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 electrical connection between the bottom and top conductor layers. 描述了种显示设备，其可以通过利用无源对象施加压力而被更新。该显示设备包括：透明的顶部导体层、中间导体层和底部导体层。中间导体层被分割成多个独立的区域，并且该显示设备的像素至少部分地基于分割中间导体层的方式而被定义。该显示设备进步包括：电泳墨水层，该电泳墨水层在顶部导体层与中间导体层之间；压电材料层，该压电材料层在中间导体层与底部导体层之间；以及电连接，该电连接在底部导体层与顶部导体层之间。
