Abstract
A method and apparatus for displaying data on bi-stable and non-bi-stable displays is provided. The apparatus includes a controller chip capable of being connected to a non-bi-stable display through a first interface channel and also capable of being connected to a bi-stable display via the first interface channel and an additional second interface channel. When connected the non-bi-stable display, the second interface channel is not connected. The second interface channel may carry mode information bits to the bi-stable display module to allow the bi-stable display to utilize power-saving features.
