That explanation is horrendously wrong. Please do not perpetuate the rumor of "modes" in the display hardware. There are none. And, there is no "refractive screen magic", that idea did not make it into production. The backlight uses regular r/g/b color filters. The blur you see in color mode is the DCON performing anti-aliasing by adding color components from the four neighboring pixels into each pixel (e.g., for a red pixel it takes the red components of the surrounding pixels into account, etc). In early DCON drivers it was possible to toggle the anti-aliasing independently of the backlight intensity, so you could clearly see its effect. IIUC this capability has now been coupled to the backlight intensity, which is fine in regular use, but takes away the possibility to easily demonstrate what's happening. - Bert - _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
