You mean grayscale, right? Thats (at least in 4-layer grayscale) where you
have 4 shades of pixels: white, light gray, dark gray and black. This is
achievable by switching between to buffers, each one containing a picture.
You display the first buffer for 1/3 of the time, and the second buffer for
2/3 of the time. So if a pixel is off in both buffers, the pixel on the
screen would be white. If the pixel is on in the first one but off in the
second one, the pixel on the screen would be light gray (Since it is on for
1/3 of the time but off for 2/3 of the time, you get the effect of it being
1/3 the darkness of a black pixel). If a pixel is off in the first buffer
but on in the second, it would be dark gray. If a pixel is on in both
buffers, it would be black.
Thats my explanation, somebody can probably do better =)
