Foreword
During winter and summer breaks, many parents find themselves occupied with work and inadvertently neglecting their children's supervision. Choosing a safe environment for kids to play freely becomes particularly challenging. As a result, confining them indoors often seems like the safest option. However, if you wish to keep your child entertained at home without worry, simply turning on the TV and switching to a children’s channel might suffice. This is why the winter and summer holidays are peak seasons for children’s TV usage. Statistics reveal that nearly 450 million people in our country suffer from myopia, with a staggering 46% of school-aged children affected. Consequently, various vision protection products for children, such as anti-Blue Ray glasses and protective films, have emerged. Despite these efforts, myopia rates continue to rise. Children's heavy reliance on electronic devices like TVs, smartphones, computers, and tablets remains a significant issue. These screens contribute to a sharp decline in vision, leading to an increase in the number of children wearing glasses. Compared to smaller screens, TVs are generally perceived as less harmful to vision due to their larger size and potential educational value. However, even TVs equipped with vision protection features and extensive educational resources aren't entirely foolproof. This brings us to the Cool Blu-ray Educational TV, a product specifically designed to address children's vision and entertainment needs.
Skyworth TV is a household name, but many may not realize that Cool TV is actually an internet sub-brand of Skyworth. The two are deeply interconnected. Cool TV's "cool open anti-Blue Ray education TV" emphasizes its anti-Blue Ray concept. Its hardware includes a 4K eye protection screen, artificial intelligence voice control, and a Huawei Hisilicon 30-core 64-bit A73 architecture processor.
What is Blue Ray? Why should you avoid it? And how can you avoid it?
Blue light (high-energy short-wave blue light) refers to light with wavelengths between 400 nm and 480 nm, and it is emitted by electronic screens like mobile phones, computers, flat panels, and TVs. These short-wave blue lights have high energy and can penetrate the lens, reaching the retina directly.
When it comes to televisions, most modern TVs utilize LED lighting. White LEDs are produced by combining blue LEDs with phosphors. Thus, the higher the color temperature, the brighter the light, and the more concentrated the blue light becomes between 400-480 nm. With wavelengths in the high-frequency band, blue light has high energy, strong penetration, and lower ultraviolet wavelengths, making it more penetrating than UV rays. LED white light exhibits a distinct energy peak around 450nm. Medium and low-frequency blue light penetrates the lens and reaches the retina, generating free radicals that damage retinal pigment epithelial cells, leading to vision impairment.
In response to these issues, Cool's anti-Blue Ray educational TV employs a spectral translation method to convert 450nm harmful high-energy shortwave blue light into 460nm harmless longwave blue light. While still blue, it no longer poses harm to the eyes.
Unboxing & Appearance Details
The Cool anti-Blue Ray educational TV features the slogan "optical anti-blue light, eye-protecting eyes" on its top. It reminds me of a detergent commercial with its catchy rhyme and trendy appeal.

Image Quality and Anti-Blue Light
The Cool open anti-Blue Ray educational TV boasts a true 4K screen resolution of 3840*2160, offering the largest visual size of 126CM with eye protection anti-Blue Ray technology. Measuring the quality of a television goes beyond parameters, considering clarity, dynamics, and color.
For those who enjoy documentaries and nature scenes, the definition is crucial, allowing one to see the fine details of leaves and facial pores.
For gamers and sports enthusiasts, screen dynamics are essential, as poor dynamics can cause smearing, making the screen feel less smooth and creating a lagging sensation.
For movie lovers, color is paramount, as the richness of colors determines the quality of the picture. Reds should convey passion, blues evoke melancholy, and dark tones must reveal the depth of a thousand-mile landscape.
The term resolution is familiar to everyone. Specifically, resolution refers to the number of pixels on the screen. For instance, 1080p means there are 1920 pixels horizontally and 1080 vertically. The Cool open anti-Blue Ray educational TV uses 4K pixels, which are 3840*2160. The higher the resolution, the more detailed and delicate the display effect.
The 4K picture quality test shows the blue arrow representing full HD, the red arrow representing 4K HD, and the Cool Blue anti-Blue Ray educational TV performs excellently in both areas. The results prove that the Cool and anti-Blue Ray educational TVs deliver satisfactory performance in terms of resolution.
In terms of color distribution, the Cool opening anti-Blue Ray educational TVs exhibit regular triangles in the six regions of RGBYCM, ensuring smooth and natural colors. The Cool opening anti-Blue Ray educational TV displays overly smooth colors in the color ball, with no mutations, showcasing excellent overall color performance.
The response time refers to the time required to switch between black and white, determining screen dynamics. From early 25ms to the current 8ms and 4ms, if the response speed of a 4K TV is 4ms, the color response time will achieve 16ms.
Refresh frequency: China's TV signal format is PAL (50Hz), while foreign formats are NTSC (60Hz). Earlier TVs with low-frequency images were prone to flickering and jitter, causing eye strain over time. Currently, 200Hz and 240Hz are top-tier, such as the discontinued Sharp LCD-60UE20A and Sony KDL-55NX810. Fourfold speed (50HzX4, 60HzX4) enhances the effect of sports games significantly.
The test used a 20GB European Cup France vs Germany 4K video. Through the video, it's evident that the Cool open anti-Blue Ray educational TV does not exhibit any smearing during sports game dynamics, maintaining smoothness and natural colors. The overall clarity is also very high, providing an enjoyable viewing experience for all sports fans.
