Subpixel rendering is a trick used when resolution of displays are challenged and small font readability is crucial.
Not to mention some displays that allow the user to rotate by 90 degrees!!! Add to this that some LCDs have the RGB runing along the x-axis and some run along the Y-axis that will totally screw up subpixel rendering. But as you can imagine, this has to be done in the very low level OS font rendering code. Not clear if the patent will ever hold up. So - any way to fine tune sub-pixel rendering in OS X?ĪFAIK, ClearType is patented by MS even though Wozniak did it a long time ago in Apple II.

Now on my previous Windows machine I could only achieve this byĬareful tuning using the tuning tool mentioned in my first post. Having said all that it still seems to me that the OS X sub-pixel rendering compared to what I see on a machine running optimised ClearType is not as clear (no flames pls). 'Standard' is just anti-aliasing, and the light, medium & strong settings use sub-pixel rendering to differing degrees. The 'font smoothing' settings in OS X are using anti-aliasing and sub-pixel rendering. You can also read about sub-pixel rendering on Wikipedia. It is a bit of a kludge solution - but it works - to go the next step after anti-aliasing. Subpixel refers to using the red, green, blue (RGB) 'sub' pixels, which together form one visible (to the eye) pixel, to actually get a higher (apparent) resolution.
