Abstract:
1. A display comprising: a bi-stable display element comprising a bi-stable material layer, a first conductive layer, and a second conductive layer, wherein the first conductive layer and the second conductive layer are configured to change the state of the bi-stable material layer, wherein the first conductive layer includes first conductive layer segments accessible for electrical contact on a backside of the bi-stable display element, and the second conductive layer includes display electrodes accessible for electrical contact on the backside of the bi-stable display element; and an electrical interconnect substrate comprising display contact pads located on a front side of the electrical interconnect substrate, the display contact pads being located so as to align and form a physical connection with the first conductive layer segments and the display electrodes of the bi-stable display element when the bi-stable display element overlays the electrical interconnect substrate, the display contact pads being physically connected, within the electrical interconnect substrate, to electrical interconnect substrate contact pads, the interconnect substrate contact pads being located such that when the bi-stable display element overlays the electrical interconnect substrate, the interconnect substrate contact pads are exposed to facilitate connecting to a writing unit, the interconnect substrate contact pads also being configured to receive signals to drive the conductive layers to change the state of the bi-stable material layer of the display element.