The video is more intuitive:
In terms of color reproduction, the main characters and scenery are prominent. The Cool opening anti-Blue Ray educational TV displays very full colors, with smooth and natural hues. Particularly when characters and backgrounds differ greatly, it tests the screen's capabilities. The Cool opening anti-Blue Ray educational TV accurately restores colors without over-rendering or dulling them.
The main selling point of Cool Blu-ray Education TV is its anti-blue light feature, so this section compares the changes in original picture quality using the original image and screen shots.

The Cool opening anti-Blue Ray educational TV appears somewhat cooler in restoring other colors like white, looking more transparent and clean. However, this effect is limited to white and doesn't influence other colors.
HiFi Sound Quality
Compared to other HIFI-configured speakers used in Cool TV models, the Cool Brain Education TV doesn't employ Taichang's custom speakers. Instead, it places higher demands on sound quality, suggesting it might be better suited for setting up a home theater system. The Cool open anti-Blue Ray educational TV uses Dolby sound + DTS dual speakers, improving the experience for watching movies and listening to music.
Dolby Dolby Sound:
Dolby Sound is a French noise reduction boost audio method. Dolby Pro Logic surround sound creates a more stereophonic and immersive audio experience. It combines four-channel stereo sound into two channels using specific coding methods. The original left (L), right (R), center (C), and surround (S) channels are encoded into composite two-channel signals (LT and RT), giving viewers an immersive feel in home theaters.
DTS:
DTS is known as the Digital Theater Sound System. It is one of the multi-channel audio formats and an interesting topic. DTS and Dolby are main competitors, and the Cool open Blu-ray education TV is equipped with both, ensuring peaceful coexistence.
The main difference in DTS sound quality lies in its more encompassing sound, with crisper high frequencies and richer low frequencies compared to Dolby sound, providing an immersive surround experience. DTS's reputation stems from its formal adoption in Steven Spielberg's 1993 film "Jurassic Park."
Difference Between DTS and Dolby Digital:
DTS and Dolby Digital sound processing systems are entirely different. DTS places greater importance on sound quality storage space, using 24-bit encoding, whereas Dolby Digital uses only 18-bit encoding. Thus, DTS audio occupies more space, approximately three times more than Dolby Digital. Dolby Digital stores audio data between the perforations of movie film, compressing the signal due to space limitations, which can be destructive. DTS stores audio data on another CD-ROM, synchronizing it with video data, storing shadows and sounds in separate spaces.
Cool Anti-Blue Ray Education TV Comes with Speakers:
The Cool Blu-ray Education TV uses its own speakers to play movies and music. The performance of its voice is comparable to other TV brands, but it still falls short of the level of a home theater. Compared to its own Sony 60w600B, the Cool Break Anti-Blue Ray Education TV offers a bright and transparent sound overall, but the sense of low-frequency volume is lacking. Watching movies, especially those requiring a low-frequency atmospheric contrast, feels slightly weak. In comparison to the Sony 60w600B, the Cool Break Anti-Blue Ray Education TV performs better in terms of high-frequency texture, brightness, and extension.
The two high-frequency contrasts take the violin as an example. The overall sound of 60w600B is dark and dry, with a lot of sensation in sound. The brightness and extension of the Cool anti-Blue Ray education TV are slightly better. In terms of midrange frequency, the Cool opening and anti-Blue Ray education TV vocals have a moderate sense of position, with better texture and thickness of the vocals. The low-frequency 60w600B uses alcohol sound technology, providing slightly better momentum. In terms of resolving power, the details of the two's resilience and richness are similar, essentially 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 opt for an external home theater system. Setting up a home theater is an educational experience. I chose the innovative X7+XM7 audio system. The biggest advantage of this system is its strong expandability, and its own sound quality is also very good, with built-in Dolby Dolby sound, capable of playing the Dolby Dolby sound that comes with the Cool open Blu-ray education TV.
Cool open anti-Blue Ray education TV external X7 + XM7 audio system, Dolby Dolby audio sound texture has been significantly improved, like a fat man becoming a muscular man after fitness, and the biggest change is the sound field becoming more open, more surrounding sound, rather than the flat speaker sound emitted by the built-in, external X7 + XM7 audio system gives a sense of presence when watching movies, with more immersive feelings from the sound of aircraft cannons. 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-Blue Ray education TV with innovative X7 + XM7 audio system, switching to DTS mode, personally feel more suitable for use in music and singing, the voice is full of emotion, rather than Dolby sound's hair paste dark, the low-frequency elastic texture is excellent, not the scattered Dolby sound effects, high-frequency transparent, very suitable for string performances, especially the performance of the violin is very transparent texture.
Cool-Blue Ray educational TVs are used daily, involving movies, music, and news programs. If you emphasize dialogue and vocal playback, 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 create a great atmosphere.
Cool open anti-Blue Ray education TV, in the ordinary consumer-grade TV range, the sound is quite satisfactory, 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.
Cool Open OS 6.0 System
The Cool Blu-ray Education TV is equipped with Cool OS 6.0. The left navigation is divided into: My, Featured, Shopping, Children, and Apps. In the My section, selecting the child mode will enter the child viewing mode. This mode is suitable for children. To exit the child mode, verification is required.
