Abstract:
Systems and methods are disclosed for pressure-sensitive, electrophoretic displays, which may optionally include haptic feedback. A display may comprise a first conductive layer having a pressure-sensitive conductivity and an electrophoretic layer positioned adjacent to the first conductive layer, wherein the electrophoretic layer is in electrical communication with the first conductive layer and is configured to locally change state based on a pressure applied to the first conductive layer. Local and global writing and erasing of the display can also be achieved.
