DisplayHDR True Black 600: New classification for particularly high-contrast OLED displays

Particularly bright and high-contrast OLED displays will receive a new certification in the future. The Video Electronics Standards Association (VESA) is expanding the DisplayHDR True Black screen standard to include the new DisplayHDR True Black 600 classification.

Peak brightness of 600 candela per square meter

For an OLED display to boast the new certification, a peak brightness of 600 candela per square meter (cd/m²) must be achieved at least in the center of the screen. The previous maximum for the DisplayHDR True Black 500 standard was 500 cd/m².

However, displays that meet the new 600 rating must meet additional requirements that are consistently higher than the 500 variant. This includes, for example, a permanent brightness of at least 350 cd/m² (instead of 300 cd/m²). This value also has to be reached in a fraction of a second.

At full brightness, the organic LEDs still have to achieve 0.0005 cd/m² or lower in black reproduction in the DisplayHDR True Black 600 rating. This results in the contrast ratio of 1,000,000:1 and more typical for OLED displays. A DCI-P3 color space coverage of at least 90 percent is also one of the requirements for the new standard.
