What does 4K TV mean?
At the just-concluded 2015CES show, 4K TVs continued their glory last year. Major TV manufacturers rushed to launch their latest 4K TVs, and as a result, people in the industry said that the 4K era has arrived. However, from the user's point of view, this is simply a paradox. Many friends still do not know what 4K TV means? Where did the 4K era come from. Friends, now that you don’t know much about 4K TVs, quickly go with the author to see what is 4K TV.
What does 4K TV mean?
Some people say that the 4K TV is an Ultra High Definition (UHD) TV with a resolution of 38402160 (4K2K) and a resolution of 4 times that of a full HD (FullHD, 1920×1080 resolution) TV. In fact, this statement is not correct.
Strictly speaking, 4K TV resolution refers to a TV set with a resolution of 4,096,260. As many TV manufacturers and media have called Ultra HD TVs as 4K TVs, gradually, 4K TVs and Ultra HDTVs are drawn. The equal sign, but we must know that this is two different concepts. Based on the above reasons, in the domestic market, 4K TV refers to a TV with a resolution of 38402160.
What is the resolution of the TV?
The pixel resolution refers to the number of pixels displayed on the screen. The higher the resolution, the greater the number of pixels, and the more precise the sensed image, it is like a mobile phone or a camera. The more pixels there are, the better the picture is taken. With the same screen size, the higher the resolution, the finer and more detailed the display.
For a screen with a resolution of 38402160, that is, each horizontal line contains 3840 pixels and there are 2160 lines, that is, the number of scanning columns is 3840 columns and the number of rows is 2160 lines. The total number of pixels = 38402160, about 800 million.
What are the advantages and benefits of 4K TV?

It can make up for the loss of 3D resolution and make every detail of the picture perfectly visible. More delicate and clear, even the fibrous pores of the face can be seen very clearly.
2, the same distance, larger size. When watching a high-definition television at a certain distance, if the screen is too large, the human eye will see the pixels and form a grainy appearance. Looking at the 4K ultra high definition television at the same distance, the human eye will not see the pixels, allowing you to enjoy the wonderful view of the big picture at a closer distance. 4K Ultra HD shortens the viewing distance by half. Your vision is completely occupied by the TV screen and takes you to an immersive entertainment experience.
3, compatible with 1080P full HD film source. Through intelligent calculations, 4K TVs can compensate for image tracking on the space axis plane, inserting four pixels around each pixel point, accurately restoring line and field information in the horizontal and vertical directions, and increasing the amplitude to 70%, enabling the full HD picture to be achieved. Approx 4K Ultra HD display effect. The HDTV channel 1080i is enhanced by 2.89 times resolution through the set-top box.
