In this year's "special" Spring Festival vacation, we all have to stay at home. At this time, whether it is at home in the Gwoyu lying type of pot play watching movies, or at home helpless remote office, we all need a hard core big screen TV. Because life needs a sense of ceremony, the TV screen is large enough, high-definition picture quality, multi-functional, which can meet our visual experience and entertainment experience, and even work just need.

So how to buy a good big screen TV, in fact, just combine the following four steps.

Part1: TV screen size to know

Nowadays, the home of the TV want to change the new, we will consider the pursuit of a more shocking audio-visual effect, give priority to the choice of large-sized TV, after all, a larger screen can make the whole picture filled with human eyes, the formation of a more intense immersive experience, no matter whether it's home with the When staying at home, whether it is used to watch movies, brush hot dramas, catch up with variety shows, play games, or video projection, it is a very addictive enjoyment. Importantly, large-size TVs are not easily outdated. However is it true that the bigger the TV, the better? Obviously this statement is not true.

When we buy TV size size, we also have to consider the size of the living room to decide. Because if the living room space is larger, the optimal viewing distance to watch TV will be longer, we need a TV with a slightly larger screen. And if a very large size TV set is installed in a smaller space in the living room, it will cause pressure on our eyes during the TV watching process, and it is easy to cause damage to the glasses. So, how to choose according to the size of the living room?

According to the scientific data measured by the best viewing angle of the human eye: the distance from the human eye to the screen 2.5m, you can choose a 75-inch TV; the distance from the human eye to the screen 3.5m, you can choose a 85-inch TV; the distance from the human eye to the screen 4.5m, you can choose a 100-inch TV. That is to say, 65-80 square meters of the house can buy 75 inches of big screen TV, 80-120 square meters of the house can choose 85 inches of big screen TV, 120 square meters above the house, then of course choose 100 inches of big screen TV can be.

Part2: The type of TV screen carefully

When it comes to the types of TVs, many people don't know the type of TV screen. There are these common screen types available on the market now: LCD TVs, laser TVs, QLED TVs, OLED TVs, and so on. Here are the differences between these four types of TV screens.

When it comes to "big screen", many people naturally associate LCD TVs and laser TVs together, because at present the size of these two types of TVs can easily achieve more than 100 inches. However, there is a huge difference between the two in terms of working principle, display effect and performance.

Taking laser TV as an example, since it is essentially an ultra-short-focus projector, reflecting light through the curtain to image, its brightness is often very low, and is easily disturbed by the natural light during the day. What's more, the viewing angle of the laser TV is very narrow, after more than 40 degrees, the color, brightness, clarity will show a precipitous drop, coupled with its noise, light leakage, short life, debugging trouble, etc., laser TV has also been criticized by users.

The LCD TV does not exist in the laser TV of these problems, its brightness is higher, stronger contrast, more realistic colors, higher clarity, high viewing angle, and does not produce scattering effect, at all times present a bright and clear picture quality. And regardless of day and night is not affected by ambient light, at any time you can see. At present, with the LCD screen price reduction, many people are inclined to choose a large screen LCD TV.

When it comes to "picture quality", many people like to compare QLED TVs with OLED TVs. What is the difference between the two, and how to choose?

QLED TV screen is composed of semiconductor nanocrystals, light and electrical stimulation will emit colored light, the color of the light by the quantum dots of the composition of the material and the size and shape of the decision, so a good material will be able to show more pure chromaticity, a wider color gamut. The lifespan of up to 60,000 hours, can be long-lasting rendering of nature's truest colors, the picture quality performance is perfect.QLED TV is also currently a type of TV in the city of high heat.

OLED TV in the screen production using light-emitting diode material, this material is easy to oxidize under prolonged use, so the service life of OLED screen is limited. Compared to QLED TV life of up to 60,000 hours, OLED TV life is only 30,000 hours, and a long time to watch is very easy to produce screen burning phenomenon, affecting the user viewing effect. What's worse, due to technical bottlenecks and costs, large-screen OLED TVs over 65 inches are still difficult to mass produce.

Part3: TV features are diverse and practical

Since we are going to choose a large-screen TV, we should definitely choose the smart one, and the practicality of these smart features should also be screened.

Taking voice control, it can be said to realize the vision of watching TV "without hands". Through voice control to realize the adjustment of various functions of the TV, such as searching for movies, increase or decrease the volume. At present, individual smart TV launched a support "no wake up" far-field voice function, do not need to repeatedly wake up the voice assistant can naturally control the TV, very humanized. There are even smart TVs that support a variety of dialects of voice control black technology, the elderly use is also very convenient.

Then there is this feature of intelligent recognition, which satisfies everyone's desire for knowledge, no matter when and where, by framing the subject on the TV screen, you can find relevant information about this subject from the Internet. For example, what other TV shows the main female character of the recently pursued drama has acted in, by framing the recognition, you can get more news, which can be said to be very thoughtful and practical.

In an era of big data, smart TV is not only a tool for us to enjoy our body and mind, but also an intimate companion that understands us more and more. A TV with smart push function can analyze the content you may be interested in according to your daily use habits and preferred source type, and then push it, so that your favorite content will be constantly available.

Additionally, Smart TVs can also serve as a learning and office tool.

In addition, some smart TV also has a remote video, screen projection and other functions, if necessary, can also meet the needs of the home office.

Part4: TV brands choose to have the strength of a guaranteed

As far as brands are concerned, domestic color TV brands have risen to the top, both in terms of quality and price, are not inferior to foreign brands.
