Among the many features of high-end TVs this year, HDR display technology is undoubtedly the most attractive to us. In the past two years, the 4K ultra-high-definition screen, which has been hot, is talking about the resolution of the TV. The HDR technology emphasizes the human eye's perception of the picture and the improvement of image quality. The human eye's perception of brightness is very wide, from a few thousandths of nits to millions of nits. The final image quality perceived by the human eye is closely related to the final brightness range displayed at the image output. The so-called dynamic brightness range, we can understand it as the area between the highest brightness and the lowest brightness of the screen.
The range of brightness that traditional TV can display is extremely limited, which is far from the range that human eyes can perceive. The reason is that the brightness of the traditional TV in the bright part of the picture cannot be improved, and the dark place cannot be dimmed. As a result, the human eye finally perceives a poor sense of layering and a lot of details are lost. HDR super-quality display technology came into being to solve this problem.
Smart TVs equipped with HDR technology can expand the dynamic performance range of brightness, showing a picture that is similar to the dynamic range that the human eye can perceive, thereby bringing a more realistic and excellent picture quality perception. The core of TV HDR technology is to increase the brightness of the picture and control the brightness of the dark part of the picture, thereby enhancing the contrast between the bright and dark pictures.
HDR display technology can greatly improve the details and layering of the picture, make the bright parts of the film clearer, the darker parts deeper, look clear, create a natural look closer to reality, make people immersed, feel Seamless transformation between virtual and reality.
