HDR stands for High Dynamic Range. The technology displays images with a wider range of colors, brightness levels, and contrast than traditional displays. HDR aims to make images appear more realistic and true to life by reproducing the same brightness and color levels in real-world scenes.
HDR allows for a wider range of brightness levels, from the darkest blacks to the brightest whites, resulting in more vivid and lifelike images. It also provides a broader range of colors, making images appear more vibrant and saturated.
Several standards, such as HDR10, HDR10+, Dolby Vision, and HLG, support HDR. Some standards have different requirements and characteristics, such as the number of bits used to represent the image and the color space they support.
HDR is used in different applications such as video streaming services, games, and displays. It's becoming more common in TVs, smartphones, and monitors, and it's considered one of the most significant improvements in the visual experience in recent years.
