(...) Mein Gott! Someone who actually remembers graphics programming on the Apple II! But I remember things a little differently. A pixel was defined in a rather slippery fashion in Apple II "high-resolution" graphics. A pixel was either one bit or (...) (24 years ago, 7-Jun-00, to lugnet.off-topic.geek)

(...) Check this out: (URL). The "pixels" as you describe above aren't really whole pixels at all; rather they are subpixels, much like the red, green, and blue subpixels on a LCD display. This is exactly the concept Microsoft's Cleartype takes (...) (24 years ago, 7-Jun-00, to lugnet.off-topic.geek)

I'm not a TV engineer, but I recall the Apple ][ color distribution was made possible by a trick that used the luminance signal to gate an oscillating chroma signal. The transition from 1 to 0 (or from 0 to 1) was the key that produced a color (...) (24 years ago, 7-Jun-00, to lugnet.off-topic.geek)

(...) MS's Cleartype and the way Woz did Apple ]['s hires graphics mode are a world apart, actually. And the Apple ]['s 1/2-pixel horizontal shifting was the same on color monitors as green/black monitors -- that is, from the same video signal if (...)

(...) I agree that the underlying hardware is completely different, but the net result of having subpixels is similar, and leads to remarkably similar software solutions. (So much so that I hope it counts as prior art, 'cause it is an interesting (...) (24 years ago, 7-Jun-00, to lugnet.off-topic.geek)
