|  Re: Subpixel "rendering" CRT
It's an optical trick your brain does on moving objects. No real higher resolution, just subpixel rendering combined with scrolling. No matter the type of display, all you need is that the refresh rate is synchronized with the routine (50fps)
I first saw it from Crest.

The key is to scroll only one pixel per two frames. And you have two versions of the graphic. A normal version and a half pixel offseted version.
The steps:
Step 0. Show normal graphics
Step 1. Show the half pixel shifted graphic, then scroll 1 pixel to the left, and jump to Step 0
If you didn't scroll, the trick would fail, but scrolling makes your brain see the movement more continuous than it actually is.
