OFweek smart home network news: Speaking of the domestic smart TV industry in the field to do the manufacturers of wind and water, we are the same as the evaluation of the king, the first time I thought of is millet and music as. Millet and LeTV have all experienced more training in the Internet TV industry. However, recently TCL's high-end Internet brand Thunderbird, released a new I55, officially launched its Internet TV brand, this release instantly attracted many eyeballs, of course, there are also some doubting voice, just, our assessment The room has already purchased millet 3S and music as super 4, also after the TCL conference to obtain the Thunderbird I55 prototype for the first time, we will come and have a look at 36 years of experience in the television industry, to open up the industry's entire chain of emerging forces, Ray How is the bird TV performance?
First, the value of PK
Thunderbird TV I55 uses a full metal frame, integrated body design, plus diamond design elements, it is in line with the modern young people's aesthetic and various home styles. The first time I saw Thunderbird TV was amazing, Xiaobian suddenly liked it.
LeTV Super 4 only has a simple three-sided metal front frame, the back of the shell using a traditional backpack, the front is relatively simple, side and rear view and other TV is no different, and a lot of screws.
Millet 3S overall color dark, lack of bright spots, also used a metal front frame, supplemented by embossing process, the back is a traditional backpack design, screws exposed; overall, lack of bright spots, quite satisfactory.
1. Front frame:
Thunderbird I55 front frame for the aviation aluminum material, innovative use of five diamond design, workmanship is very fine, basically seamless, because it is five-sided design, it looks very narrow frame, and different angles can feel texture The metal luster; In order to meet the needs of different users, matching the furniture environment, launched a total of four colors, Xiao Bian each one is very fond of.
Music as the front frame of the super 4 is also a metal material, the use of three-sided bending, looks relatively simple, quite satisfactory;
Millet 3S front frame is also a metal material, the color is darker, the front frame adds a circle of embossing, the workmanship is more refined, but the overall metal texture is not strong; millet 4A changed to a plastic frame, and the machine is very thick, not comparable Sex.
2, back:
The design of Thunderbird I55 is also very smooth and concise. The way to integrate hidden traces can only be seen on ultra-high-end machines. The entire back can't see screws, and it is very stylish and clean.
Millet 3S and LeSky Ultra 4 still have a backpack-like appearance on the back, and screws and exposed lines can be seen everywhere.
In terms of the degree of cleanliness of the backplane, artistic aesthetics, and fine workmanship, the Thunderbird I55 is superior.
3, base:
Thunderbird I55 uses a hollow metal base, also has a diamond element, and the frame is perfectly docked, full of artistic sense, the whole is very coordinated and solid;
The base of millet 3S is a common type of pedal. The workmanship is excellent and the sense of style is slightly insufficient.
LeTV's cloud base, unique shape, more artistic, like it would like it, do not like it will feel unstable, too grab the limelight TV, and the price is more expensive.
4, lights:
Thunderbird I55 uses a crescent-shaped design, the indicator light brightness is soft, very uniform texture; in the switch machine process, the specific application of the scene, there is a breathing effect, very clever and clear instructions; the most let Xiaobian happy, can Set to sleep mode, the indicator will go out after standby, without affecting sleep at all
5, human design
Thunderbird I55 side put a USB, even if the wall, users can easily use the USB, you can easily see the local video and pictures! This is very intimate, Le Vision and millet's machines do not have this humane setting;
In general, in terms of design, materials, workmanship, and humanity, Thunderbird TV is even better. As a 4K Internet TV with a price of less than 4000, it far exceeds Xiaobian's expectations. It can be seen that the Thunderbird I55 ratio. Other Internet brand TVs are more attentive!
Second, the hardware contest
1. The main parameters
As the industry chain matures, the production of electronic components of products is highly centralized. At the same price segment, it is difficult to see a one-sided fall from the hardware configuration. The overall configuration is basically similar, and this time is to test the industrial chain of the enterprise. With the ability to integrate control and control, and relying on the top three TCL TVs in the world, hardware R&D and supply chain control are unmatched by other Internet brands. Let's take a look at the comparison of the main hardware parameters of the three televisions.
From the above parameter list, you can see the advantages and disadvantages of each product, Le Super 4 compare chicken thief, in the white and white users are more concerned about the RAM and ROM gives a more beautiful data, millet 4A and millet 3S no highlights It can be said that Thunderbird I55 configuration is more balanced, the configuration has, you can also see the Thunderbird market sincerity.
2. Internal arrangement
The listed parameters are the economic strengths of the manufacturers, and the internal stacking is the testing hardware of the manufacturers. Let's look at the comparison of the two internal structures.
