Patent ID: 8824040

Claim:
A system for an illuminated electrophoretic device comprising: an electrophoretic display having a plurality of microcapsules suspended within a insulating liquid, wherein the insulating liquid is sandwiched between a first surface and a second surface, wherein each microcapsule encapsulates a plurality of charged particles, wherein the first surface is transparent; a light source configured to transmit visible light through the first surface, wherein the visible light is generated by components of the first surface, by components of the second surface, by one or more components positioned between the first surface and the second surface, or by combinations thereof; and a luminescent substance positioned between the first surface and the second surface, wherein the luminescent substance is a part of the light source that produces and emits visible light that is transmitted through the first surface, wherein the luminescent substance is the insulating liquid, is a substance suspended within the insulating liquid, or is contained within at least a portion of the microcapsules, wherein an energy providing component of the electrophoretic device produces energy using a power source of the electrophoretic device, wherein the energy produced by the energy providing component is converted by the luminescent substance into the visible light, and wherein the power source is a battery of the electrophoretic device or is an AC-to-DC power source that provides DC power to components of the electrophoretic device from mains electricity.
