The eye-protection screen with nearly 10,000 at every turn is an anti-myopia artifact or an IQ tax?

　　China-Singapore Jingwei, October 5th (Lin Wansi intern Zhao Wei) Xiao Yun (pseudonym) has been hesitant to buy an eye protection screen for children to take online lessons throughout the summer.

"Social platforms are filled with cursive texts: children's online classes are more eye-friendly, it is very convenient to connect to a tablet phone, and the high-definition does not hurt the eyes... It really takes our mother's psychology to death." In the end, Xiao Yun spent thousands of yuan , buy an eye protection display.

　　After the arrival of the goods, Xiao Yun found that the so-called eye protection screen is equivalent to a projection. Whatever content is played on the iPad, the eye protection screen plays whatever content. As a result, the image quality loss of the eye protection screen is very large. "Eye fatigue is myopia. The culprit, so the resolution of the output picture is so low, won't the child's eyes be more tired?"

　　After the "double reduction", the 100 billion education and training market has cooled down rapidly, and traditional education hardware manufacturers and Internet giants have entered the eye protection screen market one after another.

But with the market, there is also the debate about whether the eye protection screen is an IQ tax.

　　A mother told Sino-Singapore Jingwei that the eye protection screen was "too windy" recently, and big data kept pushing relevant evaluations, but there were so many types of products, she didn't know how to start; there were also mothers who thought that no matter which product was able to provide real protection Eyes, it is better to cast a big screen to watch the TV screen.

Big factory entry

　　According to statistics from iResearch and the Duojing Education Research Institute, the size of my country's educational intelligent hardware market is expected to exceed 100 billion yuan in 2024, with a compound annual growth rate of 26%.

Parents' demand for educational hardware no longer simply focuses on learning functions, and "eye protection" has also become a new focus.

　　Sino-Singapore Jingwei searched for "eye protection screen" on the e-commerce platform and found that industry leaders such as traditional hardware manufacturers, intelligent electronic products, semiconductor display fields, and Internet manufacturers are competing for the field of eye protection screens, and they have launched different materials. Eye screens, such as "IPS paper screen", "nine-layer scattering eye protection screen", "LTPS eye moisturizing screen" and "ink screen", are dazzling.

　　During the epidemic, online courses have become "just-needed".

In the first half of 2022, seewo launched a new generation of online learning machine W2, which claims to achieve AG anti-glare, low blue light, and ultra-wide viewing angle.

　　It is understood that seewo is the brand of the education business of CVTE, an A-share listed company.

Regarding the specific technologies of "low blue light and anti-glare", seewo customer service said, "W2 adopts three types of paper eye protection technologies, which realizes paper-like anti-glare and ultra-wide-angle soft display."

　　At the same time, the customer service also claimed that the learning machine has also been certified by TÜV Rheinland for low blue light, TÜV Rheinland without stroboscopic certification, and grade A of the visual health standard of Shenzhen Saixi and Zhongshan Eye Center.

　　Traditional hardware manufacturers BBK and Dushulang also launched their own eye protection learning machines.

BBK's sub-brand Xiaocai has launched an AI eye protection tablet, the BBK tutoring machine A6.

According to the official mall of Xiaocai, the tablet is "designed for online classes".

　　In July this year, Dushulang was listed on the Hong Kong Stock Exchange.

After the "double reduction", Dushulang focuses on AI learning machines.

Take the AI ​​learning machine C50, which was introduced in August this year and introduced by the official flagship store customer service, as an example.

Dushulang e-commerce customer service said that the e-ink screen itself does not emit light, and there is no blue light stimulation.

　　BOE, the global leader in the semiconductor display field, has also launched paper-like eye protection screens such as BOE Funbook and Picture Screen E2.

　　Some learning machines also combine products with different services and educational resources.

In addition to protecting eyesight, some of the above learning machines also provide services such as subject planning, remote management of parents, and free video learning for general subjects, which are packaged and sold with learning machines.

　　Internet giants have also added eye protection smart hardware.

Baidu's "AI Life" business segment Xiaodu also launched a large-screen eye protection intelligent learning machine.

iFLYTEK and Huawei have launched ink screen tablets.

　　According to the official website mall, the above-mentioned ink screen tablet can also realize functions such as transcription, AI reading, foreign language translation, etc., and the content of notes can be synchronized to mobile phones and computers.

　　However, although the market for eye protection learning machines and display screens is hot, the revenue of some of the above-mentioned companies has declined in the first half of the year.

　　In the first half of this year, CVTE achieved an operating income of 8.98 billion yuan, a year-on-year increase of 12.78%.

The education business under the seewo brand achieved operating income of 1.698 billion yuan, a year-on-year decrease of 24.46%.

　　The semi-annual report did not specifically disclose the reasons for the negative growth of seewo's revenue, but pointed out that in the first half of 2022, affected by the domestic epidemic, China's domestic education market experienced a certain decline.

