China has a "world first" that makes many people feel like needles.
According to a study published by the World Health Organization in 2018, there are 600 million myopia patients in China, and the myopia rate of adolescents continues to rank first in the world. Since the pandemic this year, many students have completed their studies through online education, how much has children's eyesight been affected during this period?
The Ministry of Education's survey of 14,532 people in 9 provinces shows that compared with the end of 2019, the myopia rate of students has increased by 11.7% in the past six months, of which the myopia rate of primary school students has increased by 15.2%, the myopia rate of junior high school students has increased by 8.2%, and the myopia rate of high school students has increased by 3.8%!
Protect your eyes, it's time!
Voices from the scientific community
Eye protection has become a concern of the whole society, and many consumers regard "healthy eye protection" as the "first indicator" of choosing television. What kind of TV is good for protecting eye health? On September 19, at the second global laser display technology and industrial development forum, Xu Zuyan, an academician of the Chinese Academy of Engineering, interpreted the mystery of laser TV "healthy eye protection".
Xu Zuyan, academician of the Chinese Academy of Engineering
Xu Zuyan said that first, from the perspective of imaging principle, laser display uses reflective imaging, the light received by the human eye is very soft, and there is no edge effect between pixels, which can achieve full pixel luminescence, effectively reducing the light intensity within the unit area, and it is not easy to cause visual fatigue in the human eye for a long time.
Second, the brightness of the laser TV is moderate, between 300-400 nits, located in the linear area of the best visual perception of the human eye, and the viewing comfort can show high color saturation and delicate color changes.
Xu Zuyan said that the laser has high brightness, good directionality, good monochromaticity of the three characteristics, laser display with laser as the light source represents the development direction of display technology - to the human eye visual discrimination limit, to achieve ultra-high definition, large color gamut, large number of color number of high-fidelity video image reproduction, is the only fully meet the ultra-high-definition display international standard BT.2020 display technology, the mainstream of the next generation of display industry is laser display.
Previously, a group of comparative evaluation results by the ophthalmology expert team of Peking Union Medical College Hospital and the Saixi Laboratory of the China Electronics Technology Standardization Institute showed that the laser TV visual comfort measurement is better, which is more conducive to protecting the health of the eyes.
Voices from governments and industry associations
The recognition of laser TELEVISION by the scientific community has brought strong confidence to the industry. The iterative upgrading of display technology brought about by laser display is driving a new round of structural growth of the entire color TV industry and promoting the industry to revitalize again.
Ren Aiguang, deputy director of the Department of Electronic Information of the Ministry of Industry and Information Technology, introduced that in terms of laser TV standards, the laser display device sub-technical committee of the National Flat Panel Display Device Standardization Technical Committee was formally established in August this year, and is stepping up the formulation of key standards in the field of laser display to help the overall improvement of China's laser display industry.
With the acceleration of China's standard formulation in the field of laser display, it will further enhance China's voice in the field of lasers. In terms of group standard formulation, the China Electronic Video Industry Association has issued a number of standards such as "Technical Specifications for Laser Projection TV Receivers", which have clarified "full-color laser picture quality evaluation", "laser TV energy consumption", "screen specifications" and so on. The establishment of these standards will further improve the standard system of laser TV products, which is of great significance to the healthy development of the industry.
Feng Xiaoxi, vice president of China Electronic Video Industry Association
Feng Xiaoxi, vice president of the China Electronic Video Industry Association, said at the forum, "China is in a leading position in the global market in terms of the number of laser display patent applications, the manufacturing capacity of the whole machine, and the scale of the laser TV market, and has emerged leading enterprises such as Hisense, Changhong, Guangfeng Technology, and has driven the localization process of key components of the laser display industry chain such as laser light sources, imaging chips, lenses, screens, etc. A vibrant and prosperous laser display pattern is taking shape." ”
Voices from industry
As the industry leader of laser TV, Hisense will mass-produce screen acoustic laser TV next year, launch 8K laser TV and commercial laser TV with more than 10,000 lumens, share 1,000 patents with the industry in 5 years, and launch a laser TV production line expansion plan in Qingdao, while putting into production laser TV overseas, further consolidating the position of laser display industry leader.
Zhou Houjian, chairman of Hisense Group
Zhou Houjian believes that "laser display is showing the characteristics of Moore's law, the explosive growth of the market, depending on the cost reduction of core components and the degree of activity of innovative grafting, we call on more chips, lenses, optical materials, screens, lasers and other companies to join this circle of friends, the more players, the larger the market; the larger the scale, the more obvious the marginal benefits." ”
Other heavyweight guests from the industry who hold the same view as Zhou Houjian, Zhao Yong, chairman of Changhong Group, Bo Lianming, president of Guangfeng Technology, and new representatives such as Samsung at the forum site.
Zhao Yong, chairman of Changhong Group, said that the unique characteristics of laser display such as large-screen display, immersive experience, high color gamut, high picture quality and healthy environmental protection will promote the rapid tricolorization of household lasers, and propose that global laser display industry chain enterprises strengthen technology development and collaboration, strengthen the construction of supply chain system, jointly strengthen the laser display industry, and promote the rapid development of the industry.
Zhao Yong, chairman of Changhong Group
The "circle of friends" of laser TVs is constantly expanding. Since the first forum last year, in the whole year since the first forum, with the continuous promotion and innovation of Hisense, Changhong, Guangfeng and other enterprises, the technological breakthroughs in the industrial chain such as Texas Instruments, Riya and Ricoh, as well as the addition of global mainstream color TV manufacturers such as Samsung, LG, and Sony, the global laser display circle of friends is full of vitality, and the laser display has shown a strong trend of competing for spring.
The data is the best proof
Since the beginning of this year, multiple factors such as the new crown epidemic, the price war of the whole machine and the price increase of the panel have been superimposed, the overall downturn in the color TV market, the profitability has continued to decline, and lcd TV after more than 20 years of development, its technology has touched the ceiling, it is difficult to achieve a breakthrough. At the same time, a new round of consumption upgrading has accelerated, and user demand has changed from a single functional demand to a demand that pays more attention to quality and health, and industry changes are about to occur.
Aowei cloud network data show that the compound growth rate of laser TV from 2015 to 2020 reached 213.8%, from January to July this year, the overall retail volume of China's color TV market fell by 9.0% year-on-year, while the retail volume of laser TV increased by 77.5%, which is the only category in the color TV market to achieve positive growth.
"Laser displays that focus on the full-screen connection of the home are redefining the way space and product, space and people are connected." Wu Sheng, founder of the scene lab, judged that laser TV is a new species of screen, and the color TV industry just needs the stimulation of new categories.
Jiang Nanchun, Chairman of Focus Media
Jiang Nanchun, chairman of Focus Media, pointed out that healthy life and high-end upgrades are the topics that have won current consumers, and the eye protection, large screen and rich colors of laser TVs have successfully stepped on consumer pain points.
Financial commentator Liu Ge said that media and consumer attention has soared, and the Baidu index of Hisense laser TV alone has increased by 793% in the past year, and the popularity of laser TV may have just begun, and the imagination space is huge.
As Zhou Houjian, chairman of Hisense Group, said, "We are hearing the knocking on the door of the laser era more and more clearly!" "From the competition for spring to the real blossoming of a hundred flowers, the road is still tortuous and long, but the tipping point of the laser TV market outbreak has arrived."
