[akagi1945]

When Dangbei projector F3 released in China, many users have paid attention to the three letters-HLG, which appear on the Dangbei F3 details page, which has not been mentioned in the previous Dangbei projector products. So what exactly is this HLG? Let's take a look.

What is HLG:

HLG, which is called Hybrid Log-Gamma, is a high dynamic range standard jointly developed by BBC and NHK. In fact, HLG is just a standard for HDR. It can display different degrees of HDR effects according to different display devices , and has HDR with adaptive performance. HDR is a high dynamic range image, and there are currently three standards, namely HLG, HDR10 and Dolby Vision. Behind HLG is Sony, BBC, and NHK support.

So what does HLG do?

Its biggest function is to make the details of the picture to be more abundant, and reduce the loss of details caused by the light ratio while ensuring the image quality. For example, in a picture with strong light, the dark part may lose some details. If you have HLG, you can make the dark part more detailed.

​

Application of HLG:

Among the three major standards of HDR, HLG is the most widely used one, the promotion cost will be relatively low, and the acceptance is also relatively high ; but among the projector products, many projectors only support HDR10, and few projection products HLG , like the more popular Nut Projector, Big Eye Orange Projector and Mijia Projector, only support HDR10 single standard. Dangbei projector F3 has the dual standard of HDR10 + HLG, the advantage is that the high dynamic video decoding technology makes the primary colors of the film brighter and dazzling, can easily support 4K ultra-clear decoding, provides more dynamic range and image details, and has a more natural Contrast between light and dark.
