Application note on driving E Ink displays from Renesas. Link here (PDF)
E Ink segmented displays are direct drive displays consisting of E Ink Vizplex Imaging Film sandwiched between two electrode layers, the top plane and the backplane, and then encased in an environmental barrier solution to protect the film and the segment electrodes. To get the most from E Ink segmented Displays, you need to be aware of proper design and implementation. Your reward will be sharp, precise images, a pleasant transition from one image to the next, and a long battery life.