Thunderbird I55-UI
LeTV 4
Thunderbird's internal layout is very concise. It is a manifestation of TCL's deep intelligent TV technology capabilities and technological level. Compared with other newly added brands, it has a higher level of manufacturing technology. Simplicity means that the quality is more reliable and the probability of problems is higher. Smaller, it requires deep industry accumulation.
Thunderbird TV adopts the industry-leading breakthrough Lips power system, which combines the drive and power supply into one. LeTV uses the traditional PSU+Driver 1+1 power system. Lips power has outstanding advantages: high system integration, saving internal space; improving power efficiency, environmental protection and energy saving; reducing internal wiring, reducing the reliability risk caused by the connector;
3, the motherboard
In terms of movement, the Thunderbird I55 and LeTV Ultra 4 are all using Msatr's latest generation of smart TV cores. The I55 uses the MS838A and the LeTV uses the MS938. The two chips have an integrated MEMC module and use a nano cooling system. The overall performance is better than Millet 3S and 4A movement
4, comparison of high-frequency head
Thunderbird I55-UI high-frequency head adopts full-shielded type, strong anti-interference ability; while millet 3S high-frequency head adopts partial shielding, and has poor anti-interference ability.
6, DDR speed comparison
Thunderbird uses 64bit CPU, DDR bandwidth 64bit, to achieve true 64bit bandwidth, and millet 4A DDR is 32bit bandwidth. In addition, Thunderbird's DDR speed is as high as 2133MHz, further increasing the speed of over 30% of Xiaomi. So that the operation is easy and smooth and natural! From the point of view of the DDR memory space, Thunderbird and Xiaomi have adopted a mainstream configuration of 2GB. In terms of the smoothness of video playback, Thunderbird TV with a 2133MHz DDR clock frequency is more advantageous, accounting for a larger memory game. In the scene where switching is initiated, LeStra 4 with more memory has advantages. From the test of practical multi-application tasks, Thunderbird I55 and Leshi Super 4 performed quite well, better than Xiaomi 3S and 4A.
In terms of hardware, the Thunderbird I55-UI wins the overall strength, LeTV's overall performance is slightly worse, but the courage to invest in the movement, millet fell into the wind.
Third, quality competition

A, brightness reduction
B, color reproduction
C, HDR screen
Look at HDR quality comparison
Millet 3S HDR display
Thunderbird I55 HDR display effect
The HDR status of Xiaomi 3S is unstable, and the screen is sometimes pale and loses its level of contrast. It shows that the millet 3S technology is not yet mature on the HDR display. In contrast, Thunderbird I55's HDR display has saturated colors, bright colors, and a much better viewing effect.
2, Thunderbird I55 VS Millet 4A
A, brightness reduction
The low-middle signal of Xiaomi 4A was too low, resulting in dark scenes without detail and darkness. Thunderbirds can see the details of the dark shadows.
B, color reproduction
Thunderbird's color reproduction is more accurate. However, millet 4A has a large deviation. Performance in line with objective tests
3, Thunderbird I55 VS Le Super 4
A, brightness reduction
LeTV X4 under the HDR source, the dark picture is too dark, lost many details, the dark picture, the character face details such as the basic invisible, while the color saturation, distortion. LeTV X4 HDR display is poor.
B, color reproduction
LeTV Super 4 color reproduction is inaccurate. Color oversaturation and distortion. Sudden color transitions often appear stained. Thunderbird's color reproduction is relatively accurate and the colors are more realistic
4, dark screen plane light leakage
The above four screens are the dark screen plane light leakage test of Xiaomi 3S, Xiaomi 4A, Leshi Super 4 and Thunderbird I55-UI. In the dark scene or scene transitioning process, Thunderbird's dark screen light leakage Best, almost no light leakage. Millet leaks light, but LeTV not only leaks light, but is uneven, showing obvious light spots.
5, smart quality - Thunderbird I55-UI unique
The figure above is a comparison chart before and after the intelligent image quality is turned on/off in a dark environment. In the dark environment, after the intelligent quality is turned on, the picture is much more comfortable and the sense of hierarchy is better.
The figure above is a comparison chart before and after the intelligent image quality is turned on/off in a bright environment (200Lx). In a bright environment, after the intelligent picture quality is turned on, the details of the dark parts of the picture are clear and without losing the sense of hierarchy. It seems that intelligent image quality can indeed adjust the picture effect according to the ambient light conditions to achieve the best viewing effect.
6. Comparison of picture quality
Integrating the above dimensions, Thunderbird I55 carries the TCL's top domestic debugging capabilities in picture quality. It is indeed superior in picture quality performance and close to the needs of users. LeTV and Xiaomi are only pursuing parameters, and they are able to adjust their picture quality. The quality of the processing technology is lacking, and we need to continue our efforts.
