Cottage chip + low-end panel? Six high-end Internet TV dismantling contrast

·Why do we have to dismantle Hengping?
This is the question that must be answered at the beginning. The reason is summarized as three points. First of all, the use of materials within a television will affect the overall quality, and the imaginary parameters will also seriously affect the consumer's rights of use. These need to be dismantled to verify the authenticity. Secondly, there are few television dismantling reviews in the industry. As the nation’s most influential science and technology media, the ***** has the responsibility to let everyone know how TV differs in its internal structure. Finally, under normal circumstances, users will not dismantle the TV on their own. This cross-assessment also aims to satisfy readers' curiosity about the internal structure of television.
· Why Internet TV?
The popularity of Internet TV has been raging for two or three years. Under the condition that the TV operating rate has been deteriorating year after year, it has solved the user's use of pain points to a certain extent, and it has also allowed some users to return to the living room. According to the results of the latest market adjustments, Internet TV's attention is still very strong and it is the biggest competitor of traditional TV brands. At the same time, Internet TV has become the preferred television category for most young people today.
Although the scenery was infinite, Internet TV was also criticized by some users. The quality of products and aftermarket became the two most concentrated issues. At this time, everyone thinks that Internet TV can be sold at a relatively low price. What does it depend on to make a profit? Will there be cases of cutting corners? Is there any ingredient that boasts of hype? With these many questions, we finally chose to dismantle the Internet TV brand.
· What are the reasons for choosing these six brands?
At present, there are more than a dozen Internet TV manufacturers, but there are not many brands that can make achievements in terms of popularity, terminal sales, and product strength. The six brands selected this time meet the current "first-line Internet TV brands. "level. They are usually the focus of users' attention and purchase, and they all have accumulated certain user groups. The six brands are CAN, Cool, Little Whale, Millet, VIDAA, PPTV.
Six major first-tier Internet TV brands CAN can still see: Internet TV brands among the rare state-owned background brands, established two years to achieve the full matrix industrial chain strategy;
· Cool open: With the concept of "playing out attitude", it captures the favor of many young users, but also backs Skyworth, with unique advantages in the industrial chain and production technology;
· Micro-whale: a well-known low-key practice, with the reasonable integration of online and offline channels and many persuasive products, has created impressive sales results;
· Xiaomi: It is currently the most popular Internet TV brand. Under the circumstance of sluggish industry, sales volume can still rise against the trend;
· VIDAA: As the brand of Internet TV branded by Hisense, ULED ace technology has achieved a strong advantage in core picture quality;
·PPTV: Deeply cultivating content for 12 years, capturing many sports event resources, and relying on Suning's powerful sales channels, has become the first choice for sports fans.
Since it is a horizontal assessment, we naturally have to choose the same level of products. For the six Internet TV brands, we have selected the flagship products, and the size is selected as the most mainstream 55 inches in the current market. We hope that through the horizontal comparison of the dismantling of the six flagship Internet TVs, users can intuitively understand the internal technological level of top Internet TVs, and verify whether there is any situation of cutting corners or propaganda. Therefore, the parameters in the above table are for reference only, and they must be disassembled for inspection.
· "Love at first sight" Who is more adorable to six TVs?
Before entering the dismantling, we first consider the appearance design of the six TVs. Usually 55-inch TVs are basically placed in the living room, so the value is naturally very important. This section mainly focuses on the appearance, material and design of television.
Putting the six TVs together brings people different feelings. This is what we very much hope to see. Although the homogeneity of the TV industry is very serious at present, it is not easy for us to see their respective attribute labels from the six flagship products.
See still X55Q is the brand's first surface product, 4000R gold curvature is currently the most mainstream surface design. The overall color scheme uses silver + gray and black in the rear shell. This low-key color scheme also makes the entire TV look very concise. At the same time, the back panel of the TV is also made of metal. Although the design of the base that extends to the inside looks somewhat uncomfortable, we can also see the efforts made to differentiate products.
Cool open 55A3 basically continued the previous generation of design concepts, ultra-narrow frame, fabric bottom border and metal backboard are a good bonus points, while the body thickness of only 7.9mm, in this Hengping 6 There is also a big advantage in television. The modular design of the back and the all-black color look technically pleasing, but it also appears more sturdy.
As mentioned earlier, the brand of micro-whales has always been known for its low-key stability, and this concept has also continued into the design of products. Although the second generation of micro-whale TV does not seem to have a very good place, but after careful observation will find that the details of the control done very well. The bridge-like base looks soft and firm, and the metal elements of the frame and the backboard can be seen to be full of materials. This combination of softness and rigidity will only be felt after careful experience.
Millet TV 4 is a representative of its high-end products. We will see that millet high-end televisions have basically adopted such a design language. Both the TV main body and the base are black, and the back panel uses a metal wire drawing process. The ultimate 4.9mm slim is the biggest highlight of this TV, and is the thinnest of the six TVs.