The semi-annual report quoted statistics from the "Global IFPD Market Research Report 2022 Q2 DISCIEN" that the Chinese education market shipped about 307,900 units, down 30% year-on-year.

　　Dushulang's semi-annual report also shows that in the first half of the year, students' personal tablet income was 231 million yuan, a year-on-year decrease of 23.1%.

According to the semi-annual report, the decrease was mainly due to the repeated epidemics, which affected the supply chain and dealer business to a certain extent.

　　According to BOE’s 2022 semi-annual report, revenue in the first half of the year was 91.610 billion yuan, a year-on-year decrease of 15.66%, becoming the first negative year-on-year growth in the semi-annual report after 2018.

Among them, the revenue of the display device industry, which accounted for more than 90% of the revenue, was 82.642 billion yuan, down 17.89% year-on-year.

　　BOE also stated in its semi-annual report that the semiconductor display industry continued to hover at a low level, the prices of major panel products fell, and the company's operating income declined.

　　Faced with a dazzling array of products and cool functions, most mothers pay more attention to the basic function of the eye protection screen - eye protection.

　　Sino-Singapore Jingwei found that eye protection certifications such as "TüV Rheinland Low Blue Light Certification" and "TüV Rheinland Flicker-Free Certification" can be seen on BOE, BenQ, seewo and other products. Behind it is the certification company TüV Rheinland. .

　　According to the official website, TüV Rheinland is a technical service provider.

The "Eye Comfort Certification" item is included in the "Certification and Audit" column of the official website.

　　On the 26th, Sino-Singapore Jingwei, as a display product provider, contacted the staff of TüV Rheinland Group to consult the relevant eye protection certification.

According to the other party, the eye protection certification of the monitor is divided into the lower-level low-blue light certification and the low-frequency/flicker-free certification, and the more advanced eye-comfort certification.

Most screen manufacturers can achieve low blue light certification and low-frequency flicker/flicker-free certification when selling screens, while eye comfort certification is a more dimensional and comprehensive eye protection guide and certification.

　　"That is to say, eye comfort certification not only requires low blue light and low frequency flicker/no flicker, but also requires the screen display to achieve two dimensions of ambient light management and health and comfort guidance." The staff member said.

　　The other party said that applying for certification requires sending samples to their company, and they will also inspect the factory to verify whether the factory has the ability to produce products of this level.

In addition, enterprises need to pay corresponding testing fees, and products need to fully meet the evaluation standards to obtain relevant certificate certification.

"The price of certification projects at different levels is different. The cost of low blue light certification and low screen flicker certification is tens of thousands to hundreds of thousands of yuan, and the cost of eye comfort certification is hundreds of thousands. The specific price needs to be evaluated with detailed product information."

　　It is worth noting that the staff member said that when their relevant eye protection certification was first introduced, the testing cost of enterprise products was close to one million.

Really eye protection or IQ tax?

　　With the emergence of new technologies, technology can bring more empowerment to education.

But as intelligent education hardware that finally reaches the consumer market terminal, can "eye protection" learning machines and "eye protection" monitors really protect eyes?

　　Parents are most worried about the damage to children's eyesight caused by blue light from electronic screens.

In this regard, Gu Cao, deputy chief physician of Shanghai New Vision Zhongxing Eye Hospital, said in an interview with Sino-Singapore Jingwei that blue light is part of natural visible light, and both sunlight and electronic screens emit blue light.

Blue light has a short wavelength and high energy, which can directly penetrate the lens and reach the macular area of ​​the eye, causing macular degeneration, as well as visual fatigue and affecting sleep.

Among them, short-wave blue light with a wavelength of 400-450 nanometers is the most harmful to the retina.

The strobe will not cause damage to eyesight, but it will cause visual fatigue.

　　However, he believes that

　　The China Consumers Association once pointed out that blue light exposure can only cause retinal damage after sufficient time and a certain intensity.

There is also no direct evidence that blue light causes myopia.

Therefore, parents do not have to worry too much about the so-called blue light hazard.

For some businesses to falsely exaggerate the performance of anti-blue light products, excessively interpret the harm of blue light, and sell anti-blue light products at high prices, it should be treated rationally.

　　From a technical point of view, home appliance analyst Liu Buchen pointed out to Sino-Singapore Jingwei that from the perspective of display technology,

"

　　Liu Buchen said that at present, more than 95% of display products, including learning machines and "eye protection screen" monitors that claim to be "eye protection", only have two types of screen materials: OLED screen and LED screen. Others such as Mini LED and Micro LED screen are still very popular. rare.

　　Liu Buchen further introduced that if the so-called "eye protection screen" is an OLED screen, then it itself is eye protection, because OLED emits very little high-energy short-wave blue light; if the "eye protection screen" is an LED screen, then the LED screen itself It emits high-energy short-wave blue light. This high-energy short-wave blue light is very harmful to the eyes. Even if some technical treatments are done, such as the TÜV Rheinland certification, the eye protection effect is still not optimistic.
