What are the ideas for the selection of TV products? The first time set the selected size, and then to the store to see the real effect, this purchase step is believed to be most suitable for most users. For a 50-inch TV product, the price range ranges from a thousand yuan to a million yuan. How much do you know about some ignored parameters? May wish to talk through Cool Open 50A2.
Appearance design: metal thin body details work excellent
The development direction of TV manufacturers is actually more than everyone thinks. There are Internet-oriented eco-systems, there are specialized panel technologies, and there are also entry-level products that are actively developing cost-effective. On May 24, Kukai officially launched the cool-open 50A2 smart TV with HIFI and big content on the “non-ecological big content†strategy conference. The 4K resolution product with a price of 3499 yuan was used. What is the advantage?
At present, the 48-55-inch products in the TV market are gradually becoming the mainstream. They neither bid farewell to the era of small screens nor bring burden to the average family living room. The control distance between 2 meters and 2.4 meters is most suitable for the Chinese market. Cool open 50A2 is such a product, 50-inch screen positioning, the introduction of the latest 4K resolution technology, on the face of data enough to attract enough to satisfy consumers. The body uses a high proportion of metal material, the front panel strip hole design makes it look no longer monotonous, but also conducive to the heat treatment of the TV in the work process.
There are many stand frame styles, there are T-type, Z-type, and the entire base of the cloud base, cool open to choose a more secure V-type tripod. However, a large number of facts prove that as long as the fixtures that can be applied to television products have basically sufficient stability and security, everyone does not need to be overly entangled.
Coocaa 50A2 has two symmetric JBL stereos on the back, which are very eye-catching. The bass radiator designed by Cooge and Harman creatively appears on TV products, and enhances the bass effect through air movement and front and rear radiators. A technology only appears in the JBL audio above $1,000. In addition to external power amplifiers, the 50A2 also uses the TASS5766 professional HiFi power amplifier chip and supports DTS 2.0 technology.
Incidentally, this time about the route of “HIFI TVâ€, with the increase of quality of life, many families choose to provide more professional HIFI audio equipment for the living room, and these devices are often placed near the TV cabinet. However, this does not mean that the HIFI audio system will serve the TV because the latter has limited thrust on the music. In the end, more people will give up and then use the power amplifier equipment for TV products. It follows that choosing a television with excellent amplifier effects will be a matter of time and time again.
Interface, Cool open 50A2 configuration is also very rich, higher standard HDMI 2.0 interface three, USB 3.0 interface two, Ethernet interface, there are hidden TF card slot, scalability enough to meet the smart device Use it for connection.
The frame part is made of melanin plastic material frame, and the surface has a metal stamping, 9mm frame width and 9.9mm thickness of the fuselage combined, the overall sense of the body of science and technology done relatively in place.
In the final part of the remote control, this time the Cool Open 50A2 did not include children's remote control as standard, and its remote control was relatively simple. Maintaining a consistently sleek and compact appearance, the buttons have a small area and the press feel is crisp and comfortable. In addition, the power supply is changed from the button battery to a more convenient seventh battery.
Display effect: talk about 4K from the perspective of ordinary users
Relatively some users currently do not accept 4K products. Their reason is often because there are not many 4K video resources. However, I believe that 4K resolution TVs are just like cars that are progressing from manual to automatic transmissions. They are all a leap forward new generation of products. Of course, the display effect can be said to be the most decisive factor in determining the quality of a TV set. It can be said that the panel occupies the maximum cost of a TV product, and there is definitely a different performance without using a price. As a consumer, it is only necessary to find the best one at the same price level of the budget.
Given the professional data obtained by some other organizations, the NTSC color gamut of the Cool Open 50A2 reached 79.28% (this standard is already consistent with that of Apple MacBook computers). The brightness of each region is even and the performance meets or exceeds the price of 3,000 yuan.
In terms of function, because the panel resolution reaches the true 4K standard of 3840x2160, the addition of 4K resolution to the mode selection is not only a sense of superiority, but also a real visual enhancement.
First, the screen performance picture under a common angle may cause sensory differences due to the camera's white balance and other qualities. The author has made a few adjustments later to seek closer results to the naked eye. Cool open 50A2 uses RGB three-primary pixel panel, which does not add too many new technologies.
The above pictures are shots of cool shots of 50A2 playback 4K video. It can be seen that the exquisite sense, realism and layering brought by 4K resolution are absolutely not reachable by ordinary televisions. As the size of TV panels increases, the resolution and PPI data become more important. Under the same 50-inch premise, the FPI's PPI is 44 and the 4K products reach 88, which is a significant gap.
Among the measured pictures above, you can see that the details of the screen performance and tension are very strong, color reproduction and color transition capability is accurate, the overall performance is very good. If we look strictly at the point of view, the color edge transition details in the picture will have a certain color expansion and the performance capability will decline. In addition, although Coocaa 50A2 does not support HDR processing by hardware, it incorporates a unique software layer HDR quality optimization technology. Brightness and darkness are balanced by software technology, and the picture is closer to reality.
In addition to the conventional color performance, there are actually more parameters to be concerned about television products. Often these parameters cannot be seen from the short-term visual observation, but when faced with different scenarios, many problems will arise. Among these two pictures, it can be clearly seen that the large-area white color of Fig. 1 is still quite uniform and there are no vignetting problems in all four corners; "To be completely black" means that there is no light leakage problem.
