Television generally refers to equipment. It uses electronic technology to transmit moving images and audio signals. British engineer, John Logie Baird invented it in 1925. People regard television as "one of the most important inventions of the 20th century". Up to now, TV sets are necessary household appliances for every family. Science and technology developed a lot. TV sets are gradually being updated. Recently, 4K technology for TV sets has appeared. So, what does TV 4K mean?

We should first talk about 4K display technology. Then we can talk about 4K technology of TV set. 4K display technology is a new digital movie resolution. Hollywood movie producers released it. It involved many parameters. The proportion of movie screens is different. the horizontal coordinates of most 4K screens are concentrated at about 4000 points. The vertical coordinates are unified at 2160 points. The dots here refer to pixel dots. We can see the 16: 9 household digital TV. The 4K standard shows 3840 × 2160. Through calculation. We can conclude that 4K TV has 8 million pixels. In the past, the so-called full HD TV 1920*1080 had only 2 million pixels. It is four times as many as the latter. In addition, the progressive scanning line of the display device under 4K specification can reach 2160. We often referred it as 2160P. This type greatly improves the visual experience of the viewer.

The International Telecommunication Union issued "UHDTV" standard in May 2012. The industry calls televisions with a physical resolution of 3840 × 2160 and above 4K televisions.

The definition of 4K TV borrows the concept of projector display resolution. The resolution of mainstream business education projectors is 1024 × 768. TV of 720P household projectors is 1280 × 800. We can call it 1.3 K in principle. Define 1920 × 1080 in full HD as 1.9 K.

Therefore, 4K TV is 4 times the horizontal pixel point of flat panel TV display resolution of 1024. The resolution is 4096 × 2160. In other words, flat-panel televisions that reach this resolution are 4K televisions.

4K TV has the following advantages. First, its screen resolution is high. The playing picture can be clear and natural. Secondly, its computing power is strong. It can respond to the user's operation behavior more quickly. In addition, it has a wide color gamut. It can express various color qualities that 1080P TV cannot show.

Of course, these advantages are inseparable from the 4K display panel of the TV set. The 4K display panel of TV set is mostly made of oxide thin film transistors. It has high electronic movement speed. It has high resolution of the presented picture content. The frame is thin. The TV set is lighter and thinner. The picture is more detailed. The application of 4K display screen on TV is common. Some general TV uses 4K display effect. Their price and performance improved.

The above are some contents about 4K TV sets. I hope it can provide reference for everyone's purchase.