VIDAA, as Hisense's high-end Internet TV brand, also interprets luxury concepts thoroughly. The TV uses champagne gold as a whole, and it also boasts a 4000R curvature, exposing its luxurious texture. The thickness of the body of the TV is only 8.9mm, although not the thinnest one among the six, but the one-piece design is still a lot of extra points. At the same time, the hollow circle at the bottom right of the TV is also a symbol of VIDAA TV.
PPTV N55 TV is the brand's transformation to high-end this year. From the TV design, we can obviously feel different from the previous products. The overall black body with gold mirror base, high-end texture immediately revealed, while the TV screen frame are used on both sides of the seamless bending process, or with aerospace grade aluminum material, the material is not muddled.
From the side, because the look design and VIDAA both use a curved surface design, they may feel bloated visually. Under the general trend of ultra-thin TVs, the performance of the six TVs is actually quite satisfactory. There are no very bulky products. However, the Xiaomi 4.9mm body has become the thinnest one.
The base can see the difference from the side at a glance. Among them, the octagonal shape, the cool whale, the PPTV, and the PPTV adopt the “eight” type footing design, among which the golden mirror base of PPTV has a higher degree of recognition. Millet TV 4 adds a touch of art to the base of an antlers. The VIDAA TV's triangular base is also more aesthetically pleasing to young people.
Part of the appearance is subjective evaluation, different people will have different preferences, so the author invited 10 colleagues to score for the six television (in appearance, material, design three dimensions), and finally get the average score. In the end, Millet TV 4 achieved the highest score with a 4.9mm ultra-thin fuselage and aesthetic design.
· The internal structure considers the details to control the following let us officially enter the dismantling process. In fact, for the dismantling of the TV, there is almost no difficulty. The internal structure of the TV can be seen by unscrewing the screws at the rear cover. However, after the author dismantled it by himself, it was suggested that everyone should not dismantle the TV without authorization. Since the LCD TV is powered off, the capacitors and coils on the power board need to have a discharge process. There will be a certain voltage during this period of time, which is very dangerous! The author is one of the victims...
In this link, we first removed the rear cover of the six TVs and the internal structure was clearly visible. There are four major parts, namely the power board, the T-CON (liquid crystal drive board), the TV main board, and the audio part. Let's take a look at the internal design of the six TVs.
To see the internal structure of the X55Q TV adopts the traditional layout mode, the power board is on both sides, and the LCD driver board is in the center. Because the X55Q uses a 2.1-channel design, there is also an independent bass cavity in the middle, and a speaker portion on both sides of the bottom. The performance of the sound quality is worth looking forward to. However, although there is enough room on the back of the TV, the size of the power board and the main board is smaller, just like the ITX mini board in the mainframe. At the same time, the overall wiring is also relatively messy and the internal design has room for optimization.
Cool open 55A3 TV also uses the traditional layout, but the internal space is slightly cramped, and the four core modules are quite close. However, Coocasure uses proper cabling and corresponding "hidden" designs to allow the core modules to work properly. This has the advantage of saving space and making the TV more slim overall.
We have always said that the micro whale has always been concerned with the details of the performance, through dismantling we further confirmed this view. The second generation of this micro-whale TV has a very neat internal structure, and the core modules are all kept at an appropriate distance. The overall wiring is the most tidy among the six TVs, thanks to a reasonable layout design. The only downside is that the bottom audio module and the remote receiver board design are slightly cramped in the same area.
Millet TV 4 in order to pursue the ultra-thin 4.9mm fuselage, in the internal space to make great optimization, although the traditional layout, but the LCD driver board is hidden in the bottom of the TV, in order to be protected And play a fixed role, millet also designed a metal protective shell. Overall, Xiaomi TV 4 is relatively simple inside, but it is not as neat as the whale in the wiring. At the same time, this TV's audio module is set in the front, only a small part of the space, the sound quality is impressive Worry.
Hisense VIDAA V1 TV has always been shown in high-end gestures in the Internet TV brand. Its layout within the TV is also relatively reasonable. Each small module has also set up enough space for the stability of the connection line. However, on the whole, there are room for optimization in some details. For example, the connection lines between the motherboard and other devices are slightly cluttered and do not do a good job of shielding and fixing.
As a product of PPTV's transition to high-end products, it can be seen that the N55 has taken a certain amount of effort in its internal structure. Although there are a lot of cable tapes attached, it guarantees the stability of each connecting line and also avoids the cross-knots of the lines. At first glance, it is somewhat cluttered but disorderly but orderly. The overall internal design is satisfactory.
I believe that through the dismantling of the rear cover of the TV, we can see that the difference in the internal structure of the LCD TV is very small. In total, only these major core components are included. Therefore, we only score 3 points for the three dimensions of internal cleanliness, space rationality, and detail processing.
