High Dynamic Range (HDR) technology is a significant advancement in display technology. It enhances the quality of an image or video by increasing the contrast between the lightest whites and the darkest blacks.
This results in an image that is closer to what the human eye would see in real life. HDR content on HDR-compatible displays can get brighter, darker, and show more shades of gray in between than non-HDR content.
The Video Electronics Standards Association (VESA) has introduced DisplayHDR and DisplayHDR True Black specifications. These are the display industry’s first fully open standards ensuring consistent HDR quality for LCD and emissive displays.
It includes various performance levels, such as each specifying different requirements like brightness, color gamut, bit depth…
These levels help consumers understand the HDR capabilities of a display before purchasing it.
The main difference between DisplayHDR and DisplayHDR True Black lies in their target display technologies and their performance requirements. While DisplayHDR is for LCD displays, DisplayHDR True Black is for emissive display technologies like or Micro LED displays.
standard requires a black-to-white response time of only 2 frames for OLEDs, as opposed to 8 frames for LCD.
This reflects the difference in technology, LED backlights in an LCD takes time to ramp up, whereas OLED is virtually instantaneous.
