Answers.Text: Sub-pixel rendering (as defined by directly addressing sub pixels of a display) is a form of anti-aliasing. But not all anti-aliasing is sub-pixel rendering.

  [Cleartype](http://en.wikipedia.org/wiki/ClearType) is Microsoft's subpixel rendering technology for improving text clarity.
  
  I recall it being used as a selling point for MS Reader and .lit format back when it was introduced.
  
  Are similar technologies used in modern book readers (either in the reader app itself, or underlying OS)?

  On devices that use eInk, there are no subpixels like the Red, Green and Blue subpixels that can be separately addressed on color screens. Hence there is no subpixel rendering as such on eInk devices (as [stated](http://arstechnica.com/apple/2012/04/why-the-new-ipads-retina-display-loses-the-battle-in-the-e-reader-wars/) by Sriram Peruvemba (chief Marketing Officer at E-Ink Holdings).
  
  3rd generation iPAD has subpixel rendering according to the same [article](http://arstechnica.com/apple/2012/04/why-the-new-ipads-retina-display-loses-the-battle-in-the-e-reader-wars/), but it is not supported by every application.
