During the winter and summer vacations each year, you are busy with your work and carelessly take care of your children. The safety problem of choosing a free-range play is very prominent. Confinement also becomes the ultimate safe way for many parents. However, if you want your baby to stay at home with peace of mind, you only need to turn on the TV and switch to the children's channel. This leads to the winter and summer vacations as the peak season for children. According to official statistics, the number of myopia in our country has approached 450 million, of which pupils’ myopia rate is as high as 46%. Therefore, many children's protection vision products, such as anti-Blu-ray glasses and anti-Blu-ray protective film, were born, but they could not completely eradicate myopia. Children’s dependence on electronic products such as TVs, mobile phones, computers, and flat panels was still serious and they were closely attached each day. The screen will lead to a serious drop in vision, which is the root cause of the increasing number of small glasses. Compared with mobile phones, computers, and flat-panel TVs, it is considered to be less harmful to vision, and TVs that have the ability to protect vision and have massive educational resources are no better. This article's Cool Blu-ray Educational TV is a product tailored to children's issues.
Skyworth TV is very familiar with everyone, but we all think that Cool TV is a brand new TV maker. In fact, the two are inextricably linked. Skyworth's Internet sub-brand is Cool. This article's cool open anti-Blu-ray education TV main anti-Blu-ray concept, hardware includes: 4K eye protection screen, artificial intelligence voice, Huawei Hass 30 core 64-bit A73 architecture processor.
What is Blu-ray? Why should I avoid it? How to avoid?
Blue light (high-energy short-wave blue light) is a relatively high-energy light with a wavelength between 400 nm and 480 nm, and electronic screens such as mobile phones, computers, flat panels, and televisions all release high-energy short-wave blue light. The blue light waves have a very short energy and can penetrate. The lens reaches directly to the retina.
When it comes to television, most TVs currently use LED lighting. White LEDs need to be turned white by blue LED+phosphor. Therefore, the more color temperature of blue light is, the higher the color temperature is, and the brighter it is. The blue light is concentrated between 400-480 nm. The wavelength is short in the high frequency band, the energy is high, the penetration ability is strong, and the ultraviolet wavelength is lower than 400 nanometers, so the penetrating power is stronger. LED white light has a protruding energy peak near 450nm. The blue light of medium and low frequency penetrates the crystal and reaches the retina. The retina will generate free radicals, which will lead to the decline of the retinal pigment epithelial cells, resulting in visual impairment.
In response to the above-mentioned principle problems, cool open anti-Blu-ray education TV adopts spectral translation method to convert 450nm harmful high-energy shortwave blue light into 460nm harmless longwave blue light. The blue light has grown longer. Although it is still blue, it does not hurt the eyes.

Image quality and anti-blue light
Cool open anti-Blu-ray education TV screen with a resolution of 3840*2160 true 4K screen, the largest visual size 126CM, eye protection anti-Blu-ray technology. Measuring the quality of a television is not only about parameters, but also about clarity, dynamics, and color.
Like to look at documentary sceneries, body art, the definition is very important, fine to see the lines of the leaves, facial pores.
Like playing games, watching sports games, the screen's dynamic is very important, because the bad dynamic screen will produce a smear, playing the game will feel the screen is not smooth enough, smooth, there is a kind of falling frame feeling.
Like to watch movies, the color is very important, the fullness of the color determines the quality of the picture, the red enthusiasm, the melancholy of the blue, the darkness of the dark, must be the colors revealed by thousands of miles of clouds and sunny world. It is not the color of the pale world like the fog.
The word resolution is also familiar to everyone. Specifically, the resolution refers to the number of pixels on the screen. For example, 1080p means that there are 1920 pixels in the horizontal direction and 1080 pixels in the vertical direction. The cool open anti-Blu-ray education TV uses 4K pixels, it is 3840*2160, the higher the resolution, the more detailed and delicate the display effect.
The 4K picture is used for the display effect test. The blue arrow is full HD, the red arrow is 4K HD, and the cool blue anti-Blu-ray education TV is very clear in the blue arrow area or in the red area. The side proved to be cool and anti-Blu-ray educational TVs performed satisfactorily in terms of resolution.
In the color distribution, it is mainly divided into two major blocks: chromosphere and RGBYCM. Cool-opening anti-Blu-ray education televisions have regular triangles in the six regions of RGBYCM, and the colors are excessively smooth and natural. The cool open anti-Blu-ray education TV shows over-smooth colors in the color ball, no mutation, and the overall performance in the color of the good.
The response time refers to the time required to switch between black and white. The response time determines the screen dynamics. From the early 25ms to the present 8ms and 4ms, if the response speed of a 4K TV is 4ms, the color response time will be Achieve 16ms.
Refresh frequency: China's TV signal format is PAL (50Hz), foreign TV signal format is NTSC (60Hz), earlier years of display TV, refresh the low-frequency image is easy to flicker, jitter, look long time the eyes will be sore. Currently 200Hz, 240Hz is the top level, such as the Sharp LCD-60UE20A, Sony KDL-55NX810 has been discontinued. 4x speed (50HzX4, 60HzX4) for the end of the sports game to change the effect is very good.
The test used 20GB European Cup France against Germany's 4K video, you can see through the video, cool open anti-Blu-ray education TV in the dynamic processing of sports games does not appear smear phenomenon, the main video is smooth, natural colors, the overall clarity It is also very high.

