen, and the subtle shadows produced can increase the realism of the screen. Quantum dot technology is a response to the OLED technology challenge in the LCD industry. At the same time, it also proves that the LCD industry technology still has room for innovation.
With TCL taking the lead in releasing quantum dot TVs, Samsung, Hisense, and Changhong have stated that Quantum TV will be launched in 2015. Quantum-dot TV will become the focus of this year's color TV industry, and it will also become the vane that will lead the development of color TV market in 2015. It can be seen that every TV brand manufacturer in the world has spared no effort in launching Quantum Dot TV. This year's Quantum Dot TV market is vast and its business opportunities are huge.
Quantum-dot TV will dominate high-end color TV market
Currently, only three sub-dot manufacturers, Nanoco, Nanosys, and QDVision in the United States, are leading the quantum dot display technology. Among them, Nanoco has partnered with Dow Chemical in the cadmium-free technology to market the quantum dot market. Since the quantum dot upstream material is mainly in the hands of foreign-funded enterprises, in 2015, color TV manufacturers used different technology and cooperation vendors to produce quantum dot TVs. Samsung's quantum dot backlighting materials to be mass produced will come from Nanoco and Dow Chemical. LG, Sony, and TCL will collaborate with QDVision, while Hisense and Changhong will select Nanosys and 3M. Among them, Samsung and China's TCL have promoted quantum dot TV most actively.
TCL has introduced Quantum Dot TV H9700 to consumers around the world, spurring many brands at home and abroad, such as Samsung, LG, Sharp, TCL, Hisense, and Changhong, to compete and follow. The era of quantum dot TV leading high-end color TV market has come. Quantum dot technology has gradually matured. As the ultimate form of LCD TVs, it will be positioned in the high-end color TV market. Differentiated products using quantum dot technology will not only become a growth point for color TV manufacturers, but also the biggest bargaining chip for LCDs and OLEDs.
Quantum-dot TV is favored by manufacturers because the display device with quantum dot technology has a wider color gamut and higher saturation, and its coverage color gamut exceeds the standards required for high-definition television, even compared with OLEDs. Also no less. Gao Hongjin, a professor at Tsinghua University, said that applying quantum dot light principles to LCD backlighting has the potential to truly improve the quality of liquid crystals and reduce the gap in color gamut between LCDs and OLED displays.
TCL aggressively rushes into the quantum dot TV market
Quantum-dot TV has become the focus of competition for color TV manufacturers around the world. At the same time, it has also been concerned by panel manufacturers in China to speed up the pace of quantum dot technology research and development. The upstream panel companies such as BOE, Huaxing Optoelectronics, and Longteng Optoelectronics are all engaged in R&D and production of quantum dot technology.
The world's first Quantum Dot TV, released by TCL, uses a quantum dot display developed by Huaxing Optoelectronics. Guo Yizheng, director of R&D center of China Star Optoelectronics Technology Co., Ltd., said that China Star Optoelectronics has the ability to supply self-developed quantum dot LCD screens, and it can display large-scale shipments of sub-dot screens. According to the information released by academician Ouyang Zhongcan of the Chinese Academy of Sciences, China's BOE's QD backlight technology R&D progress is also relatively smooth, and will soon be introduced into the mass production phase. Longteng Photovoltaic Associate Cai Zhicheng stated that Longteng Optoelectronics is currently working with domestic LED manufacturers to apply quantum dot technology mainly in the 19-inch to 27-inch display area. In order to apply QD technology to the TV field, it is also necessary to solve problems in the production environment, dry humidity, and reliability.
On January 6, 2016, TCL released the world's first high-end-terminal QUHD quantum TV and flagship product X1 at CES2016. According to TCL, QUHD TV adopts quantum dot technology to achieve a breakthrough in display technology from the micron level of OLED, ULED, etc. to QUHD nano level, achieving 110% NTSC color gamut.
With a color gamut of 110%, the brand's first product, the TCL X1 TV screen, is 65 inches in size with a circular bezel and a thickness of only 15.9mm. At the same time, an integrated design is applied to the back cover; the TV is also equipped with a ha Mankadon speakers, 6 independent units, also have Bluetooth installed on the TV, allowing you to play music directly from your phone. In terms of display, TCL X1 uses Dolby's latest HDR technology and uses partitioned backlighting technology. The entire screen has 228 partitions and uses TCL's unique algorithm. According to the official introduction, TCL Quantum Image Processing Engine consists of five core technologies, including precision color reproduction technology, S2H dynamic enhancement, and hybrid dimming. S2H dynamic upgrade solves the problem of insufficient HDR source, so that ordinary SDR sources can also exhibit HDR features when playing on HDR TVs. The latter restores the motion trajectory of the original picture, and the picture compensation is more smooth.
