Resurrection in the display area, quantum dot technology has entered the episode
OFweek smart home network news TV industry has always been contested. From the black and white television of 20 to 30 years ago to the curved QLED TV of today, the pace of display technology innovation has never stopped. On April 13th, at the Beijing Yanqi Lake International Conference and Exhibition Center, the “Quantum Lights Horizons - 2017 International Quantum Dot Display Industry Forum†organized by the China Electronic Chamber of Commerce marked a watershed for the development of the display panel industry. Since then, OLED and QLED have launched a comprehensive competition, and QLED TVs based on quantum dot technology have increasingly demonstrated excellent performance and are rapidly moving into the homes of ordinary people.
Display technology continues to change, QLED TV favored by the market
After undergoing the "three consecutive falls" from 2013 to 2015, the color TV industry finally ushered in 2016. However, as far as the industry as a whole is concerned, it is still unable to shake off the shadow of overcapacity. According to calculations, the total new investment for display panels in China will exceed RMB 220 billion in 2017. In the midst of the huge production capacity impact, how to win the market with the highest cost performance and best color quality is a problem that all manufacturers have to face.
For a long time in the past, no matter whether it is a color TV display panel or other monitors, it has failed to truly restore the colors seen in our eyes. With the constant change of technology, the competition in the high-end market is no longer limited to the competition between manufacturers and manufacturers, but is an upgrade to the competition between QLEDs and OLEDs.
At the 2017 International Quantum Dot Display Industry Forum, Liu Yufeng, vice president of the China Electronic Chamber of Commerce, mentioned that based on their findings, the market demand for global quantum dot materials will grow from 2.5 million square meters in 2015 to nearly 2500 in 2020. Million square meters, the compound annual growth rate will exceed 50%, quantum dot technology has become the backbone of color TV display.
Thanks to the rapid progress of QLED technology, this year Samsung introduced a huge lineup of QLED TVs, including 4 series and 8 models, spanning 55-inch to 88-inch and other sizes, and the display can also be freely selected. Fully led the development of QLED TV. At the forum, channel partners such as Samsung, TCL, Hisense and Gome, Suning, Jingdong, and Tmall have signed on site. This year, the quantum dot TV subscription will reach 10 billion yuan. At the same time, the quantum dot alliance with Samsung as the core was formally established to jointly share the industry dividends brought about by quantum dot technological innovation.
At the same time, huge market prospects continue to drive front-end R&D. It is understood that in the domestic panel companies, such as BOE, China Star Optoelectronics, Longteng Optoelectronics, etc. have quantum dot technology related to R & D and production. With the active promotion of upstream companies and machine manufacturers, this year will be a year when QD TV will accelerate its popularity and expansion.
The indicators lead the industry, quantum dot technology into high-end TV standard
In fact, the research on quantum dot technology started as early as the 1970s, and it has reached the mature stage of research and development and the promotion period of products. In essence, QLED TV can quickly capture the heart of consumers, the key is that it can change the principle of light emission of traditional LCD panels, nano-level quantum dots can receive more light and electricity stimulation, change the luminous color, with Give the display more realistic color scenes. In the forum, Samsung, TCL, etc. have all demonstrated their own QLED TVs. Through analysis, we can see that QLED has two significant advantages:
1. Can meet the demanding requirements of extreme colors. QLED TV display has excellent performance in color gamut, contrast, brightness, color accuracy, and display digits, which can meet the user's demand for extreme color. At the forum, the Digital TV Standardization Testing Center of the Ministry of Industry and Information Technology has disclosed the display level of quantum dot TVs. The white field brightness, peak brightness, color gamut coverage and dynamic contrast ratio (HDR) of quantum dot TVs far surpass those of traditional LCD TVs. And OLED TV. For example, the Samsung QLED TV panel can exhibit peak brightness of up to 1,500-2,000 nits, while the OLED TV peak brightness stays within the 500-600 range. At the same time, Samsung QLED light quality sub-dial TV is not only the world's first TV that can reproduce 100% color rendering volume, but also has a wider viewing angle.
2. Can provide a longer life. Compared with the same price of the product, QLED TV has a very significant advantage is the long life, the picture is stable. Because unlike inorganic materials such as OLEDs or other materials, QLEDs use inorganic materials that do not degrade over time, providing nearly unlimited image lifetime.
It can be said that after nearly half a century of development, quantum dot technology has accumulated accumulated energy in the display area. At the beginning of April, CCTV’s Evening News also specifically reported this and “liked itâ€. Zhu Lei, deputy secretary-general of the Shenzhen Flat Panel Display Industry Association, said, "Quantum dot technology has huge advantages in color gamut coverage, precise color control, longevity, and power consumption." Professor Peng Xiaogang even said with excitement: "QLED may be human The best luminescent material found so far."
summary
It is not difficult to imagine that quantum dot display technology has raised the picture quality of liquid crystal display to a new height. With the extremely cost-effective function and design, QLED TV has gradually become the mainstream of the market. Brand manufacturers represented by Samsung have already tasted the sweetness of quantum dot technology and achieved first-mover advantage in technology reserves and market expansion. It is worth noting that QD technology does not stop at the display panel. Researchers are beginning to explore the application of quantum dot technology in areas such as solar cells, biomedical markers, post-production photography, and creative advertising design. The market potential in the future is enormous.
