Claim Text:
1. A method of driving a display pixel comprising at least four sub-pixels, the method comprising: determining a first projection of an original color signal onto a color space defined by a first and second sub-pixel of the at least four sub-pixels; determining a second projection of the first projection onto a second color space defined by a third sub-pixel; driving the third sub-pixel based on the magnitude of the second projection; driving the second sub-pixel based on the difference between the first projection and the second projection; and driving the fourth sub-pixel based on a component of the original color signal; wherein the first sub-pixel is not activated while driving the third sub-pixel based on the magnitude of the second projection and driving the second sub-pixel based on the difference between the first projection and the second projection.
