A new implementation of Microsoft's TrueType *rasterizer, incorporating techniques for multiplying horizontal resolution by a factor of 3. By addressing individually the red, green and blue subpixels of an LCD display, text becomes much clearer on screen. (The system provides much less of a benefit on CRT screens.) Microsoft is being rather coy about the exact method (as you can see on their official ClearType site), but that has merely intensified speculation about it. In his article, Inside Microsoft's ClearType Font Rendering Technology, Steve Gibson gives a convincing account of how the key technique was developed in 1976 for the Apple II computer.
