  • Systems and methods for improving a fluid contact layer in an electrowetting element
    Patent number: 10185142
    Abstract: An electrowetting element comprising a first fluid and a second fluid immiscible with the first fluid. A support plate comprises a first layer comprising a migration pathway, the first layer comprising a first surface in contact with at least one of the first fluid or the second fluid. A substance is disposed within at least a portion of the migration pathway in the first layer. The substance is distinct from both the first fluid and the second fluid and is configured to reduce migration of at least a component of the first fluid or a component of the second fluid into the migration pathway in the first layer.

  • Electrowetting device
    Patent number: 9495919
    Abstract: A method of manufacturing a support plate for an electrowetting device includes providing a first hydrophobic layer on a substrate, reducing the hydrophobicity of a surface of the first hydrophobic layer and providing a second hydrophobic layer on at least part of the surface with reduced hydrophobicity.

  • Electrowetting display device
    Patent number: 8896904
    Abstract: A method for making a support plate for an electrowetting device includes providing the support plate with a hydrophobic layer; arranging a pattern of hydrophilic material on the hydrophobic layer; and removing a surface layer of the hydrophobic layer by a solvent. The electrowetting device may include a support plate with a hydrophobic layer having a thickness, and a pattern of hydrophilic material arranged on a first area of the hydrophobic layer, the thickness of the hydrophobic layer being larger within the first area than outside the first area.
