Recently, Blu-ray-resistant TVs have entered our field of vision. Cool has developed anti-Blu-ray televisions. Previously, Konka, Skyworth and Philips have all launched TV products with pan-blue eyes. Is there any need to prevent Blu-ray? In fact, the answer is not as simple as "yes" or "no". The different groups of people and different scenarios that they face need to be viewed in a dialectical manner.
Every day, we face more and more screens. We can simply list which screens we have dealt with from morning to night: Get up in the morning and hold a mobile phone to brush in a circle of friends, brush the news on the way to work, and the company has been staring at computers until After work, go home to watch a TV at night, and brush a wave of friends before going to bed.
Children who are developing are actually less likely to face the screen than adults. In particular, the "king of pesticides," which is popular with schoolchildren and female college students, has been making more and more time for children. Many children have their own mobile phones, and even if they do not, young parents' mobile phones also have this game. Today's children's breaks are filled with various tutoring and training activities, and the limited leisure time is filled with various “screensâ€.
Imagine the future of life, the screen will be more and more. With the development of flexible display technology, future displays will be "ubiquitous." In the future, the car interior decoration space may become a surrounding display space; the home environment will use more than one "wallpaper screen" to display different information; a variety of work scenes are inseparable from the display screen.
The white paper “National Vision Health†published on June 5th, 2016 shows that among the total population over 5 years old in China, the number of patients suffering from refractive errors was around 500 million in 2012, of which more than 90% of refractive errors were not myopia. About 450 million. Primary school myopia rate has reached as high as 46%. Without effective policy intervention, by 2020, the prevalence of myopia in the population over 5 years of age in China will increase to around 51%, and the number of patients suffering from illness will reach 700 million.
The rapid growth of myopic patients over the years has not been linked to the increasing dependence of humans on the screen. Obviously there is a relationship, but people will inevitably need to use the portable technology brought about by progress. If you cannot refuse, you will need to see how you can make better use of it. Therefore, it is necessary to prevent Blu-ray from becoming more and more burdensome on the screen, especially for children and adolescents who are developing.
About Blu-ray can be simple science. The white light we see in our daily lives is actually composed of visible light such as red, yellow and blue. The red wavelength is 600-700nm, the yellow wavelength is 500-600nm, and the blue wavelength is 400-500nm. The shorter the wavelength, the higher the energy and the stronger the penetration. Therefore, we often feel dazzling is the short wavelength, high-band blue light.
In addition, in various LED light-emitting display devices in the daytime, white LEDs need to be turned white by blue LED+phosphor powder, which has become a hard-hit area for blue light. In order to make the display device "look very bright", the manufacturer lets the LED emit more blue light. Because the more blue light is emitted, the higher the color temperature is, the brighter it is, and the cold light LED is the best choice. It not only saves costs but also looks "light."
However, not all blue light damages the retina. It is only focused on an energy peak at the wavelength of 450 nm. The blue light around this is harmful blue light.
High-frequency blue light reaches the cornea directly, so when you stare at the screen for a long time, you will experience fatigue, dryness, and tingling. It is a signal of eye self-protection. In addition, Blu-ray will indirectly cause harm to human health. Give an example of a life scene:
When you are sleepy late and you are thinking of falling asleep, you will still pick up your mobile phone and use your microblogging and circle of friends. You will find that your sleepy intentions are diminishing, and it may even make it difficult to fall asleep. That's because there is a kind of cell in our retina that is very sensitive to blue light. If it comes into contact with a lot of blue light, it will be like the signal that the brain is passing now. In addition, blue light also inhibits the secretion of melatonin, which affects the quality of sleep. So lack of sleep, eye fatigue will also increase, but also produces a large number of various problems, which is equivalent to the indirect effects of blue light.
How to effectively prevent blue light? Probably divided into three directions, debug color temperature, adjust the backlight, replace the luminescent material.
Current software such as f.lux, Night Shift, and a variety of Blu-ray filtering software utilizes the “debug color temperature†method. This is the lowest-cost method of filtering blue light, and it is also the worst. It completely suppresses Blu-ray. Used classmates all know that the mobile phone immediately became a "yellow screen," which greatly affected the viewing experience.
How do you filter out harmful blue light without affecting the color and picture quality of the screen? As we mentioned earlier, the wavelength of harmful blue light is concentrated at 450 nm. So the best way to do this is to improve the "light-emitting material."
At present, TV manufacturers in China open up with the University of California, Optoelectronics Materials and Materials Laboratory, and jointly developed a blue LED lamp beads, using spectral translation to convert 450nm harmful high energy shortwave blue light to 460nm harmless longwave Blu-ray, so that both the harmful blue light is avoided and the blue light does not affect the normal color.
You can verify this kind of innovative method from light-emitting materials through a special filter shooting method. This filter device can shield most of the light with weak penetrating power, such as red and yellow light. The more penetrating light will be captured by the camera, such as blue and purple. The camera shot through this filter shows more blue-violet light, indicating that the more blue light the TV emits.
Although there is no clear experiment to testify how much Blu-ray damages the human eye, we may not be able to take it lightly because LED screens have been around for a long time and people have not been able to see the long-term effects. The blue light emitted by the sun is much higher than the display device, but how many people really look at the sun? The eye is basically the reflection of light, but the screen light is a real shot into the eye. And with the increase in the prevalence of myopia among young children, the Blu-ray problem will certainly be put on the table.
The "screen" of modern life takes up too much of our time, and anti-blue light has become a remedy. But in fact, better protection of eyes is scientific eyes and reasonable rest. But for children who cannot resist temptation, workers who need to face the screen for a long time, and hobbyists who are hobbyists, anti-Blu-ray is really necessary.
