The basic points to pay attention to buy LCD TV

LCD TVs have basically replaced old and cumbersome TVs in the past. Although the threshold for LCD TVs is getting lower and lower, there is one for more than one thousand yuan. However, attentive friends will also find that there are often large-size and high-priced LCD TVs in the store. Does it mean that ordinary consumers need to use such high-tech products? The key point is, have I paid more than 10,000 yuan? Will it be able to bring such a surge of enjoyment?



It was with these questions that we invited a white user who didn't know much about high-tech LCD TVs to see how PK was between him and our advanced players.


Million yuan TV screen size is too large to use?


Xiaobai users: In the last century, there was a 21-inch spherical color TV set in the home. It was a very gratifying thing. Why are TVs now more than 30/40 inch? In my opinion, buying a 32-inch room or a 42-inch TV in the living room is enough! And isn't mother saying that you can't get too close to watching TV? I think that if my family has a 50/60-inch TV, I'm afraid I'll soon be nearsighted.



Advanced players: First of all, there is a common sense mistake in the above question. We get myopic eyes because of the irreversible damage that we have had with our eyes for a long time and the eye has not been effectively rested. This is not absolutely related to the size and distance of watching television.


Actually, when we buy TV, the ideal state is that when we watch it, the visual scene is just filled with the whole picture. This is a very ideal state, so that the picture of our TV will not be wasted, and we It also has great visual impact, which is why curved TV is now emphasizing the best curved surface that is completely in line with human eye curvature. However, because the family’s television is not viewed by one person, and the person’s eyes have an optimal viewing distance (the so-called 朦胧 is the United States, and the long-distance cannot see the graininess of the screen), so these two conditions must be integrated. Select the size of your TV. In general, the best viewing distance is estimated based on 4-6 times the diagonal of the TV screen. For example, a 32-inch LCD TV with a diagonal length of 40 inches should have a better viewing distance of 2.5 meters.



But now that 4K ultra-high definition televisions have begun to be widely used and the television screens have become more and more detailed, the requirements for viewing distances are not so far away. Therefore, after the 4K resolution of TVs, the viewing distance can be even closer.
