Black line interleaving

[Zerion]

I don't know if this is a new idea, but a quick google search didn't come up with anything, so I thought I'd make quick demo myself.

Demo
web (needs to run in sync with display, does not work in firefox for me)
windows x64 (double click window for fullscreen)

Seems to give the same blur reduction as black frame insertion, but without perceived increase in flickering. Looks better at higher refresh rates, but works reasonably even at 60 Hz.

Essentially, instead of blanking every second frame, it's blanking every second line, alternating even and odd lines between frames, producing output similar to analog interlaced video.

Interesting but looks darker then bfi and does not seem any less flickery to me.

I guess it could subjective or just not work on all displays. I personally don't see any flickering with this and the brightness is the same.

It could also be the web version just doesn't work correctly, I added a native windows build to the post that should be more likely to work correctly.
