Encapsulated pixels for display device
View Patent ↗A display device comprising an array of encapsulated pixels. The encapsulating pixel includes an optical element which is altered from a first optical state to a second optical state upon when a potential difference is generated across it. The optical element is in contact with two electrodes which are connected to a pixel driver for generating the potential difference. The encapsulated pixel is hermetically sealed from the environment by a sealing layer and the driver receives power wirelessly via an inductive power transmission system.
1. A method for producing at least one encapsulated pixel for a display device, said method comprising
providing a first substrate comprising a first transparent conductor;
fabricating a first electrode from said first transparent conductor;
fabricating a first inductor on said first transparent conductor;
providing a second substrate comprising a second transparent conductor;
fabricating a second electrode from said second transparent conductor;
stacking said first substrate together with said second substrate;
introducing an active optical material between said first substrate and said second substrate to form a pixel; and
encapsulating said pixel within a sealing layer.
2. The method of claim 1 further including a step of fabricating a second inductor onto said second transparent conductor.
3. The method of claim 1 wherein at least one electrode is a strip electrode.
4. The method of claim 1 wherein the steps of fabricating said electrodes comprise at least one of printing onto said conductors or etching said conductors.
5. The method of claim 1 wherein the steps of fabricating said inductors comprise at least one of printing onto said conductors or etching said conductors.
6. The method of claim 5 wherein the steps of fabricating said electrodes comprise at least one of printing onto said conductors or etching said conductors.
7. The method of claim 6 wherein the steps of fabricating said inductors comprise at least one of printing onto said conductors or etching said conductors.