Samsung fights for quantum dot TV market
While local panel makers are rushing into the quantum dot display market, South Korea’s Samsung will also launch a full-strength sub-destination TV market in 2015. Kim Hyun-seok, head of the Samsung Electronics Television Division, stated clearly: “In 2015, Samsung will not invest too much effort in OLED products, but will shift the focus of R&D to quantum dot display technology.†Samsung has high hopes for Quantum TV. Although Chinese companies have taken the lead in breaking the ice in the quantum dot field, in the following competition, Samsung will become the biggest competitor of China's color TV companies.
At the Samsung China Forum on March 2, 2016, Samsung's second-generation Quantum TV completed its domestic debut. In all new breeds, the second-generation SUHD Quantum TV is undoubtedly the most important and Samsung's flagship model in 2016. Whether it is appearance, visual experience or intelligence, the second-generation SUHD Quantum Dot TV has achieved significant The breakthrough is called "Future TV."
According to reports, the second-generation SUHD TV covers 5 mainstream sizes from 49 inches to 88 inches, with a maximum curvature of 3000mm and 4200mm, and is also the world's first curved-screen TV without borders. In terms of exterior design, the second-generation SUHD TV's main push model KS9800 is full of trends. The “Bordeaux†design, “Science and Moon†design, back-screwless design, and water back panel make this TV look like 360° without any dead ends. . It is worth mentioning that the KS9800 is also an ultra-thin curved TV, and it is also the highest technical representative of the integrated ultra-thin curved TV.
In terms of picture quality, the second-generation SUHD TV adopts the world's only environmentally friendly cadmium-free, 10Bit quantum dot display technology, reaching new heights in terms of brightness, contrast, color, etc., and being longer than the original quantum dot TV. Color life. In terms of brightness, 1000 nits of HDR technology is used to achieve higher light and dark contrast; in terms of color, the second-generation SUHD TV can display up to 1 billion kinds of purest colors.
The reason why color TV manufacturers are interested in quantum dot technology is not only because they can effectively solve the problem of high color gamut but low brightness of the panel, but also because QD TV has advantages over OLED in high color gamut and is a competition between LCD TV and OLED. The best solution. Ouyang Zhongcan said: "The use of quantum dot optical materials between the backlight and the LCD panel can enable the color gamut to reach or exceed the OLED level. At the same time, because it is possible to eliminate the polarizer on the light source side, quantum dot technology It is expected to manufacture LCDs at a lower cost."
Quantum dot TV camp challenges OLED TV
At present, the camps represented by Samsung, TCL, and Hisense are making a fuss about display technology, hoping to enhance the effects of liquid crystal display through quantum dots, while the other is based on the camps represented by LG and Skyworth, and they stand behind the next-generation display technology, OLED. Judging from the layout of major manufacturers, the competition of different factions in 2016 will continue. In Wang Yulin’s opinion, QUHD has the characteristics of the next generation of televisions. The core is to use quantum display materials to fully innovate television from light sources. On the one hand, due to the use of mature inorganic materials, the fluorescence lifetime is longer and there is no need to worry about product life. On the other hand, the color gamut of QUHD is more than 10% higher than OLED.
Although quantum dot TV has many advantages in terms of technology, quantum dot TV has not reached the expected market scale in the past two years because of cost and material constraints. Quantum-dot TV's current penetration rate is still very low, and it is expected to only reach about 5% this year. It is technically good, but the relatively simple supply chain makes it difficult to reduce costs. In fact, quantum dot films are currently monopolized by foreign companies. This is the biggest problem that Chinese companies have encountered when developing this technology. Globally, three sub-dot manufacturers, namely Nanoco of the United Kingdom, Nanosys of Germany and QDVision of the United States, are leading the quantum dot display technology. The high cost of quantum dot materials has deterred many television manufacturers.
Dai Qingsong, vice president of millet television, said quantum dot technology can make TV color gamut more than 100%, but a quantum film will increase the cost of 30 US dollars. Therefore, all traditional manufacturers apply it to flagship products, and it is impossible to lay out all products from low-end to high-end products. In addition to the cost issue, quantum dot TV technology contains “cadmium†elements that have been a hot topic in the industry. According to the EU RoHS regulations, the use of cadmium-containing quantum dot TVs will be banned after 2016. Many countries’ environmental standards require that Cadmium, which currently has fewer cadmium-free quantum dot suppliers, makes the prospects for quantum dot TV development controversial.
According to Mustafa Ozgen, CEO of QD Vision, CdSe QDs are safe products that are fully RoHS compliant. As a highly efficient material, the results of commercialized product evaluations have been validated to verify the differences in material performance. Quantified. According to Mustafa Ozgen, the display industry is at an important turning point, and the penetration rate of the Quantum TV market will increase rapidly in the future.
In short, with the advancement of quantum dot display technology, Quantum Dot TV has huge business opportunities. At the same time, the future trend of quantum dot TV will dominate the high-end color TV market is inevitable.
The self-luminous OLEDs have better color reproduction effects, but the cost is very high, the market acceptance is low, and mass production on a large scale is not realistic. Quantum dots are a more efficient display technology in LCD technology.
