[written in front]]
I am very glad to be able to participate in this evaluation of the general elephant ~ ~ first of all, I am sorry that when I received the logistics, I was unable to get in touch with the products of this evaluation in the first time on a business trip in Sanya, but I heard the consistent evaluation of the female colleagues who helped to sign for it "how big!" I immediately felt a lot of pressure!

(How big!)
OK, don't talk about female colleagues, back to our main character this time, or let him introduce himself--

[Not First Meeting]]
Hello, everyone, I come from Letv super TV family. My name is Letv super TV F55 55-inch full screen 2GB 16GB large storage 4K ultra-high definition artificial intelligence network LCD flat panel TV. Is it harder to remember than Dalabeng Bade Bedibdo than Ruon, or else you 'd better call me F55!
Why do you say it is not the first time to meet? In fact, I met everyone in December 19. Now that half a year has passed, the TV circle has also experienced waves of heat and slots, but after watching everyone's appearances one by one, I suddenly feel alas! Although it is already half a year old, it seems that we can still fight again! Come on! Get me up!

[Let me speak]]
Well, let you briefly introduce yourself and write a long composition. Let me talk about it. This time, we'll talk about something different. After all, half a year has passed, although the evaluation on the major e-commerce apps is very good, whether you can really play, you still have to see is believing!

[1.0 Unpacking Machine]]
In fact, in the past, my evaluation usually skipped the unpacking link directly, at least skipping a lot. However, this time, because it is a TV product and a relatively large thing of 55 inches, the quality of the packaging and the feeling of presentation become more important. Therefore, this time, let's talk about unpacking, but we still talk about something different.
The development of modern logistics has covered almost any form of products that can be imagined. The familiar products such as home appliances are more mature. Our unpacking point this time is placed in those small but favorable places. First of all, let's take a look at this label that is really willing to spend money--

(The cause of occupational disease, for this kind of thing instead of catching a cold)
However, the packaging is still needed.

Internal padding is also very sincere.

Next, let's take out the main character and scan the whole body to see what advantages and slots there are.

The list is very simple and clear, the screen remote control battery (very considerate) base screw, and another important thing is the instruction manual. The other basic is the real picture of foam and plastic bag (slightly omitted).

(Take a picture)
Let's talk about the advantages first, after all, first courtesy and then soldiers! The small matter of giving batteries is really heart-warming. Just imagine the mood of going out to buy batteries without batteries, which is worse than today's rain. Of course, the biggest advantage is this screen. Let's put it behind us and talk about it slowly. Don't be so shy!

The biggest slot point this time is when assembling the two bottom brackets, the first is the bottom bracket full of plastic texture. In my impression, the bottom bracket of a certain merchant a few years ago was already a metal casting. The texture and the sense of weight in hand are still impressive today. However, Letv TV F55 can understand the use of plastic bottom brackets for cost considerations. And buy TV to watch the screen, use the configuration, this is also acceptable.
Uh-huh, don't cry, can turn on!

(What if the screen is so beautiful as to cry)

Close to perfect left and right corner details, round body, no light leakage, praise!

Jobs has discussed the back of the wardrobe. We will not make such high requirements for the time being. However, compared with the wardrobe, should TV pay a little attention to the back effect? The back of F55 can be described as a "back killer!

No blowing, no black, the remote control part is simple and direct, a large area of frosting, a small part of the bright surface restrained and elegant, praise!

[2.0 beauty, do you want to play together]]
In fact, I want to put this section in the first part, but I am really embarrassed to put it in front of the unpacking machine, so I can only resist the restlessness and endure to finish the unpacking machine. Now I can finally say to you loudly--
On the beautiful woman!

(If you want to make friends, please chat privately)
Don't get me wrong, we warmly invited beautiful colleagues to play games together. As for why we invited her, do you still need to ask for this reason? Of course, it is because-she has switch! But! Switch does not have a cable, fortunately there is PS4 spare tire!
Get on the spare tire!

In fact, we want everyone to directly see the real feedback about the product such as screen proportion, color rendering effect, picture quality fluency and so on through this game link. Forget it, let me play the game first and be with beautiful women!

One thing to say, the screen proportion of F55 is really strong, and the official data are 97% (the official is believed here, and the actual measurement is inevitably too much)

Through the whole game, there is also an obvious feeling of immersion. A little bit of sorting out the thinking. In fact, the landing point is still this screen. The obvious feeling is even, just like a door open in the dark night, with a uniform light rectangle of hope. I went to the official store to see the introduction of the screen. There is an interesting term "OD20 straight-down mixing technology". The reason why people are advanced lies in their curiosity, come on, let's find out who this OD20 is--
Interposition, there is indeed a little more interesting in the search for "OD20 direct mixing technology", as shown in the following figure--

Almost all of them are about F55 consultation. It is difficult for the author to throw away an idea: will this be another propaganda proprietary technology that has been forced out, such as ID without borders! So the author turned back a few more pages and finally found some normal search results.
End this curiosity with a picture and a comparison--

