I was reading the news about
http://www.linusdisplay.com/
It's very interesting but what should be the refresh rate of the "line of pixels"?
If we need an image refresh rate at 60 fps and a vertical resolution of 600 lines, it should run at 36.000 Hz!
And, speaking about stereo vision (not line blanking but page-flipping), it shuold be 72.000 Hz!
And the moving mirror have to sync to it!
If I'm not missing something, it sounds a bit incredible!

Hey!
Might be useful!
While we are on this general topic, can anyone explain how "raster film recorders" work?
Isn't it similar? (albeit at a "glacial" speed?)

Interesting thought. Let's assume they designed this for NTSC-TV we get 60 Hz x 480 lines = 28.8 kHz.

Linus says they have CRT and LED solutions. My CRT-monitor does 130 kHz. There are models by Iiyama which do 140 kHz. I just wonder how a one-line CRT display would work and what this would mean for phospor-residue?

LED's should be able to do insane frequencies in the MHz realm.
(Check http://www.devices4less.com/WideArea.html for a 2.8 MHz IR-LED emitter.)

The mirror only has to do the 60 Hz.

So, I see no problems here.
