Anti-Aliasing is a different technique that’s makes sharp edges look softer by adding more grays, but generally it’d not add other colors as you see here. We also don’t generally apply AA to small text as we actually want it to look crisp.
Sub-Pixel Rendering exploits the fact that each pixel of a typical LCD is made up of three color in a horizontal row.
If you had a perfectly white screen and wanted to add one black dot, the simplest way is to turn off the RGB of a single pixel. However you could also get the same effect by turning off the GB of one pixel and the R of the next pixel. This allows you to move the dot by 1/3rd of a pixel. This is what get exploited to make text more legible.
This is definitely Sub-Pixel Rendering.
