Child care living room artifact! Cool open A3 anti-Blu-ray education TV evaluation

With the continuous popularization of Internet smart devices, people are facing more and more "screens" every day. However, electronic screens such as mobile phones, computers, tablets, and televisions all release high-energy short-wavelength blue light, which will cause irreversible harm to those who have long been exposed to these “screens”, especially children who love to play mobile phones and watch television. According to the White Paper of National Vision Health, the number of nearsighted people in China is now close to 450 million, of which the primary school myopia rate is as high as 46%. It can be seen that protecting children from blue light damages should be done by every parent. How can children who are full of curiosity about the world not only protect their glasses, but also not their connection with the "screen" world?

June 6 cool development of a Blu-ray educational television - Cool open A3, gave a perfect solution. Cool open A3 uses optical anti-Blu-ray technology, a breakthrough from the hardware point of view to solve the Blu-ray problem, the harmful blue wavelengths will be translated to the harmless band, from the lamp chip to solve the Blu-ray problem. And does not affect the blue light to send out normal colors, the picture will not appear yellowish.

Cool open A3 anti-Blu-ray educational TV, also accepted the anti-Blu-ray detection of TUV Rheinland, and issued a Blu-ray certificate. (TUV Rheinland, one of the three most authoritative testing and certification organizations in the world, has more than 140 years of experience. TUV Rheinland Greater China employs approximately 3,800 people. Services include industrial and energy services, electrical and electronic product testing, and communications testing. Consumer products testing, ergonomics assessment, transportation services, rail system security, green product certification, Rheinland College and life care and management system, and other inspection and certification services, are ISO9001 and other hundreds of international certification organizations.TUV will be based on anti-blue light detection standards Detects cool blue anti-glare eye TVs and provides certificates.)

Cool open A3 not only protects the child's eyes, but also has a more efficient and convenient cool open wizard 2.0 artificial intelligence voice function, children's intelligence mode, a large number of high-quality children's content, providing children with a rich and colorful choice to open the door to a curious world. From the configuration point of view, design, quality, sound quality, performance and other aspects are also unambiguous. Slim metal body with linen front panel, HDR+MEMC image processing technology, JBL original audio, Mstar 6A938 top processing chip, have created the peak of this price segment TV configuration. How about the actual effect, take a look at our actual combat evaluation.
The optical anti-blue eye protection technology introduced the worrying situation of the eye health of the primary and secondary school students in China. The culprit is only the high-energy short-wavelength blue light released by the various screens we are inseparable from. Looking at the current anti-blue light technology on the market, such as Blu-ray anti-glare film, anti-blue eye mode, are the use of external forces to intercept the blue light, essentially does not reduce the harmful blue light, but also cause the picture distortion, yellow, long-term viewing not only If you do not achieve the effect of eye protection, it will increase the burden on your eyes.
Cool open A3 anti-Blu-ray education TV is how to solve the contradiction between anti-blue light and good picture quality, and do scientific anti-blue light it? Let's take a simple science and take a deeper look at Blu-ray.
Most of the various display devices that we usually use are LED-based, and now LED bulbs are also very popular. White LEDs need to be turned white by blue LED+phosphor. The more color temperature the blue LED emits, the higher the color temperature will be, and the brighter it feels. Therefore, some display devices need to be able to save power by “looking bright”. And the cost, cold light LED has become the best choice.
Why does blue light look bright and dazzling? Because its spectrum is concentrated in the 400-480 nanometer range, the wavelength is short in the high frequency band, the energy is high, the penetrating ability is strong, we know that the ultraviolet wavelength is lower than 400 nanometers. In the LED white light spectrum, there is a protruding energy peak near 450 nm. The blue light of middle and low frequencies can penetrate the crystal to the retina, and the high-frequency blue light can reach the cornea more directly. So long time staring at the screen will appear fatigue, dryness, tingling and other symptoms, is a signal of eye self-protection.
A cell on our retina is very sensitive to blue light. If it comes in contact with a large amount of blue light, it will be like the brain's signal that it is now daytime (there are also a lot of blue light in the solar spectrum). Therefore, it is very difficult to fall asleep when you take a mobile phone brush for a long time. 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.
Understand the conditions of harmful blue light, you can prescribe the right medicine. Kukai started research and development with the Optoelectronic Component Materials Laboratory of the University of California, USA, to create anti-blue light beads to solve the blue light problem from the light source. At the same time, spectrally translating is used to convert the 450nm harmful high energy shortwave blue light into 460nm harmless longwave blue light. Not only does it prevent harmful blue light, it also does not affect the blue light to emit normal colors.
Anti-Blu-ray effect measured how can we verify cool open A3 anti-Blu-ray features? Kukai has prepared a detection device specifically for us, similar to a lens tube, with a special filter in the middle, which 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.
The first set of proofs is a blue-green peacock opening screen, which can clearly see the obvious strong glare of blue light projected on ordinary LCD TVs, and the cool open A3 anti-Blu-ray education TV is very accurate to restore the blue With green, blue light is effectively avoided while ensuring the accuracy of color reproduction.
The second set of proofs is a night view of the city. Ordinary LCD TVs are almost completely enveloped by blue optical fibers. Cool open A3 only has a slight blue tendency toward the sky. The blue light wave emitted by the Cool Open A3 Anti-Blu-ray Education TV is indeed much lower than the ordinary LCD TV. It can play a good role in protecting the blue light and protect the eyes of the family.