Especially when the characters and background colors are greatly different, it is a test of the screen level. , cool open anti-Blu-ray education TV in the color to restore accurate, not over-rendered and not in place color straightforward.
The main selling point of Cool Blu-ray Education TV is anti-blue light, so this part uses the original image and screen shot to compare the changes of the original picture quality.

The dark blue light will become a little lighter. If you do not compare carefully, you can hardly find both with the naked eye. The difference.

Screen shot:
The cool-opening anti-Blu-ray education television is somewhat cool on the restoration of other colors such as white. It looks more transparent and clean, but it is limited to white and it has no influence on other colors.
HiFi sound quality
Compared to other HIFI configuration speakers used in cool TV models, CoolBrain Education TV does not use Taichang's custom speakers, but I have higher requirements for sound quality, so I thought that it would become my own to set up a home theater system. Think, cool open anti-Blu-ray education TV using Dolby sound + DTS two speakers, for watching movies and listening to music have a certain degree of improvement.
Dolby Dolby Sound:
Dolby Sound is a plus and minus French noise reduction boost audio method. Dolby Pro Logic surround sound makes the audio sound played more stereo surround. Combine four-channel stereo sound into two channels by recording with specific coding means. The original left channel (L), right channel (R), center channel (C), surround channel (S) The four signals are encoded into LT and RT composite two-channel signals, giving people an immersive feel in home theater.
DTS:
DTS is called the Digital Theater Sound System. The English language is called the Digital Theater System. It is one of the multi-channel audio formats. It is also very interesting to talk about. DTS and Dolby each other as the main competitors, and cool to open the Blu-ray education TV. Both of these sound effects are configured, and one mountain must not become a peaceful coexistence.
The DTS's change in sound quality is mainly a sound more encompassing, and it has crisper high frequencies and rich low frequencies compared to Dolby sound, providing an immersive surround experience. DTS’s reputation has also come from the formal adoption of “Jurassic Park†directed by Steven Spielberg in 1993.
Difference between DTS and Dolby Digital:
DTS and Dolby Digital sound processing system is completely different, DTS sound quality requirements than the storage space is important, DTS audio using 24 bits encoding, Dolby Digital only 18 bits encoding, so the audio data takes up too much space, about Du More than 3 times the number. Dolby Digital stores audio data between the perforations of the movie film. Because of space limitations, the signal is compressed and it becomes destructive. DTS is to store the audio data in another CD-ROM and synchronize with the video data. Shadows and sounds are stored in two separate spaces.
Cool Anti-Blu-ray Education TV comes with speakers:
CoolBlu-ray Education TV uses its own speakers to play movies and music. The performance of its voice is basically at the same level as the sound of other TV brands. The sound is still not at the level of home theater. Compared with its own Sony 60w600B, it is cool. The overall sound of the educational Blu-ray education TV is bright and transparent, but the sense of low-frequency volume does not feel much. When watching movies, especially when the low-frequency contrast atmosphere is needed, it feels a little weaker. Compared to the Sony 60w600B, the CoolBreak Anti-Blu-ray Education TV is on the upper side, and the high-frequency texture, brightness, and extension are better.
The two high-frequency contrasts take the violin as an example. The overall sound of 60w600B is dark and dry, and it has a lot of sensation in sound. The brightness and extension of cool anti-Blu-ray education TV are slightly better. In terms of midrange frequency, the cool opening and anti-Blu-ray education TV vocals have a moderate sense of position and the texture and thickness of the vocals are better. Low-frequency 60w600B uses alcohol sound technology, slightly better momentum. In terms of resolving power, the difference between the two's details in terms of resilience and richness is small, and it is basically the same.
Dolby Dolby audio output to the innovative X7+XM7 audio system:
Many users are dissatisfied with the sound of the TV's own speakers and will set up a home theater system externally. When it comes to setting up a home theater, it is a learning experience. I chose the innovative X7+XM7 audio system. The biggest advantage of this system is its expansion. The sex is very strong, and its own sound quality is also very good, and built-in Dolby Dolby sound, can play a good cool to open Blu-ray education TV comes with Dolby Dolby sound.
Cool open anti-Blu-ray education TV external X7 + XM7 audio system, open Dolby Dolby audio sound texture has been significantly improved, like a fat man into a muscle man after fitness, and then the biggest change is the sound field is more open, more Surround sound, rather than the sound of the flat speakers emitted by the built-in, external X7 + XM7 audio system to watch the film there is a sense of presence in the cinema, aircraft cannons sound more immersive feeling. In terms of resolving power and sound field, the X7+XM7 audio system is richer in detail when playing music. Turning on Dolby sound personally feels more suitable for watching movies.
DTS audio output to the innovative X7+XM7 audio system:
Cool open anti-Blu-ray education television with innovative X7 + XM7 audio system to switch to DTS mode, personal feel more suitable for use in music and music, vocal full of emotions, rather than Dolby sound hair paste dark, The low-frequency elastic texture is excellent, not the amount of Dolby sound effects scattered, high-frequency transparent, very suitable for string performance, especially the performance of the violin is very transparent texture.
Cool-Blu-ray educational TVs are used daily. Movies, music, and news programs are all involved. If you emphasize dialogue and playback of vocals, individuals will use DTS audio output to the innovative X7+XM7 audio system. If you watch movies, Dolby Dolby audio output to the innovative X7+XM7 audio system can be very good at the atmosphere.
Cool open anti-Blu-ray education TV In the ordinary consumer-grade TV range, the sound is quite satisfactory, and there is a gap with the HiFi-class home theater. If there is a pursuit for sound, it is recommended to use the HIFI audio system later.
