With the rapid development of smart TVs, 4K TVs and HDR TVs have become the most important display technologies for smart TVs. However, for many ordinary consumers, very professional terms such as 4K and HDR are not well understood, and many consumers are deceived by the manufacturer's slogan. Today Xiao Bian took everyone on science and technology to see what is HDR and true 4K display technology. 
What is HDR display technology?
HDR is actually called "high dynamic range display technology". The term was originally mentioned in the field of photography. It is a technology that can enhance the dynamic range of photographs. Now many smartphones support HDR shooting. It can take multiple shots. Different exposure photos were synthesized by HDR technology, and the processed photos and layers were more powerful.
Usually we use a ratio to represent, such as "200:1", "400:1" and so on. This value depends on the full range of brightness and the minimum level of brightness. It can be seen that the larger the dynamic range, the contrast and the color accuracy. It is better to see with the naked eye the display of images is clearer, the sense of hierarchy is stronger, and the colors are more abundant.
What is 4K resolution?
The 4K resolution means that the pixel value of each line in the horizontal direction reaches or approaches 4096, and in most cases it specifically refers to a resolution of 4096*2160. Of course, depending on the use environment, 4K resolution also has a variety of different resolutions, such as Academy 4K 3656*2664 and UHDTV standard 3840*2160, etc., all belong to the category of 4K resolution.
The standardized 4K (3840 horizontal pixels) can reach 4 times the HD resolution. At this resolution, people can clearly see every detail in the picture. The experience that comes with bright colors and super-real sound is great.
