The 4K-level HD lens, HDR, and high dynamic contrast for long-distance photography at 10 meters. The performance on the screen is that it can take care of the dark and high-brightness details at the same time, bringing a dynamic range closer to human vision. Ordinary TVs, projectors and other display devices have limited contrast performance due to the brightness limit, which is the SDR (Standard Dynamic Range) level. Generally, the contrast ratio of the LCD screen of our mobile phone is only 1000:1. With the introduction of HDR, a wider contrast ratio of 100,000:1 can be achieved.
