With the development of science and technology, intelligence has gradually broken into our lives. From mobile phones to tablets, from glasses to watches, intelligence has become a part of our lives. He really brings us many conveniences. , Make our life easier and easier. However, with the development of intelligence, the contents of film and television entertainment on the Internet are richer than those of cable television, and traditional television cannot satisfy users' use. People want to move things on the Internet to television, so smart TV came into being. However, there are not many users who truly understand smart TVs. Many users will face many problems when they purchase. Here, Xiao Bian recommends some TV smart tips for everyone to use in the future.
Select size
The choice of size is also a very important issue in the selection of television. Of course, TV is the bigger the better, but you have to consider the placement, size of space, and viewing distance. To know that the human eye's comfort zone is 60 degrees, in theory, knowing the distance the glasses watch the screen, you can know the best screen size to buy. What is the best viewing distance for a 4K TV? Usually the best viewing distance for a 50-inch screen 4K TV is about 1-1.5 meters, which allows a smaller indoor space to accommodate large-screen TVs larger than 50 inches. Even with a 65-inch big screen TV, the best viewing distance is shortened to about 2 meters and can be put into a living room of about 20 square meters. In addition, Europe and the United States calculated the display device, the best viewing distance, resolution and screen height of the three related formulas: the best viewing distance (cm) = screen height ÷ vertical resolution × 3400. Of course, not everyone agrees with this calculation. It is for reference only.
In fact, 4K TV refers to the physical resolution of the TV. As long as it reaches a resolution of 3840x2160, it can be called a 4K TV. Compared with the traditional 1080P full HDTV 1920x1080 full HD resolution, the definition of the TV is improved by four times and the picture is more refined with the support of the ultra high definition resolution of the 4K TV.
In fact, as consumers, they should keep their eyes open and not be confused by the propaganda of manufacturers or e-commerce. With regard to whether or not we should discuss how to purchase 4K TVs in one step, the author's proposal is based on his actual needs. If you are looking for the ultimate in picture quality, you may choose 4K TV. The lack of film sources is still a big problem, and some brands of 4K TVs have added 4K channels and 4K areas and other contents, allowing users to watch online 4K programs, which is also a compromise to solve the lack of film sources. Our proposal is to not blindly pursue the purchase of 4K Ultra HDTV. If users only watch some 1080P Full HD movies at ordinary times, then there is no need to choose 4K TVs. The price of 4K TVs is much higher than that of traditional TVs. Therefore, spending more money but not enjoying a high-quality experience has caused a waste of resources.
In most cases, the speakers of the TV can meet the daily audio-visual needs. When listening to sounds, the volume should be turned up, and attention should be paid to the characters and background sounds. In addition, try not to choose ultra-thin TV because the speaker needs space to express the sound, and the thickness of the ultra-thin TV limits the speaker. Of course, with an external stereo is also possible.
Curved TVs are indeed more visually appealing than flat-screen TVs. They are also better than flat-screen TVs in terms of viewing experience. They are called "immersive feelings." But the premise is that the TV screen is large enough to reflect the advantages of the curved surface. In general, the advantages of television surfaces with a size of 65 inches or more are more obvious. Curved TV center position works best. Second, at present, the price of curved TVs is much higher than that of flat TVs of the same level. Therefore, most curved TVs are high-end positioning products. On the other hand, the curved TV can get the best viewing experience in the center of the screen, and the edge position may be slightly inferior. Therefore, if there are more people in the family and sit around together, the curved TV may be a bit inappropriate.
Many people have ambiguous concepts about LED, OLED, ULED, SUHD, and so on. It's not clear what the difference is between them. When buying, it depends on the description of the manufacturer or the salesman. In fact, in addition to OLED TVs that can be seen on the market, others can be collectively referred to as LCD TVs, which are non-active light-emitting technologies. LCD TVs can be divided into the above-mentioned concepts based on the difference between panel technology and backlight technology. The different backlight sources directly determine the most intuitive experience of the color, brightness, contrast, etc. of the TV picture. Therefore, in the past two years, it has also become the technical focus of major TV manufacturers. The OLED TV is a technology that actively emits light from organic materials.
OLED has always been regarded as the most ideal display technology form at the present stage, and it must be the future development trend. However, LEDs, OLEDs, and ULEDs all have good performance in the display. Although there are gaps, they are basically only comparable. And OLED prices are relatively high, so for most consumers, do not use the meaning of these terms, do not deliberately pursue OLED. As long as it is a good experience, it is a good product.
First of all, to correct the two misunderstandings, the first one, the screen color can not just look at the panel, not because the "original LG screen" "original Korean panel" to think how good its quality, and how high-end. Secondly, we know that Taiwan, Japan and South Korea are the main regions for producing high-end panels, but they also produce low-end panels. Therefore, the quality of the screen cannot be determined by factions and regions. In fact, some domestic panels are also good. It depends on the integrated visual performance of IC design, imaging, and so on. Screen colors mainly look at the screen layering and solid color lighting. In general, TV malls will play video and movies in a unified way. We can compare the distribution of shadows and bright spots in the screen. The finer the screen, the better the screen. In addition, we can observe the screen's leaks and lighting conditions in a relatively dark environment. A good screen is basically the same brightness in the center and around. In addition to looking at the light, we must also observe whether there are yellow, reddish, and pan-blue color defects.
