Among the many features of high-end TV this year, the most attractive to us is the HDR display technology. In the past two years, the 4K ultra-high-definition screen of the hot blowout is about the resolution of the TV. The HDR technology emphasizes the perception of the human eye and the improvement of the image quality. The human eye has a wide range of perceptions of brightness, ranging from a few thousandths of a nit to millions of nits. The image quality ultimately perceived by the human eye is closely related to the final brightness range exhibited by the image output. The so-called dynamic brightness range, we can understand it as the range of the region between the highest brightness and the lowest brightness of the picture.
The range of brightness that traditional TVs can exhibit is extremely limited, far from what the human eye can perceive. The reason is that the brightness of the traditional TV in the bright part of the picture cannot be lifted, and the dark place cannot be dark. As a result, the human eye is finally perceived to have a poor layering and a large amount of detail is lost. HDR super-quality display technology came into being to solve this problem.
The smart TV equipped with HDR technology can expand the dynamic range of brightness and display a picture that is close to the dynamic range that the human eye can perceive, resulting in a more realistic and superior image quality. The core of TV HDR technology is to improve the brightness of the picture and control the brightness of the dark picture, thereby enhancing the contrast between the light and dark pictures.
HDR display technology can greatly enhance the detail and layering of the picture, making the bright part of the film more clear, the dark part is more deep, and the layering looks clear, creating a natural look that is closer to reality, allowing people to feel and feel Seamless transformation between virtual and reality.
