i think there's something odd with this description. (and, as someone who has clearly been confused about the display for some time, i'd like to be sure i understand.) unlike a traditional display, every pixel has a single color. given this, it seems wrong to talk about the "red channel of the first pixel". you either use some of that pixel, or you don't. in effect, the display is implementing sub-(full-color-)pixel rendering all by itself. (which i think is what bert was saying, but the "channel" thing confused me.) with the backlight off, this doesn't matter -- all pixels are the same color anyway. but with the backlight on in monochrome mode, you see a lot of color in single-pixel-width lines. if the line is perfectly aligned with the diagonal of the pixels, it will be completely colored (i just tried it), but mostly you just get a lesser or stronger fringing effect. for backlit ebook mode, this might not matter so much, since ebooks might not have a lot of diagonal single-pixel-width lines, but the effect is definitely there. paul =--------------------- paul fox, [EMAIL PROTECTED] (arlington, ma, where it's 58.3 degrees) _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
