Electronics enthusiasts news at 8 a.m.: After price, technology and equipment, internal business and ecology, what is the next step in the TV industry? What will be the direction of development?
Recent actions by industry giants such as Samsung, LG, and Sharp give the answer – display technology. After all, no matter which screen it is, big or small, apart from the internal things, what people ultimately get is the visual experience.
As a result, a group of lonely specialized research terms have become familiar hot words. First it was LCD (liquid crystal display), then OLED (inorganic light-emitting diode), and now, it’s QLED’s turn – quantum dot display technology.
The quantum dots used in QLED are semiconductor nanocrystals. When stimulated by light or electricity, quantum dots will emit colored light. The color of the light is determined by the composition and size of the quantum dots.Therefore, peak pure color light including red light to blue light can be obtained by changing the shape of quantum dots.
Quantum dot technology first appeared in the late 1970s, which Western countries hoped to find during the oil crisis Burundins Sugardaddy An efficient photoelectric conversion technology was invented. Currently, quantum dot-related research is a very hot field internationally, with tens of thousands of papers published every year.
“Quantum dots may be the best luminescent material ever invented by mankind.” Peng Xiaogang, a professor at the Department of Chemistry at Zhejiang University, said that quantum dots are solution semiconductor nanocrystals, and each small particle is a single crystal. The size is only about one ten thousandth of a hair. You only need to change the size of the quantum dots to create the desired color, with high color purity and high crystal stability, which is difficult to achieve with other materials, and there is no need to worry about service life.
Color gamut is the measure that determines how many colors the human eye can observe. “According to the highest BT2020 standard, Apple’s mobile phone is only about 50%, which means that half of the colors cannot be displayed, but quantum dots can achieve 100% of the color gamut and restore all the colors we can perceive.” Peng Xiaogang said.
From the laboratory to the market, quantum dot TV has become a representative civilian product of current nanotechnology.
In the TV market, quantum dot technology TV entered the public eye in 2014. Through the continuous product enrichment of Samsung and other brands, after nearly three years of development, it has become an important category in the mid-to-high-end market.
Burundins Escort TCL is one of the representatives of the development of the international home appliance industry in this field. Recently, TCL released the XESS X2/X3 series of inorganic three-primary color quantum dot TVs, etc., which use a new generation of inorganic three-primary color quantum dot display materials.
Since the release of quantum dot TV in 2014, TCL has officially begun the exploration of the international marketization of quantum dots. In 2016, it released QUHD quantum dot TV to promote the civilian use, commercialization and marketization of quantum dots. . According to the first public test results of Terrat Labs, the core indicators of QUHD TV are excellent, especially the color gamut coverage is the highest value in the large database, the peak brightness exceeds the industry average by 77.9%, and the color brightness exceeds the industry average by 26%.
According to Wang Cheng, Vice President of TCL Group, the new generation of inorganic three-primary color quantum dot display materials used by TCL this time are only one-ten thousandth the size of inorganic luminescent materials, achieving color processing from the micron level to the nanometer level. level breakthrough.
“The advantages of the new generation of quantum dots can be summarized into the three aspects of ‘high, pure and long-lasting’. ‘High’ means high color gamut, and the color gamut coverage rate reaches110% NTSC; ‘Pure’ means pure color, the color purity is about 58.3% higher than that of ordinary LEDs, and can reflect natural colors; ‘Long-lasting’ means long-lasting color, the new generation of ultra-thin quantum dots are stable inorganic nanomaterials, which can The color is guaranteed not to fade and the color is durable and stable for up to 60,000 hours. “Wang Cheng said.
Industrial chain skills determine ranking. With the maturity of quantum dot technology, quantum dot TV Burundi Sugar has grown from super high Dimensions such as color gamut, color restoration, and color purity break the shackles of traditional image quality and reveal the potential of becoming a future display technology.
According to predictions from NPD Display Search, the annual growth rate of quantum dot TVs in the Chinese market. It will reach 100% and is expected to increase from 600,000 units in 2016 to 1.2 million units in 2017. At the same time, the number will also increase from 3 million units to 6 million units worldwide.
At present, domestic and foreign TV companies are in the process of quantum. Smoke has begun to rise in the structure of dot technology, and price is the core issue in achieving marketization.
In the new products released this time, TCL directly “lowered” the pricing of quantum dot TVs to ordinary consumers. Within the acceptance range. Wang Cheng revealed that the third-generation quantum dot TV has reduced thickness while improving picture quality, and has also achieved cost control through technological improvements, bringing the price of quantum dot TV into the mainstream price range for the first time.
The reason why TCL can launch new products in clusters is that it has a trump card – Huaxing Optoelectronics.
TCL’s Huaxing Optoelectronics currently has three LCD panel production lines, and its products cover all large-size TV panels. and small and medium-sized variable-position terminal panels. CSOT ranks among the top players in the world’s LCD panels, making TCL the only color TV company in the world that has completed vertical integration of the industry chain, making the supply of core components no longer controlled by others and ensuring the company’s global competition.
Even looking at the global market, there are only three color TV companies with vertical integration of the industrial chain. As the first company in the world to produce quantum dot TVs, TCL’s shipments of all products exceeded 20 million in 2016. Taiwan. In the high-end color TV market, which currently has the greatest opportunity, it is seizing the share originally belonging to Japanese and Korean giants.
However, foreign giants such as Samsung are also accelerating the research and development process of quantum dot technology in Shanghai. At the 2017 Samsung China Forum, Samsung displayed dozens of TVs of different categories, including 4 series and 8 models of QLED photo-induced quantum dot TVs, spanning multiple size segments from 55 inches to 88 inches. /p> Under the trend, China no longer follows the “display industry from CRT to LCD to OLED. The core technology has always been in the hands of foreign giants, and electroluminescent quantum dot TVs are completely dominated by Korean companies.” “Peng Xiaogang said that at present, my country’s imported backlight modules consume a very large amount of foreign exchange.
“In GuangzhiChina is not lagging behind others in terms of the first generation of luminous quantum dot TVs. If all parties in China unite to master quantum dot technology, it will break the monopoly of foreign countries. Peng Xiaogang said.
Quantum dot display technology is mainly divided into two stages: photoluminescence and electroluminescence. Based on the first stage of photoluminescence, its performance has been superior to existing TVs in terms of color and power consumption. In terms of overall results, a breakthrough has been achieved. As for the second stage of electroluminescence, Peng Xiaogang bluntly said that it will be the most powerful BI EscortsEnough next-generation display technology options
Peng Xiaogang said that quantum dot technology is developing in solar cells and bio-medical applications. , lighting and display industries and other fields have begun to explore applications, and the prospects are bright Burundins Escort. For example, in the biomedical field, different colors of quantum dots can be used. To detect multiple germs or pesticide residues at the same time, quantum dots can be used in the lighting industry to greatly improve luminous efficiency.
At present, quantum dot display technology has been tracked and paid attention to by the country’s “Thirteenth Five-Year Plan”. Among the national key R&D plans announced by the Ministry of Industry and Information Technology, the “Research on Key Materials and Devices for Quantum Dot Displays” led by Peng Xiaogang was selected as a key project of “Strategic Advanced Electronic Materials”. The Ministry of Industry and Information Technology also announced that quantum dot printed displays are a national key development key technologies. In the new wave of technology, China will no longer “follow” as before.
