Abstract
A system and a method are disclosed for updating a bi-stable display includes a framebuffer for storing waveforms for each pixel individually. The system includes determining a current state of a pixel of the bi-stable display; determining a desired state of the pixel of the bi-stable display; and updating the pixel by applying a determined control signal to the pixel to drive the pixel from the current state to the final state. Updating each pixel occurs independently of the other pixels of the bi-stable display.
