Recently, Samsung QLED's optical quality sub-point television has been verified by Verband Deutscher Elektrotechniker (VDE), a world-class testing and certification association, and its ability to restore "100% color rendering volume" has been recognized. Samsung was the first among the global TV manufacturers to claim this title, indicating that the color volume is rapidly becoming an effective indicator of measuring color accuracy.
For more modern displays, such as the world’s first commercially available HDR TV launched by Samsung in 2015, the brightness range has increased significantly, and the white and black expressions are more realistic. At the same time, the color gamut has also been expanded and the picture has become more vivid. We call this new, broader display range high dynamic range (HDR), while the previous display range is called Standard Dynamic Range (SDR).
In the world of SDR, expressing the gamut of a display with a two-dimensional color space has proved to be satisfactory because the calibrated display has a similar performance. The peak brightness is 100 nits, and the colors are usually at the same brightness level - displaying 75% of the peak brightness, achieving better saturation.
But in the era of HDR, the situation was completely different. For example, the peak brightness is usually 5 to 10 times higher than the SDR era, Samsung QLED TV can reach 15 to 20 times. The change in brightness level has a huge effect on the display of colors. For example, if the picture exceeds the monitor's peak brightness, its color may not be displayed correctly, and sometimes it may even cause the picture to appear "fade."
The importance of the color rendering volume In order to adapt to different displays, the brightness is integrated into the traditional 2D color gamut chart as the third dimension, resulting in a color rendering volume. This 3D measurement standard can indicate that the display reproduces color over all luminance levels within its luminance range.

Samsung QLED TV color volume 100%
The color rendering volume is a three-dimensional indicator that indicates the color reproduction capability of a display at all its brightness levels. At the same time, the color rendering volume is an important criterion in ensuring that the content is displayed in accordance with the author's intentions. However, why is the color volume different from other color standards? Let's take a closer look at this new color measurement method. Display Technology Notes
From SDR to HDR: Accurately Measure Color The color standard for many TVs was developed in the CRT TV era and they are limited by the outdated 100 nits brightness level. As a result of this type of standard implementation, the monitor cannot accurately represent colors when reproducing video and images. For more modern displays, such as the world’s first commercially available HDR TV launched by Samsung in 2015, the brightness range has increased significantly, and the white and black expressions are more realistic. At the same time, the color gamut has also been expanded and the picture has become more vivid. We call this new, broader display range high dynamic range (HDR), while the previous display range is called Standard Dynamic Range (SDR).
Under HDR, white and black are more vivid
Today, most manufacturers and calibrators use color gamut to specify and measure the range of colors that a display can reproduce. Specifically, the US film industry uses the DCI-P3 color gamut as a standard for digital cinema projection. In the world of SDR, expressing the gamut of a display with a two-dimensional color space has proved to be satisfactory because the calibrated display has a similar performance. The peak brightness is 100 nits, and the colors are usually at the same brightness level - displaying 75% of the peak brightness, achieving better saturation.
But in the era of HDR, the situation was completely different. For example, the peak brightness is usually 5 to 10 times higher than the SDR era, Samsung QLED TV can reach 15 to 20 times. The change in brightness level has a huge effect on the display of colors. For example, if the picture exceeds the monitor's peak brightness, its color may not be displayed correctly, and sometimes it may even cause the picture to appear "fade."
Even with the same content, the colors displayed on the monitors with different brightness ranges are not the same
So although the two-dimensional color space used to represent the color gamut is sufficient in the SDR era, the situation is completely different in the HDR world where there is a large difference in brightness levels. Therefore, it is necessary to establish a new color standard so as to ensure that HDR content can be correctly produced, played, and displayed, and in accordance with the original intention of the content creator. The importance of the color rendering volume In order to adapt to different displays, the brightness is integrated into the traditional 2D color gamut chart as the third dimension, resulting in a color rendering volume. This 3D measurement standard can indicate that the display reproduces color over all luminance levels within its luminance range.
Unlike the ordinary two-dimensional CIE 1931 color space chart (left), the three-dimensional color volume better measures the color of the monitor
In short, the higher the value of the color rendering volume, the more vivid and accurate the display can be. Samsung QLED TV has "100% color rendering volume" certification, which means that regardless of the brightness level, it can display all the colors in the DCI-P3 color space, to ensure that the HDR screen can faithfully restore the intent of the content producer. Samsung QLED TV with 100% color rendering presents vivid colors
The definition of HDR for consumers includes various performance indicators, such as higher contrast, broader peak brightness levels, and the ability to present a wide color gamut at a wide range of brightness levels, and the color rendering volume will The indicators are all integrated. Undoubtedly, the color rendering volume will further become an increasingly attractive area in the display industry. The future of television is here, and it's colorful!
