VESA Introduces DisplayHDR True Black High Dynamic Range Standard for OLED Displays

VESA Introduces DisplayHDR True Black High Dynamic Range Standard for OLED Displays

DisplayHDR True Black enables up to 100X deeper black levels for gaming and home theater applications; VESA also adds new 500 level for ultra-thin HDR laptops with local dimming.

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.

"When VESA unveiled the original DisplayHDR standard, we recognized that display technologies were quickly evolving, and we immediately set to work on developing a new open HDR standard for OLED and other emissive display technologies," stated Roland Wooster, chairman of the VESA task group responsible for DisplayHDR, and the association's representative from Intel Corporation for HDR display technology. "On behalf of all of the VESA member companies that contributed to the DisplayHDR True Black specification, I'm pleased to say that we are fulfilling our promise with today's announcement. We're extremely proud of this incredible, high contrast and high dynamic range standard. Consumers benefit from the transparency of the DisplayHDR True Black specification and logo, which makes it clear that they're getting a display that yields huge performance improvements in subdued lighting environments."

Added Wooster, "We're also very excited to include the new 500 performance tier for the DisplayHDR and DisplayHDR True Black standards, which provides true local dimming, high color quality and a high contrast ratio at the lowest price point and thermal impact for display OEMs. This combination makes the 500 level ideal for ultra-thin notebook designs, but it's equally applicable to monitors as well."

These low-black-level HDR standards are all nice and all, but personally I would always favor a "true" HDR setup with higher brightness. For gaming, even an illuminated keyboard can reduce the benefits from lower black levels, not to mention that fully dark rooms are not something everyone has access to.

But I suppose the OLED makers are pushing VESA to do this, so they can slap badges on their displays as well.

I personally prefer good blacks and contrast that bigger brightness values.

Lol, only lg and sony are making oleds (outside phones/tablets), and i know sony isnt pushing it (i work for them). Cant speak for lg tho.

And im not blind, so will always prefer improvements on blacks, rather than brightness.

There is nothing "truer" about the HDR of a bright LCD monitor. Even those 2000 dollar 144hz FALD monitors can't break 1500:1 ANSI contrast. Rtings rates their HDR capability as being marginally better than the CHG70, and fairly mediocre overall. There is absolutely nothing "HDR" about that. There's a reason that the OLED televisions win best HDR television at the VE shootout every year despite there being LCD TV's that can get 3 times as bright. What you want, is a bright monitor. There is nothing specifically HDR about being bright. It's the combination of being bright while producing dark blacks at the same time that makes for a good HDR display.

Except that the full range of dark blacks as seen on OLEDs does require a fully light-controlled room to really stretch its legs. So while it may win awards with "measured" performance, for many people with average viewing setups, the situation is quite different.
I'm sure plenty people will say something like "But HDR is meant to be played in a dark room", but shrug, thats not something everyone can or wants to invest into (or only play at night).

Anyhow I haven't really kept up with HDR gaming monitor contrast, but LCD HDR TVs can do 6000:1 contrast at ~1500-1600 nits of peak brightness (for small highlights, of course, as HDR would use it) without FALD, or 20000:1 with it.
