Its anti-aliasing, not sub-pixel rendering. We're probably just thinking of different terms. The anti-aliasing results in wider lines, but pixels at the edge are some grey value between the background and the solid line colour. Sub-pixel rendering for fonts on LCD screen utilises the RGB|RGB|RGB| (example) banding of colours on the LCD to more accurately position the rising portions of glyphs. A white dot could be: |...|RGB|...| Or shifted by 1/3 pixel: |...|.GB|R..| And should in theory still look like a white dot. (In fact, it is programmed as one cyan, and one red pixel next to each other).
