Abstract
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.
Claims10
A display device comprising at least one encapsulated pixel, said encapsulated pixel comprising:
- at least one optical element having at least two optical states, at least two electrodes;
- a driver for generating a potential difference between said electrodes such that said optical element is altered from a first optical state to a second optical state;
- and
- a sealing layer configured to hermetically seal said encapsulated pixel;
- wherein said driver comprises at least one secondary inductor connected to said electrodes and configured to inductively couple with an external primary inductor wired to a power supply.
