Diagram of CoolType's subpixel rendering technique.

Adobe CoolType is a font subpixel rendering technology developed by Adobe Systems, comparable to ClearType from Microsoft and Quartz 2D text rendering in Mac OS X.

Subpixel rendering has been phased out by the industry in favor of more conventional anti-aliasing as higher-resolution displays no longer use predictable grid patterns and gain less benefit from subpixel smoothing.[1][2]
