The advent of sub-pixel rendering technologies is stirring up controversy as to the meaning of resolution in a display.

Traditionally, pixel resolution has been counted as the number red, green and blue sub-pixels that are needed to create a full color pixel. But sub-pixel rendering techniques can share sub-pixels creating new ways to display pixels. This white paper discusses various sub-pixel rendering techniques and their implementations.