In addition to this indicator, there is also a dynamic performance. The so-called response time is the time from bright to dark or from dark to light. The direct influence of this parameter is what we call the concept of “there is no picture smearingâ€. Of course, smear may appear to be behind now, and ultimate fluency is the current standard. Most manufacturers are more taboo on this parameter, because many products on the market dynamic response time is long, high-definition movies, sports live experience has a great impact. Cool open 50A2 screen response time for the industry's higher 9ms, with MEMC frequency multiplication technology, measured fluency will allow everyone to have a feeling of transition from ordinary home TV to a movie theater. Eliminating jitter tailings eliminates fatigue and plays an important role in children’s vision protection.
System Interaction: Even TVs are homogenized
The mobile phone industry has long advocated the concept of homogenization. In fact, TV systems based on Android have also faced the same problem. Fortunately, everyone's dependence on television systems is much lower than that of mobile phones. We only need "functionality" rather than absolute "experience."
On the interface of experience, Coolopen 50A2 inherits its own system style. It is simple and convenient. It is the focus of television product system development. The lower learning cost is also beneficial to the use of elderly or children in the living room.
The operating logic of this system is also relatively simple. Although it is also based on Android development, CoolOpen simplifies many redundant system setup items and develops functions for TV products such as timing shutdown and default signal source selection. Press and hold the remote control home button to open the background management and perform a one-click acceleration to clear the memory. These grounding gas and humane options, domestic manufacturers far better than several international big names.
With the strong monitoring of a certain department, the number and scalability of APPs in TV systems have been declining. Friends who need more third-party functions need to use their own hands. This is not described in detail here. However, in the new function, the author discovered the smart device control center, which can remotely operate smart products in the same local area network. It seems that Cool Open intends to develop its television product into the control center of the home smart terminal, which has both ideas and convenient life.
There are good hardware and display effects, of course, with a rich content resources, the combination of software and hardware can play the greatest value of a TV. In terms of content, it is recommended to install a sofa butler - the sofa butler is a third-party app store designed specifically for smart TVs, Android box users, carefully providing television, box users with high-quality television exclusive version of the application, including with live Or on-demand video and audio and video software, various types of recreational competitive video game software and daily office entertainment management system management tools. Cool open 50A2 TV users can refer to the tutorial: Cool open TV 50A2 installation method Install sofa butler to expand third-party applications.
Recreational resources: the scope involved is wider
In addition to the above-mentioned priorities, the purchase of a TV set now requires the support of its Internet eco-resources. Here, Sony Dafa, Samsung Dafa and other big manufacturers can ignore the solid users, after all, these users in order to feel a Huada TV is enough. Cool open 50A2 comes with two years of love Qiyi TV members, grounding gas experience more complete.
As a manufacturer with long-term TV production experience, its online video resources are very strong with each company's relationship, which is also an important guarantee for the user's resource security as a TV brand. According to the current policy, there will be a rigid lag in film resources for movie theaters, but the play of television dramas will follow the thread.
The scope of Kukai's involvement in the provision of resources is very wide, including video, software, music, and even books. The overall classification of resources is still clear, but since the two-year iQiyi TV membership is included, most of our operating space will go deeper here.
The difference between the self-contained search interface and previous versions is insignificant, and depending on the operation of the remote controller, it may be tedious. If there is a condition, individuals are advised to keep a set of mouse buttons for the smart TV at home. As the main 4K picture quality of Coolopen 50A2, the 4K video resources it can enjoy are still relatively limited, but as an early adopter experience is still very powerful.
After testing, it was discovered that Kukai Kaiyuan did not provide local music resources, and music support still needed to rely on third parties. However, Coocaa 50A2 offers music playback mode, can fully play JBL custom bass performance and performance.
Extended features: Children's model innovation
The last part of the children's model appeared as early as the cool open A series, the difference is that the 50A2 does not match the children's remote control, requiring the user to purchase extra.
The emergence of the children's model is actually quite necessary. Faced with various types of content that cannot be distinguished in the Internet environment, there are too many resources that are unsuitable for children or children with malaise. How to prevent children from infringing upon bad information is actually a matter of enlightenment. Has an important influence.
The barrier to entry into parental control is relatively low. A simple multiplication calculation can be seen in the children's model for children under the age of five, but for children of this age group, the operating logic of this child mode is still somewhat complicated.
The layout of the child mode is actually relatively simple, and the operation logic is not too complicated, but after entering the secondary menu, the entire interface seems to be relatively dense, and there are many involving member login operations and resources, application download functions, operations The difficulty is still high.
Game performance: hardware parameters are sufficient
Adopt 64-bit A72 architecture + A53 architecture MSTAR 6A938 quad-core processor, 3-core Mali T820 GPU, and provide 2G DDR3 RAM + 8G eMMC 5.0 ROM, it can be said that for a TV is a top allocation, but these parameters not so important.
Although Coocaa 50A2 can smoothly run 3D games on TV systems, I believe that the trend of TV games in the future is still based on mobile platforms. The use of a mobile phone as a handle and even making the mobile phone a host of video games seems to be the trend of development. Therefore, as mentioned above, these top-matching parameters are not important.
Summary: Products that are looking at perceptions at the price of 3499 yuan
There is no 3D, no surface, no fancy peripheral configuration, and the most basic and ultimate screen look and feel experience seems more in line with Coocaa 50A2 positioning. Support 4K resolution, and has a very good color performance, and there is JBL audio HiFi chip blessing, 50A2 is basically a product will not lag behind in the next few years. In terms of screen quality, there are no light leakage problems, and there are flagship-level response time and other important parameters. As for the resources, the gift of the 2 year iQIYI TV version member solved all problems at once. In general, Coocaa 50A2 is most suitable for watching TV, but also consumers who want to watch television.

Coocaa 50A2 has two symmetric JBL stereos on the back, which are very eye-catching.
