Universal display module
First Claim
1. A universal display module comprising:
- a backplane formed with a substrate;
a top plane formed with a conductive transparent substrate;
a pair of spaced apart electrodes; and
a non-volatile ink sandwiched between said backplane and said top plane in contact with said pair of electrodes; and
a conductive adhesive for shorting and securing said top plane to said backplane.

Abstract
A universal display module is disclosed which includes a backplane, a top plane and an ink layer in contact with a pair of spaced apart electrodes to form a display and other optional components, such as a drive chip, a battery, a sensor, a logic chip, membrane switches, RFID antenna and a biometric sensor, that can be incorporated into a wide range of devices. Unlike other known display modules, the universal display module in accordance with the present invention is flexible enough to be used in labels, cards, vacuum formed parts, injection molded parts or other integration techniques, such as hot lamination without modifying the module. As such, universal display module in accordance with the present invention provides economies of scale by allowing for the production of a single robust display module that can be used for a variety of end uses and reduces inventories as well as production costs related to both the manufacturing as well as the integration of the display. As such, the module allows an integrator to use a wide range of common integration techniques, such as hot lamination, label insertion, vacuum forming, cold lamination and injection molding for integrating the display module into an end application. No known display technology exists today which can be used in such a wide range of manufacturing processes.
