This might be interesting tech used in future screens:

They are saying it could work up to 2000hz!
Graphene Display capable of 400 Hz+
Re: Graphene flickers at 400hz
2000Hz 2500ppi.
Oh yeah

Considering 4k @ 27" is about 163ppi...
And 8k @ 27" is about 335.43ppi..
That would be a hell of a monitor.
Sure, I'll take an 8k @ 27" monitor with 2000hz. Not like we have any graphical hardware that can drive it right now but perhaps in another decade or so.

"Membranes in a graphene MEMS can be moved by applying an electric potential and, together with the large optical absorption of graphene (2.3 percent of visible light)"
2.3% of visible light is a "large optical absorption"? How? Or did they mean 2.3% of the EM spectrum (visible light range on a logarithmic scale).

Re: Graphene Display capable of 400 Hz+
They may mean that one layer of the material absorbs 2.3% so a few hundred nm of the stuff can be used as a gate to block light.

Re: Graphene Display capable of 400 Hz+
There can be techniques to amplify that 2.3% into something that has a huge contrast ratio. Whether via using polarizers, via using stacking, etc. They will just have to develop the right technique.
Even - LCDs also happen to be nearly invisible without using a polarizer.

Re: Graphene Display capable of 400 Hz+
As Chief said, LCD is nearly invisible too. Look at this LCD screen that had its polarizer removed, and then looked through a hand-held polarizer:Kheri wrote:"Membranes in a graphene MEMS can be moved by applying an electric potential and, together with the large optical absorption of graphene (2.3 percent of visible light)"

Re: Graphene Display capable of 400 Hz+
Thanks to all 3 of you. Actually looking at the Nature article helps a bit too.
