To understand HDR10+ in projectors, we need to have a simple understanding of HDR and HDR10. Let's start with HDR, which stands for High dynamic range. HDR is an image optimization technique that allows for brighter images, higher contrast, and more detail in dark areas. For display devices, HDR can be used to adjust the brightness of the screen and increase the contrast between the brightest and darkest parts of the picture to make the picture more layered and expose more detail.
HDR10 is the upgraded version of HDR. HDR10 can increase the brightness of the picture twice, while deepening the contrast between color differences, and the color content can be adjusted nearly 10 times higher than HDR. The definition of "10" comes from 10-bit color depth. Currently, HDR10 is the most basic HDR standard and does not charge royalties.
The HDR10+ is an upgraded version of the HDR10, which has a maximum brightness of 1000nit, while the HDR10+ has a maximum brightness of 4000nit, which also enhances contrast. The difference between HDR10 and HDR10+ is the processing mode. HDR10 uses static data processing, while HDR10+ uses dynamic data processing. The advantage of dynamic data processing is that it allows it to change for each video frame, meaning that each frame has its own brightness and contrast data.
The birth of HDR10+ is mainly developed by Samsung for the purpose of marking dolby Vision, and it is the only HDR standard that supports dynamic data metadata structure at present. The difference between the two is that Dolby Vision needs to charge a certain copyright fee, and HDR10+ is an open standard. In recent years, the development of HDR10+ has been rapid, and more and more display devices have been certified, and most of the projectors released this year have upgraded HDR10 to HDR10+. We found a projector that supports HDR10+(Dangbei X3) And a projector that does not support HDR for comparison.
