Here's yet another standard for displays as VESA revealed DisplayHDR True Black for OLED panels.
The Video Electronics Standards Association (VESA®) today introduced its new DisplayHDR True Black high dynamic range (HDR) standard, a variant on VESA’s widely adopted High-Performance Monitor and Display Compliance Test Specification (DisplayHDR). The new standard has been optimized for emissive display technologies, including organic light emitting diode (OLED) and future microLED displays.
DisplayHDR True Black allows for up to 100X deeper black levels in addition to a greater dynamic range and a 4X improvement in rise time compared to VESA’s DisplayHDR 1000 performance tier*. This enables a visually stunning experience for home theater and gaming enthusiasts in subdued lighting environments. DisplayHDR and DisplayHDR True Black are the display industry’s first fully open standards specifying HDR quality for LCD and emissive displays, respectively.
VESA also announced today that it has added a new 500 performance level to both the DisplayHDR and the DisplayHDR True Black standards to address the need for thin, ultra-lightweight HDR laptops. The new 500 level includes local dimming as well as the same color gamut, black level and bit-depth requirements associated with the 600 and 1000 levels with a small decrease in luminance compared to the 600 level, to bring about better thermal control in displays for super-thin notebooks. While the new 500 level is optimized for very small, ultra-slim displays, it actually applies to all resolutions and screen sizes, including those used in monitors.
Accelerated DisplayHDR Adoption Sets Stage for True Black
Since its introduction a year ago, VESA’s DisplayHDR standard has seen widespread and growing adoption among LCD display OEMs. To date, nearly three dozen displays across nine display OEMs have been released to market with DisplayHDR certification. Many more are expected to be introduced in the coming months. With the introduction of the new DisplayHDR True Black standard, VESA anticipates a similarly strong adoption curve among OLED display OEMs as has occurred with the DisplayHDR standard.
“Embracing the new DisplayHDR True Black standard, OLED is the ideal display technology for mixing bright highlights with deep, true blacks, so consumers can create extraordinary content or simply appreciate incredibly breathtaking imagery on their PCs,” said Jeremy Yun, vice president, OLED Marketing Team, Samsung Display Company. “The new standard, when coupled with VESA’s DisplayHDR logo program, will show consumers that True Black represents a highly important step in enhancing gaming, TV or movie watching, as well as viewing and editing of photos and videos. Users can see and feel a dynamic range that yields a superior high-end HDR experience.”
Deeper Black Levels with DisplayHDR True Black Standard
On LCD displays, what is considered “black” is actually a dark grey tone, which is a result of minor light leakage common with these displays. VESA defined the new DisplayHDR True Black specification with emissive displays in mind to bring the permissible black level down to 0.0005 cd/m2 – the lowest level that can be effectively measured with industry-standard colorimeters. For gamers and movie watchers in subdued lighting environments, displays adhering to the DisplayHDR True Black specification can provide incredibly accurate shadow detail and dramatic increases in dynamic range (up to 50X depending on lighting condition) for a truly remarkable visual experience.