TV core motherboard competition Internet TV has always had higher requirements for hardware configuration, because better hardware configuration can make TV and smart phones, tablet and other electronic devices, to provide users with a full range of intelligent services.
As the most central part of TVs, motherboards integrate many important hardware such as CPU (central processing unit), GPU (graphics processor), memory, and flash memory. Their quality will not only affect the smooth operation of the whole machine, but also The improvement of picture quality can also play a key role.
To see still X55Q motherboard is relatively small size, board module and chip clear, terminal side out, all using plug-in mode combined with the motherboard. The mainboard is equipped with an Mstar 6A938 processor, a Mali-T820 display chip, 4GB of memory, and 32GB of flash memory. The back of the motherboard is also printed with Dobly Digital Plus. The sound quality is worth looking forward to. At the same time, in order to save the area of ​​mainboard use, the core hardware is all concentrated under the black gutter type cooling module to ensure that the device can operate at normal temperature.
Cool open 55A3 TV motherboard is the largest of the six TVs, the entire board looks very clean, solid capacitors distributed in all corners of the motherboard, memory and flash memory are located around the black heat sink. The motherboard also features the Mstar 6A938 processor, but the 3GB memory and the 16GB flash memory are slightly inferior to the look.
The size of the second generation motherboard of the Micro Whale TV is moderate, and the layout of the overall device is relatively more structured. Each module has a clear logic, and the memory and the flash memory module are arranged side by side on the cooling module side. Each of the motherboard's configuration specifications is very clear, and the Mstar 6A828 chip and 2GB of memory + 32GB flash memory can be clearly found on the motherboard, but the processor and memory configurations are relatively low.
As we mentioned earlier, Xiaomi TV 4 has made huge optimizations in its internal design in order to create a thin and light body. The size of the natural motherboard is also relatively small, and the processor cooling module is obviously much smaller than the other five TV sets. However, the overall layout is still relatively regular. Millet TV 4 uses Amlogic T968 processor, although it can guarantee the smooth running of the system, but for the help of picture quality improvement, obviously not reach the level of Mstar 6A938. At the same time, the configuration of 2GB of memory + 8GB of flash memory has no advantage in the six TVs.
Although the Hisense VIDAA V1 motherboard is not dominant in size, each device is relatively tight, but it can be clearly seen that the logic layout on the board is very clear and neat. At the same time, the cooling module of this motherboard adopts a detachable design. The advantage of this is that it has a large heat dissipation area and can effectively guarantee the stability of the hardware. From the figure we can also see that the motherboard also uses the Mstar 6A938 chip, and also has 4GB of memory and 32GB of flash memory. The configuration is quite impressive.
The mainboard design of the PPTV N55 is the most balanced one among the six. It is not only reasonable in size, but the reasonable layout logic makes the entire motherboard look very neat, and in order to allow the processor and memory and other hardware to achieve a better cooling effect, The thermal module covers most of the area of ​​the motherboard. At the same time in the configuration is also in line with the flagship standard, Mstar 6A938 processor, 4GB memory +32GB flash memory, performed satisfactorily.
As the core module inside the TV, the motherboard plays a crucial role in the overall performance of the TV. Through horizontal comparison, the six major TV motherboards have done a very good job in the use of materials for work. This section will score three points out of the hardware configuration, interface parameters and layout neatness of the motherboard.
·Additional items: power board & LCD driver board
See still X55Q power board by SANHUA (Sanhua Industry) specifically for its custom production, power board layout is more compact, small coverage area, while the overall use of a black PCB board, with two cooling modules, the right side has more than one set of electrolytic capacitors Its capacitance can be very large, and it can better stabilize the circuit. HOT (The lines and components in this area cannot be directly touched by hand, otherwise the electric shock will be caused.) The &COLD partition is not obvious enough, and it is easy to cause accidental contact.
As a sub-brand of Skyworth, Coocaa is powered by Skyworth. The entire circuit board is very well-stocked and the coverage area is very impressive. Whether it is a thermistor or an electrolytic capacitor, there are multiple groups. At the same time, a white object similar to **rubber is seen in the figure as an insulating grease, which can effectively dissipate heat and protect the circuit. Cool open power board is also one of the few in the use of insulating grease, and HOT&COLD partition is very obvious and worthy of praise.
The power board of the micro whale behaves quite well. Although there is no absolute advantage in the overall use of materials, the logic of the entire circuit board is very clear and the layout is reasonable. There are multiple sets of thermistors and electrolytic capacitors to effectively protect the circuit. At the same time, each tiny module is equipped with a heat sink to ensure the safety of the circuit. The HOT&COLD division is obvious. On the whole, although the power board of the micro whale is not the most bulky material, it is definitely the most neatly designed power board.
