In a large number of Internet-branded TVs that have emerged as a tide, curved TVs have always been a relatively niche phenomenon. Consumers have very little room to buy (usually only 2-3 brands, 4-5 models, even if the count The total number of traditional brands is also far less than flat products. The reason for this situation is not difficult to understand: the upstream core component of the curved TV - curved screen is relatively scarce, the cost is relatively high, plus the need for certain image quality processing technology in order to adapt the display characteristics of curved screen, Most uninterested Internet TV brands are naturally not willing to touch.
Fortunately, this is not a problem for TCL's Internet brand Thunderbird. Thanks to the panel resources of Huaxing Optoelectronics and the accumulation of R&D and manufacturing of TCL's complete machine, Thunderbird’s sales of the first 3 TV sets in 2017 will be given. The surface product retains a position.
This price of 4299 yuan, model "I55C" Thunderbird curved surface TV, regardless of product form, configuration, and price point of view, perhaps the most representative of Thunderbird characteristics, which is actually we have conducted a trial of it The most impressive experience, especially after experiencing Thunderbird's other two plane models, the I49-UI and I55-UI, was more prominent.
(It will take approximately 3 minutes to read the full text)
â— Objective analysis: Where is the market space for the I55C?
The general configuration of the Thunderbird I55U is as follows: Huaxing Optoelectronics' 4000R curvature 55-inch 4K panel, and equipped with MEMC, zero flash, anti-blue eye protection technology; intelligent configuration for the Mstar838A 64-bit processor, Cortex A53 quad-core 1.7GHz CPU and Quad-core T820 GPU, 2GB DDR3+16GB eMCC5.1 storage; MIMIO 802.11ac wireless network and Bluetooth 4.1. Overall, it is the more mainstream configuration of similar products.
I55U's main features are: Support full-format HDR (including HLG HDR10 and Dolby Vision); with 120,000: 1 high dynamic contrast and 450nit high brightness (conventional LCD brightness is generally within 300nit); with full color reproduction and precision light Controls two patented quality technologies, taking into account both quality and eye comfort. The system is characterized by the use of a simple, efficient FFUI, support for voice search, and through the cooperation with Tencent, Ali and other content providers, in Europe and the United States, NBA content has its own characteristics.
From the current market distribution of surface products, the cheapest 55-inch product is around 3300 yuan, while LeTV's 55-inch surface product is above 5,000 yuan. The price of Thunderbird 4299 is a typical median. Thunderbird did not plan to make the I55U a low-priced product. However, based on its hardware configuration and features, it is not difficult to find that the I55U has a clear price/performance advantage, especially in display performance such as HDR. Supporting Dolby Vision alone is enough to make it stand out from many competitors and is attractive enough. Differentiating features.
(tips: Dolby Vision is an image quality technology introduced by Dolby Laboratories, USA, which enhances the image by increasing the brightness and extending the dynamic range. It can increase the fidelity of the video signal, and thus make the image It is very realistic in terms of brightness, color, and contrast.)
As the final bombardment of Thunderbird's 3 TV trials, we will focus on the most differentiated areas of the I55U and the other two flat-screen TVs. For other general-purpose projects such as systems and content, interested readers can refer to the previous 2 evaluation trial articles.
â— Appearance
Although the I55C is a curved surface product, Thunderbird uses the same style as the other two flat products, including the most recognizable hollow base, the seamless one-piece ultra-narrow frame, and the buried back integrated back panel. Other family elements are used.
Curved TVs have three common curvatures: **0R 4000R and 3600R. 4000R is the most balanced one.
Hollow base became the most recognizable symbol of the Thunderbird
Ultra-narrow frame is also a family design
Thunderbird 3 models all use the same bracket (optional)
Curved TV always has two curvatures of **0R and 4000R. Relatively speaking, the curvature of 4000R is more in line with the physiological characteristics of the human eye. This is also the reason why curved TVs currently use 4000R curvature. The I55C also uses the curvature of the 4000R, and the overall visual sensation is more or less coordinated when placed on a TV cabinet.
Unlike European and American countries, Chinese home TVs are basically placed against the wall, so the backstab is not as fancy as the trunk
The back of the I55C also adopts a unique "hidden buried backplane" similar to Thunderbird's other two plane products. In particular, the hidden trunking design keeps the overall simplicity of the TV in the entire home environment. Beauty has a very practical value. In addition, Thunderbird uses a very traditional flame-retardant material on the backboard, but due to the overall design considerations, it seems to be more modern than many TVs using all-metal materials.
â— Quality
The biggest advantage of curved televisions and flat TVs is that they can provide "immersive" visual effects; if a curved TV can be based on this, it can do rich and accurate color control, and make full use of HDR's high brightness. Reproducing the range of characteristics, it is far from the icing on the cake so simple.
Let's take a look at the video quality performance of the Thunderbird I55C in the standard image mode, including 4K HDR content and normal 4K content. The specific performance will be explained in each legend.
