  • Patent number: 6724519
    Abstract: An electrophoretic display having a protective electrode that reduces the degradation of the display caused by mechanical or electrochemical action. The electrode can include a protective layer that reduces the mechanical or electrochemical damage to a transparent conductive electrode. The protective electrode can be a vapor permeable electrode that is a reticulated electrically conductive structure, such as a metal screen or wire mesh, or a reticulated structure coated or impregnated with a conductive material. The protective electrode can include a layer that protects the display media from physical abrasion or removal by mechanical action, while allowing the application of an electric field to cause the display to be addressed.

  • Patent number: 6704133
    Abstract: A display overlay includes a contrast media layer and a photoconductive layer disposed between two electrodes. Light from an emissive display strikes the photoconductive layer and lowers the impedance of the photoconductive layer at the point at which the light is incident. Voltage applied to the electrodes creates an electric field that addresses the contrast media layer in locations of reduced impedance.

  • Patent number: 6445489
    Abstract: Electrophoretic displays include a light-emitting layer, a photoconductive layer, and an electrophoretic layer. The light-emitting layer may be an organic, light-emitting material, or organic, light-emitting diode, which is addressable using a multiplex addressing drive scheme. The impedance of the photoconductive layer is lowered when struck by light from the light-emitting layer. As a result of the lowered impedance of the photoconductive layer, the electrophoretic layer, which itself cannot be multiplexed, is addressed at a lower, subthreshold voltage.
