Ask HN: Do OLED displays only save energy with absolute black?

That’s not true; just a very persistent myth. Your intuition is correct. Anandtech display reviews have actual measurements if you’re interested.

See this chart: https://images.anandtech.com/doci/9394/luminance-curve.png

From this article: https://www.anandtech.com/show/9394/analysing-amoled-power-e...

What’s actually true that most people don’t expect is that OLED displays often use more power than LCD displays even with very dark content.

Thanks, from that I understand the brighter the color the more power it will use. So #010101 will use more than proper black but far less than proper white.

That was my question, thanks a lot

Interesting article. I was surprised by how linear the luminance-power curves actually are.

Those charts are very old. Modern OLED are much better.