The I55C has a style that makes the eyes feel very comfortable, vivid colors, but does not feel too exaggerated and strong
The gradient of the colors and the details of the details are vivid
Better reproduction of texture details, various colors give people a sense of harmony
The texture of the ingredients is well reproduced
When the picture has high brightness and dark field at the same time, the level of detail in different parts can be better reproduced
The image engine didn't do too much sharpening in order to highlight the sharpness. It didn't have the "dryness" feeling and it was very comfortable.
And the higher the source specifications, the better the performance of the I55C, and there is no obvious short board exposed
Perfect HDR support makes the screen more realistic when playing back HDR content, because the human eye is more sensitive to brightness
Next is the effect of 4K still images.
Clear outline, rich background haze detail
The color transition is more delicate
The background shadows are rich in detail, but due to camera latitude problems, there will be loss of screen shots.
For non-4K content, I55C also has a good display.
The white wall texture on the left is very clear, and the dark scene on the right also has many details clearly visible and unambiguous
The clarity of non-4k content is also good, there is no "painting"
Dynamic resolution test. Due to the built-in MEMC circuit, the I55C controls the fluency or smearing of the picture at a good level, and the user does not need to worry about this part of the performance.
In the end, we saw these high-resolution photos taken by ourselves, so we can also more intuitively test the I55C's color accuracy and detail display capabilities.
The blue water of the sea is clearly structured, which better reproduces the shooting scene
If you use the camera's color style to describe, I55C is like Canon, white balance is accurate, many details, and good levels.
The details of the clouds in the sky are accurately restored, and there are no losses in the details of the shadows.
Finally there is the actual test of the effect of online video playback. After all, what we usually look at is the content, not the various test strips.
Thunderbird's NBA event is also one of the special features, at this time the color, contrast performance is also very good
The picture dynamics of sports events are relatively large, and the I55C's fluency and trailing performance are sufficient
There are usually a lot of dark scenes in the movie. The I55C's high-contrast and HDR features give it an advantage in this mode.
The actual performance is a good sense of reality because the human eye is much more sensitive to changes in brightness than color
With the overall brightness kept dark, details in the shadow scene can be reproduced well. This is something that many Internet TVs cannot do.
The I55C is an excellent example of the advantages of 4K HDR shooting technology when watching 4K HDR's "Yueyue Biography".
In particular, the dynamic range of color and brightness, I believe that even people who do not understand technology can easily distinguish the difference between the quality of ordinary HD TV dramas.
In addition, compared with flat-screen TVs, curved TVs have the “emperor's bit†view, that is, the visual effects are best when they are in front of the screen. With the increase of viewing angles, the attenuation of visual effects is greater than that of flat-screen televisions of the same size. The effect of the I55C in different angles is as follows:
Positive color performance
There is no noticeable color shift in the picture at 30° angle
At 60°, the color shift is still not obvious
This 4,000-yuan price curved surface TV has very stable image quality in various application scenarios, including color accuracy, contrast, noise reduction, HDR brightness range, and dynamic resolution performance, and the picture is very comfortable to enter. It sounds like there is no technical content, and it's actually very difficult.
Other performance
In the special HDR theater area, there are currently about 50 movie contents, and the number will continue to increase in the future.
When Thunderbird’s carousel doesn’t know what to look for, it can directly watch the back-end manual programming
The I55C system is identical to the other two plane products
Thunderbird features: "Ding Theatre", which brings together many European and American high score TV dramas
Ann Bunny had a score of 330,000, which was a middle-class achievement. In addition to the relatively weak 3D performance, other performances were better.
This is a Bluetooth version of the voice remote control, the standard infrared remote control in addition to the lowest voice button, the other is the same
In the interaction section, the I55C is still equipped with an infrared remote controller. Fortunately, the Bluetooth remote controller does not have any difference from the Bluetooth remote controller. In addition to the simple and efficient operation of the FFUI system, it is relatively easy to use. of.
It is very convenient to find and open APP through voice function
Searching and playing videos is also possible, and voice operations can be used in any interface, further improving the operating efficiency
You can directly select episodes of TV dramas by voice.
However, we still strongly recommend users to buy a Bluetooth version of the voice remote control, because several Thunderbird machines have good voice recognition capabilities: whether it is to find video content, or find, open a variety of applications, through the voice function is extremely Convenience.
Due to the versatility of the software content platform and the performance of FFUI and video content, reference can be made to the evaluation of I49-UI and I55-UI.
â— Summary: Why is the Thunderbird I55U a spoiler in the curved TV market?
The reasons are summarized as follows:
1, the overall picture quality performance is surprising, it is difficult to imagine this is a 4000 yuan price TV performance.
2. There is enough recognition on the design, no longer be stereotyped.
In fact, for Internet-brand curved TVs, where the unit price is not too high, it is actually a very difficult task to achieve both quality, application, and content. Consumers often accept products based on price. In some aspects of the deficiencies. However, on the Thunderbird I55C, we did not find out in what areas it had a short board that needed to be compromised. This is why it can be defined as a spoiler for a curved TV market.
