Foreword
During winter and summer breaks, parents often find themselves preoccupied with work while neglecting their children's safety and well-being. One of the most significant concerns during this period is the choice of free-range play for children, which can pose serious risks. Consequently, many parents opt for confinement as a safer alternative. However, instead of keeping your children indoors, you can simply switch on the TV to a children’s channel and let them enjoy their time safely. This makes the winter and summer holidays peak periods for children's programming. Statistics show that the number of nearsighted individuals in our country has reached nearly 450 million, with the rate of myopia among schoolchildren as high as 46%. As a result, various children's vision protection products have emerged, including anti-Blue Ray glasses and anti-Blue Ray screen protectors. While these products may help reduce eye strain, they cannot entirely prevent myopia. Children’s heavy reliance on electronic devices like TVs, mobile phones, computers, and flat screens remains a major issue, with kids spending significant amounts of time glued to screens. These screens contribute to declining vision, which has become a growing concern. Compared to mobile phones and computers, TVs are considered less harmful to vision due to their larger screens and educational resources. However, even TVs that claim to offer vision protection aren’t entirely foolproof. This article introduces the Cool Blu-Ray Educational TV, a product specifically designed to address children’s vision health.
Skyworth TV is a well-known brand, but many might not realize that Cool TV is actually its internet sub-brand. Cool TV shares the same DNA as Skyworth, focusing on innovative technologies and user-friendly designs. The Cool Open Anti-Blue Ray Educational TV boasts several advanced features, including a 4K eye protection screen, artificial intelligence voice capabilities, and a Huawei Hisilicon 30-core 64-bit A73 architecture processor.
Unboxing & Design Details
The Cool Anti-Blue Ray Educational TV features a bold slogan on its top: "Optical anti-blue light, eye-protecting eyes." This catchy phrase is reminiscent of some detergent advertisements and rhymes well with modern Chinese pop culture.
The TV has a sleek and sturdy design with an ultra-narrow gold-painted injection-molded frame, complemented by a minimalist gold base. The overall build quality is solid, with subtle branding for a refined look.
The back panel is made of ABS high-strength engineering plastic, with input and output interfaces strategically placed. On the right side of the unit, you’ll find USB 2.0, USB 3.0, video/audio inputs, and network ports. Beneath the body, there are HDMI 1, HDMI 2, and HDMI 3 ports, along with a 9V/500mA power adapter, debug port, audio output, and RF input interface.
The label on the back indicates that the TV’s rated power is 120W, which is quite efficient in terms of energy consumption. Standby power is just 0.5W, making it eco-friendly. The dual-core power cord plug features a 90°C design, enhancing usability and longevity.
The Cool Anti-Blue Ray Educational TV comes with two bases and four screws for easy assembly. Below the base, there are left and right markers to ensure proper alignment and secure attachment to the main unit.
Accessories include a power cord, remote control, two size 7 batteries, two bases, four screws, a product guide, and a warranty manual.
The remote control features an arc flat design with a matte black ABS resin surface and requires two No. 7 batteries.
Image Quality and Anti-Blue Light
The Cool Open Anti-Blue Ray Educational TV boasts a true 4K screen with a resolution of 3840x2160 pixels and a maximum viewing size of 126 cm. Its eye protection technology reduces harmful blue light exposure.
When evaluating a TV, clarity, motion handling, and color reproduction are key factors. For instance, watching documentaries or nature scenes emphasizes sharpness and detail, allowing viewers to appreciate intricate details like leaf veins or facial pores.
For gaming and sports, motion handling is crucial. Poor motion handling can lead to smearing, making games feel choppy. Watching movies, on the other hand, relies heavily on color reproduction, where vibrant hues create a lifelike experience.
Resolution refers to the number of pixels on the screen. For example, 1080p corresponds to 1920x1080 pixels. The Cool Open Anti-Blue Ray Educational TV uses 4K pixels, offering a resolution of 3840x2160, delivering finer and more detailed visuals.
The 4K screen was tested for clarity, with blue arrows indicating Full HD and red arrows showing 4K HD. The Cool Open Anti-Blue Ray Educational TV excelled in both areas, proving its superior resolution.
In terms of color accuracy, the TV displays regular triangles in the RGBYCM regions, ensuring smooth and natural color transitions. The color ball test confirmed the TV’s excellent color reproduction without any noticeable mutations.
Response time measures how quickly the screen switches between black and white, impacting motion handling. Early TVs had response times of 25ms, while modern TVs have achieved 4ms or 8ms. A 4K TV with a 4ms response time offers a color response time of 16ms.
Refresh rates vary between 50Hz (PAL) and 60Hz (NTSC). Higher refresh rates, such as 200Hz or 240Hz, provide smoother motion, particularly in sports events.
Testing with a 20GB 4K video of the European Cup match between France and Germany showed the Cool Open Anti-Blue Ray Educational TV handled motion smoothly, with no smearing and vibrant, natural colors.
Color reproduction was impressive, with the TV accurately rendering complex scenes without over-saturation or loss of detail.
The primary selling point of the Cool Blu-Ray Educational TV is its anti-blue light technology. Comparing the original image with a screenshot reveals a slight reduction in blue light intensity, with darker blues appearing slightly lighter.
Hi-Fi Sound Quality
Unlike other TVs that use custom speakers, the Cool Blu-Ray Educational TV focuses on sound quality improvements. It features Dolby Atmos and DTS audio systems, enhancing the movie-watching and music-listening experience.
Dolby Atmos creates an immersive surround sound experience, combining four-channel stereo into two channels with specific coding. This results in a more engaging home theater experience.
DTS, or Digital Theater System, is another multi-channel audio format. It offers crisper highs and richer lows compared to Dolby Atmos, creating a more immersive experience. DTS gained popularity with its use in the 1993 film "Jurassic Park."
DTS and Dolby Atmos differ in their audio processing systems. DTS requires more storage space due to its 24-bit encoding, while Dolby Atmos uses 18-bit encoding, resulting in greater compression and potential loss of quality.
The Cool Anti-Blue Ray Educational TV’s built-in speakers perform adequately, offering bright and transparent sound but lacking deep bass. For optimal sound quality, users might consider an external Hi-Fi audio system.
Cool Open OS 6.0 System
The Cool Blu-Ray Educational TV runs on the Cool Open OS 6.0 system. The left navigation menu includes options for My, Featured, Shopping, Children, and Apps. Switching to Child Mode provides a safe viewing environment tailored for children. Exiting Child Mode requires verification, making it difficult for younger children to bypass.
The content is divided into categories like movies, dramas, animations, games, music, and shopping. Resources are abundant, covering entertainment, shopping, and educational content. The platform claims to offer over 10,000 TV shows, 80,000 episodes, 120,000 animations, and 1,500 variety shows.
Child Mode features popular recommendations, cartoons, children’s films, education, and games. Popular series include "Peppa Pig," "Love Adventures," "Police Car," and "Little Ocean Column," totaling over 40,000 cartoons. Other content includes children’s variety shows, songs, educational games, and English learning resources.
Users can download various apps, turning the TV into a large-screen smartphone.
Conclusion
The Cool Blu-Ray Educational TV is a great option for children’s vision protection, featuring advanced hardware and software. With 2GB RAM and 16GB storage, DTS and Dolby Atmos audio, and specialized anti-blue light technology, it’s ideal for safeguarding children’s eyesight. The Cool Open OS 6.0 system offers extensive resources, suitable for both children’s education and adult entertainment. While the TV lacks preloaded VIP content, it remains a comprehensive and healthy smart TV option.
