You must understand these four points before you buy a TV to be able to choose the TV that suits you best

The size of the TV is undoubtedly the user's initial and most intuitive experience of a TV set. How much more suitable to choose a big TV? First of all, we need to understand one thing - TVs can't be too small. They can look like a lot of effort. They don't look good at home. They can't be too big. If the TV's picture exceeds people's vision, they need to go back and forth when watching TV. Swiping your head to see the full screen looks tired.

The recommended size is based on viewing distance -

The viewing distance is within 2.7 meters, and the recommended distance is not more than 43 inches.

The viewing distance is within 3 meters, it is recommended not to exceed 50 inches;

The viewing distance is within 3.3 meters and the recommended distance is not more than 60 inches.

The viewing distance is within 4.2 meters and the recommended distance is not more than 70 inches.

Within the recommended range, the larger the TV, the better the viewing effect.

LED or OLED?

LED screen, also known as the LCD screen (LED screen is the concept proposed by Samsung, the initial LED screen in the promotion, known as better than the LCD screen. But later people found that the LCD screen and LED screen is exactly the same thing, so All manufacturers are saying that they are LED screens.) It is a product that has taken a step forward in the imaging of kinescopes. It is also the imaging body used in most TVs on the market today. It is affordable and easy to use.

The disadvantage is that the LED screen itself can only be imaged, there is no light-emitting function, and it needs to cooperate with the backlight (the imaging body of the LED screen is not an LED, but a kind of liquid crystal, so it is called “LCD screen”. The LED only provides backlight for the LCD screen). The OLED is based on liquid crystals with an increase in light-emitting function, thus greatly improving the viewing angle, sharpness, and contrast. However, the price of OLED is much higher than the LED screen.

Direct-type backlight or side-entry backlight?

Since the backlight is mentioned, it is necessary to elaborate. The backlight of the LED screen is also different and is divided into a direct type and a side type. The direct type is to place a uniform LED light board directly behind the liquid crystal; the side-entry type is to place the LED light body around the liquid crystal, and then the light guide plate behind the liquid crystal is illuminated to illuminate the liquid crystal.

It is not difficult to imagine that the direct type backlight can better play the performance of the liquid crystal, showing the contrast of the picture is stronger; the advantage of the side-entry type is that it occupies a small area and can make a thinner and lighter TV body, but it will lead to The brightness around the screen is higher than the center and the temperature is higher than the center.

Straight or curved screen?

The so-called “curved TV” means that the screen of the TV is a curved surface. It is said that this arc is the same as the curvature of the human eye, so it seems that the damage to the eyes is relatively small. However, the curved screen has a smaller viewing angle than the candy bar screen and cannot be wall-mounted.

In short, curved TV is still a fresh object and has not been tested by the market. After all, the curved screen in the future will completely replace the candy bar screen and become the mainstream of the market. It will still be just a transitional product like a plasma TV, and it is still not conclusive.

Soft screen? No need!

Some manufacturers have developed so-called new products - soft screen. It is said that compared with the traditional hard screen, there are advantages such as clear imaging and stable picture, but in fact, compared with the two, it is only the difference in the production process, and it is almost the same in use.

There are many factors that affect image quality, including color number, HDR, color gamut, contrast, and resolution. The most commonly mentioned parameter is “resolution”, so only the resolution is interpreted today.

There are two kinds of resolutions for common TVs on the market. One is 1080P (1920x1080 resolution), which is actually normal definition. Businesses have given it a new name, called "HDTV." The other is 4K (3820x2160 resolution), and the resolution is 4 times the former.

Here is not to say that the higher the resolution, the better. There are two things to note when choosing:

1. The best resolution of a television is its highest resolution. If you use other resolutions, it will have an effect on sharpness. For example, setting a 1920x1080 resolution with a 4K TV, the picture resolution at this time is much inferior to a 1080P TV; using a 4K TV to watch a video signal with a lower resolution, the resolution is not as good as a 1080P TV.

2. The resolution of the TV is related to the size. If the size of the TV is too small, even if its resolution is high, it cannot show high definition.

Today's TVs are mostly smart TVs. If they are bought for the elderly at home, they are advised not to buy smart TVs. They will not look at them anyway, and they will double their prices in vain.

Smart TVs, like smart phones, have their own operating systems. Is there enough system? Of course not, there is its corresponding processor, memory, etc. Although the configuration of the television is far inferior to the mobile phone, it is still necessary to make comparisons and choices at the time of purchase.

By the way, the TV system is now confusing and many TV manufacturers are withdrawing from their systems. Is this system really good? However, it is implanted with its own company's software, when the time to download the software can not, can not delete the unwanted, every day suggest that you do some unknown video site members. Until the next automatic upgrade of the system, the software of the member's website could not be found. Instead, another video site was given to the TV manufacturers.
