Abstract
A method for making electrophoretic displays layers including various thin films that are deposited directly onto a layer of microcapsules of electrophoretic media. In an embodiment, a thin film of a light-transmissive conductive material is deposited to create a clear front electrode for an electrophoretic display. In some embodiments, both a dielectric layer and a thin film of a light-transmissive conductive material will be deposited onto the microcapsules.
Claims8
A method of making an electrophoretic display layer comprising:
- providing a first substrate;
- depositing a layer of capsules comprising electrophoretic media on the first substrate, thereby creating a contoured surface of the layer of capsules on the side of the layer of capsules opposite to the first substrate;
- depositing a dielectric layer on the contoured surface of the layer of capsules comprising electrophoretic media;
- and
- depositing a layer of light-transmissive conductive material over the dielectric layer previously deposited on the contoured surface of the layer of capsules.
