For the last couple of years, resolution has been the key battleground in television specs. Now one Dolby executive has indicated that the next battleground might be over brightness rather than pixels.
Although the current standard that needs to be reached for Ultra HD Premium's HDR specification is 1,000 nits (where one nit is equal to the amount of light a candle produces), Giffis believes television manufacturers will soon go much higher.
“Have no doubt about it, the nits race is on. It will be 2,000 nit displays, and I suspect before too long, 4,000 nit consumer displays,” he said.
A bright future
Brightnesses above 1,000 nits might not initially seem that beneficial, but Giffis said that going beyond this brightness would have a positive impact upon a television’s colors, allowing them to become much richer and more saturated.
This happens because of the fact that the color white is made up of the full brightness of its constituent colors. That means that, for example, the brighter a blue pixel gets, the closer it gets to white.
By limiting the brightness of a white pixel to 1,000 nits, you limit how bright a blue pixel can get before losing its color and turning into white. A brighter display allows colored pixels to maintain good color saturation even at bright levels.
In fact, the executive cited Dolby experiments which said that viewers can perceive a brightness benefit in excess of 10,000 nits, ten times the current UHD Alliance HDR brightness specification.
The race is on
We’re already seeing evidence of this race taking place. LG’s latest flagship is advertised as being 15 percent brighter than last year’s OLEDs, and Samsung’s new QLED sets offer a peak brightness of between 1,500 and 2,000 nits.
So when you’re looking to next upgrade your television keep an eye on its maximum brightness, because it might end up being the new battleground now that 4K resolutions have gone mainstream.