(There is a question that in theory, the side entry formula will be lighter and thinner)
Now insert a paragraph of analysis, too lazy to read such written text small partners can directly turn to the following to see the conclusion.
There is a paragraph in Zhihu about "how to choose the backlight of straight-down TV and side-in TV?" The answer, although the respondent is a certain manufacturer, but the content is also convincing. Let's take an excerpt--
"Difference:
Straight-down type: emphasis on excellent picture quality
Direct LED technology has better advantages in picture control than side-entry LED technology. Compared with the two methods, the "straight-down" performance of the picture quality is more perfect. Taking a 55-inch TV as an example, the direct-down product distributes more than 3000 LED lights evenly behind the panel, so that the backlight can be evenly transmitted to the entire screen, and the picture details are more delicate and lifelike.
In addition, the direct-type LED TV also divides the LED backlight into several cells. When displaying black, directly turn off the light in the corresponding LED area to show perfect black.
Side-in type: emphasis on ultra-thin energy saving leading
The thinner volume has become the biggest highlight of the side-entry TV. Therefore, the TV with side-in backlight is especially beautiful!
Having said so much, the straight-down type has better picture quality in general, while the side-entry type has a thinner body. The advantage of Letv TV F55 is that while it has the advantage of straight-down picture quality, the body is very thin, combining the advantages of both.

The picture is worth a portrayal!

Look at this resolution! Not the kui 4k (the gap between shooting and scene is still quite large) contrast and saturation are also completely OK, here is a wave of praise!

[3.0 Soft and Hard]]
Let the bullet fly with a section "Master Gao! The county magistrate is hard! Master Huang is tall and hard!" In my work, I often praise the soft and hard project manager who is dealing with the hardware department and the software department! So, how did our main character F55 perform in terms of software and hardware this time?
First of all, it is hard. After all, this is a real big guy in front of us. How many important things are contained in our body still need to be done one by one. F55 is equipped with 2GB of storage and 16GB of flash memory. 16G can be called the mainstream standard in the current market recognition. However, the number of competing products at the same price is 28, and the number of flash memory is doubled. It is worthy of praise. This, for example, you can download more applications in the application mall to expand the functions of TV, more video resources and more fun games.

In terms of sound quality, F55 is equipped with a 2 × 8W high-fidelity stereo speaker, and the image quality is equipped with a 55-inch 4K ultra-high definition screen display, which supports HDR decoding, 5000:1 static contrast ratio, 178 ultra-light viewing angle, 8ms fast response full channel SDR to HDR, extreme color and other image quality technologies.

Mainstream interfaces are readily available, including HDMI 2.0, USB 2.0, cable port, AV (set-top box), RF (cable TV), and audio output. There should be a lot of things, and the hard ones are really hard!

Let's talk about the soft part. After all, if the current intelligent hardware does not have the blessing of experience, it is really difficult to convince consumers. What are the differences between F55 this time?
In terms of content, F55 is equipped with an artificial intelligence system EMUI 8.0, which includes content classification, intelligent recommendation, carousel desktop, off-screen listening, timing shutdown, and smart home. At the same time, F55 also provides a "standard model" suitable for young and middle-aged groups, a "parent-child model" suitable for children, and a "concise model" suitable for the elderly for different family relationships, realizing multiple people and multiple sides. Let's choose a mode to comment briefly. Considering that children are staying at home recently, parent-child mode must be a good choice for many parents. The interface in parent-child mode will become simpler. Children can also operate themselves without causing headache. The content display will rank first with the content recently played (now the first choice for many children to turn on TV is to watch fixed programs they like, this function is very suitable for actual needs), other children's programs will be displayed in turn. Of course, parents are still urged to accompany their children more and watch TV together!

However, there is an interesting and incredible place that F55 contains boot advertisements and cannot be closed (there is no VIP ad-free mode) but the playback content can be customized. Although this design does not look very good, if you think about it carefully, domestic TVs have startup advertisements. It is a little strange if there is no picture but an empty screen during the startup waiting period. Letv TV supports customizing startup advertisements to other videos, which seems to be the best solution. (The author replaced the boot video with Sadako, which was just used to frighten beautiful women. It was really a' ha, ha, ha, ha, ha hiccup')
In terms of soft interaction, many scenes of F55 are realized by remote controller, but different from the conventional TV remote controller, F55 is equipped with 16-key intelligent voice remote controller, which is not only convenient for daily high-frequency operation of super TV, but also can realize complicated functions such as weather checking, video playing and application opening.

[4.0 end]]
Uh-huh, let's close it. In fact, the overall evaluation can be summarized in one sentence. F55 has devoted more energy to the screen and configuration that users care about most (of course, this is also the most important component of TV products), but it has also sacrificed the presentation effect of plastic parts details to some extent, but the performance of the software side has also made up for the lack of presentation of details. On the whole, at a price of less than 2,000 yuan, it is impeccable to buy a TV with this configuration.
Looking forward to Letv's persistent efforts to provide better products!
