Well, that's all for my sharing, I hope it will be helpful to you.

The larger the size of the TV screen, the greater the immersion given to the audience, which is why the TV screen is getting bigger and bigger now. But it's not the pursuit of a large screen,It's to choose as large as possible in the right range,And to take into account picture quality、Sound quality、Intelligence and so on。

When many families buy TV,The first reaction is to buy a big one,I think the size of the TV must be as big as possible,How cool it is to look at the big screen! Many people think that only a large screen can bring shocking audio-visual effects, so it is natural to buy directly according to the maximum size.

First of all, we need to pay attention to one concept - **distance.

**Distance is the actual distance of the TV distance**,If this distance is too far or too close,It will have a bad effect。 For example, if the distance is too close, it is easy to cause visual fatigue, and the picture will produce a slight graininess and become less realistic. If the distance is too far, the details in the picture will be lost, and some smaller fonts such as subtitles will be unclear, which will affect the effect.

Therefore, the size of the TV is not the bigger the better,But in a suitable range to achieve the best**effect,You can refer to the above formula to choose the TV size against the estimated distance of the TV。 The news that comes to mind here is that LG will bring its first and the world's largest microLED TV at 175 inches at IFA, which will open at the end of this month. This is the performance of the blind pursuit of TV size,According to the formula derived above,Its**The distance should reach meters to be appropriate,And most people's living room reservations**The distance will not exceed four meters。

Wow, it's really a special model for local tyrants' mansions! ）

Therefore,When we usually buy a TV,It's really not as big as possible,The key is to choose the right size according to the actual situation of our respective families,In order to ensure the best ** effect。

No, this is determined by many factors such as personal perception and distance. Choose the wrong TV screen size, you will not be able to see clearly if you are far away, and it will cause eye pain if you are close, so you must pay attention to the choice of size. Here we can popularize science, we often say that the size of the TV is not the length or width of the TV, but its diagonal.

It is very important for us to watch TV healthily and correctly, and to protect our family and our own eyesight. Of course, you must choose the size of the TV to better protect your eyesight. So how do you choose?

There is a universal formula for this that we can refer to. The best ** distance of LCD TV = screen size, which also has to be combined with the length and width of your own living room and bedroom, far away will not achieve the best visual effect, but close will damage your eyesight. We can assume that the room length is 5 meters, minus the necessary furniture to take up space, and with our actual viewing angle**, choosing a 63-inch TV is optimal.

With the sharp dive in the LCD TV market this year, you can now buy a 70-inch TV for more than 2,000. Many friends who want to buy a TV begin to worry about whether they can buy such a large TV at the distance of their living room,Will it look tired or affect eyesight,Then I'll help you answer this question。

Maybe you have seen the recommended size standards given by TV businesses or so-called industry associations,Most of this standard a few years ago**Distance 3 5 meters is recommended32 60 inches,Now the same**distance is basically recommended60 80 inches,Why is this happening,Merchants will explain that now the definition of TV has improved,So a larger size is recommended。

But in fact, the real reason is that the distance between the general family ** is almost no change in the range of 3 5 meters, but the merchants will recommend the inventory of products to consumers, as the size of the manufacturers is getting larger and larger, then the recommended to consumers is getting bigger and bigger.

So don't get scammed by merchants anymore! So how do you choose?

Since we are worried that the eyes will be tired, let's look at the most comfortable state of the human eye, and studies have shown that the best horizontal viewing angle of the human eye is 36 degrees, which will have a very good sense of visual presence, and will not cause fatigue due to frequent eye movements.

Bigger isn't always better. The size that fits the background wall of your home is very suitable, and only the right one is the best.

The choice of TV,As far as the living room is concerned,We recommend that it is best to choose55Inch and above size,Because the current mainstream size is55Inch,Generally3Distance**Distance can be selected55Inch TV,So that the eyes are also very comfortable to watch。

The bigger the TV, the better, if the living room space at home is not very large, you must choose a TV with the right size, otherwise it is not good for the eyes and it is very tiring to watch TV.

Summary. According to the standard, the size of the TV screen refers to the length of the diagonal of the effective picture of the TV. You can take the size by looking at the manual.

In addition to marking the size in the model number, in the manual of the TV, the manufacturer usually indicates the actual length and width of the TV screen in millimeters. For example, the size of a TV is marked as", which means that the length of the TV is centimeters, and the height is centimeters, according to calculations, it can be concluded that the length of the diagonal of this TV is about75cm, converted to inches, and rounding shows that this TV is30Inch.

Recently, 10 brands of color TVs at home and abroad, a total of 34 models, have been measured. Among them, there are 22 models of TVs that are advertised or marked with a large difference from the actual size, and the model with the largest gap is marked as 74 cm (29 inches) of a certain brand of TV, and the actual screen visual size is only 67 cm (inches).
