Cool open TV A55 flagship disassemble evaluation internal hardware dismantling
Cool open TV A55 flagship disassemble evaluation
In the previous evaluation, the CoolOpen A55 had a good performance both in terms of content performance and device interaction. What would be the quality of the internal workmanship of the Cool A55? Today, the Coolopen A55 will be further dismantled and analyzed.
The ordinary black cover is certainly a lot of people to see, compared to the cool open back cover is still very beautiful, the back cover is fixed by 20 screws, the machine's only power button is also in the back cover.
Remove the base, remove the rear cover screws, remove all the fixing screws, and only need to use the card to open the rear cover and the body's buckle, and you can see the internal structure of the entire TV.
After the dismantling, we found that the structure inside the TV was very simple, with highly integrated modules and a clear internal structure to ensure the stability experience for users, while modularity was able to add new content at any time. A highly integrated modular product often means that the technology of the product is already quite mature, and there is a very good experience whether it is used or expanded in the later period.
After identification, we can easily see the TV's power module, screen backlight module, intelligent system module, input expansion module, Bluetooth module, WIFI module and screen module.
The main smart module is removed first. The smart processor board has several points worth noting. The first PCB board is followed by the capacitor. To know that the PCB board is the most basic part of all products, we can see that the cool open trial is a blue PCB, although the color can not directly determine the quality of the PCB. However, the tough plate can still be reflected from the touch.
In addition to plates, the use of solid capacitors has now become an important measure of the quality of a product. Cool open using solid capacitors, while ensuring performance while also reducing the size, but also with the traditional electrolytic capacitors filled with electrolytes, solid capacitors used solid materials, the temperature sensitivity is not high, will not produce burst, The dangers of leakage and other hazards are even more outstanding in terms of high and low temperature and performance.
The heat sink on the motherboard is a PCB board that is directly soldered. If it cannot be uncovered, it will not be able to see the true capabilities of Huawei Hisil's Hi3751 12-core. According to Cool Open, the A55 flagship is the most powerful TV chip on the market. Combining the lightweight optimization technology of Linux with Coocaa's lightweight system, the A55 is faster and faster than ordinary Internet TV in daily startup, response, high-definition video, and large-scale game applications.
In addition to smart modules, it is of utmost importance for the television to have a constant current. The power module plays such a role. The power supply is accessed from the lower left standard interface, and through a series of complicated processes such as rectification, filtering, frequency conversion, and voltage regulation, the voltage and current required by the lower-level circuit are finally obtained.
Recall that the backlight driver circuit module, the main role of the module is to provide a constant current and constant voltage power supply for the LED backlight source in the display screen. It is reported that LED light emitting diode light source, unlike the traditional light source, is a non-linear component. The function of this circuit is to dynamically adjust the power supply state so that the current tends to be constant.
Here the input module, Bluetooth module, WIFI module, input module supports AV input, HDMl input, network cable support, USB, debug port. The Bluetooth module supports Bluetooth Low Energy 4.0. The WIFI module supports both 2.4G and 5G formats.
In fact, you can see from the beginning of the A55 ultra-thin fuselage which accommodates two small black sound chambers, each sound chamber in addition to the bottom of the tweeter, but also equipped with a large stroke bass speaker. In the back of the sound cavity is covered with a large area of ​​sponge layer, responsible for absorbing speaker vibration, so that the sound is more pure.
In general, the Cool A55 adopts a good hardware configuration. The manufacturing process relies on Skyworth's more than ten years of accumulation and it is also very good. The concept of integrated modularization has also been verified during disassembly. A good product has no backside, and now there is no even inside.
