Abstract
A mounted display assembly comprises a flexible substrate that supports both display elements and control circuits. The display assembly generally comprises: an electrical connection formed on the flexible substrate, the electrical connection having first and second contact pads; a display element in electrical communication with the first contact pad; and a control circuit mounted on the flexible substrate and in electrical communication with the second contact pad. In a preferred embodiment, the display element comprises a microencapsulated electrophoretic display medium. In another preferred embodiment, printing processes are employed in manufacturing methods for the display assembly.
Claims18
A method of manufacturing an electrophoretic display assembly, comprising the steps of:
- providing a flexible substrate;
- forming upon said substrate an electrical connection having a first contact pad and a second contact pad spaced from one another;
- mounting upon said substrate a control circuit in electrical communication with said second contact pad, said control circuit not being in electrical communication with said first contact pad except via said electrical connection;
- and
- providing an electrophoretic display element in electrical communication with said first contact pad, said electrophoretic display element not being in electrical communication with said second contact pad except via said electrical connection.
A method of manufacturing an electrophoretic display assembly, comprising the steps of:
- providing a first flexible substrate;
- forming upon said first flexible substrate an electrical connection having a first contact pad and a second contact pad separated from each other;
- mounting on said first flexible substrate a control circuit in electrical communication with said second contact pad but not in electrical communication with said first contact pad except via said electrical connection;
- providing a second flexible substrate;
- disposing upon said second flexible substrate an electrophoretic display element;
- and
- disposing said first flexible substrate adjacent said second flexible substrate so that said first contact pad addresses said electrophoretic display element.
