With the rapid development of science and technology, the specifications and parameters of TV screens are becoming more and more exquisite. The names and models are more "fancy", such as 8K, 4K, 2K, UHD, FHD, 3D, smart, OLED, etc. What exactly do they represent and what are the differences? Today, 360 common sense will decode all kinds of new TV styles, so that you can understand how different TV styles are, and let consumers know what they are paying for.
The key determinant of a TV's image quality and comfortable viewing is the screen. Some basic and simple methods can be used to roughly check whether a TV screen is good or not.
Tip: you can turn the TV to the black screen, and then see if it is black enough and even. If it is not even and black enough, the screen quality of the TV is not particularly ideal.
In terms of functions, it is suggested that consumers can choose models with 3D and intelligent functions. For example, smart TV refers to a program provided by a third-party service provider, such as a smart phone, equipped with an operating system, which can be installed and uninstalled by users themselves, such as software, games, etc. through the program, the functions of the TV can be continuously expanded, and the Internet can also be accessed directly to get more information.
If there is no such demand, you can buy ordinary TV sets at a cheaper price. In addition, you can also consider buying TV sets with energy-saving technology, which will save electricity and money in the long run.
How many inches of TV should I buy? The decisive factor is the viewing distance, that is, the actual distance from the audience's sitting position, their eyes to the TV's placement position.
General recommendations are as follows:
*2.5m is suitable for purchasing 32 inch TV;
*2.8m is suitable for 40 inch TV;
*3 meters for 42 inch TV;
*3.5m is suitable for 46 or 47 inch TV;
*4 meters is suitable for buying TV sets over 50 inches.
Large screen size decoding
2K电视机也称FHD（即全高清FULL HD），意思是全高清，全名为Full High Definition，一般能达到分辨率1920×1080。当你的片源达到1080p清晰度的时候，支持FHD分辨率输出的LCD电视机 就能将之完整表现出来。
2K TV is also called FHD (Full HD), which means full HD. Its full name is full high definition, and it can generally reach a resolution of 1920 × 1080. When your film source reaches 1080p resolution, LCD TV that supports FHD resolution output can fully display it.
4K (UltraHD or UHD) TV sets have higher screen physical resolution, which is 3840 × 2160, four times higher than full HD TV sets. It can receive, decode and display TV programs with corresponding resolution video signals. In this resolution, the audience can see every detail and close-up in the picture, and feel the experience of experiencing the scene.
◆ 8K 16 times Ultra HD
The 8K UHD resolution (7680 × 4320) of 8K TV is 16 times higher than that of 2K (Full HD) 1920 × 1080, and the resolution is 16 times higher than that of Blu ray.
Its horizontal viewing angle is 100 °, which is the best display environment for 360 ° panoramic display technology. It is much more exciting than the horizontal viewing angle with 2k and 4K resolution of only 55 °.
3D is the abbreviation of three-dimensional, which means three-dimensional graphics. 3D LCD TV is to add a special precision cylindrical lens screen on the LCD panel, and send the encoded 3D video image to the left and right eyes of people independently to produce a stereo effect, so that users can experience the stereo feeling without the aid of stereo glasses, and can also contain 2D pictures.
OLED organic light emitting diode
OLED（Organic Light-Emitting Diode）全称“有机发光二极管”，是一种最新的显示屏幕技术。相对液晶电视有着革命性的进步，无需液晶电视的背光模组，其屏体自发光。
OLED (organic light emitting diode) is a new display screen technology. Compared with LCD TV, it has a revolutionary progress. Without the backlight module of LCD TV, its screen body is self luminous.
This can make OLED TV have the advantages of infinite close to 100% pure black, infinite contrast beyond the naked eye, fast response, ultra wide viewing angle, non-toxic panchromatic domain, etc. OLED organic TV uses four-color 4K self luminous body as the display core. The color display is very accurate, the light control ability is good, and the color is too natural and harmonious.
