|20130182310||DISPLAY DEVICE - A display device comprising picture elements, which are constituted by electrowetting elements having at least one first fluid and a second fluid immiscible with each other within a space between a first support plate and a second support plate, the second fluid being electro-conductive or polar. The first fluid in each element is at the side of the first support plate confined by element walls, and the second fluid is shared by a plurality of picture elements, characterised by a preventer for preventing first fluid portions from being expelled from its confinement when forces other than electrowetting forces are exerted on this fluid.||07-18-2013|
|20130057941||ELECTROWETTING DISPLAY DEVICE - 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.||03-07-2013|
|20130010348||ELECTROWETTING DISPLAY DEVICE - The present invention relates to a method for making an electrowetting display device comprising a plurality of picture elements and a first support plate and a second support plate. Each picture element comprises a space between the first support plate and the second support plate. The method comprises the steps of: providing the first support plate with an electrode structure; arranging an insulating layer on the electrode structure, the insulating layer having a thickness and a hydropobic surface facing the space; temporarily applying an electric field across the thickness of the insulating layer to reduce permanently the hydrophobicity of a predetermined area of the surface. The invention further relates to an electrowetting display device and a use of an area of reduced hydrophobicity in an electrowetting device.||01-10-2013|
|20120275009||METHOD FOR MAKING ELECTROWETTING DISPLAY DEVICE - The present invention relates to a method of making an electrowetting display device having a plurality of picture elements, each picture element being defined by walls surrounding a display region, the plurality of picture elements covering a first area of a support plate. The method comprises the steps of: applying a hydrophobic layer covering at least the first area; lowering the hydrophobicity of the hydrophobic layer over a second area substantially outside the display regions; forming the walls on the hydrophobic layer over the first area. The present invention further relates to an electrowetting display device.||11-01-2012|
|20120256940||DISPLAY DEVICE AND DISPLAY APPARATUS - A display device has a set of picture elements, one active matrix and a display area, the display area including a first area and a non-overlapping second area, the first area comprising monochrome picture elements, and the second area comprising colour picture elements.||10-11-2012|
|20120256898||DRIVING AN ELECTROWETTING DISPLAY DEVICE - A method of driving an electrowetting display device that includes a display element having a cavity; a first fluid and a second fluid within the cavity, the first fluid being immiscible with the second fluid; a surface facing the cavity; and a first electrode. The display device includes a control system for applying a voltage to the first electrode to provide a display state in response to a signal level of the voltage, wherein the control system is arranged to configure the signal level throughout a display period such that the second fluid adjoins at least a minimum area of the surface, the minimum area being greater than a zero area. The method includes applying at least one display signal level during the display period, the at least one display signal level configured such that the first fluid and the second fluid adjoin the surface throughout the display period.||10-11-2012|