Although Xiaomi TV 4 has optimized a lot of space internally, there is no “spoofing” (quoted) at the power board part. This power board is manufactured by Hansong Precision Parts and has multiple sets of electrolytic capacitors and toroidal inductors. At the same time, there are three sets of heat dissipation modules in the left, middle, and right parts of the power board to ensure circuit safety. The overall layout is reasonable, and the level of planning is clear. Each component is dense and not chaotic.
Hisense VIDAA V1 circuit board design is very neat, each regional module layout is clear and reasonable, full of materials, while the entire power board is almost occupied by the heat sink, effectively protect the normal operation of the circuit. The black square capacitor forms an oscillation circuit with a group of oversized toroidal inductors, and the thermistor can also suppress large currents at startup. There is also a layer of insulating pad at the bottom of the power board, which provides good stability while protecting the power board.
The PPTV N55 power board also uses a black PCB board, covering a relatively objective area, and the use of materials is also very solid. Multiple thermistors and electrolytic capacitors are provided in different module areas to provide a more stable and safe circuit for the entire power board. At the same time, transformers provide a stable source of energy for televisions.
·LCD chip comparison
In terms of screens, Kansei and Minke chose mainland China Star Optoelectronics, Hisense VIDAA selected Taiwanese manufacturer AUO, Cool Open and PPTV used South Korea's original imported LG Display, and millet chose another Korean maker. Samsung Display.
In fact, in recent years, with China's vigorous development of the panel industry, there has been almost no gap between the domestic screen and the imported screen. The quality of the image quality is not a screen can be divided, the most important thing is to look at manufacturers The ability to adjust the picture itself and the blessing of the TV chip.
This section scores mainly for the television power board material, layout, details of the processing to score points, although there is almost no difference between the LCD driver board, but the import panel due to cost factors or a bonus item. Power supply board and LCD driver board out of 4 points.
·Summary of results
After the appearance and internal dismantling of some scores, the final cool open tied with the first micro-whale, VIDAA and PPTV tied for second place, millet third, still see fourth.
· Six Internet TV dismantling reviews
To see still X55Q is representative of the brand transformation, in the overall design to break the shackles of homogeneity, but also to meet the public aesthetic. Hardware configuration Mstar 6A938 chip and 4GB memory + 32GB flash memory have reached the top level in current TV products. After internal dismantling, one can see that CAN still looks at the importance of sound quality performance. At the same time, reasonable layout and detailed control are also satisfactory. However, there are certain room for the use of hardware.
Cool open 55A3 design is a good addition, ultra-thin body and fabric bottom frame look more young and fashionable, while also using the configuration of the top Mstar 6A938 chip. From an internal point of view, although the space is slightly cramped, the overall structure is still very concise and the overall performance is very balanced through reasonable wiring and corresponding hidden designs.
The second generation of micro-whale TV still inherited the genes of the brand's low-key and steady, although at first glance it did not seem very amazing, but from the details of the place can see how little whales have the intention. The internal performance is also very balanced. Although the configuration and use of materials are not the best of the six TVs, it is like a good student who is obedient. There is no place for critics. This may be the way to success of the micro whale.
Millet TV 4 in the shape can meet the aesthetic of many users, ultra-thin 4.9mm can be said to have reached the limit of LCD TVs. But it is also adhering to this ultra-thin concept, Xiaomi TV 4 had to save more space, which also led to the use of hardware and configuration of the hardware had to be greatly reduced, this way, the shift did not eventually be able to continue Design success.
VIDAA V1 TV has also made enough difference in the design, Champagne gold color, hollow ring touch keys, triangle base are VIDAA unique elements. Although the overall internal layout is not the best, but from the core of the design logic, as well as the use of materials and configuration we can see the style of television manufacturers, in line with its high-end Internet TV positioning.
The PPTV N55, as a product transitioning to the high end, performed equally well in this comparison. The golden mirror base allows more people to love this TV. The internal work materials are also sloppy and the configuration is also in line with the flagship level. From these characteristics, we can also see the determination of PPTV's transformation.
Through dismantling, it is clear that the Internet TV industry's participation in the dismantling of the six major Internet TVs is a flagship product. Through this large-scale dismantling, we have also found an interesting phenomenon, although the current mobile phone, tablet and other equipment Frequently, but there are almost no cottage products in the television field, even if the threshold for TV is becoming lower and lower. This also fully shows that the main profit of Internet TV is not the product itself, but more value added through this terminal.
Based on this factor, we can also see that the difference between the internal Internet TV is not very big, almost all Internet TV manufacturers do not have a complete industrial chain, the screen and internal components are more to complete through procurement. Final assembly of the OEM. In fact, users do not need to worry about the use of Internet TV's materials, because this is not their most important profit point. Bundling users with rich content, building smart home terminals, and building a brand image with reliable and cost-effective products are what the successful Internet TV manufacturers are currently doing.

Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
