Abstract
A display device is described which can be updated by applying pressure with a passive object. The display device comprises a transparent top conductor layer, a middle conductor layer and a bottom conductor layer. The middle conductor layer is segmented into a plurality of independent areas and a pixel of the display device is defined based at least in part on the way that the middle conductor layer is segmented. The display device further comprises an electrophoretic ink layer between the top and middle conductor layers, a layer of piezo-electric material between the middle and bottom conductor layers, and an electrical connection between the bottom and top conductor layers.
