Abstract
An electrowetting display device comprises a first support plate comprising a first electrode and a second support plate. A seal connects the first support plate to the second support plate. A first fluid and a second fluid, immiscible with the first fluid, are located between the first and second support plates. A second electrode is in electrical contact with the second fluid. An electrical connector connects the first electrode to the second electrode. A barrier structure at least partly surrounds the electrical connector. The electrical connector and the barrier structure are separated from the first fluid and the second fluid by the seal.
Claims26
An electrowetting display device comprising:
- a first support plate comprising a first electrode;
- a second support plate comprising a second electrode;
- a first fluid;
- a second fluid immiscible with the first fluid, the first fluid and the second fluid located between the first support plate and the second support plate, the second fluid in electrical contact with the second electrode;
- an electrical connector connecting the first electrode to the second electrode;
- and
- a barrier structure at least partly surrounding the electrical connector.
An apparatus comprising:
- an electrowetting display device comprising:
- a first support plate comprising a first electrode;
- a second support plate comprising a second electrode;
- a first fluid;
- a second fluid immiscible with the first fluid, the first fluid and the second fluid located between the first support plate and the second support plate,
- the second fluid in electrical contact with the second electrode;
- an array of electrowetting elements, each electrowetting element of the array of electrowetting elements respectively comprising:
- a portion of the first fluid;
- and
- an electrowetting element electrode;
- an electrical connector connecting the first electrode to the second electrode;
- and
- a barrier structure at least partly surrounding the electrical connector;
- a housing element having a window and a frame surrounding the window, the first fluid and the second fluid viewable through the window;
- at least one processor;
- and
- at least one memory comprising computer program instructions, the at least one memory and the computer program instructions being configured to, with the at least one processor, control a configuration of the portion of the first fluid of an electrowetting element of the array of electrowetting elements.
A method of manufacturing an electrowetting display device comprising:
- depositing a first material on a first underlying layer of a plurality of first support plate layers of a first support plate or a second underlying layer of a plurality of second support plate layers of a second support plate, the first support plate comprising a first electrode, the second support plate comprising a second electrode;
- patterning the first material to form a barrier structure;
- introducing a first fluid and a second fluid immiscible with the first fluid between the first support plate and the second support plate such that the second fluid is in electrical contact with the second electrode;
- and
- depositing an electrical connector to connect the first electrode to the second electrode and for the electrical connector to be at least partly surrounded by the barrier structure.
